美国FCC拟拍卖25 MHz中频频谱：1675-1695 MHz与2020-2025 MHz可用于5G与卫星直连手机服务
美国联邦通信委员会（Federal Communications Commission，FCC）10月29日在 Washington 表决通过一项拟议规则制定通知，计划拍卖合计25 MHz的中频频谱，分别位于1675-1695 MHz与2020-2025 MHz频段，可用于5G等地面灵活使用网络，也可用于卫星直连普通手机的直连设备（direct-to-device，D2D）服务。
FCC表示，D2D技术近年投资与创新激增，过去一年已有超过450亿美元的D2D交易经FCC批准或提交待批，市场对D2D频谱的需求持续增长。此次拍卖程序随本次表决启动。
这项计划紧接一轮35亿美元的 AWS-3 库存频谱拍卖完成之后推出；按现行安排，160 MHz的上C波段频谱将于2027年7月前拍卖，政府计划到2028年通过拍卖提供最多400 MHz频谱供商业使用，其中包括2.7 GHz与7 GHz频段。
具体方案拟把1675-1695 MHz频段重新分配为固定与移动（航空移动除外）服务的共同主要用途，供新的非联邦使用，并作为移动卫星服务（MSS）的次要用途，用于国内太空补充覆盖（SCS）；该频段的安排取决于国家电信和信息管理局（NTIA）按相关法案对该频段所作研究的结论。方案同时拟为2020-2025 MHz频段增加一项用于国内SCS的次要MSS分配。
这项进一步拟议规则制定通知的文号为 FCC 26-70，案卷号包括 WT Docket Nos. 26-284、19-116 与 GN Docket No. 26-281，由主席 Brendan Carr 与委员 Anna Gomez、Olivia Trusty 表决批准，三人均发表单独声明。公众可按FCC程序就拟议方案提交意见。
FCC Proposes Auction of 25 MHz of Mid-Band Spectrum in the 1675-1695 and 2020-2025 MHz Bands for 5G and Direct-to-Device Services
The Federal Communications Commission (FCC) voted on October 29 in Washington to propose a new spectrum auction of 25 megahertz of prime mid-band spectrum in the 1675-1695 MHz and 2020-2025 MHz bands, for advanced services including direct-to-device (D2D) operations and flexible-use terrestrial networks such as 5G.
The FCC said D2D technology has seen a surge of investment and innovation, with more than $45 billion in D2D deal flow approved by or submitted to the FCC in the past year alone, driving growing demand for D2D spectrum. The October 29 vote starts the process for the latest FCC spectrum auction.
The plan follows the recent completion of a $3.5 billion auction of AWS-3 inventory spectrum, with 160 megahertz of Upper C-band spectrum to be auctioned by July 2027. In total, the administration plans to make up to 400 megahertz of spectrum available for commercial use through auction by 2028, including spectrum in the 2.7 GHz and 7 GHz bands.
Specifically, the notice proposes reallocating the 1675-1695 MHz band on a co-primary basis for fixed and mobile (except aeronautical mobile) services for new non-federal use, and on a secondary basis for mobile satellite service (MSS) for domestic supplemental coverage from space (SCS), subject to the outcome of NTIA's study of the band. It also proposes a secondary MSS allocation for domestic SCS in the 2020-2025 MHz band.
The action was taken by Further Notice of Proposed Rulemaking, FCC 26-70, in WT Docket Nos. 26-284 and 19-116 and GN Docket No. 26-281, with Chairman Brendan Carr and Commissioners Anna Gomez and Olivia Trusty approving and issuing separate statements. Interested parties may comment through the FCC's proceedings.
