摘要
为解决城区复杂无线环境造成的移动宽带网络覆盖和干扰问题,在传统电调天线的基础上,提出了一种下倾角最大达到25°的大下倾天线解决方案。通过天线原理分析,引入增益控制等关键技术解决天线下倾过大时导致的辐射性能变化问题,经实验室性能测试和外场应用,充分证明了该天线能够满足目前城市复杂无线环境的网络覆盖控制和业务质量要求,有效降低了网络干扰,业务性能质量得到显著提升。
In order to solve the urban mobile broadband network coverage and interference problems caused by complex wireless environment,it puts forward a big electrical downtilt antenna solution（ maximum angle of 25°）. Through the principle analysis,the key technology such as gain control is introduced to solve the antenna downtilt large changes in the performance of radiation problem,laboratory performance test and field application,fully demonstrated the antenna can meet the current network coverage control requirement and service quality of the urban complex environment,effectively reduce the interference of the current network,received a significant boost business performance quality.
