2023年5月18日，美国联邦通信委员会 (FCC) 通过了编号为FCC 23-35 的新规则。规则标题为“关于在 57-71 GHz（60 GHz）频段运行的短距离雷达技术的更新、更灵活的

规则”。使用短距离雷达技术的设备包括监测车内高温环境传感器使用的雷达、医疗保健监控设备以及用于建筑、紧急救援和商业环境的无人机。新规则将为这些设备进入消

费者和商业市场创造更有效的时间表。

FCC EMPOWERS SHORT-RANGE RADARS IN THE 60 GHz BAND FOR TECH LIKE ‘HOT CAR’ SENSORS, HEALTHCARE MONITORING, EMERGENCY RESPONSE DRONES

The Federal Communications Commission today adopted new, more flexible rules for the 60 GHz spectrum band to support state-of-the-art radar technology.  Many cutting edge technologies rely on short-range radars to support important applications including alerting drivers to children left in dangerously hot cars, improving mobility and health outcomes by detecting hand gestures and respiratory functions, and assisting drones in construction, emergency rescue, and commercial settings.  The new rules will accelerate the time for these devices to reach the marketplace for use by consumers and in commercial applications.

The new rules will provide opportunities for unlicensed field disturbance sensor (radar) devices to operate in the 60 GHz (57-71 GHz) band and foster the creation of innovative products and services while also ensuring coexistence with other users in the band.  The 60 GHz band has long allowed important unlicensed operations by users of indoor/outdoor communication devices that support the WiGig standard and wireless local area networking devices.

The Report and Order adopted today by a vote of the full Commission expands the permissible uses for unlicensed mobile radar operations beyond the currently limited types of permissible uses.  Prior to adopting these rules, the Commission had issued targeted waivers from the restrictive operations to permit operations such as the life-saving “hot car” monitors.  The new rules will establish long-term, predictable guidelines to empower even more consumer-friendly and economy-driving innovations.

As with so many spectrum policy achievements, these new rules lean on compromises between interests and cross-industry cooperation agreements.  The final rules draw heavily from agreements between parties that provide unlicensed communication devices in the band and the parties interested in developing unlicensed radars to support new applications.  The FCC commends the industry on reaching consensus on technical and operational guidelines that will allow continued innovation for both communication devices and radar applications in the 60 GHz band.

Action by the Commission May 18, 2023 by Report and Order (FCC 23-35).

同日，FCC还通过了编号为FCC 23-36 的新规则。规则标题为“扩大 12.2-12.7 GHz 频段的灵活使用；将 12.7-13.25 GHz 频带扩展用于移动宽带或其他扩展用途”。对于12.2GHz频段，FCC将确保目前及将来包括卫星互联网在内的卫星服务的延续和发展；对于12.7GHz FCC考虑将部分或者全部频谱资源用于移动宽带（5G）或其他扩展应用。

FCC MOVES FORWARD ON 12 GHz PROCEEDING

New Rules Preserve Portion of the Band for Advanced Satellite Broadband While Considering How to Promote Advanced Terrestrial Broadband in the Rest of the Band

WASHINGTON, May 18, 2023—The Federal Communications Commission today took a holistic approach to expanding use of over 1 gigahertz of prime mid-band spectrum in the 12 GHz band by ensuring stable spectrum access for current and next-generation satellite service while also empowering advanced terrestrial wireless services.   The FCC adopted rules to preserve spectrum between 12.2-12.7 GHz for current and future satellite services.   The FCC also proposed policies which would position the 12.7-13.25 GHz band to support flexible terrestrial wireless use, including 6G wireless services.

In the 12.2 GHz band, the FCC ensures the present and future for satellite services, which are relied upon by millions of people across the country, by declining to authorize two-way, high- powered terrestrial mobile use due to a significant risk of harmful interference to existing and emergent services, particularly in the growing satellite broadband market.   The Commission sought comment on other potential changes to expand the efficient use of the band, including for terrestrial fixed use or unlicensed use.

In the 12.7 GHz band, the FCC proposed to repurpose some or all of the band for mobile broadband or other expanded use.   The Commission sought comment on options for grandfathering, relocating, and/or repacking incumbent non-federal licensees, as well as on alternative approaches that would use sharing methodologies among incumbents and new entrants.

Today’s approach paves the way for advanced satellite and terrestrial services to access spectrum resources to support consumer needs, helping to connect everyone everywhere to advance wireless services and supercharge the American economy.

Action by the Commission May 18, 2023 by Report and Order and Further Notice of Proposed Rulemaking (FCC 23-36).
