The theater begins with a hanger, and the city with public transport. In recent years, more and more attention has been paid to the convenience of moving around cities and regions, the accessibility of all their corners for both residents and tourists. guest wifi solutionsAll attempts to solve this problem by traditional methods have failed. Hope only for smart transport.
The topic of smart cities in recent years has become one of the most discussed at all IT events and, perhaps, has surpassed even recent favorites in popularity: big data and blockchain. Perhaps the reason lies in the fact that the rather futuristic benefits of these technologies fade before the real benefits that the most understandable component of a smart city already brings – SMART Transport. wifi6 wireless solutions
The obvious benefits of smart transport
Residents of cities where an intelligent transport system has been created or some of its elements have been introduced can feel with their own hands and experience the changes in the transport situation in general and in the operation of public transport in particular. Check with a mobile application or look at the scoreboard when the bus you need comes up, choose a convenient payment method and the most favorable fare. Find a free parking space in advance and pay it not only in cash, but also with a card, mobile phone, etc. To see how, after the appearance of cameras on the roads that record violations of the rules of the road, drivers become more accurate and polite. outdoor wifi solutions Can all these clear and obvious benefits go unnoticed?
It is clear that, depending on the scale and financial capabilities of the city or region, an intelligent transport system can be created in it faster or slower. The list of components is also significantly different. However, in any case, the appearance of even individual elements of this system almost immediately makes the city more convenient and attractive not only for its residents, but also for guests wifi solution.
Intelligent Transport System
The implementation of Intelligent Transport System (ITS) hotel wifi solution today is a necessary step in many respects: traffic jams, traffic accidents, public transport and increasing number of people in the city. The advent of the intelligent transport system made it possible to optimize the work of traffic lights, public transport, automatic recording of violations, organize paid parking lots and online monitoring of traffic conditions.
To manage the intelligent transport system, the most modern Situation Center in Europe has been created. In addition, ITS is also communication channels, data transmission system, software and information security system. According to the data center, thanks to the introduction of ITS, the number of deaths in road accidents in the capital over the past 10 years has decreased by 2 times, and the average speed during peak hours, despite the increase in the number of cars, has increased by 16% over the past 7 years.
One of the most effective components of an intelligent transportation system is smart cameras. The drivers are already used to the fact that they record speeding and compliance with parking rules. However, the list of their skills is gradually expanding. guest-wifi solutions Not so long ago, cameras that send fines for driving along a designated lane or on the side of the road, lane-by-lane change over a solid line, pedestrians not passing on a zebra, leaving for waffle marking or for a stop line, driving for a red signal traffic light.
In addition, the cameras have already taught to identify drivers who drive without compulsory motor third-party liability insurance and who have not undergone inspection. Another important component is traffic intensity sensors installed on public transport. Together with photo and video recording cameras, they provide an opportunity to get the most complete picture of the traffic situation on the roads – to assess the traffic intensity, speed of cars, identify problem areas and places where accidents most often occur or congestion occurs. And of course, tell passengers when the bus they need comes.
It is clear that the work of all these devices is based on software based on artificial intelligence and machine learning technologies. cloud managed wifi solutionsThe most common technology that is now used in digital vision is the use of neural networks. At the household level, training in neural networks is similar to human training. Photos with a certain sign are fed to the entrance, the network remembers them and can find them among other images. Cars, trucks, people’s faces – objects can be different. Search, classification, clustering – the range of tasks is multifaceted, but the principle remains same. The more “training” photos, the better the network works.
One of the most important functions of the state is to ensure the safety of citizens. And here smart transport also comes to the rescue. Constant video surveillance of what is happening at the station, bus station, metro, and also in public transport salons significantly reduces the likelihood that an attacker will be able to freely do his dirty work. Moreover, video cameras are becoming more intelligent and already know how to recognize suspicious faces and emergency situations. Citizens are also gaining more opportunities – they can quickly call the police or ambulance using special emergency call columns or the Passenger-Machinist device.
Data from devices installed on public transport enriched with information about the movement of city residents received from mobile operators or from a single city fare payment system is an invaluable source of information on the basis of which you can plan new transport routes or optimize existing ones. And the social effect of such optimization is hard to overestimate.
It is obvious that in developing the concept of creating a smart city, one can not do without such an important component Wireless connectivity. WiFi has become a driving force when it comes to connecting devices, sharing data and exchanging information. A network of physical devices, traffic management, smart traffic lights and the distribution of cars in parking lots and other items that are embedded with electronics, software and connectivity enabling them to connect and share.
Recently, the question of the future of Wi-Fi guest wifi solutions networks has been increasingly discussed in connection with the expected mass construction of fifth-generation cellular networks. Indeed, why do we need Wi-Fi in a world where cellular networks provide billions of people with high-speed Internet access? Will the 5G family of Wi-Fi standards stop developing? Will technology leave the market by completing its “historical mission”? Everyone who answered these questions in the affirmative is dedicated to this article. Everyone else who understands network technology, we hope, it will also be interesting to read.
Despite the apparent importance and consistency, the questions about the rivalry between Wi-Fi and 5G are based on an artificial opposition of related technologies, but different in wifi6 wireless solutions application models. Most statements about the fragility of Wi-Fi belong to representatives of mobile operators, at the end of the article we will explain why .
In the meantime, let’s try to dispel two misconceptions together – “5G is much faster than Wi-Fi” and “Wi-Fi will die very soon.” First, let’s go back in time and figure out what 5G is and what Wi-Fi is.
By 5G, they mean a new generation of mobile communications standards, which, as many believe, will make a new revolution in telecommunications. Meanwhile, a similar view regarding 4G at the time was perhaps more justified. Compared with 3G 4G, it increased the outdoor wifi solutions data transfer speed by an order of magnitude, the technology received a completely new radio interface, a new architecture of the core network and a lot of new opportunities for operators (and, as a result, for subscribers). In the case of 5G, there are many changes and improvements, and some of them are very radical. But there is one important fact that is rarely talked about: based on 5G standards, cellular networks of three different categories will be created. These are 5G networks for traditional scenarios of using a cellular network in the 1-6 GHz bands, networks for continuous coverage of the territory and the Internet of things (IoT) at frequencies below 1 GHz and millimeter-wave networks. wifi solution And only the first of these three types of 5G will be widely available for ordinary mobile subscribers in the foreseeable future. The other two types will have special usage patterns, which we will also talk about.
But first about the burning issue – about “supersonic speeds” for subscribers. 5G networks operating in more or less familiar frequency ranges from 1 to 6 GHz will be designed for mass servicing of ordinary subscribers. At higher frequencies, it is almost impossible to provide continuous coverage with a limited number of powerful base stations (macro cells). hotel wifi solution Unfortunately, there are few free frequencies below 6 GHz, and this is a worldwide problem. With 3G and 4G, we have already gone through and continue to go through the conversion of parts of the spectrum, the transfer of various kinds of consumers to other frequency ranges, in the future, frequency re-framing from older standards to newer ones. Obviously, there is no magic new source of free frequencies for 5G in the usual ranges. Actually a large group of new 5G solutions is precisely aimed at mitigating the problem of a lack of frequency resources. The goal of new ideas and technologies in cellular communications is always to increase the capacity and speed of the network without significantly increasing its cost. What exactly can you come up with to approach this goal? And what exactly does 5G offer for this?
Wi-Fi to the rescue
To increase the capacity and speed of the network, new frequencies could be obtained. As already mentioned, by and large, there is nowhere to take them from, so cellular communication is trying to go into the ranges that are occupied by other technologies. In 5G, methods for using guest-wifi solutions Wi-Fi frequencies with cellular communications , which already have a number of implementations in 4G, are further developed . For Wi-Fi in the world, quite large sections of the spectrum (hundreds of megahertz) in the 1-6 GHz band are allocated, and mobile operators have been hunting for them for a long time.
But you simply can’t take these frequencies from public networks, so a family of technologies is being developed that allows using these frequencies simultaneously for Wi-Fi and cellular communications, without significant harm to the quality of Wi-Fi. This is an interesting trend. From the simple reuse of the shared band in LTE-U technology (poorly coordinated and harmful Wi-Fi), the development went first to LAA technology (supported by 3GPP Release 13), using the Listen Before Talk (LBT) principle, and then to the LWA and eLAA standards. They no longer simply determine the method of sharing frequencies, but also describe the direct coordination technique (through integration and data exchange) of Wi-Fi and cellular radio subsystems (supported with Release 13 and 14, respectively). Here the most important trend is the coordination and cooperation of cellular networks and Wi-Fi. Remember him. cloud managed wifi solutions Will these technologies affect the expected speed and capacity of cellular networks? Of course, with the help of this trend, a certain increase in these parameters can be ensured, but a revolution here should not be expected.
5G Growth Hormones
If there are not enough frequencies, you need to increase the spectral efficiency- in the same frequency band transmit more data in one channel. Here 5G is better than 4G due to updates in the modulation and coding schemes of the signal, but no radical progress can be expected. Modern modulation systems are already close to physical limits and the practically achievable spectral efficiency of cellular communications in a single channel cannot be radically increased. By the way, in the transition from 3G to 4G, the increase in the spectral efficiency of a single channel was more significant than expected in the transition to 5G. Nevertheless, there is still a significant potential for increasing the efficiency of using the frequency band for the provision of services, but it is realized by more complex means. This is the distribution of the frequency resource between network services, more efficient division of the resource between the upstream and downstream data transmission channel, self-organization of the network, resource recombination and cell coordination, improved support for multi-frequency (carrier aggregation), etc. All this will be actively used in 5G and will have a positive effect, but most of these approaches are already present and developing in the fourth generation.
If it is impossible to radically improve the efficiency of using a single channel, it is logical to try to organize simultaneous exchange of different data streams between the network and the subscriber or subscribers in the same frequency band. In other words, it is necessary to increase the level of reuse of the frequency resource. To do this, data channels operating in the same frequency must be isolated from each other in order to avoid mutual interference. There are several approaches to solving this problem, mainly used for a long time in existing cellular networks and further developed in 5G.
The growth in the capacity of cellular networks has always been ensured by a combination of the three factors listed above: the expansion of the spectrum used, the increase in spectral efficiency and the increase in the frequency reuse level. Over the past two decades, the focus has been on reuse techniques and they have contributed a major increase to capacity expansion. According to various estimates, over the entire period of the existence of cellular communications, the capacity due to the frequency resource has grown 3-4 times, due to the increase in spectral efficiency by 5-6 times, and due to improved use of frequencies – by 40-60 times.
All of the above can give a significant increase in the capacity of 5G cellular networks operating in standard frequency ranges compared to 4G, but cannot give any breakthrough growth in the communication speed available to an individual subscriber. The concepts of capacity and data rate in a cellular network are closely related, but not equivalent. The increase in the number of subscribers that the network can serve without loss of quality does not mean that the network will work much faster for each individual subscriber in real conditions.
It must be emphasized that to get a significant effect from the innovations described above, you will have to install more base stations, connect them to packet data networks with increased bandwidth, use much more complex and expensive antenna systems and get more spectrum. No magic very large investments are needed and they usually invest wherever there is a business. For mobile operators, it is not yet clear why to invest huge amounts of money in the mass segment of 5G networks with continuous coverage and high capacity.
Network for IoT and Superior 4G
Let us briefly dwell on other types of 5G networks. The most important of these is the inter-machine communication network or IoT (Internet Of Things). Here 5G has great advantages over previous generations of cellular communications. This is, first of all, a low level of delay (an order of magnitude lower than in 4G) and the ability to serve a very large number of subscribers in the coverage area of one cell. 5G standards include communication protocols of the LPWA category (Low Power Wide Area), which are designed for low-speed, low-intensity communication of a very large number of subscribers at a very low level of power consumption of modems. Thanks to the architecture and parameters of 5G, it is possible to build not only sensor networks (combining different sensors and actuators, for example, urban systems), but also highly reliable vehicle control systems (cars and drones) and various robots and robotic complexes. IoT 5G networks will mainly be built at frequencies below 1 GHz, where the area covered by the signal of one cell is much larger than at higher frequencies. At the same time, high-speed communication at these 5G frequencies for ordinary subscribers is unlikely to be available, due to lack of spectrum and because Massive MIMO at frequencies below 1 GHz is difficult to use due to the large size of the antennas.
The third type of 5G network is designed to provide subscribers with very high speed communications. This is about peak speeds of up to tens of gigabits per second. These are networks in the high-frequency ranges with wavelengths less than one centimeter (millimeter ranges) that have never been used for cellular communications before. The reason for deciding to include these ranges in the 5G standard is that they have very large unallocated spectral regions (many hundreds of megahertz).
A lot of people who argue about a significant increase in communication speed in 5G do not fully realize that ultrahigh speeds will be available only in millimeter-band networks. The signals of these frequencies are distributed in such a way that direct visibility between the antennas of the transmitter and receiver is almost always necessary for communication (that is, the signal practically does not go around obstacles), and the allowed (and technically available) radiation power is very small. This means that in the conditions of the city to build a field of continuous coverage in the millimeter range, you need to install a huge number of small cells.
Publicly available estimates show that for large cities the number of cells will need to be increased 500-1000 times, compared with the number of cells sufficient to form coverage in standard ranges. Unfortunately, even this will not ensure continuity of communication (the subscriber is unsuccessful enough to turn around to block the signal from the base station). There is no other practical way to create a continuous cover (except for projects using drones and balloons). That is, the 5G millimeter-wave network with continuous coverage in the city will turn out to be very expensive, it is almost impossible to reuse the existing infrastructure and it is poorly suited for ordinary subscribers who move freely in the coverage area. In addition, there is no subscriber equipment for communication in the millimeter range, suitable for embedding in standard smartphones and tablets, and in the near future they are unlikely to appear. For the above reasons, this type of network will be used in the medium term to solve various tasks of transmitting data to stationary (for example, houses) or regularly moving (trains, cars, city transport) objects, as well as for organizing individual hotspots, but not for ordinary ones mobile subscribers.
These are far from all 5G features, but an intermediate conclusion can already be formulated. In the medium term (we would estimate it at 5-7 years, but this is a subjective assessment), subscribers will not receive any revolutionary effect from the construction of 5G networks. Their user experience with the advent of smartphones and 5G-enabled coverage areas will improve due to a higher and more stable network performance and a higher data transfer speed available to them. During this period, 5G networks will be perceived by subscribers, rather, as an improved 4G. The data transfer rate when covering 5G and a device supporting it (we are not talking about the pace of appearance of 5G devices on the market) will usually be higher, but will remain in the same order of magnitude. If now in ideal conditions you can see peak speeds above 100-150 Mbps in commercial LTE networks,
5G in buildings
Above we considered cellular networks outdoors. The indoor situation has a number of features. It is there that most of the traffic is consumed, including mobile. Therefore, it is important for mobile operators to provide high-quality coverage and high network bandwidth in urban buildings. Since the most probable spectral regions available for 5G communication will be located in the vicinity of 3-4 GHz, macro-cells located on the street will not be able to form high-quality coverage inside urban buildings due to the strong absorption of the radio signal at these frequencies in the walls. Therefore, the 5G signal will have to come from antennas located directly in buildings. Indoors, the use of high-order MIMO, as a rule, does not have technical and economic meaning, therefore, indoor 5G will use small cells and antenna systems similar to those used today for 4G indoor networks. For this reason, the data transfer speeds that will be available in rooms of 5G subscribers at frequencies below 6 GHz will be the same order that can be obtained today in 4G indoor networks.
Currently, most of the traffic consumed by users of smartphones and tablets is not created on cellular networks, but on Wi-Fi networks. For example, according to Mediascope in Russia, 78% of mobile device traffic goes through Wi-Fi and only 22% through cellular networks. And this traffic is mainly consumed indoors. To change the situation, it is necessary not only that the cellular network provides a higher data transfer rate than Wi-Fi (this is often the case now), but also that this speed is available in public places, and in the homes and apartments of subscribers. Solving this problem for 5G will require a huge investment in the construction of indoor networks, including in residential buildings.
Wi-Fi is no worse than 5G and that’s why
Now, after a brief educational program about 5G, consider the main issue. And how is Wi-Fi different from 4 / 5G and how is it, in fact, worse or better than cellular? The idea of Wi-Fi as a technology is largely shaped by the experience of using existing public networks, which are arranged very primitively. Meanwhile, modern Wi-Fi is capable in the field of data transmission of practically everything that cellular networks are capable of. Wi-Fi fully supports mobility, allowing you to build continuous coverage areas and serve moving subscribers, service classes, automatic network authorization, advanced data protection, automatic roaming between Wi-Fi networks of different operators.Moreover, both the 3GPP cellular standards and the IEEE Wi-Fi standards provide many means for sharing and coordinating the work of Wi-Fi and 4 / 5G. These are the previously mentioned technologies of the LAA / LWA families, and Wi-Fi Calling, and roaming between cellular networks and Wi-Fi networks with automatic network selection. From the point of view of the Wi-Fi data transfer method, both 4G and 5G are very close, since the standards of the 802.11 family use the OFDM modulation method, and in modern versions – OFDMA, which is almost similar to that used in 4 / 5G cellular networks. There are many features and differences, but fundamentally the methods and available modulation and encoding levels of Wi-Fi and 4 / 5G are close (much closer than 3G and 4G to each other), which means that the spectral efficiency in a single channel is similar.
It must be emphasized that Wi-Fi is developing in parallel with cellular networks, but always ahead of cellular standards in terms of supported data rates over short distances. Over the past 10 years, as in mobile communications, there has been one big change in the generation of Wi-Fi standards. Modern 802.11ac has virtually replaced 802.11n (adopted in September 2009) from the product lines of equipment manufacturers. But if in mobile communications the replacement of standards is accompanied by significant and expensive infrastructure transformations due to limited or absent backward compatibility between generations of communications, then Wi-Fi is developing much more smoothly. 802.11ac is fully backward compatible with 802.11n and does not require major conversions to use it on existing networks. Since 802. 11ac is the de facto standard for today, it is logical to compare its parameters with the parameters of 4G networks available now. IEEE uses the approach of introducing standards “in waves” (however, like 3GPP) and 802.11ac has already passed the first wave stage (Wave 1) and is now at the Wave 2 stage. The standard provides for the use of Multi User MIMO (which was previously not the case in Wi-Fi was), and the peak speed of the physical channel (PHY rate) available at this stage is 2.34 Gbps using three spatial streams and a frequency band of 160 MHz (four streams can theoretically be used). The real peak peak data rate at this channel speed can be around 1.5 Gbps. 802.11ac Wave 1 offered channel / real speeds up to 1.3 / 0.8 Gbps, and the “old man” 802.11n in the 40 MHz band up to 450/300 Mbps with three streams. The full implementation of the IEEE 802.11ac specification expected in the near future will allow using up to eight spatial streams, receiving a physical channel of up to 6.77 Gbps and achievable peak data rates of up to 4.5 Gbps. In existing high-quality Wi-Fi networks (there are such ones), one can observe peak speeds of 100-150 Mbps when using mobile devices and higher than 200 Mbps when using modern laptops, even on the equipment of the latest versions of the outdated 802.11n standard. Replacing 802.11ac, the new 802.11ax standard (the first approved version is expected in 2019) will add about 40% of the spectral efficiency in a single channel and a fourfold increase in the overall efficiency of using the available frequency band. There is also the standard 802.11ad, which, like the millimeter “part” of 5G, Designed for high-speed communications at ultra-high frequencies (in this case, 60 GHz). This standard defines a peak channel bandwidth of 7 Gbps and supports bimforming. Unlike the millimeter portion of 5G, for 802.11ad there are already a number of mass-produced chipsets for creating subscriber devices. It is being replaced by the new 802.11ay standard, with theoretical peak PHY rates of up to 44 Gbps in one stream, which will add to the millimeter Wi-Fi Multi User MIMO with support for four streams (that is, theoretical physical bandwidth when using four streams and full bandwidth frequencies up to 176 Gbps), aggregation of channels, and significantly increase the working distance between the client device and the access point (up to hundreds of meters). Finally, to complete the 5G analogy, I’ll mention another new 802 standard. 11ah (which also has the official name Wi-Fi HaLow, which for some reason is pronounced “HayLow”), which describes the connection for IoT in the 900 MHz band. Moreover, in this standard, as in 5G, everything is in order with delays and power consumption. It is clearly seen that the ideology of the development of IEEE standards is close to 3GPP andThe three types of networks described above are also being formed in the Wi-Fi world.
Looking at these numbers, it is logical to ask a question – why, in fact, it is believed that “5G is faster”? The theoretically achievable maximum data transfer rates in 5G networks and Wi-Fi networks are quite comparable. From a technical point of view, 5G will not be faster than Wi-Fi (in fact, in the new Wi-Fi standards for 5 GHz, peak speeds can be higher than in 5G standard ranges, depending on the available frequency resource, and in millimeter ranges will be much above). But in fact, this is not so important. The main difference between cellular networks and Wi-Fi is not in data transfer speed, but in usage models. Now we are ready to formulate it more precisely.
Cellular networks are designed for mass service of a huge number of subscribers, and in their design they carry an inherited load of those same basic services. Cellular operators are forced to build their infrastructures in such a way as to provide the most uniform user experience, support for all standards and, if possible, all frequency ranges wherever there is network coverage, in any conditions, in a clean field and in conditions of dense urban development, in buildings and outdoors in the air. 5G, by the way, is for the first time trying to systematically move away from this ideology, to rethink it architecturally, offering to build networks of the type that is required (recall three types) exactly where they are in demand.
To this day, Wi-Fi was originally a technology built around only one basic service — data transmission — and focused almost exclusively on areas where there are compactly many relatively inactive subscribers, mainly indoors. At the same time, the set of additional services for Wi-Fi is very different from cellular networks, largely due to the lack of the need for an agreement and the availability of a SIM card. Many of them are available only in such networks: display of advertising when connected, hyperlocal advertising and analytics, short-term paid access for tourists with instant activation. In addition, due to the neutrality of Wi-Fi in relation to mobile networks, traffic offloading, Wi-Fi Calling and international roaming are possible for subscribers of all mobile operators and any Wi-Fi operators.
Typical mass Wi-Fi equipment that meets the standards has significant restrictions on the radiation power and is designed to serve subscribers located at a short distance. It’s easy to see that Wi-Fi is by its nature a niche technology. Due to this, Wi-Fi from the point of view of architecture is much simpler than cellular networks. The most significant simplification is the lack of a single centralized core network in the Wi-Fi ideology, which in the case of cellular communications is not only necessarily present, but also very complex. Each Wi-Fi segment can be built independently, using solutions for processing and routing traffic “in place” and at the same time be controlled centrally by one operator. As a communication environment that provides network unity of such a system, the Internet is perfectly suitable. Another difference is that the ranges in which Wi-Fi operates either do not require licenses and permissions, or have a significantly simplified licensing procedure and lower cost of a frequency resource, compared to frequencies for cellular communications. Due to this Wi-Fi network is much cheaper per unit per subscriber in the coverage area. No matter how the cellular technology changes, the fundamental difference between it and Wi-Fi remains precisely the unit cost of the infrastructure, which allows serving a certain number of subscribers with a given level of service in a given area. Due to this Wi-Fi network is much cheaper per unit per subscriber in the coverage area. No matter how the cellular technology changes, the fundamental difference between it and Wi-Fi remains precisely the unit cost of the infrastructure, which allows serving a certain number of subscribers with a given level of service in a given area. Due to this Wi-Fi network is much cheaper per unit per subscriber in the coverage area. No matter how the cellular technology changes, the fundamental difference between it and Wi-Fi remains precisely the unit cost of the infrastructure, which allows serving a certain number of subscribers with a given level of service in a given area.Wi-Fi is always cheaper.
On the other hand, if you try to build solutions using Wi-Fi to create continuous coverage, service a large number of subscribers outdoors with a single level of service and centralized management of the subscriber base, the result will be worse than in the case of cellular networks, the economic efficiency and quality of which Outperform Wi-Fi far beyond buildings. It should also be remembered that Wi-Fi frequencies are weaker protected than cellular frequencies, and the likelihood of interference in them is much higher. This is not very important in rooms where the situation is usually under the control of the owner, but creates big problems outside the buildings.
Peace as an alternative to war
Cellular operators are worried about the presence of public Wi-Fi networks not at all because their level of quality, usability and security is lower than that of cellular communications, but because they are free. Since mobile operators have never learned to earn seriously on anything other than traffic, the availability of a free, albeit less qualitative alternative to their networks is unacceptable to them. The market has long been offering an alternative to the enmity between cellular communications and Wi-Fi, which consists in downloading traffic of cellular subscribers to the Wi-Fi network (Wi-Fi Offload) in an automatic, transparent mode for the user. The subscriber may not even know through which network his traffic is currently running, since all services (voice communication, data transfer and all types of messaging services) work without any differences. There are many types and technologies of Wi-Fi Offload (for example, Now Wi-Fi Calling is actively developing, which, in fact, belongs to the Offload category), as well as advanced methods of cooperation and coordination of cellular and Wi-Fi networks (some of which are mentioned above in the text), and increasingly cellular and Wi-Fi operators in they are used all over the world. With the advent of modern and high-quality segments of Wi-Fi networks, they become a natural alternative to building or expanding your own infrastructure with increasing traffic or changing generations of the network, or they can limit investment by creating smaller cellular networks.
To build a high-quality Wi-Fi network in an area where there are many subscribers, you need to invest substantial funds (which, although much lower than the corresponding costs of mobile operators, are also quite material). To invest, you need to have a business case. That is, be able to make money on this network. But practically no one can make money on public free Wi-Fi networks. As a result, public Wi-Fi networks for the most part are built with a direct customer and external financing to solve any problems (convenience for visitors, safety, etc.), except for commercial ones. So, such networks are designed to minimize all costs while maintaining the minimum acceptable quality and do not take into account the needs of mobile operators. The experience accumulated over time using such “cheap” networks, in turn, led to the formation of a stereotype of low Wi-Fi quality as technology. In fact, with proper use and quality design, construction and operation, Wi-Fi can provide a user experience no worse than 4G or 5G, but for less money and only where it is advisable to use it. The experience accumulated over time using such “cheap” networks, in turn, led to the formation of a stereotype of low Wi-Fi quality as technology. In fact, with proper use and quality design, construction and operation, Wi-Fi can provide a user experience no worse than 4G or 5G, but for less money and only where it is advisable to use it. The experience accumulated over time using such “cheap” networks, in turn, led to the formation of a stereotype of low Wi-Fi quality as technology.
WiFi Calling is a solution that allows you to make voice and video calls, as well as exchange text messages over the mobile operator’s core network through a connection to any Wi-Fi guest wifi solutions network. In fact, it solves the problem of poor-quality voice service or its complete absence in the premises without the need for the development of a mobile network in individual buildings. All that is needed is the support of this technology by the networks of the mobile operator and the subscriber device in which the corresponding function is implemented (“flashed” in the smartphone at the system level).
Technologically, WiFi Calling (or Voice-over-Wi-Fi) is a continuation of the Voice-over-LTE service (transmission of voice data over LTE networks), which is based on voice over IP protocol. The fundamental difference between wifi6 wireless solutions WiFi Calling and existing IP-telephony services (Skype or many applications, such as WhatsApp, Viber, Facebook Messenger, etc.) is that the call is made through the core network of a mobile operator and is an ordinary telephone call from a subscriber’s mobile number.
Currently, Wi-Fi Calling is mainly used to improve the quality of voice coverage inside buildings, where for some reason the quality of cellular communication is insufficient and the use of VoLTE is impossible. And “white spots” in the coating can be present both in suburban homes, away from base stations, and in densely populated areas, for example, in buildings outdoor wifi solutions constructed using energy-saving materials, which significantly impede the penetration of a cellular signal. In the absence of sufficient bandwidth, video calls can only be made through a Wi-Fi network (even if voice connections are made in LTE). In these cases, Wi-Fi Calling technology can complement VoLTE, which gives operators the opportunity to launch voice and video services based on IMS even at an early stage of LTE network construction. This will provide a better user experience compared to CSFB. youtube gerçek abone satın al
Convenience for the subscriber
The main advantage of Wi-Fi Calling for subscribers is, first of all, the ability to use voice communication services from their smartphone in case of poor coverage of the mobile network or its absence. Being in a cafe located in the basement, you will no longer need to go outside in order to catch a signal, or download special applications – the connection can be established through a wifi solution Wi-Fi router, which today is almost everywhere. The same applies to suburban homes with poor mobile coverage, and densely populated urban areas, where the indoor signal often leaves much to be desired, while the number of Wi-Fi routers rolls over.
A smartphone with Wi-Fi Calling installed automatically connects to an available Wi-Fi network at a time when the mobile signal becomes too weak to make a call or disappears completely.
Another advantage of Wi-Fi Calling for a subscriber is the ability to significantly reduce the cost of voice communications, including roaming for calls from abroad to the home operator’s network. Firstly, operators do not charge additional voice communications over IP protocol. Secondly, since voice over Wi-Fi is transmitted over the Internet, the call is not tied to the geographic location of the caller. hotel wifi solution Calls to numbers on your home network from abroad will remain free. At the same time, calls to the networks of international operators are charged as usual. Thus, while on a business trip or on vacation abroad, in a hotel with Wi-Fi, it is possible to make and receive calls as if you were in your home region.
Since Wi-Fi calling connections are made through the public Internet, subscribers can access their carrier’s network from anywhere in the world. In addition, users are relieved of the need to install additional applications when traveling outside the home network, and the process of using a subscriber device is no different from the usual one.
Benefits for operators
Wi-Fi Calling helps to reduce the churn of subscribers by improving the quality of voice and video coverage inside the building, where, as a rule, there are guest-wifi solutions Wi-Fi access points. The technology of voice over Wi-Fi networks can be a decisive argument for the subscriber when choosing an operator when there is no mobile coverage in the apartment or house, or the signal is weak, the network is congested, etc.
it’s much more profitable for operators to reuse a huge amount of Wi-Fi networks already available in their Internet access points, including home routers of their subscribers, rather than, for example, invest in stimulating the development of femtocells. Given that the functionality to support Wi-Fi Calling services was originally integrated into smartphones by the manufacturer, operators will not need to spend additional funds on supporting and developing individual voice applications.
The introduction of Wi-Fi telephony also opens up new opportunities for operators in the field of convergence of mobile and fixed communications (FMC). For example, this service gives mobile operators the opportunity to take the place of fixed ones when it comes to customers from the category of small companies that own fiber and their own access point in their office. Thanks to cloud managed wifi solutions WiFi telephony, office employees will be able to maintain their fixed numbers by replacing landlines with smartphones that support Wi-Fi Calling and continue to use them outside the office. In addition, the possible integration between different subscriber devices (mobile and landline phones, tablets and STB consoles) of all members of the same family can also help reduce customer churn.
Together with the opportunities that WiFi Calling offers both for subscribers and operators, the new technology poses a number of difficult tasks for communication companies and equipment manufacturers. The main one is the lack of the ability to switch between 2G / 3G networks and Wi-Fi. The possibility of a seamless transition is currently implemented only for the LTE network, as Both technologies are based on the IMS core. Therefore, outside the range of a Wi-Fi router, if there is LTE coverage, the conversation will not end. “Packet data transmission removes the question of which network is used – Wi-Fi or cellular, because, theoretically, packets are transmitted by that route and using the technology that is currently optimal for the user experience.
Another difficulty for operators whose task is to provide quality voice services is the ability to predict and control the quality of Wi-Fi networks. The operator is not related to the access point set by the user, and the quality of voice services that he provides will depend on the operation of the Wi-Fi network. Difficulties can be caused by interference from a neighboring access point, a high network load or a large range of the router. In addition, modern Wi-Fi technologies provide the transfer of large amounts of data, however, the quality of voice transmission depends not so much on the channel width as on the reliability and continuity of packet transmission from the subscriber device to the access point.
Another aspect that also requires a technological solution is calls to emergency services via Wi-Fi Calling, since voice transmission over the Internet does not allow receiving data about the location of the subscriber.
Wi-Fi Calling in the World
There are still few examples of Wi-Fi Calling implementation – the full-fledged provision of this service is carried out in the USA by Sprint and T-Mobile operators, as well as by the British operator EE. On the way are American AT&T and Verizon, British Vodafone, Singaporean Singtel and other companies that have already announced plans to implement Wi-Fi Calling.
Different operators use the technology and provide the service in different ways. Subscribers of American operators can use Wi-Fi Calling, located anywhere in the world, while EE allows its customers to make calls via Wi-Fi-networks, only located in the UK. Operators and the prospects for new technology are evaluated differently. For example, Wi-Fi Calling has been available to EE subscribers since April this year, while VoLTE launch on the operator’s networks will be possible only by the end of summer. The leadership of the American AT&T last fall, in turn, announced that the company was in no hurry with the introduction of Wi-Fi Calling, considering this technology, first of all, to expand the capabilities of LTE networks in addition to VoLTE.
As for subscriber devices that support Wi-Fi Calling, their number is growing rapidly. If more recently they were limited to several models of smartphones, today they are offered by most of the main manufacturers: Samsung, Apple, LG, Alcatel, Nokia, Sony, ZTE, Microsoft.

It allows best in quality to the networks of large corporations. The industry’s leading 802.11ax access point (Wi-Fi 6), which offers the most advanced solutions in the field of wireless communications. This revolutionary 11ax access point is interesting from all sides. Here, both physical antenna rebuilding, OFDMA support — orthogonal frequency division multiple access, and information multiplexing due to QAM 1024 modulation support, which allows increasing the number of bits of transmitted information per 1 Hz of the frequency range and marking packets in channels. Plus, configuration flexibility and high data rates:
– work in the most popular configurations; – support network upgrade without significant restructuring; – meeting the current and expected needs of devices and applications; – backward compatibility with outdated Wi-Fi standards; – uplink and downlink MU-MIMO channels, which ensures optimum signal and reception reliability; – restoration of the capacity and coverage of the 2.4 GHz and 5 GHz frequency bands.
In addition, it supports management at the organization level, including mass configuration of access points, which allows businesses to immediately deploy it in existing switching infrastructures without harming their budgets or resources.
In real conditions, wireless networks hardly cope with the tasks, but the main reason is not that the existing standards do not have enough transmission speed. It’s just that there are too many devices – in practice it’s not possible to achieve theoretical indicators because of the forced wait until the transmission medium is released, the mutual influence of nearby access points, etc. And over time, the problem is aggravated. Therefore, when developing the next version of the standard WiFi Alliance has paid more attention to improving the efficiency of the wireless network.

The aim was to have access points not attached to flexible furniture or objects. The need was not to install it on custom made poles that could be placed on the beach but rather have it attached to permanent objects like a tree or a coffee hut on the beach.
Another challenge was to place the outdoor access points in an optimum location in order to receive excellent WiFi keeping in mind that the existing infrastructure wasn’t there. A question that raised up from EZELINK’s IT team was how do we design the outdoor access point in a way that the configuration of too many guests won’t slow down the internet connection? They had to design something that would not e ect the power thus usability of the WiFi for the users.
The technical team did many site surveys, on a huge (3 kms) stretched outdoor space. They started first with deploying 5 access points on top of the huts but after a consultation with the Management of Jumeirah they decided that this could cause safety problems in the future. The solution was to find the optimum locations. We designed the infrastructure in such a way that the loss of power connectivity is as minimum as possible. EZELINK created a construction that on peak points the system will remain the same. By keeping 2 different ways: the ordering system would not effect the usability of the WiFi for the users.
The Jumeirah group was keen with EZELINK’s ideas about the location of the numerous access points. Several outdoor access points EZE AC1750AO are now installed amongst many discreet locations across the resort. By having this outdoor access point installed on the beach of Madinat Jumeirah it gives the client more flexibility to use their mobiles, tablets or laptops and it improves numerous benefits for their clients experience.

Standard “footfall counting” guest wifi solutions solutions never meets the need because they only count people. They can’t tell how long each customer stays, or whether the customer has visited the store before. It gets messed up when you move around, especially the children and the counter goes on ticking, providing inaccurate info. And customers’ own descriptions of their shopping habits are not always reliable. EZELINK offers a solution which understand customers real behavior, whenever someone arrives at the mall, where they go, how long they stay in each area, and which stores they actually enter.
The EZELINK wireless network and EZELINK EZESMART MONETIZATION solution can track upto 50,000 mobile devices at the same time. Location is accurate in common areas such as corridors and food courts. EZELINK is currently working to fine-tune location accuracy to show when someone actually enters a store, as opposed to lingering near the door. Pinpointing location is exceptionally challenging in retail environments because of the interference from electronic equipment for sale, and from stores’ private wireless LANs.

The Internet is now such an important part of a person’s life that the lack of access to a network in a restaurant or hotel may well be the reason for refusing the services of the respective organizations. Let’s talk about the features of the deployment of WiFi-networks in the building of guest wifi solutions hotels, important parameters, as well as the hardware component.
The fact that every modern hotel should have access to the Internet via WiFi in its assets is not worth mentioning. wifi6 wireless solutions However, the configuration of the premises and number of other requirements and features make this task somewhat specific. It is important to assess the degree of signal propagation, to choose the right equipment, software and at the same time avoid unnecessary costs.
In terms of wireless network deployment, a typical hotel is somewhat more complicated than an office open space or coffee house. Yes, the density of customer connections is not so high here, but the distribution of the signal is affected by walls, furniture, interior elements, pipes and other engineering structures. At the same time, for the result (for providing quality service to the guests), the ratio of signal levels and noise in any place of the hotel room is extremely important. outdoor wifi solutions Therefore, even at the design stage of the network, it is necessary to conduct a full radio survey and radio planning to determine the optimal points of equipment placement. ucuz tiktok takipçi
Within this stage, specialized equipment and software will be involved. Equally important is information about the characteristics of objects located on the signal propagation path (up to the materials used). Usually, interference analysis is performed according to drawings and floor plans. The discrepancy between the actual situation and the plans can lead to critical errors in the results; therefore, it is advisable to supplement theoretical studies with practical measurements.
An example of a radio coverage map of a floor with guest rooms where a radio survey was conducted.
The situation with new hotels is even more complicated. wifi solution Frequently, the customer still requires radio planning results at an early stage in order to design cable infrastructure. But the actual distribution of the signal is significantly influenced by the finishing materials, so that the radio inspection of the concrete box gives practically meaningless results.
In such a
situation, several equipped demo rooms are needed in which a radio survey is
conducted. They are trimmed and furnished in the first place, and then based on
the obtained measurements (extrapolating them to other numbers) the cable
infrastructure of the entire complex is designed.
There are two fundamentally different approaches to the formation of infrastructure for the provision of Internet access services. The first is the refinement of the existing solution in order to improve its characteristics. The second is the introduction of a new hotel wifi solution integrated solution.
Most hotels seek to optimize technological costs, so they choose the first way – redesign with improved coverage and network capacity but retaining (if possible) already purchased equipment. The second way is more in demand with new objects.
In any case, for the organization quality access will need additional equipment. The volume of purchases is calculated based on the expected density of connections. When choosing a new device, it is impossible not to consider the specifics of the hotel “guest” access – both from a technical and aesthetic point of view. A good access point for hotels should be dual-band. The device should provide load balancing, including through the Band Steering function, which allows clients to switch to the 5 GHz band with devices supporting it, freeing the band in the 2.4 GHz band (for devices that do not support the second band).
The new devices for wireless communications for premises (that is, those places where signal propagation is hampered by overlaps, furniture, etc.) provide Beam-forming technology, which changes the conditions of signal transmission depending on the characteristics of the environment. The device determines which direction of the signal loss is greatest, and this task can be solved together with the subscriber device and the access point independently, depending on the standards supported by the client.
It is worth noting the technology that has already become mandatory in networks of the Enterprise: Airtime Fairness level, which provides protection against a “slow client”, which now cannot monopolize access point resources and does not degrade the overall network performance. In addition, the point should fit into the interior of the hotel. Of course, it can also be removed for a false guest-wifi solutions ceiling, but this may affect the range of the signal, therefore it is recommended to keep the devices visible.
Access points designed for installation in rooms are often issued in the form of ordinary sockets, so as not to stand out. Access points for corridors and other premises are available in different buildings, have the function of disabling network indicators. Additionally, they are protected from theft, for example, using Kensington lock. To minimize the number of wires cloud managed wifi solutions suitable for access points, modern devices use PoE (Power over Ethernet). Such factors as ease of setup, features of access to the device via the web interface, etc. are considered in the second place, because it is assumed that the solution needs to be configured once, after which it will function without additional interventions. Although the hotels have their own additional wishes regarding the monitoring and adjustment of the purchased equipment.
If we are not talking about the development of customized solutions that use specific previously purchased equipment, hotels may well use standard projects from large manufacturers. As an example of this approach – the project of building a wireless network in a hotel with 80 rooms based on our standard equipment.

Along with the equipment for providing wireless access, a convenient authorization system is often introduced, since the password typed on the check or written on one of the pages of the folder with the welcome information in the room is a remnant of the past, like a slow connection or permanent communication breaks. Authorization via SMS or a page on social networks gives the hotel some information about the guest, which, when analysed in bulk, allows you to change the parameters of the offer for the target audience. Technologies provide not only image advantages, but also completely monetized marketing data.
you can use mobile phone applications or similar services that are often
provided with IT partners to save on development. Similarly, in partnership
with leading legal OTT services, guests can be offered streaming video as an
alternative to hotel television.
A wireless network with good coverage and stable Internet access opens up a lot of possibilities in front of the hotel. For example, it allows you to use mobile payment terminals at any point, install ATMs or other self-service terminals. In addition, it is possible to introduce IT-tools for business automation through smartphones and tablets for staff, which allows you to simplify the management of individual services – banquet, maid, catering. And large global hotel chains are already testing various forms of mobile applications for the guests themselves, offering tools to meet their needs with minimal contact with the staff, which are available when connecting to the Internet or WiFi of the hotel network, which is especially convenient for guests from other cities or countries .
