Spectrum

The Federal Communications Commission launched a proceeding to consider innovative sharing models in 500 megahertz of spectrum in the 42 GHz band. This examination of sharing models in high-band spectrum could not only inform how this band might best be used—particularly by smaller wireless service providers—but also inform future uses of sharing models in spectrum management. With ever-increasing demand for wireless services and a finite supply of airwaves, it is more important than ever to focus on finding ways to share spectrum, a valuable resource.

In April 2023, the Federal Communications Commission’s Space Bureau and Wireless Telecommunications Bureau opened a proceeding to accept comments on filings by SpaceX and T-Mobile to establish supplemental wireless coverage from space.

The 2023 5G Challenge is offering a $7 million prize pool for participants who successfully integrate their radio access network (RAN) subsystems with multiple other RAN participant subsystems and outperform their peers. Teams have progressed in testing since starting the challenge in late March. After the first nine weeks of host lab testing, the initial nine contestants have passed Stage Two wrap-around emulation testing. The following RU contestants passed Stage Two testing:

According to the Federal Communications Commission's new National Broadband Map, there are 8.3 million Unserved locations in the U.S. The FCC published “LBR Wireless” files for 41 states. As I rushed to download the data, I didn’t know what that meant as they hadn’t ever published them before, so I skipped them. I now know that to mean “Licensed by Rule” wireless.

This Special Airworthiness Information Bulletin (SAIB) informs aircraft manufacturers, radio altimeter manufacturers, operators, and pilots of the continued deployment of wireless broadband networks in the 3.7-3.98 GHz bands (C-Band). C-Band wireless broadband deployment, which began in January 2022, is continuing to occur in phases for operations in the contiguous US.

Legislative Vote Summary:

A who’s who of former Federal Communications Commission leaders sent a letter to the chairs of the House and Senate Commerce Committees urging Congress to restore the FCC’s spectrum auction authority as soon as practicable. “As former leaders of the Federal Communications Commission, we have worked together, on a bipartisan basis, to lay the foundation for America’s global wireless leadership. Although our policy priorities at times differed, we share an understanding that central to Americans’ wireless success is the FCC’s spectrum auction authority,” the letter states.

The US Department of State, on behalf of the US Government, has submitted a proposal to the May 2023 Inter-American Telecommunications Commission (CITEL), which calls for opening the 3300-3400 MHz band for 5G mobile services within the Americas Region. If accepted as a regional proposal, CITEL would submit to the November 2023 World Radiocommunications Conference (WRC-23). If adopted by the WRC-23, the international Radio Regulations would be updated to identify this band as possible for 5G use in the Americas by countries that choose to do so.

The same day that SpaceX scored a big win on the proper use of spectrum, it became embroiled in a new fight over appropriate spectrum use. The new fight is with AT&T over SpaceX’s plans to enable calls from T-Mobile cellphones via SpaceX satellites. That type of service is called supplemental coverage from space (SCS) and is a market AT&T also is pursuing via a deal with satellite operator AST.

The Federal Communications Commission took a holistic approach to expand the use of over 1 gigahertz of prime mid-band spectrum in the 12 GHz bands 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 that would position the 12.7-13.25 GHz band to support flexible terrestrial wireless use, including 6G wireless services.
