“SpaceX and T-Mobile’s technique is woefully insufficient when it comes to the threat of destructive interference posed through their planned SCS deployments,” AT said.
Last month, the FCC requested comment on the request, noting that SpaceX had requested adjustments to its license for low-Earth orbit satellites “to load direct-to-cellular communication capability on up to 7500 Gen2 Starlink satellites. “They rely on the bands 1910-1915 MHz (Earth to Space) and 1990-1995 MHz (Space to Earth), also known as PCS G-Block, the FCC said.
The FCC supports satellite companies and cellular operators partnering to fill gaps in wireless networks. , unattended and unattended areas. ” But the FCC can still reject or ask for adjustments to the SpaceX/T-Mobile plan.
We reached out to SpaceX and T-Mobile and will update this article if we receive a response.
SpaceX recently said it plans to begin testing the satellite-to-cellular formula with T-Mobile later this year. Text messaging is expected to be the first service supported, with voice and policy added later.
The SpaceX/T-Mobile case also drew responses from the Rural Wireless Association, an industry organization for small rural wireless operators, and Omnispace, which is partnering with Ligado for a satellite phone system.
RWA told the FCC that it implied “that proposed operations through T-Mobile and SpaceX may cause interference from channels adjacent to licensees’ constant network and cellular operations in the bands 1895-1910 MHz and 1975-1990 MHz (“PCS C-Block”) in rural and remote areas. “
SpaceX told the FCC that its “direct-to-cellular formula will work by causing destructive interference or requiring coverage of any other properly legal service in those bands” and “protect adjacent band operations from destructive interference. “
But according to RWA, “SpaceX does not offer this conclusion, nor does it propose to put protections in place to ensure there is no adjacent channel interference. “SpaceX and T-Mobile also “did not “provide the effects of box testing that would allow the public to analyze potential interference from adjacent channels,” the rural wireless organization said. Omnispace also told the FCC that the SpaceX/T-Mobile plan would interfere with existing cellular satellite service networks.
Another presentation presented two weeks ago through the National Radio Astronomy Observatory, a government-funded think tank. The organization said the SpaceX/T-Mobile plan would cause destructive interference in parts of the national radio silence zone. SpaceX issued a reaction saying the organization’s astronomy considerations “seem most productive addressed in the Commission’s general regulation to identify industry-wide regulations for the SCS. “
Yesterday, the FCC sided with SpaceX in a separate war over spectrum use. As noted, the FCC rejected a proposal through Dish Network for cellular service in the 12. 2-12. 7 GHz band, claiming that Dish’s plan would cause destructive interference to satellite broadband service. .
