联邦通信委员会宣布上C波段拍卖2027年4月27日开拍：将释放3248张牌照、160兆赫中频段频谱
华盛顿 — 美国联邦通信委员会（FCC）11月13日宣布，上 C 波段频谱拍卖（第 115 号拍卖）定于 2027 年 4 月 27 日开始竞拍，将释放 3.98 至 4.14 GHz 频段内共 3,248 张灵活用途牌照，供下一代无线服务使用。
这批牌照覆盖美国本土，合计 160 兆赫频谱，按部分经济区划分、每区设 8 个 20 兆赫区块，以非成对方式发放；牌照期限为 15 年、可续期。4.14 至 4.16 GHz 的 20 兆赫将留作保护带，不在此次拍卖之列，原卫星业务将向更高频段重新安置。
FCC 表示，这次拍卖是为回应市场对中频段频谱的强劲需求，并落实国会在 2025 年法律（Pub. L. 119-21）中的指令：以竞争性竞拍方式发放 3.98 至 4.2 GHz 频段牌照，且须在 2025 年 7 月 4 日起两年内、即 2027 年 7 月 4 日前完成。拍卖程序将先进行升时钟竞价、再进入具体频率分配阶段。
竞拍开始日期由 FCC 经济与分析办公室和无线通信局在 11 月 13 日的新闻稿中正式对外宣布，拍卖的专门网站为 FCC 第 115 号拍卖页面，潜在竞拍者须自行评估频段清理安排等技术与市场因素。

FCC Sets Upper C-Band Auction for April 27, 2027: 3,248 Licenses Covering 160 MHz of Mid-Band Spectrum
WASHINGTON — The Federal Communications Commission (FCC) announced on November 13 that bidding in the Upper C-band auction, designated Auction 115, is scheduled to commence on April 27, 2027, offering 3,248 new flexible-use licenses in the 3.98 to 4.14 GHz band for next-generation wireless services.
The licenses cover the contiguous United States and total 160 megahertz of spectrum, offered on an unpaired basis in eight 20-megahertz blocks by partial economic area. Licenses will be issued for renewable 15-year terms. The 20 megahertz at 4.14 to 4.16 GHz will serve as a guard band and will not be auctioned, while incumbent satellite operations are repacked into higher frequencies.
The FCC said the auction responds to surging demand for mid-band spectrum and to congressional direction in Public Law 119-21 requiring licenses in the 3.98 to 4.2 GHz band to be granted through competitive bidding completed no later than July 4, 2027. The auction will use an ascending clock phase followed by an assignment phase for frequency-specific licenses.
The start date was announced by the FCC's Office of Economics and Analytics and its Wireless Telecommunications Bureau. The Commission reminded potential bidders that they are responsible for evaluating technical and marketplace factors, including the band-clearing process.
