Your phone loses signal in a parking garage for a simple reason. High frequencies bounce off concrete. Low ones go through it. That's why the FCC notice on November 10 matters more than it looks. The commission accepted SpaceX's application to take over Grain Management's 800 MHz licenses: 546 paired licenses across 3,224 counties, covering about 100% of the US population, on a band almost every phone already supports. When the deal was announced in October, Elon Musk called it "the last critical piece of the spectrum puzzle needed for SpaceX to provide complete phone coverage in America." Once it closes, SpaceX would hold up to 89 MHz in any market. AT&T, Verizon and T-Mobile each sit on roughly 300 MHz. SpaceX is betting that satellites and towers working as one network can do more with a fraction of that, and Qualcomm is supplying the radios for tens of thousands of cell sites from 2027. I've driven enough empty roads staring at zero bars to know who needs this most. Comments are due December 1, and I'll be watching that docket like a launch countdown.
