A 4G signal was successfully broadcast to regular cellphones on Earth by AST SpaceMobile, a company located in Texas. The signal originated from the company’s enormous BlueWalker 3 satellite. Gizmodo has reportedly discovered this.

During the month of June, technicians put the satellite through a battery of tests, during which it was used to send data at download speeds of more than 10 Mbps from outer space to mobile phones in Hawaii.

The experiment was carried out inside the frequency band that is serviced by the American operator AT&T. In addition to it, the Nokia RAN communication technology was utilized. AST SpaceMobile is in the process of getting ready to test the satellite while it is operating at 5G speeds.

“Achieving this milestone from an unmodified, standard cell phone on the ground connecting through our low Earth orbit satellite is another groundbreaking moment in telecommunications history,” Abel Avellan, chairman and CEO of AST SpaceMobile, said in the company’s statement.

Lynk Global has already put three satellites into orbit, with the goal of providing services from outer space to mobile phones located on Earth. This is a brand-new form of technology, and the Federal Communications Commission in the United States is now working on the design of a system that would enable businesses to deliver satellite communications straight to mobile phones.
