FCC拟放宽超宽带设备规则：24年旧框架迎来全面现代化
汽车数字钥匙、手机找物、室内精确定位靠的都是同一项技术，超宽带（UWB）。美国联邦通信委员会（FCC）本周提出法规修订草案，拟全面现代化2002年确立的超宽带设备规则框架，在保护既有频谱用户的前提下，放宽制造商与用户的限制。
超宽带用极短的无线电脉冲传递信号，能实现厘米级定位：手机指向藏在沙发缝里的追踪器、汽车感应到主人口袋里的数字钥匙缓缓靠近，背后都是它在工作。现行规则制定于2002年，当时这项技术尚在起步，诸多定义与限制已跟不上今天的产品形态。
据联邦通信委员会的草案，新规将重新界定超宽带发射设备的认定标准等核心条款，回应两份业界请愿，一份来自博世公司（2019年提交），另一份来自汽车创新联盟、汽车连接联盟、FiRa联盟等机构组成的产业联盟（2025年12月提交）。草案同时强调，松绑不能以干扰联邦与非联邦既有频谱用户为代价。
这项拟规已开启公众评论：意见截止12月2日，回复意见截止2027年1月4日，案卷号为 ET Docket No. 26-245，可通过联邦通信委员会的电子评论系统提交。委员会将在审议全部意见后决定是否出台最终规则。（来源：美国联邦通信委员会）
FCC Proposes Modernized Rules for Ultra-Wideband Devices, Replacing 2002 Framework
The technology behind car digital keys, phone-based item finding, and precise indoor positioning is the same: ultra-wideband, or UWB. The Federal Communications Commission (FCC) this week proposed a comprehensive modernization of the ultra-wideband rules it set in 2002, loosening restrictions on manufacturers and users while protecting incumbent spectrum users.
UWB transmits information in extremely short radio pulses and can locate objects to within centimeters, which is how a phone can point you to a tracker lost in the couch, or a car can sense the digital key in its owner's pocket approaching. The current framework dates to 2002, when the technology was in its infancy, and many of its definitions and limits no longer match today's products.
According to the FCC's proposal, the new rules would revise core provisions including how a UWB transmitter is defined, responding to two petitions for rulemaking: one filed by Robert Bosch LLC in 2019, and another filed in December 2025 by an industry alliance including the Alliance for Automotive Innovation, the Car Connectivity Consortium, and the FiRa Consortium. The proposal stresses that any loosening must not interfere with incumbent federal and nonfederal spectrum users.
Public comments on the proposal are due Dec. 2, with reply comments due Jan. 4, 2027, in ET Docket No. 26-245, through the FCC's Electronic Comment Filing System. The changes would take effect only if the Commission adopts a final rule. (Source: Federal Communications Commission)
