SpaceX says that if 12 GHz spectrum is used for terrestrial 5G networks, it could disrupt three-quarters of its Starlink space-based Internet service and make the service appear “unusable for most Americans.”
The agency submitted new technical analysis to the Federal Communications Commission this week, saying in an accompanying letter to the commission that its research “verifies what should be intuitive – that a high-power terrestrial network would blow up anyone using high-sensitivity equipment satellites.” Customers must use commissions on satellite downlink transmissions and receive signals that comply with international power restrictions. As a result, very few Americans can connect using next-generation satellite services, and those who remain will experience degraded service and regular disruptions. ”
Dish Network wants to be able to use the 12 GHz band for terrestrial 5G services and has been seeking permission from the FCC since 2016. The company opens one Investigation in early 2021 Focus on the possibility of allowing mobile services in the band, as well as protect those in charge from interference. It has 500 MHz of spectrum which is currently used for satellite broadcasting. SpaceX describes 12.2-12.7 GHz airwaves as a “workhorse frequency” for Starlink downlink connections.
“If Dish’s lobbying efforts are successful, our research shows that Starlink customers will experience malicious interference more than 77% of the time and total service disruptions 74% of the time, making Starlink unusable for most Americans,” SpaceX claimed. Statement on Starlnk’s website.
Meanwhile, Dish RS Access and RKF Engineering Solutions point to rival analysis that says it demonstrates the potential for coexistence in the band. In an earlier filing, RS Access stated that the analysis was “that 5G operations in the 12 GHz band will have no effect on at least 99.85% NGSO operations” and that because satellite operators have other downlink spectrum available, the possibility of “remote.”
Interference, especially in the 12.2-12.7 GHz part, will probably go unnoticed [sic] To consumers. প্রক The engineering record on the possibility of 5G-NGSO coexistence is now complete, and the Commission has a win / win chance where 12 GHz bands have been unlocked for large 5G opportunities for NGSO co-existence, ”the company claimed.
Starlink obviously takes issue with this, calling the study of RS Access “technically incompetent” and goes further, swiping on the record of not providing build-out requirements for Dish’s huge spectrum holdings and saying that any more changes to the spectrum to adjust the spectrum. Should not be. Institutions. “Dish has not repeatedly fulfilled its promise to set up a new terrestrial network using exclusive licenses already stored in its warehouses – the commission can only offer broken spectacles and no more spectrum to any operator with this track record of stuck customers,” SpaceX added. The Dish issue also did not meet the previous installation requirements for the 12 GHz band.
Meanwhile, the 5G for 12 GHz coalitionRespondents to the technology submission, including Dish and other companies, said its engineers and technology experts “are deeply reviewing the filing and are committed to working in good faith with the FCC and stakeholders to ensure that the American public is able. The band has plenty of 5G services.” Take advantage. “
