If the proposed addition of the 12GHz spectrum to 5G goes forward, Starlink broadband terminals across America could be crippled, or so SpaceX has complained.
The Elon Musk biz made the claim [PDF] this week in a filing to the FCC, which is considering allowing Dish to operate a 5G service in the 12GHz band (12.2-12.7GHz). This frequency range is also used by Starlink and others to provide over-the-air satellite internet connectivity.
SpaceX said its own in-house study, conducted in Las Vegas, showed "harmful interference from terrestrial mobile service to SpaceX's Starlink terminals … more than 77 percent of the time, resulting in full outages 74 percent of the time." It also claimed the interference will extend to a minimum of 13 miles from base stations. In other words, if Dish gets to use these frequencies in the US, it'll render nearby Starlink terminals useless through wireless interference, it was claimed.
