跟进：FCC公布无人机800兆赫命令全文：新增脚注点名SpaceX相邻频段收购
美国联邦通信委员会（FCC）10月30日公布了无人机800兆赫频段命令（FCC 26-72）的正式全文。本站10月29日已报道，FCC当日以3比0表决通过该命令，取消一项源于1991年的机载使用限制，开放800兆赫蜂窝频段中50兆赫频谱供无人机使用。此次公布的19页全文与此前公开的草案基本一致，同时出现了一处草案没有的新增内容。
命令确认，824至849兆赫与869至894兆赫两段频谱可用于无人机的指挥控制、通信与载荷数据传输；新规将在《联邦公报》刊登30天后生效，截至本周日该命令尚未刊登。
新增的脚注29点名了SpaceX：FCC无线电信局已于7月1日批准Grain Management收购T-Mobile在817至824兆赫与862至869兆赫的牌照，SpaceX已于10月9日申请接手这批紧邻无人机频段的牌照。FCC在脚注中表示，预期无人机与SpaceX计划中的手机直连服务能够在相邻频段共存，并称其意图是「让两段频谱都得到充分利用」。SpaceX未出现在草案援引的运营商与厂商名单中，这条脚注是在草案公开后、表决前补入的。
全文还确认，无人机配送公司Zipline提出的降低功率运行请求仍被拒绝。FCC下一次无人机频谱表决定于11月19日，议题包括450兆赫控制链路与24吉赫无人机探测雷达。需要说明的是，本命令只解决频谱问题，无人机超视距常态飞行仍有待联邦航空局（FAA）的Part 108规则出台，该规则的法定截止日期为12月7日。

Follow-Up: FCC Releases Full Text of Drone 800 MHz Order, Adding a Footnote That Names SpaceX's Adjacent-Band Bid
The Federal Communications Commission on October 30 released the full adopted text of its 800 MHz drone order (FCC 26-72). As GSM reported on October 29, the commission voted 3-0 that day to lift an airborne-use restriction dating to 1991 and open 50 megahertz of 800 MHz cellular spectrum to unmanned aircraft. The 19-page adopted text tracks the earlier public draft closely, with one addition the draft did not carry.
The order confirms that the 824-849 MHz and 869-894 MHz bands may be used for drone command and control, communications and payload links. The rules take effect 30 days after publication in the Federal Register, which had not printed the order as of Sunday.
New footnote 29 names SpaceX. It records that the FCC's Wireless Telecommunications Bureau approved Grain Management's purchase of T-Mobile's licenses at 817-824 MHz and 862-869 MHz on July 1, and that SpaceX applied on October 9 to take over those licenses, which sit directly beside the drone band. The FCC states in the footnote that it expects drones and SpaceX's planned direct-to-phone service to coexist in the adjacent bands, and that it intends for both bands to be fully utilized. SpaceX was not among the carriers, drone makers or chipmakers cited in the draft; the footnote was added between the draft and the vote.
The text also confirms that drone delivery company Zipline's request for reduced-power operations remains declined. The FCC's next drone spectrum votes are set for November 19, covering 450 MHz control links and 24 GHz drone-detection radar. The order addresses spectrum only: routine beyond-visual-line-of-sight drone flight still awaits the Federal Aviation Administration's Part 108 rule, which faces a statutory deadline of December 7.
