SpaceX, Elon Musk’s company that develops aerospace technology and has, among other things, a global satellite Internet network, was announced yesterday afternoon. Satellite 5G. Agreement with American telephone company T-Mobile to provide, that is, without the need for nearby antennas for service. Strictly speaking, satellites would act as orbital antennas rather than being located on the ground. With this you will be able to install signals in rural or hilly areas.
will use the system starlink, SpaceX’s network of low-orbiting satellites (the one that generates the “trains of satellites” that are visible in the night sky when they are released into orbit), and offering connectivity to most rural areas of the United States Including very remote areas: having a view of the sky will suffice to receive a signal. It will also bring connectivity to Tesla cars.
service Will go into operation in the United States next year Once some regulatory and technical issues are resolved, and a new generation (v2) of satellites developed by Starlink are in orbit. And it won’t require space equipment, on the part of the user: it will transmit in the traditional 5G frequencies used by modern phones. In that it differs from satellite Internet service offered by SpaceX, which requires an antenna; This allows you a high speed service.
Via Twitter, Elon Musk announced that the new version of SpaceX, capable of connecting directly to phones, will be available to the rest of the world later, but it will not be high bandwidth for now, but 2 to 4 will be limited to Megabits per cell: This will work for sending text messages or making calls, but not anymore, Once it’s done, coverage will be global: in the middle of a mountain, in a desert or at sea.
As stated in the Starlink statement, 90 percent of the Earth’s surface has no telephone coverage of any kind. This includes, of course, the seas, deserts and Antarctica: current networks are limited to inhabited areas or where sufficient numbers of people move to justify the installation of a telephone antenna. Satellite 5G aims to change that. minor; At the moment it is not used for watching Netflix, but it has to be connected anywhere.
Declaration comes after approval 5G NTN Standard, which accurately considers the provision of 5G connectivity from Aakash. Starlink is not the only telecommunications company making such plans: the idea of using low orbit satellites (such as those used by Starlink, although this is far from the only one; they are in the 200 to 2000 km high band). use, approx) like 4G or 5G antennas are in the industry.
The first test concept was Google’s Loon balloons, which carry a 4G antenna to provide coverage from the stratosphere (25 km high) in rural areas (where the antenna installation is not profitable due to its small number of users) or in areas where the slope of the terrain makes it difficult to provide this mobile telephony service. Having nothing between the cell phone and the antenna facilitates connectivity and expands the coverage area.
In July this year, Ericsson, Qualcomm and Thales confirm they will conduct first tests next year To offer 5G from space. The initial tests will be conducted in a simulated space environment in France, where most of the European space industry is located.
In 2021, rumors intensified that iPhone 13 will have satellite connectivity provided by Globalstar: That company announced that it would offer Satellite 5G from a band (N53) that is present in the modems used by the iPhone 13 (among other phones), something that didn’t happen then, but it will be available next. The year will be with Starlink. Satellite
Perhaps the most ambitious design is that of AST Spacemobile, a company that wants to offer satellite mobile connectivity using low-orbit satellites (700 km high) with multiple antennas in a one-of-a-kind 65 square meter drop-down panel. . it will allow you Provide 4G and 5G service (affiliated with Nokia) to multiple users at once Over a vast terrain (about 2 times the entire surface of Argentina for each satellite): the first prototype, Bluewalker 3, arrived at Cape Canaveral this month, and awaits launch into space; The company believes that with 200 of these satellites it can provide connectivity across the planet, and use standard frequencies (that is, without the need for additional equipment).
the clear advantage with which he runs Of course, Starlink is that it already has a network of thousands of satellites operating around the world, Satellite is dedicated to the provision of Internet, so activating your global mobile phone service will depend only on the agreements you have with different companies in each country. It will soon have competition: Amazon already has more than 80 launches scheduled to put its Kuiper network into orbit, with plans for more than 3,200 satellites; And OneWeb, an industry leader, already has 428 of its 628 satellites in orbit, announcing in July that it would merge with another network, Eutelsat. Meanwhile, Starlink already has 2,800 operational satellites in orbit. It aims to have 4,000 operations.
