> On Tuesday, the FCC sent a list of additional questions to SpaceX as the US regulator considers whether to approve or reject the company’s application to operate the Starlink cellular service over the 1910 to 1995MHz radio bands.
> Another request asks SpaceX to provide “a map with projected beam coverage” for the US, showing the maximum and typical power levels of the satellite cellular service. The FCC also wants to know how the company can shut down the cellular Starlink system in the event interference arises over certain geographic areas.
> The letter arrives when other companies have expressed concerns to the FCC about the Starlink cellular system causing interference. US-based Omnispace, a satellite communications provider, even told the Commision that the interference is unavoidable for its own S-Band satellites, which operate using the 1980-2010MHz frequency.
> “Because Omnispace’s satellites are in constant motion, as are SpaceX’s, the interference Omnispace will see will be constant and pervasive for any of our satellites operating at distances 5,400 km from any US territory where SpaceX is operating a single satellite in its proposed SCS system,” the company said back in August. Omnispace also created a map, showing an "exclusion zone" to depict the regions the alleged Starlink interference would occur.
