The test demonstrated the first-ever mobile broadband two-way video call in Japan using unmodified smartphones connected directly to satellites. Radio signals were transmitted from Rakuten Mobile’s gateway Earth station in Fukushima Prefecture, north of Tokyo, to one of AST SpaceMobile’s newly launched BlueBird satellites.
From there, the satellite relayed the signal to a smartphone in Tokyo, using a standard calling app on a regular device – no hardware modifications, no special accessories, no satellite mode; just a phone, a satellite and space-age technology.
Rakuten Mobile tested system compatibility across a range of smartphones available in Japan. The company conducted the trial under a preliminary test license and is now seeking approval for a full experimental license for further testing in the near future.
“We are delighted to achieve the first-ever mobile broadband two-way voice call in Japan between a smartphone and satellite, proving this groundbreaking technology once again,” commented Rakuten Group Chairman and CEO Mickey Mikitani. Notably, the technology is compatible with close to all smartphones, regardless of the manufacturer and system, or if it is the latest model or not. “[With the Rakuten Saikyo Satellite Service], since it’s broadband, users can not only send text messages or do voice calls, but can even stream videos, go on social media platforms and make video calls on messenger apps.”
