EchoStar: 12 GHz Non-Coexistence Claims Manipulated

SpaceX's claims that EchoStar's Dish Network's proposed terrestrial fixed wireless service can't coexist with Starlink operations in the lower 12 GHz band (see 2409040035) are "a textbook example of how to manipulate a technical analysis to reach a predetermined conclusion," EchoStar said Friday in docket 20-443. A SpaceX study randomly places fixed 5G base stations, ignoring that their location is the key to sharing, and its analysis "was designed to fail," EchoStar said. The SpaceX analysis assumes fixed 5G systems must operate constantly at full power, when they actually can dynamically adjust their power output. EchoStar also submitted a study simulating a denser distribution of Starlink terminals than SpaceX's analysis, but with EchoStar fixed 5G base stations deliberately placed to minimize interference. It said the results show coexistence without interference is "widely feasible." Consultancy RKF Engineering conducted EchoStar's study.
