AST SpaceMobile, the Texas-based rival of SpaceX, has been approved for an experimental license to test a low-earth orbit satellite that is the prototype for its planned mobile phone connectivity from space.

The US Federal Communications Commission granted the license on Friday, July 11th, giving the company the ability to test a satellite that has a phased-array antenna that enables it to function as a cell tower from space. Known as FM1, it is at the center of the 5G broadband provider's hopes to build a satellite-to-phone internet system. The FCC has assigned the callsign WP2XRX, which expires on July 1st, 2027. A copy of the license online shows that it authorizes experimental operation only on 37.5 GHz-42 GHz, and 2.235 GHz, 2.245 GHz for mobile satellite services.

The amateur radio frequencies, 430-440 MHz, also appear on the license. The 5G service requested those frequencies to conduct telemetry, tracking, and telecommand between ground stations and its satellites. The company seeks FCC approval for operation of 248 low-earth orbit, non-geostationary satellites. Its present license only permits five.

AST SpaceMobile has been developing its network in association with AT&T and Verizon. SpaceX is partnering with T-Mobile.
