Rakuten will get approval for AST SpaceMobile testing

Direct-to-satellite service exams are deliberate for the distant mountains on Japan’s northernmost island

Rakuten Cellular introduced this week that it has obtained preliminary licenses from Japanese regulators to start testing direct-to-mobile satellite tv for pc communication. The corporate stated it’s working with satellite tv for pc maker AST SpaceMobile and its just lately launched BlueWalker 3 satellite tv for pc to supply prospects with ubiquitous connectivity even the place there isn’t terrestrial cell protection.

AST SpaceMobile has differentiated its deliberate service from different burgeoning direct-to-satellite cell broadband providers by claiming to be constructing the primary and solely space-based mobile broadband community accessible by off-the-shelf unmodified cell phones. AST SpaceMobile launched its BlueWalker 3 satellite tv for pc in September on board 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 most important array that has ever been deployed in low Earth orbit, in line with AST SpaceMobile. The BlueWalker 3 is AST’s second take a look at satellite tv for pc, offering a glimpse into the longer term AST SpaceMobile has deliberate: A constellation of 168 related satellites referred to as BlueBirds, which the corporate is hoping to finally launch to create a worldwide community of Low Earth Orbit (LEO) satellites. AST says it may construct as much as six of those satellites a month at its Texas manufacturing facility, and that world protection needs to be reached as soon as about 110 are in orbit.

Rakuten and AST SpaceMobile first introduced they have been working collectively greater than a 12 months in the past. On the time, the businesses hoped to start business service in Japan by late 2023 or early 2024. Rakuten Cellular defined that to check communication with BlueWalker 3, the corporate needed to apply to the Japanese authorities’s regional Tohoku Bureau of Telecommunications. The corporate sought a “Gateway Experimental Check Station” license, which it described in a press launch as equal to a cell base station. Rakuten Cellular additionally went to the Kanto Bureau of Telecommunications for a Cellular Terminal Experimental Check Station license, which it described as much like a conveyable cell base station. Each regulatory our bodies accredited the request, Rakuten Cellular famous.

With the bureaucratic paperwork out of the way in which, Rakuten Cellular stated it’ll prep a gateway earth station, the equal of a cell base station. That machine will start working in Japan’s Fukushima prefecture, to assist Rakuten take a look at and confirm direct communications between BlueWalker 3 and cell handsets working in mountainous areas on the northern Japanese island of Hokkaido. Rakuten additionally described among the important software program that AST SpaceMobile will likely be incorporating into its community to assist the trouble.

AST SpaceMobile’s service is designed to assist unmodified cell handsets. Picture by way of Rakuten and AST SpaceMobile.

“To allow testing with Rakuten Cellular and different carriers, Rakuten Symphony will present a wide range of software program from its Symworld product portfolio to AST SpaceMobile to be built-in into the corporate’s satellite tv for pc system and allow the corporate’s space-based mobile broadband community. The software program to be built-in contains Rakuten Symphony’s vRAN (virtualized Radio Entry Community) software program, OSS (Operations Assist Methods) and BSS (Enterprise Assist Methods) software program,” stated Rakuten Cellular.

Whereas AST SpaceMobile exams BlueWalker 3 with Rakuten Cellular and different telcos, different non-terrestrial networking (NTN) cell efforts proceed apace. Maybe the highest-profile but is Apple’s deployment of “Emergency SOS by 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 activate in some European nations in December. Apple developed the service with satellite tv for pc operator Globalstar, contributing practically half a billion {dollars} from its Superior Manufacturing Fund to improve Globalstar’s floor stations with custom-designed high-power antennas. In contrast to AST SpaceMobile’s proposed community, nevertheless, that service is proscribed solely to iPhone 14 fashions, which have a Qualcomm modem that helps Globalstar’s n53 band.
