SpaceX says that if 12GHz spectrum is used for terrestrial 5G networks it could cause outages in Starlinks spacebased internet service up to threequarters of the time and make the service unusable for most users. Americans.
The company submitted a new technical analysis to the Federal Communications Commission this week saying in an accompanying letter to the commission that its study verifies what should be intuitive that a highpower terrestrial network would blow anyone away using satellite equipment. . high sensitivity. consumers must use to receive signals that comply with Commission and international energy restrictions on satellite downlink transmissions. As a result far fewer Americans will be able to connect using nextgeneration satellite services and those that remain will experience service degradation and regular outages.
Dish Network wants to be able to use the 12 GHz band for terrestrial 5G services and has been asking the FCC for permission since 2016. The agency opened an investigation in early 2021 to investigate the feasibility of enabling mobile services in the band while protecting users. users. historical interference operators. There is 500 megahertz of spectrum at stake here that is currently used for satellite broadcasting. SpaceX describes 12.212.7 GHz waves as its working frequencies for Starlink downlink connections.
If Dishs lobbying efforts are successful our study shows that Starlink customers will experience harmful interference 77% of the time and a complete service outage 74% of the time rendering Starlink unusable for most consumers. of US users SpaceX said in a statement on Starlnks website. location on the internet.
Meanwhile Dish pointed to rival analysis by RS Access and RKF Engineering Solutions that it says demonstrates the viability of inband coexistence. In an ex parte filing RS Access said that this analysis determines that 5G operations would have no effect on at least 99.85% of NGSO operations in the 12 GHz band and that since satellite operators have other downlink spectrum available the remote … Probability of
interference specifically in the 12.212.7 GHz portion would probably be imperceptible [sic] to consumers. … The engineering record is now complete regarding the feasibility of 5GNGSO coexistence and the Commission has a winwin opportunity where the 12 GHz band is unlocked for massive 5G opportunities enabling coexistence of NGSO the company stated.
Starlink clearly disagrees with this calling the RS Access study technically without merit and going further attacking Dishs record of not meeting construction requirements for its huge spectrum holdings and saying they shouldnt be change more spectrum rules to accommodate the company. . Dish has never delivered on its repeated promises to roll out a new terrestrial network using the exclusive licenses already stocked in its warehouses the Commission simply cannot give away more spectrum to any operator with this history of broken promises and inactive consumers SpaceX said. adding that Dish did not even meet the previous implementation requirements for the 12 GHz band in question.
Meanwhile the 12GHz 5G Coalition which includes Dish and other companies responded to the technical filing by saying its engineers and technical experts are reviewing the filing thoroughly and remain committed to working in good faith with the FCC and the parties involved. involved. stakeholders to ensure that the American public can reap the immense benefits of 5G services in this band.
