Application Of MDAS System To GSM Network Signal In Residential Area

The current GSM mobile network is still the most commonly used of the second-generation digital cellular mobile communication network, which supports the largest wireless communications user group in the world, but with the increase of users, the rapid completion of the high-rise, the increase of building density, our wireless environment and wireless network quality withstand the growing challenges, the intensive areas such as residential areas, high-rise office buildings has become the hot complaint areas of mobile phone users, low signal level, poor call quality, slow access become important reason customers complain and from loss. Communication operators and equipment manufacturers try a variety of ways to solve this problem, including the re-planning of base station construction to increase the coverage density, building micro-cellular base station to extend coverage, to supplement coverage through GRRU light pull far way. Found in the actual network construction, however, with the increase of the size of the residential area and the floor height restrictions, the locations where we can construct the outdoor base station to solve problems become fewer and fewer, the solution of micro cellular is ineffective due to the housing structure, and some residents consider that the wireless signal radiation will affect the health. So building signal antennas in buildings and residential areas is also becoming more and more difficult.This article focuses on the programs, feasibility and ability which solve the network weak coverage and network low quality problems in the current buildings and residential areas in day-to-day work of network optimization using MDAS system technology based on the Ethernet cable of GSM coverage. Papers do the investigation and research on the current coverage of wireless micro-cellular network for the problems of traditional coverage system, to fully understand the difficult problems of construction of wireless network coverage in the residential areas and commercial buildings. Understand the wired broadband and the construction method and technology of GSM micro-cellular network, and analyze and research the MDAS technology which is based on the GSM network whose frequency band is limited, sort out the MDAS system’s equipment, networking, performance, critical technology, propose some solutions in commercial buildings, residential areas and other scenes. Construct network and test network with combination of actual residential areas and buildings, study wireless coverage effect, the quality of the wireless network, broadband network performance indicators as well as the feasibility of practical application.Finally, according to the technical characteristics of the MDAS, sum up the advantages of its current coverage of GSM time division single network and analyze the MDAS technology application promotion feasibility.
