In an email urging users to contact the Federal Communications Commission and members of Congress, SpaceX yesterday said a Dish plan to use the 12 GHz spectrum band for mobile service will cause "harmful interference [to Starlink users] more than 77 percent of the time and total outage of service 74 percent of the time, rendering Starlink unusable for most Americans." Those percentages come from a study SpaceX submitted to the FCC last week, which claims mobile service in the 12 GHz band would interfere with Starlink user terminals that use the same spectrum for downloads.
