宽带无线接入技术有LMDS、MMDS、Wi-Fi、WiMAX、3G等,和有线接入相比,无线接入技术更具备优越性。宽带的无线接入技术具备启动资金少、建设的周期短、提供服务快速、具备很大的灵活性、可根据需求动态分配系统资源、系统维护成本低等优势。近年来,随着现代信息技术的发展、市场需求的增长和通信行业的竞争目标转移,促进了宽带无线接入技术在中国的兴起,市场化的规模迅速扩大;但是从总体上看,我国无线宽带接入技术和国外相比,还是有一定的差距。
Broadband wireless access technology has LMDS, MMDS, Wi-Fi, WiMAX, 3G, etc., compared with wired access, wireless access technology more advantages. Broadband wireless access technology with less start-up capital, short construction period, rapid service provision, great flexibility, dynamic allocation of system resources according to requirements, and low system maintenance cost. In recent years, with the development of modern information technology, the growth of market demand and the shift of competition targets in the telecommunications industry have promoted the rise of broadband wireless access technology in China, and the market has rapidly expanded its scale. However, on the whole, Broadband access technology and compared to foreign countries, there are still some gaps.
