据美国联邦通信委员会(FCC)官网近日消息,FCC通过了其70 GHz、80 GHz和90 GHz频段频谱规则的更新,以促进船舶和飞机的宽带接入,以及5G的回程服务。这一行动将促进频谱的有效利用,为发展新的宽带服务选择提供机会。 此次更新为71-76 GHz、81-86 GHz...
具体而言,本次通过的命令为71-76 GHz、81-86 GHz、92-94 GHz和94.1-95 GHz频段制定了新规则并更新了现有规则。新规则授权某些点对点链路到70 GHz和80 GHz频段,以方便使用这些频率访问飞机和船舶上的宽带服务。它们还允许使用更小和成本、更低的天线,以方便在70 GHz和80 GHz频带内提供回程服务。最后,这次的...
