Rakuten has acquired approval for the AST SpaceMobile check

Direct-to-satellite service trials are deliberate for the distant mountains of Japan’s northern islands

Rakuten Cellular introduced this week that it has acquired the primary license from Japanese authorities to start testing direct-to-mobile satellite tv for pc communications. The corporate stated it’s working with the AST SpaceMobile satellite tv for pc producer and the just lately launched BlueWalker 3 satellite tv for pc to supply clients with a ubiquitous community even the place there isn’t any terrestrial sign.

AST SpaceMobile differentiates its proposed service from different open-source cellular direct-to-satellite providers by claiming to construct the primary and solely unmodified cellular community. AST SpaceMobile launched the BlueWalker 3 satellite tv for pc in September aboard a SpaceX Falcon 9 rocket. The corporate introduced earlier this week that BlueWalker 3 had been efficiently deployed.

The BlueWalker 3 satellite tv for pc has a 693-square-foot antenna, which is the biggest array ever deployed underground, in response to AST SpaceMobile. BlueWalker 3 is AST’s second experimental satellite tv for pc, providing a glimpse into the way forward for AST SpaceMobile’s plans: 168 satellites referred to as BlueBirds, which the corporate hopes to ultimately launch to kind a community by Earth by Low Earth Orbit (LEO) satellites. . AST says it might probably construct as much as six of those satellites a month at its Texas manufacturing plant, and may attain world supply as soon as about 110 are in orbit.

Rakuten and AST SpaceMobile first introduced that they have been working collectively greater than a 12 months in the past. On the time, the businesses hoped to begin industrial service in Japan in late 2023 or early 2024. Rakuten Cellular acknowledged that to check communication with BlueWalker 3, the corporate utilized to the Tohoku Regional Communications Workplace of the Japanese authorities. The corporate utilized for a “Gateway check station” license, which it described in a press launch because the equal of a cellular station. Rakuten Cellular additionally went to the Kanto Communications Bureau to acquire a license for a Cellular Trial Station, which it described as just like a cellular station. Each businesses have agreed to the request, Rakuten Cellular stated.

With the dearth of labor and documentation, Rakuten Cellular stated it should put together a nationwide gateway, just like a cellular base station. The system will start working in Japan’s Fukushima prefecture, to assist Rakuten check and confirm direct communication between BlueWalker 3 and cellphones working in mountainous areas on the northern Japanese island of Hokkaido. Rakuten additionally revealed some key software program that AST SpaceMobile will combine into its community to help the hassle.

“To allow testing with Rakuten Cellular and different distributors, Rakuten Symphony will present quite a lot of software program from the Symworld product portfolio to AST SpaceMobile to combine into the corporate’s satellite tv for pc system and allow the cellular community “The software program to be built-in contains Rakuten Symphony’s vRAN (Virtualized Radio Entry Community) software program, OSS (Operational Assist System) and BSS (Enterprise Assist System),” stated Rakuten Cellular.

Whereas AST SpaceMobile is testing the BlueWalker 3 with Rakuten Cellular and different telcos, different non-national telecommunications (NTN) cell phone efforts are shifting ahead. Maybe essentially the most high-profile but is Apple’s deployment of “SOS through satellite tv for pc” on the iPhone 14 and iPhone 14 Professional, which launched earlier this week within the US and Canada, with plans to launch in different European international locations in December. Apple developed the service with satellite tv for pc operator Globalstar, contributing practically half a billion {dollars} from the Capital Business Fund to improve Globalstar’s floor stations with a particular high-power antenna design. In contrast to the AST SpaceMobile community, nevertheless, this service is restricted to iPhone 14 fashions solely, which have a Qualcomm modem that helps Globalstar’s n53 community.
