摘　　要：2020年4月初,美国联邦通信委员会(FCC)发布了在6 GHz频段共1200 MHz频谱上开放免执照业务的规则草案,并在4月23日公开会议上获得通过。至此,6 GHz频段将与5 GHz频段免执照业务频谱连为一体,使美国原有2.4 GHz、5 GHz频段的Wi-Fi频谱增加数倍,极大地提高了宽带连接能力。介绍了美国6 GHz频段免执照业务规则制定背景、现有主要业务及规则。At the beginning of April 2020,the Federal Communications Commission(FCC)issued a draft rule to open unlicensed services on a total of 1200 MHz spectrum in the 6 GHz frequency band,which was approved at an open meeting on April 23.By now,the 6 GHz frequency band will be integrated with the unlicensed service spectrum in 5 GHz band,which will increase the original Wi-Fi spectrum of the United States in the 2.4 GHz and 5 GHz bands by several times,greatly improving the broadband connectivity.This article introduces the background of rule making,existing main services and rules etc.for unlicensed service in the 6 GHz frequency band in U.S.
