Smartphones successfully make direct video calls to satellites! What are the possibilities of Rak...

On April 23, 2025, Rakuten Mobile held a press conference. Rakuten Mobile and AST SpaceMobile announced in April 2025 that they had successfully conducted the first end-to-end direct video call between a low-orbit satellite and a commercially available smartphone in Japan. This is a major step forward in Rakuten Mobile's goal to provide "Rakuten's Strongest Satellite Service Powered by AST SpaceMobile". This test was conducted while AST SpaceMobile's low-orbit satellite "BlueBird Block 1" was passing over Fukushima Prefecture. Rakuten Mobile's gateway earth station installed in Fukushima Prefecture transmitted radio waves to the satellite, which was then received by the smartphone via the satellite. As a result, a video call was successfully made using a calling app between Fukushima Prefecture and a commercially available smartphone in Tokyo. A major feature of this satellite communication technology is that it uses the frequency band used by existing mobile phone services, making it possible to use it on almost all commercially available LTE-compatible smartphones. In addition, the AST SpaceMobile satellite used is said to be very large (about 36 times larger, 223 m²) compared to competitors' satellites. "Rakuten's Strongest Satellite Service" aims to cover the entire area of ​​Japan, including mountainous areas and remote islands that were previously out of reach of mobile communications, and is expected to be used as a means of communication in emergencies such as disasters. Service provision in Japan is scheduled to begin in the fourth quarter of 2026. Rakuten Mobile says that with this technology, it will work to create an environment where broadband communications can be used regardless of location. 00:00 Opening 00:12 Presentation by Chairman Mikitani 28:07 Q&A 48:57 Interview with Chairman Mikitani ▼Rakuten Mobile is recommended for communications overseas!
