SpaceX warns 5G plan would deny Starlink to most Americans

Space News by Jason Rainbow — June 21, 2022

SpaceX warned June 21 that its Starlink broadband network would become unusable for most Americans if a proposal to use the 12 GHz band for terrestrial 5G is approved.

U.S.-based satellite broadcaster Dish Network is seeking permission to operate a high-power mobile service in the 12 GHz band, which is part of the Ku-band spectrum that Starlink, OneWeb and other satellite operators use to connect with user terminals.

In a letter to the Federal Communications Commission, SpaceX said tests it conducted in Las Vegas shows how the proposed network would cause Starlink users to “experience harmful interference” more than 77% of the time.

Starlink would be “subjected to total outage of service 74% of the time,” wrote David Goldman, SpaceX senior director of satellite policy.

“This analysis verifies what should be intuitive—that a high-power terrestrial network would blow out anyone using the high-sensitivity equipment satellite consumers must use to receive signals that comply with Commission and international power restrictions on satellite downlink transmissions,” he said.

“As a result, vastly fewer Americans could be connected using next-generation satellite services, and those that remain would experience degraded service and regular network outages.”

SpaceX FCC broadband feud vs. Dish, Michael Dell affiliate worsens

Vigourtimes by Beverley Rayner 6/22/2022

Elon Musk’s SpaceX on Tuesday ramped up a battle over broadband regulations with Dish Network and an affiliate of billionaire Michael Dell, calling for the FCC to address lingering disputes over broadband use that could interfere with its Starlink satellite internet network.

At the heart of the dispute is use of the 12-gigahertz band, a range of frequency used for broadband communications, and the frequency’s ability to support both ground-based and space-based services.

In January 2021, the Federal Communications Commission issued a notice asking for comment on how to best use the 12-gigahertz band. Dish and RS Access, funded by Dell’s investment firm, published studies arguing that ground-based 5G networks could share the frequency with low Earth orbit satellite networks, such as Starlink or OneWeb.

SpaceX filed its analysis of the Dish and RS Access studies on Tuesday, claiming it needed to correct what it called “some of the most egregious assumptions” in the reports, arguing Starlink users would see interference to the point of causing service outages for customers “74% of the time.”

Musk’s company called on the FCC “to investigate whether DISH and RS Access filed intentionally misleading reports,” noting that the studies did not match findings from Dish two years earlier that called sharing usage “not viable.”

SpaceX accuses Dish of 'faulty' analysis in ongoing battle over 5G spectrum

Engadget by S. Dent 6/24/2022

Its use of 12GHz frequencies would render Starlink 'unusable for most Americans.'

Dish's plan to use 12GHz radio spectrum for its 5G network could drastically affect the Starlink satellite internet network, SpaceX said in a letter to the FCC. "If Dish’s lobbying efforts succeed, our study shows that Starlink customers will experience harmful interference more than 77 percent of the time and total outage of service 74 percent of the time, rendering Starlink unusable for most Americans," wrote SpaceX senior director David Goldman.

Dish has asked the FCC to allow it to use the 12Ghz band for a terrestrial 5G network, despite potential satellite interference with Starlink and other services, including its own Dish Network. Dish and its allies in the 5Gfor12GHz coalition recently published research saying that doing so would be "highly feasible" and that Starlink and similar services "will experience zero harmful interference with 5G."

However, SpaceX called the analysis "faulty" and told the FCC that "no reasonable engineer" would believe the studies. "SpaceX urges the Commission to investigate whether Dish and [Dell-owned] RS Access filed intentionally misleading reports," it said. The Elon Musk-owned company also pointed out that the studies don't align with Dish's own filings from December 2019 that "concurrent sharing of spectrum... is not viable in the 12 GHz band."
