SpaceX is trying to enhance Starlink add speeds by tapping extra radio spectrum.
On Monday, the corporate requested permission from the Federal Communications Fee so as to add help for the 13.75 to 14.0GHz and 14.5 to 14.8GHz bands to its satellite tv for pc web {hardware}.
The FCC already cleared SpaceX to make use of the spectrum for “Earth-to-space” transmissions (aka importing) as a part of the corporate’s effort to improve Starlink with gigabit speeds. Nevertheless, as SpaceX’s submitting notes, present FCC guidelines require a minimal antenna diameter of 4.5 meters to function within the 13.75 to 14.0 GHz band, which is bigger than the diameter of SpaceX’s present dish fashions. So, it wants a waiver from the FCC.
SpaceX filed seven requests to make use of the spectrum throughout its lineup, together with the present Starlink dish, the Starlink Mini, the second-generation dish, and the now-defunct first-gen round dish.
In its requests, the corporate tells the FCC that utilizing the spectrum will assist resolve the “4:1 imbalance between downlink and uplink spectrum within the Ku-band to fulfill shopper demand for high-speed, low-latency satellite tv for pc broadband and real-time communications.” This guarantees to unlock “extra symmetrical broadband speeds” to Starlink customers, and energy “data-intensive real-time purposes, resembling videoconferencing.”
On the 13.75 to 14.0GHz band, SpaceX provides: “This 250 MHz of spectrum is especially appropriate for next-generation satellite tv for pc service, because it lies instantly adjoining to the 14.0–14.5 GHz uplink band that these SpaceX earth stations are already licensed to make use of.” Presently, Starlink can provide add speeds from round 20 to 40Mbps.
The foremost query is whether or not the elevated add bandwidth will come to present Starlink dishes or if new antenna {hardware} will probably be required. SpaceX didn’t instantly reply to a request for remark. Nonetheless, the request so as to add the bands for the unique Starlink dish raises hopes that the add improve will apply to older {hardware} as effectively.

Within the software, the corporate notes that “SpaceX’s UTs [user terminals], as modified, is not going to lead to publicity ranges exceeding the relevant radiation hazard limits,” suggesting the product must endure some change to make use of the spectrum, although this would possibly merely contain a software program replace.
SpaceX can be planning to supply gigabit speeds by way of Starlink, however the firm has indicated that clients might want to purchase the extra highly effective, enterprise-focused dish {hardware} to realize quicker efficiency. Nonetheless, the FCC did clear the corporate to function the Starlink community at greater energy ranges in January, that means different efficiency upgrades might be coming to present customers.

I have been a journalist for over 15 years. I acquired my begin as a colleges and cities reporter in Kansas Metropolis and joined PCMag in 2017, the place I cowl satellite tv for pc web companies, cybersecurity, PC {hardware}, and extra. I am at the moment based mostly in San Francisco, however beforehand spent over 5 years in China, overlaying the nation’s know-how sector.
Since 2020, I’ve coated the launch and explosive development of SpaceX’s Starlink satellite tv for pc web service, writing 600+ tales on availability and have launches, but in addition the regulatory battles over the growth of satellite tv for pc constellations, fights with rival suppliers like AST SpaceMobile and Amazon, and the trouble to broaden into satellite-based cellular service. I’ve combed by way of FCC filings for the most recent information and pushed to distant corners of California to check Starlink’s mobile service.
I additionally cowl cyber threats, from ransomware gangs to the emergence of AI-based malware. Earlier this yr, the FTC compelled Avast to pay shoppers $16.5 million for secretly harvesting and promoting their private data to third-party purchasers, as revealed in my joint investigation with Motherboard.
I additionally cowl the PC graphics card market. Pandemic-era shortages led me to camp out in entrance of a Finest Purchase to get an RTX 3000. I am now following how President Trump’s tariffs will have an effect on the business. I am at all times desperate to be taught extra, so please leap within the feedback with suggestions and ship me suggestions.
