1、第頁I移動(dòng)通信室內(nèi)分布系統(tǒng)的分析與設(shè)計(jì)移動(dòng)通信室內(nèi)分布系統(tǒng)的分析與設(shè)計(jì)摘要摘要:根據(jù)最新統(tǒng)計(jì),在第三代通信網(wǎng)絡(luò)中大約75%以上的話務(wù)量是發(fā)生在室內(nèi)的,且其增值業(yè)務(wù)也絕大多數(shù)也發(fā)生在室內(nèi)。所以移動(dòng)運(yùn)營商品牌形象將重要體現(xiàn)在3G室內(nèi)覆蓋上面,這也是運(yùn)營商吸引更多用戶的重要因素。從GSM網(wǎng)絡(luò)優(yōu)化理論來看,為了在高層建筑物內(nèi)保證無線信號的連續(xù)覆蓋,建立分布式系統(tǒng)是必要的。本文將主要從室內(nèi)分布系統(tǒng)的技術(shù)指標(biāo),設(shè)計(jì)原則,勘測原則,設(shè)計(jì)依據(jù)等幾個(gè)方面
2、來系統(tǒng)的介紹室內(nèi)分布系統(tǒng)的設(shè)計(jì)要點(diǎn)和技術(shù)要求。本文主要解決的問題是在復(fù)雜情況下對直放站信源選取上的標(biāo)準(zhǔn)和實(shí)際調(diào)測中的問題的解決。設(shè)計(jì)的依據(jù)和要求主要是參考中國移動(dòng)2007年印發(fā)的《TDSCDMA室內(nèi)覆蓋工程技術(shù)方案指導(dǎo)原則》以及中國聯(lián)通2008年《WCDMA室內(nèi)覆蓋》的施工設(shè)計(jì)要求來完成的。以六安市白云商廈為實(shí)施對象進(jìn)行的設(shè)計(jì)。這次設(shè)計(jì)中主要考慮覆蓋的形式,電磁環(huán)境的測量,技術(shù)方案的實(shí)施,以及對設(shè)計(jì)方案分析話務(wù)量分析,切換掉話分析,下行
3、增益的確定,上行噪聲分析,上下行平衡分析等有關(guān)數(shù)據(jù)的測試和系統(tǒng)的設(shè)定。為以后的類似的設(shè)計(jì)提供了借鑒的模版。關(guān)鍵字關(guān)鍵字:噪聲,功率,增益,直放站第頁III目錄前言...........................................................................................................................................
