無線通信室內(nèi)覆蓋設(shè)計(jì)

摘要


3G它的全稱是3rd Generation，中文含義就是指第三代數(shù)字通信。3G是向未來個(gè)人通信演進(jìn)的一個(gè)重要發(fā)展階段，具有里程碑和劃時(shí)代的意義。1995年問世的第一代模擬制式手機(jī)（1G）只能進(jìn)行語音通話；1996到1997年出現(xiàn)的第二代GSM、TDMA等數(shù)字制式手機(jī)（2G）便增加了接收數(shù)據(jù)的功能，如接受電子郵件或網(wǎng)頁；第三代與前兩代的主要區(qū)別是在傳輸聲音和數(shù)據(jù)的速度上的提升，它能夠在全球范圍內(nèi)更好地實(shí)現(xiàn)無縫漫游，并處理圖像、音樂、視頻流等多種媒體形式，提供包括網(wǎng)頁瀏覽、電話會(huì)議、電子商務(wù)等多種信息服務(wù)，同時(shí)也要考慮與已有第二代系統(tǒng)的良好兼容性。

室內(nèi)覆蓋是針對(duì)室內(nèi)用戶群、用于改善建筑物內(nèi)移動(dòng)通信環(huán)境的一種成功的方案。本文比較詳細(xì)的介紹了室內(nèi)覆蓋的具體環(huán)節(jié)及實(shí)施過程。闡述從理論的設(shè)計(jì)方案到網(wǎng)絡(luò)優(yōu)化工程的竣工。室內(nèi)覆蓋原理是將基站的信號(hào)通過有線方式直接引入到室內(nèi)的每一個(gè)區(qū)域，再通過小型天線將基站信號(hào)發(fā)送出去，從而達(dá)到消除室內(nèi)覆蓋盲區(qū)、抑制干擾的目的，為樓內(nèi)的移動(dòng)通信用戶提供穩(wěn)定、可靠的室內(nèi)信號(hào)，使用戶在室內(nèi)也能享受高質(zhì)量的移動(dòng)通信服務(wù)。 室內(nèi)覆蓋系統(tǒng)的建設(shè)，可以較為全面地改善建筑物內(nèi)的通話質(zhì)量，提高移動(dòng)電話接通率，開辟出高質(zhì)量的室內(nèi)移動(dòng)通信區(qū)域；同時(shí)，使用微蜂窩系統(tǒng)可以分擔(dān)室外宏蜂窩話務(wù)，擴(kuò)大網(wǎng)絡(luò)容量，從整體上提高移動(dòng)網(wǎng)絡(luò)的服務(wù)水平。

ABSTRACT

The full name of  3 G is the 3 rd Generation, which of Chinese is third generation of digital communication. 3G  is an important of developing stage of gradual  progress of personal communication of future and have molestone and epoch-making meaning. first-generation analog mobile phone system (1G) can only be making  voice calls since it came out in 1995 the second generation of GSM, TDMA digital mobile phone standard (2G) increase the function of receiving data,such as receiving  E-mail and web pages. the biggest defference between the third generation and the first two generations is the promotion at the speed of transmitting sound and data. it can at the global level to better achieve seamless roaming, and to deal with images, music, video streaming and other forms of media provided, including web browsing, conference calls, e-commerce and other information services, we must also consider the second-generation system has a good compatibility.

Indoor coverage interior user groups are targeted for improvement in building  mobile communications environment, a successful program. This article describes in more detail the specific aspects of indoor coverage and the implementation process. Explained from a theoretical design of the network optimization project completed.The principle of indoor coverage is that the base station's signal through the cable directly into the interior of each region and then through the small base station antennas to send signals go out, so as to achieve the elimination of interior blind spot coverage, the purpose of interference suppression for the building of mobile communication users to provide a stable, reliable signal of the interior, so that users can enjoy high-quality interior of the mobile communications services. Indoor coverage systems, can provide a more comprehensive manner to improve call quality buildings, enhance the mobile phone through rate and open up the interior high-quality mobile communications region; At the same time, the use of micro-cellular systems can be shared outdoor macrocell traffic, and expand network capacity, improve the overall mobile network service levels.

KEYWORDS: 3G, 2G, indoor coverage, indoor coverage systems
