NextNav Files Supplement to Earlier Report on PNT in 900 MHz Band
NextNav filed at the FCC a supplement to its early engineering report, addressing interference issues raised by the company’s proposal that the FCC reconfigure the 902-928 MHz band “to enable a high-quality, terrestrial complement” to GPS for positioning, navigation and timing services (see 2503030023). The supplement filing, posted Thursday in docket 25-110, slammed critics of the earlier report (see 2504280045).

“Rather than seriously addressing the NextNav Technical Study, commenters who oppose NextNav’s proposal have advanced numerous misconceptions about NextNav’s proposal,” the filing said. These commenters fail “to provide rigorous technical analysis to back up their claims that coexistence between 5G [new radio] and unlicensed use is not feasible.” While the earlier technical study “continues to stand on its own, this supplemental report further validates its assumptions and conclusions,” NextNav said.
The “supplemental technical filing confirms that 5G operations will not cause unacceptable levels of interference to unlicensed Part 15 devices in the lower 900 MHz band, and that unlicensed operations can continue to operate across the entire lower 900 MHz band,” emailed Renee Gregory, NextNav's vice president of regulatory affairs. “Today’s filing further demonstrates NextNav’s commitment to ensuring that this proceeding is guided by facts, sound engineering, and rigorous technical analysis.”
