宽带固定无线接入技术具有以下几点优势:* 频率复用度高,系统容量大。在3.5GHz频段的3.5MHz带宽内,采用高效调制技术,可以向用户提供10到20兆的传输速率,而采用多扇区、多基站的频率复用技术,则能使系统的容量达到千兆。* 启动资金较少。不需要进行大量的基础设施建设,初期投入 Broadband fixed wireless access technology has the following advantages: * High frequency reuse, system capacity. In 3.5GHz band 3.5MHz bandwidth, the use of efficient modulation technology to provide users with 10 to 20 trillion transfer rate, and the use of multi-sector, multi-base station frequency multiplexing technology, the system can make the capacity of Gigabit . * Less start-up capital. Do not need a lot of infrastructure construction, initial investment
