多通道多点分配系统(MMDS)是一种新兴的宽带无线接入技术,它具有高带宽和双向数据传输的特点,可提供多种宽带交互式数据及多媒体业务。MMDS以点对多点的广播信号传送方式为电信运营商提供高速率、大容量、点对多点的高可靠性、全双工的宽带接入手段。运用MMDS的目的就是实现用户远端到骨干网的宽带无线接入,进行包括话音、数据、图像的传输,更可作为Internet的宽带接入。
Multichannel Multipoint Distribution System (MMDS) is an emerging broadband wireless access technology featuring high bandwidth and bi-directional data transmission for a wide range of broadband interactive data and multimedia services. MMDS provides high-speed, high-capacity, point-to-multipoint high reliability and full duplex broadband access to telecom operators in a point-to-multipoint broadcast signal transmission mode. The purpose of using MMDS is to achieve broadband wireless access to the backbone network from the user’s end, including voice, data, image transmission, but also as a broadband Internet access.
