AT&T, Verizon Push FCC to Block SpaceX's Cellular Starlink Over Interference Concerns

AT&T and Verizon are advocating for the FCC to reject SpaceX's Starlink Cellular service, asserting that it would result in substantial network interference and a decline in service quality. The telecommunications titans contend that SpaceX's proposal could undermine their offerings by reducing network downlink throughput by an average of 18%.

AT&T, Verizon Challenge SpaceX’s Starlink Cellular Service, Citing Potential Network Disruption

AT&T and Verizon are urging the Federal Communications Commission (FCC) to reject SpaceX's Cellular Starlink service, designed to offer users comprehensive and efficient coverage.

Earlier this month, Verizon and AT&T submitted letters to the FCC asserting that the SpaceX Starlink system would result in network interference, diminishing the effectiveness of their product offerings for customers.

“Specifically, AT&T’s technical analysts show that SpaceX’s proposal would cause an 18% average reduction in network downlink throughput,” AT&T said in a document to the FCC.

PCMag initially reported on the document.

In June, SpaceX pushed to receive a waiver from the FCC to allow Starlink Cellular to operate beyond normal radio frequency parameters. The company said it would prevent interference with other networks despite an increase in radio emissions:

“Moreover, waiving the rule would avoid placing artificial caps on the number of satellites that an operator may use to provide supplemental coverage, which in turn would limit the number of end users that the network could benefit.”

SpaceX Faces Intense Scrutiny from Competitors as FCC Battle Over Starlink Interference Escalates

In a report by Teslarati, SpaceX corroborated its assertions by conducting its investigation in February, which appeared to demonstrate that interference was not a concern. Nevertheless, Verizon and AT&T conducted their investigations, which yielded significantly different conclusions.

Additionally, Verizon stated that:

“SpaceX’s proposal would undermine the Commission’s core goal of protecting incumbent terrestrial licensee operations from SCS satellite operations in adjacent bands by subjecting them to harmful interference.”

These are merely a few of the numerous organizations that have submitted complaints to the FCC regarding interference concerns. However, SpaceX is not ignoring the complaints. The companies are employing every available tactic to delay SpaceX's sanction.

It was stated last week:

“Indeed, each time that SpaceX has demonstrated that it would not cause harmful interference to other operators—often based on those parties’ own claimed assumptions—those competitors have moved the goalposts or have claimed their analysis should not have been trusted in the first place. These operators’ shapeshifting arguments and demands should be seen for what they are: last-minute attempts to block a more advanced supplemental coverage partnership and siphon sensitive information to aid their own competing efforts.”
