3G多样性业务环境下无线覆盖半径的估算

Diversity of the Business Environment of 3G Wireless Coverage Radius Estimates

3G网络是支持高速率数据及综合多媒体等多样性业务的系统。覆盖、容量和服务质量三者是交织在一起的,因此,在进行无线覆盖规划设计时,必须同时考虑容量、不同业务以及不同服务质量的要求,才能达到设计目标。本文对3G多样性业务环境下无线覆盖半径的估算进行了讨论。介绍了链路预算、无线传播模型及多样性业务对覆盖半径的影响等几个重要问题。特别是对负荷因子、干扰余量进行了分析,给出了不同小区负荷情况的上行链路预算举例。论文对3G无线覆盖规划设计具有一定的指导意义。

3G network is a system which supports the high speed data and synthesizes multimedia and so on.The cover,the capacity and the grade of service are interweaves.Therefore,we must simultaneously consider the capacity,the different service as well as the different grade of service s request to achieve the project objective.This article discusses the estimate of wireless covering radius under 3G multiple service environment we introduce the interaction of the link budget,the wireless dissemination model and the ...
