PCMag reports that Dish Network has been lobbying the FCC to use the 12 GHz band to operate its 5G cellular network on the ground, but the operators have engaged in a long and intense tug of war.
On Tuesday, SpaceX again told the FCC that opening up 12 GHz spectrum to wireless network providers such as Dish Network could pose a direct threat to the availability of Starlink services.
The company wrote in the letter: SpaceX submitted an extensive technical analysis showing that the mobility services envisioned by Dish and RS Access would materially and severely disrupt the availability of next-generation satellite services.
SpaceX added: The Starlink antenna itself is highly sensitive to the radio spectrum operating in the same frequency band, and if other businesses were allowed to use the 12 GHz spectrum on the ground, the company would be forced to separate the Starlink receiver from the cell site by at least 13 miles (21. kilometer).
When this step is reached, American customers who can use the next-generation Starlink Internet service will be greatly discounted, and the remaining users will have to endure the decline in service quality and frequent communication interruptions.
Even so, Dish Network told PCMag that it was currently reviewing the SpaceX research report and could not immediately comment on the matter.
Meanwhile, as a member of the “5G for 12GHz” alliance, the company cited a study sponsored by RKF Engineering that said satellite internet services could coexist harmoniously with 5G services in the 12 GHz band.
