【正文】 無線網(wǎng)絡(luò)規(guī)劃流程 網(wǎng)絡(luò)規(guī)劃的流程如圖 11 所示。課題提供的設(shè)計(jì)是GSM 擴(kuò)容工程實(shí)施的依據(jù)，對(duì)工程實(shí)施過程進(jìn)行良好的監(jiān)控，對(duì)工程實(shí)施過程中出現(xiàn)的問題及時(shí)的進(jìn)行優(yōu)化的處理，同時(shí)也伴隨著工程實(shí)施對(duì)網(wǎng)絡(luò)規(guī)劃設(shè)計(jì)方案進(jìn)行改進(jìn)，以使得 GSM 網(wǎng)絡(luò)有更大的網(wǎng)絡(luò)容量和更好的網(wǎng)絡(luò)質(zhì)量，讓 GSM 網(wǎng)絡(luò)更加有利于多制式、多系統(tǒng)的共存和發(fā)展。它是一項(xiàng)系統(tǒng)工程，從無線傳播理論的研究到天線設(shè)備指標(biāo)分析，從網(wǎng)絡(luò)能力預(yù)測(cè)到工程詳細(xì)設(shè)計(jì)，從網(wǎng)絡(luò)性能測(cè)試到系統(tǒng)參數(shù)調(diào)整優(yōu)化，貫穿了整個(gè)網(wǎng)絡(luò)建設(shè)的全部過程 [1]。無線網(wǎng)絡(luò)規(guī)劃的目標(biāo)在于充分利用頻譜資源，周密規(guī)劃，在滿足業(yè)務(wù)需求的前提下，用最小的分期動(dòng)態(tài)投入實(shí)現(xiàn)最大的技術(shù)經(jīng)濟(jì)效益。以上問題都需要通過網(wǎng)絡(luò)規(guī)劃來解決，通過網(wǎng)絡(luò)規(guī)劃可以使 GSM 網(wǎng)絡(luò)在覆蓋、容量、質(zhì)量、成本等方面實(shí)現(xiàn)良好的平衡。長(zhǎng)春理工大學(xué)光電信息學(xué)院畢業(yè)設(shè)計(jì) ( 論文 )1目 錄第一章 緒論
