中文摘要:
      介绍了应急场景下蜂窝基站无线桥接应用的需求,从应急场景信号覆盖和网络流量两个情况,比较了WiFi网桥、LTE网桥和UHF网桥的技术优劣,针对UHF无线网桥,基于无线信号传播模型,从理论上分析了链路预算与发射功率需求,并对上海地区地面广播电视频谱分布情况进行了分析,指出地面广播电视的空白频谱可以用于应急场景下蜂窝基站的UHF桥接。
英文摘要:
      The requirement of wireless bridge application between cellular base stations in emergency scene is introduced. The advantage and disadvantage of WiFi-based bridge, LTE bridge and UHF bridge are compared taking signal coverage and network traffic into account. The link budget and the requirement of transmit power of the UHF bridge is analyzed by using the wireless signal propagation model. It is concluded that the white spectrum of terrestrial broadcasting can be used for UHF bridge between cellular base stations in emergency case.
