大功率无线直放站
根据系统制式和功能的不同,大功率射频直放站可以分为很多种.
大功率直放站通常通过施主天线接受来自远处基站的微弱信号,然后将其放大,并传输到信号无法覆盖到的大楼或区域里.同时,手机终端信号也可通过直放站放大,再传送到基站.因此,直放站相当于在直放站和手机之间重新建立起了通畅的通信通道.大功率直放站能在应用在多个场景,如展览中心、地下室、购物商场、办公室、停车场等,改善室内信号覆盖质量.特别是在分布式天线系统中,直放站是至关重要的一部分.室外场景方面,机场、旅游景点、高尔夫球场、隧道、工厂、矿区、村庄等同样适用.与建设新基站相比,大功率直放站是一种更经济实惠的信号覆盖解决方案.
安信通讯作为一个专业的射频直放站制造商和供应商,致力于为全世界提供高质量的信号覆盖方案.
