Research And Implementation Of WiFi Technology In Digital Wireless City

With the development strategy of "digital wireless China” continues to advance,the domestic operators bring the construction of digital wireless network into the enterprise development strategy based on the needs of business development,and this strategy also matches the development target of national information construction.Today,China's mobile communications 4G network license has been issued.Due to the specificity of WiFi network technology,there are differences between WiFi network and GPRS / EDGE and TD-LTE network.In order to meet the current needs of data access in a variety of scenarios,WiFi and GPRS / EDGE,TD-LTE network will coexist for a long time,which is the organic component of the operator's data carrier network.Therefore,the construction of urban digital wireless network is not only urgent needs,but also very significant for China's three major mobile operators.In China,the national policy will affect the construction strategies and methods of "digital wireless city" by domestic operators.Therefore,there are certain differences between foreign market-oriented operating model and domestic operating model,and the construction experience in the "digital wireless City” offered by foreign operators makes little sense for domestic operators.Up to now,people's overall understanding of the digital wireless city is still inadequate.They think it is only constructing a digital wireless network.Moreover,there are differences in the guiding ideology and promotion intensity of digital wireless city construction by local governments.The enthusiasm and intensity devoted by operators in the digital wireless city are also different,and the domestic construction in digital wireless city is very different.This paper is based on the case of mobile operator's WiFi network construction in medium-sized cities of western China,studying the realization of digital wireless city based on WiFi technology.The research results are intended to provide useful guidance and reference for the construction of "digital wireless city".The main research contents are as follows:1.Study the features of WiFi technology and current technical standards,and discuss WiFi key technology,and get a feasible conclusion in constructing "digital wireless city" with WiFi technology.2.Study the planning and design scheme of digital wireless city based on WiFi technology,and expound the planning principles,the type of covered scene,network architecture and solutions for coverage that suitable for the construction of digital wireless city in large and medium-sized cities.The planning methods and the main network indicators of network coverage,capacity and frequency provide technical support for the construction of digital wireless city.3.Study the digital wireless construction scheme based on WiFi technology,discuss the construction model of digital wireless-covered project in various domestic large and medium-sized cities,and provide useful reference for the network construction of digital wireless city.4.Study the main application of digital wireless city,discuss the convenience for people's daily work and life with the construction of digital wireless city,and further demonstrate the significance of digital wireless city construction.5.Conclude the preliminary achievements in digital wireless city construction,and demonstrate that the construction of digital wireless city is the only way leading to Wisdom city with the development of current WiFi technology.
