5G干扰测试仪在广播电视与电信业务干扰排查中的应用

Application of 5G Interference Tester in Interference Detection of Broadcast Television and Telecommunications Services

5G基站的大规模建设,在有效提升人们对互联网通信满意度的同时,带来了新的问题。因中国广电、中国移动共建共享的5G频段(700 MHz)与原规划给中央广播电视节目无线数字化覆盖的地面数字电视段频有重叠,在地面数字电视还未完成清频、5G基站大规模建设的时期,5G基站信号对地面数字电视信号产生了干扰。江西省多地广播电视台相继出现了地面数字电视受5G信号干扰的现象,严重威胁到安全播出。如何快速定位5G干扰,成为一个新的课题。基于此,介绍广播电视与电信业务干扰排查流程,阐述5G干扰测试仪在干扰排查中的实际应用。

The large-scale construction of 5G base stations has brought new problems while effectively improving people’s satisfaction with internet communication.Because the 5G frequency band(700 MHz)jointly shared by China Radio and Television and China Mobile overlaps with the terrestrial digital television segment frequency originally planned for the wireless digital coverage of central radio and television programs,the 5G base station signal interferes with the terrestrial digital television signal during the period when the terrestrial digital television has not yet completed the frequency clearing and the large-scale construction of 5G base stations.The phenomenon that terrestrial digital television is interfered by 5G signal has appeared successively in many broadcasting stations in Jiangxi province,which seriously threatens the safety of broadcasting.How to quickly locate 5G interference has become a new topic.Based on this,this paper introduces the interference detection process of radio,television and telecommunications services,and expounds the practical application of 5G interference tester in interference detection.
