Sharing

As part of an assessment conducted with the Department of Defense, NTIA significant progress in finding potential spectrum sharing options for the 3450-3550 MHz band. Federal operations in the 3450-3550 MHz band include shipborne, airborne, and land-based systems — primarily radars. Our report points to a clear possibility for real time spectrum sharing that would protect these critical missions, while providing attractive opportunities for commercial business.

2020 looks like it will be your year to get 5G—but only in the sense of having that signal on your phone, not in the sense of knowing quite what it’s supposed to be or using it to its full potential. A new report from the network analysis firm Opensignal advises that while this revamp of mobile broadband is poised to reach far more of the US, it will do so in ways that may leave both carriers and their customers feeling some wireless whiplash.

On Aug 2, 2019, Reps Debbie Dingell (D-MI) and Fred Upton (R-MI) sent a letter to Federal Communications Commission Chairman Ajit Pai about a recent Notice of Proposed Rulemaking in the 5.9 GHz band, urging the FCC to take a technology neutral approach to allow for testing of the Cellular Vehicle-to-Everything (C-V2X) communications platform. 

Power companies, first responders and railroads are intensifying criticism of the Federal Communications Commission’s plan to allow Wi-Fi traffic on the 6 GHz band of airwaves they currently use.

Trade group TechNet, which counts AT&T and Verizon among members, is sounding the alarm over language in the Senate defense bill, S. 1790, ordering the Defense Department to create a test-bed program for “innovative technologies and techniques to facilitate” spectrum sharing between 5G service providers and incumbent airwaves occupants. Wireless heavyweights view this language as a Pentagon power grab over 5G and are lobbying to strip it from the bill before the House and Senate settle on a consensus version.

Microsoft, Google and the Wireless Internet Service Providers Association (WISPA) are urging the Federal Communications Commission to allow co-channel spectrum sharing in the C-band. The proposal would allow fixed wireless operators to use the same spectrum band as incumbent users, who are comprised largely of satellite operators that use the spectrum for their earth stations. The FCC is currently pondering how it might best make a portion of the C-band, comprised of spectrum between 3700 and 4200 MHz, available for wireless services.

As the Senate geared up to pass its defense policy bill, the office of Minority Leader Chuck Schumer (D-NY) unsuccessfully pushed to add language that would require that a provision mandating Pentagon-led test beds to examine sharing 5G airwaves come with a requirement that the government “solicit and consider the input of commercial wireless service providers, equipment manufacturers, and firms developing and operating spectrum sharing technologies” as part of planning. 

Given its past success and future potential, what challenges do Wi-Fi and its advocates face?

The Federal Communications Commission proposed to reallocate spectrum in the 1675-1680 MHz band for shared use between incumbent federal users and new, non-federal flexible-use wireless operations. The 1675-1680 MHz band currently is used for weather forecasting services. But for several years spanning two Administrations, the President’s budget proposals have called for this band to be auctioned for flexible use, subject to sharing arrangements with federal weather satellites. The Notice of Proposed Rulemaking adopted takes the FCC’s first step toward accomplishing that task.

House Armed Services Chairman Adam Smith (D-WA) confirmed that anxiety over Chinese telecom giants’ wireless advances could creep into House lawmakers’ must-pass defense policy legislation. “There might be a couple things on 5G that we include,” said Chairman Smith.
