Research Based On GSM Dual-band Wireless Network Optimization

Different stages of the development of GSM networks, the main contradiction facing different. In the initial stage of network construction, the main problem facing the cover; With the current rapid growth of data services, network load increases, the interference within the network more and more problems. In many cities, shrinking space station, overlapping coverage increased significantly, and because of the high-carrier configuration, making the same dramatic increase in the probability of adjacent channel interference, background noise was uplifting, 900M network quality and capacity can not meet the load demand has been significant.In order to increase network capacity and call quality, or frequency in a number of traffic strain on the resources the larger cities have set up a dual-band network GSM900/1800 sizes. GSM900/1800 dual-band network is the network capacity and coverage needs of both the result of merging.This topic describes in practical work on the dual-band network of research and discovery from network problems and solutions: In GSM900/1800 dual network mobile phone users are constantly changing conditions, all the mobile users form changing communications environment, and communication networks is to protect this ever-changing communications environment, providing voice quality The minimum requirements to allow users to maintain the call. On the other hand, in the premise of ensuring network quality should make maximum use of existing network resources for more users. In the dual-band network, under the premise of guaranteeing quality, high resource utilization (such as telephone traffic per line) are likely to increase the network capacity. Therefore, GSM900/1800 dual focus on network optimization to improve network quality and network resources efficiently.This topic describes In the dual-band networking and wireless communication GSM900/1800 on the basis of characteristics, focusing on network optimization in the dual-band absorption in traffic strategy, traffic equilibrium strategy, different location area traffic control strategies through the wireless parameter setting (cell selection Parameter cell reselection parameters, switching parameters, etc.) to achieve the ZTE device. Part of the issue to the county of Baoding frequency optimization, for example, an overview of the engineering parameters and the configuration of radio parameters, and the actual optimization optimization strategy in the dual-band network, network problems, deal with ideas and solutions. Site optimization data to prove the superiority of GSM900/1800 dual networking, dual-band network a better ability to enhance the network coverage, voice quality while ensuring the quality of the premise of absorbing more traffic, thereby reducing the GSM network, then Service burden and improve the user perception, is worth promoting the networking and optimization experience.
