基于LMDS的小区宽带无线接入网方案设计

Design plan based on LMDS for wirless broad band access of community

针对目前应用于住宅小区中的几种宽带接入技术的不足及为了解决因接入网宽带不足而出现的网络“瓶颈”问题,介绍了近年来受到国内外电信业务经营者普遍重视的一种新兴的宽带无线接入技术——LMDS。对基于LMDS技术的住宅小区宽带无线接入网络进行了设计。该系统可用频带宽,支持话音、数据、图象等双项通信业务,无须架设线路,具有建设速度快、初期投资小、系统扩展性好、受环境制约小、又能满足住宅用户对快速业务的需求。可以预见,LMDS将逐渐成为用于高速多媒体应用的最佳网络接入方案。

In view of the deficiencies of several kinds of broadband access technologies applied to housing district and in order to solve the pear network‘bottleneck’problem because of insufficient access network bandwidth at present,a kind of the new developing access technology of wireless broadband-----LMDS is introduced,which is paid attention to by domestic and international telecommunication service operators.Design plan based on LMDS for wireless broadband access of the community is carried out,which the bandwidth frequently can be used in this system to support pairs of communication service of the speech,data,vision etc.It needn't erecting the circuit, having fast construction speed,small investment in initial stage,the system expansion is last,limited by environment and can satisfy user's ment demands for fast business.It can be predicted that LMDS will gradually become inserting scheme of best network which the high-speed multimedia uses.
