5G信号对卫星C波段信号的干扰排查及应对措施

Interference investigation and countermeasures of 5G signal to satellite C-band signal

随着5G试验范围的不断扩大,5G频率会占用C波段频率,并且极易对C波段中标准及扩展波段的下行频率波段信号造成干扰,严重影响日常卫星接收质量,无法有效满足播出安全要求。因此,相关单位需要对波段信号加强排查,并针对干扰问题采取相应的解决措施,有效提升信号传递过程的安全性。文章就5G频段业务及C波段卫星运行状况进行分析,并结合实际测量情况,探讨5G信号对C波段信号干扰问题的有效应对措施。

With the continuous expansion of 5G test range,its frequency will occupy the frequency range of C-band,and it is very easy to cause signal interference to the downlink frequency band signals of standard and extended bands in C-band,and even seriously affect the quality of daily satellite reception,so that the broadcast safety requirements cannot be effectively met.Therefore,it is necessary to strengthen the investigation of band signals,and take corresponding solutions to the interference problems,so as to effectively improve the security of signal transmission process.This paper analyzes 5G band services and C-band satellite operation conditions,and discusses effective countermeasures to the interference of 5G signals to C-band signals based on the actual measurement situation.
