Yichun Telecom Cdma Network Pilot Pollution Research And Analysis

This article from the CDMA network to solve the common pilot pollution problems, we should solve the high-level pilot explained the importance of pollution problems, through actual case on which different frequency solutions to the key description.In recent years, as the city development and construction, the increasing number of high-rise building construction, urban high-rise buildings gradually outstanding pilot pollution, seriously affecting the user's perception in the room calls, restricting the high-end users in the market. This article highlights the high level of pilot pollution in the four Common Solutions, through a concrete case on which the different frequency solutions are analyzed in detail. Different frequency to resolve the basic principles of the program is through the introduction of the indoor-specific frequency and use of pseudo-pilot, the mobile phone into the room, through the pseudo-pilot to switch to the room dedicated auxiliary frequency point, so both indoors and where mobile phones, can presence and frequency from a dedicated point of call; the same time, as the frequency is room dedicated external network of no such frequency, so the window can also get the satisfaction of the former to the Ec / Io, ensure call quality. Finally, in future CDMA network planning and engineering design, attention to pilot the impact of pollution on the network to a minimum. In the project to take all measures to control the effective coverage of base stations, network optimization that reducing the complexity and workload, improve the quality of the whole network communication play a multiplier effect.
