Operators more urgent to expand indoor and outdoor network coverage

Andria Cassigny Andrea Casini, a vice president for markets and sales in Europe, the Middle East and North Africa in Andrew FX, explains why mobile operators need to expand their indoor and outdoor network coverage more than ever before. Today, about three-fourths of mobile calls are made or received in building houses-a huge change compared to 10 years ago. In fact, the use of fixed-line telephony is declining, with more and more consumers and business users choosing mobile phones as their primary means of communication, even when they are very close to the landline. There is no doubt that it is more convenient to use mobile phones.　　More technologically advanced, full-featured handsets are constantly driving users to turn their mobile devices into tools for storing and accessing information, far exceeding the traditional voice-call use, which includes increasingly popular mobile email applications and internet browsing. Mobile operators must quickly recognize the advantages of planning a network deployment to provide a wider range of services based on the expanding use of indoor mobile phones. As long as the new network is concentrated, the market will stagnate, and the mobile operator will seek a new way of making profits. Many operators expect the launch of the building and professional coverage project to be a new way to gain average income per unit user (ARPU). The recent upsurge in building solutions is driven by the network optimization activities that operators have taken to try to solve problems such as interference, capacity, and blind spots in the areas of the building and the urban areas around the building, especially the high permeability of business users.　　One of the best examples of this situation is the deployment of an Android building system in the Canary Wharf in London. As competition in this field intensifies, mobile operators must take a serious approach to the changing needs of an increasingly liquid society. Along with the development of wireless technology, consumers and business users alike require wider network coverage and lower "downtime" (i.e. where wireless signal access is restricted or not available). The massive increase in 3G data Services has contributed significantly to the traffic of indoor and outdoor wireless networks, while high speed data processing performance is becoming an increasingly important factor.　　Mobile data traffic has soared in recent months as more and more sites are choosing mobile platforms, with more than 25% of British users now using mobile devices to access the Internet, for example. In particular, some companies are ready to provide wireless coverage in their offices because of the increasing number of employees who need wireless coverage and the fact that their offices are located in business locations. Owners of public buildings are also beginning to recognise the benefits of indoor wireless coverage, and owners of airports, malls and large open-air stadiums are more eager to provide wireless Internet access to their users. Companies are demanding a range ofCommunication methods, including e-mail, instant messaging and voice video calls, and so on, to instantly access. It is becoming increasingly difficult to accept that operators offer unreliable services, especially when market competition is becoming more and more intense.　　The competition for wireless coverage has been severely magnified in the dense urban areas, which is why operators need to consider the deployment of advanced building solutions. So what is the solution to this kind of building? What are the most popular programs for operators? Which programs provide the most effective indoor wireless coverage? Pico-Femtocells and Pico-honeycomb (picocells) base stations are one of the alternatives. The ABI survey company predicts that the tiny honeycomb and pico-cellular base stations will rise rapidly as an important part of the initial debut of the Long-term Evolution Network (LTE). Long-term Evolution network to use a higher frequency, and high frequency penetrating structure is not as effective as low frequency, so the small honeycomb and pico honeycomb for the indoor low signal strength provides a very attractive compensation method.　　Although many telecoms equipment manufacturers are actively supporting the development of Pico-honeycomb, the market is limited because the technology is designed primarily for residential and small business environments. However, while many operators have started experimenting with pico-honeycomb technology, other operators have been hesitant because of potential network management difficulties. According to the survey, Pico-cellular technology does not necessarily save operators any capital expenditure or operating costs. If Pico-cellular base stations are sold to customers in retail mode through traditional mobile operator channels, this may result in the deployment of Pico-cellular base stations to be distributed in large areas. However, Pico-cellular base stations need to be centrally deployed to ensure an effective alternative to the Macrocell network, otherwise they become a burden to operators.　　So now the deployment of Pico-cellular base stations has not yet entered the fast lane. Another alternative is a distributed Antenna system (DAS), which works by acquiring a donor-transmitted signal from a macro cell or a relay station, and then propagating the signal by accessing the fiber in the building. The typical components of such systems are coaxial and radiant cables, power splitters, directional couplers, and indoor antennas. A dedicated radio base station connected to a distributed antenna system can enhance the quality of voice service and data service by guaranteeing the specific coverage and capacity, limiting the signal range, preventing signal leakage and interference. This solution, in addition to being able to initiate communications that did not cover the area before, can also mitigate the load on the macro network in overlapping coverage areas.　　Other advantages of distributed antenna systems are that they can either serve an operator or a multiple operator, and it can also apply one or more bands (for example, GSM900, GSM1800, and WCDMA). It is the active distributed antenna system that is driving the current market, according to a recent report by the ABI Survey company. The ABI survey company indicated that the supply of equipment covering the super large buildings would be pushedThe active distributed antenna system is growing at a comprehensive annual growth rate of 28% to 2013 years. According to ABI Research, this is because the active distributed antenna system can achieve maximum cost benefit in super large buildings. However, in less than 500,000 square feet of buildings, passive systems, such as relay stations and passive distributed antenna systems, will be more cost effective.　　However, with the increase of the revenue of data service in the average income of the users of wireless service units, the capacity becomes an equally important related design factor. In the design building wireless system, the network capacity also plays the more and more important role. When the building is small, and the older passive system is installed in the corresponding position, a toolkit, including a relay station, a pico-honeycomb, a pico-honeycomb, active and passive distributed antenna system, is usually chosen as a solution. For operators, in order to obtain the share of revenue from the enterprise market, it is more effective to create distributed antenna system and repeater system in enterprise environment. While operators can be happy to reduce infrastructure costs and win large numbers of corporate customers, companies that lease office space are more likely to expect seamless wireless coverage, so it is unrealistic to expect any building to be limited to one operator. In public buildings, in order to provide enough wireless coverage for all users, it is more important to allow access to multiple carrier environments.　　For this reason, for large companies, mere pico-honeycomb technology is by no means an option worthy of serious consideration. The future of the European building system will be determined by the European building Code, which will dictate the mode of pre-installed wireless infrastructure approved by the operator, and its implementation will inevitably depend on who finances it. It remains to be seen whether the owners or operators of the buildings are ultimately responsible for most of the funding for wireless infrastructure deployments, but what we do know is that operators are eager to remain in control.　　One solution is for carriers to share costs; This approach is already on the macro level and is likely to trickle down to various project levels. It is becoming clearer that in complex buildings, such as large office buildings, airports, shopping malls and open-air stadiums, there is a demand for specific coverage and capacity to meet the requirements of high-end consumers, as well as safety requirements. The user's requirements require it to have sufficient communication resources, the most normal condition is mainly the use of micro-base stations and Pico base stations, and passive and/or active distributed antenna system to complement. Sometimes, in some places, especially in the suburbs, return transmissions can be a limiting factor. Another aspect that needs to be taken into account is that typical network planning is two-dimensional, so the third Viterbi of vertical buildings is often omitted. This factor often obscures the visibility of the relationship between potential high traffic and income (return), which is simply overlooked or overlooked. As a result, the network may encounter a large number of traffic congestion and blockingPlug, causing call failure and poor access conditions.　　A key factor in the proper assessment of this risk is to improve the positive customer experience and increase the growth rate of business in today's competitive ecosystems. Andrew can provide the right tools to accurately measure the quality of the network and the amount of traffic lost. Our wireless coverage solutions can be applied to a large number of densely populated urban areas, such as the Canary Wharf in London and the West end of Glasgow, as well as stadiums such as the World Cup stadium in Germany and the Millennium Dome in London. To overcome the limitations of wireless communication in a restricted environment, we have a variety of scenarios to deploy. The solution here can be a simple, typical coverage of the scheme, or by providing additional street-level wireless tiering, from the high-density user area of the macro network to unload urban traffic, so as to achieve the optimal network capacity distribution scheme. From an economic and technical standpoint, these schemes are extremely attractive because of the intrinsic nature of the shared infrastructure that can be used effectively by multiple wireless carriers and service providers.　　While the advantages of cost-sharing are obvious, it is worth mentioning that the technical advantages of sharing the solution, along with the consistent reliability of radio performance, make a significant contribution to reducing interference and maximizing capacity and efficiency. Recently, the South African Vodacom Company has opted for the deployment of wireless coverage and wireless capacity solutions for the South African stadium to be used by the International Football League 2010 FIFA World Cup. Andrew has already deployed ion in 5 of the 10 South African stadiums that will be used in the World Cup. (Intelligent optical fiber network) Fiber distributed Antenna system. The South African Confederations Cup has proved how important it is for the audience to share the joy and passion of the game with their distant friends through wireless text, wireless calls and wireless multimedia. With the 2012 London Olympic Games approaching, the indoor communication system of the stadium has become one of the hot spots in everyone's mouth. Organizers of large events now need seamless wireless coverage, at the same time, with the development of technology, now more than a few years ago with the ability to deal with higher capacity, wireless manufacturers in order to stay ahead in the competition, now need to optimize their services, in the visual impact of the least, at competitive prices, to provide multiple operators, Top-level capacity services.
