FCC proposes opening up military radar airwaves to smartphones and IoT devices

Context & Ripple Effects
This 2015 proposal sits at the start of a decade-long FCC pattern of prying open government-held spectrum for commercial devices. The agency had just spent late 2014 redrawing market definitions on other fronts, including a plan to fold internet TV services into the pay-TV regulatory category.
What followed validates the radar-band move as a template rather than a one-off: further testing of LTE in unlicensed Wi-Fi spectrum in 2016, the 2020 unlocking of the 3.5GHz Citizens Broadband Radio Service band with OnGo support in iOS and Android phones, and by 2024 the full opening of all 1,200 megahertz of the 6GHz band to very-low-power devices aimed at wearables and AR/VR. The through-line is the FCC treating federal and incumbent spectrum as shareable inventory for the phone-and-IoT economy.
First-order effects
- Smartphone makers and IoT device manufacturers gain access to a new pool of mid-band airwaves that were previously reserved for military radar, expanding their radio design options at no auction cost.
- The military becomes a spectrum sharer rather than an exclusive holder, meaning defense radar operations must now accommodate commercial coexistence rules negotiated through the FCC process.
Second-order effects
- The sharing architecture pioneered here prefigures what became the CBRS model — dynamic, tiered access where federal users sit protected above commercial traffic — giving carriers and equipment vendors a second band to build OnGo-style services on.
- Incumbents in adjacent unlicensed territory, notably Wi-Fi interests, face a crowded field as each newly opened band brings cellular and low-power IoT traffic into frequencies they once treated as their own, sharpening coexistence fights at every subsequent FCC proceeding.
Third-order effects
- If the cadence holds — radar bands to CBRS to 6GHz — US spectrum policy structurally shifts away from exclusive licensed blocks toward layered sharing regimes managed dynamically, with the FCC acting as broker between federal incumbents and the device economy.
- The boundary between defense and civilian radio infrastructure blurs: SignalFrame's later Air Force grant to explore cellphone-based tracking of nearby IoT devices shows both directions of that exchange, with military needs shaping commercial tech and commercial device fleets becoming assets the military wants access to.
The trend: The FCC has been systematically converting federally held and lightly used spectrum — military radar bands, 3.5GHz, 6GHz — into shared commercial capacity for smartphones, wearables, and IoT.
