摘 要：
    WCDMA作為3G三大標(biāo)準(zhǔn)之一，有完全不同于GSM的技術(shù)特點(diǎn)，其無線網(wǎng)絡(luò)規(guī)劃的原理和方法都發(fā)生了變化。WCDMA系統(tǒng)是自干擾、軟覆蓋、軟容量的，這決定了其網(wǎng)絡(luò)規(guī)劃的復(fù)雜性和綜合性，要求網(wǎng)絡(luò)規(guī)劃工程師必須采用網(wǎng)絡(luò)規(guī)劃工具對各個方面的技術(shù)細(xì)節(jié)進(jìn)行綜合全面的分析，才能實(shí)現(xiàn)網(wǎng)絡(luò)規(guī)劃的成功。     
    本文以某市區(qū)為例，探討WCDMA網(wǎng)絡(luò)中純語音業(yè)務(wù)、語音及數(shù)據(jù)混合業(yè)務(wù)的無線網(wǎng)絡(luò)覆蓋規(guī)劃方法及流程，做一些容量、覆蓋及質(zhì)量規(guī)劃并根據(jù)規(guī)劃需求和網(wǎng)絡(luò)特性，設(shè)定工程參數(shù)和無線資源參數(shù)，并在滿足一定信號覆蓋、系統(tǒng)容量和業(yè)務(wù)質(zhì)量要求的前提下，用最合理的方法使網(wǎng)絡(luò)的工程成本最低。
    該無線網(wǎng)絡(luò)規(guī)劃包括預(yù)規(guī)劃和詳細(xì)規(guī)劃，其中預(yù)規(guī)劃包括容量規(guī)劃、站數(shù)估算等；詳細(xì)規(guī)劃包括軟件仿真等。

WCDMA network planning and design
Abstract：
     Being one of 3G standard, WCDMA has great different technical specialty from GSM., so principle and method of WCDMA radio network planning have changed. The self-interferenc, soft coverage, soft capacity of WCDMA system are deeply define the Complexity and synthetecallity of WCDMA network planning. This demand that the network planning engineers has to all-around analyse the technical details of planning by usage of network planner. Hence, success of network planning can be attached.
    This thesis which shows the example for a city，discussesthe methods of network planning for the speech and data services in WCDMA networks .It plans the capability, covering and quality and sets the radio resource parameters according to the planning. It makes the network cost the least based on fulfilling the requirements of certain signal covering, system capability and service quality.
    The radio network planning includes the pre-planning and particular planning. The pre-planning includes capability planning and station number estimation etc. The particular planning includes software simulation etc.
