The Federal Communications Commission earlier rejected SpaceX's application to add mobile communications services to its satellite service system because there was potential interference controversy over the frequency band SpaceX applied to use.
SpaceX's application includes the use of the 1.6/2.4GHz bands, the 2GHz bands, and the bands between 20200 and 2025MHz. However, the 1.6/2.4GHz bands may cause frequency interference with the existing bands used by satellite service provider Globalstar, and the 2GHz band may also cause interference with the services provided by broadband provider Dish.
Prior to this, Globalstar and Dish had opposed SpaceX's application for frequency band use, and the Federal Communications Commission also asked SpaceX to modify its application or prove that it would not cause potential interference problems.
SpaceX's Starlink has established a partnership with US telecom operator T-Mobile to expand the coverage of T-Mobile's communication services through satellite networking. At that time, it was mentioned that the new wave of low-orbit satellites to be launched next year will be embedded with T-Mobile's corresponding mid-band PCS spectrum (1900MHz specification) signal transmission and reception functions, allowing smartphones on the ground to communicate directly via satellite.
In its application, SpaceX stated that it hopes to be granted access to the relevant frequency bands, allowing mobile phones to connect to the satellite internet and make calls. The proposed communications services will include voice, messaging, and basic internet transmission, with theoretical upload speeds ranging from 3Mbps to 7.2Mbps and download speeds from 4.4Mbps to 18.3Mbps.
