WCDMA Network Wireless Environment Evaluation Method And Application

With the gradual opening of the telecommunications market, telecom operators and more intense competition among the network operators to provide customers with quality service quality as the basis for increasing telecom operators attention. The wireless environment is a key part of user access, but also a top priority for operators. With the continued construction of WCDMA networks, how to scientifically and comprehensively grasp the wireless environment into telecom operators placed in front of a big problem. Although China Unicom already has a wealth of GSM/GPRS wireless environment management experience, has established a certain amount of wireless environment assessment methods, but the environmental impact assessment for the WCDMA wireless system has not been completely established.This article describes the WCDMA system architecture, channel and key technologies related to preparations for knowledge, analysis of the impact of the main indicators WCDMA wireless environment factors. WCDMA technology system for the wireless environment assessment model, through the DT data and MR data comprehensive analysis, given the weak coverage, over-covered plot, pilot pollution, from top to bottom-line coverage unbalanced district of assessments. WCDMA networks with emerging wireless environment related issues and put forward a number of effective solutions, practical case studies shows that our proposal is reasonable and feasible.
