How Amazon Leo plans to connect mobile devices from space - About Amazon

What the report says

About Amazon reported that Amazon Leo has asked the U.S. Federal Communications Commission for approval to launch and operate a direct-to-device satellite system made up of as many as 5,105 low Earth orbit satellites. The proposed network is intended to connect compatible smartphones and other mobile devices from space, supporting voice, data, messaging and emergency communications in places beyond the reach of cell towers. Amazon said deployment would begin in 2028.

The filing follows Amazon’s April definitive merger agreement with Globalstar, under which Amazon would acquire Globalstar satellite operations, infrastructure and assets, including mobile satellite services spectrum licenses. The planned Amazon Leo Direct-to-Device system would use Globalstar spectrum and operate alongside Leo’s existing and planned broadband satellite systems, as well as Globalstar constellations. Amazon said it will work with mobile network operators and other partners to extend service globally.

According to the company, the satellites would be placed in five orbital shells between 510 and 580 kilometers in altitude, with inclinations designed to serve mid-latitude, high-latitude and near-polar regions. The system would use L-band and S-band links for devices, and Ka-band and V-band links to connect satellites with Amazon ground stations. Amazon also described onboard signal processing, laser links between satellites, digital beamforming and beam-hopping as tools to improve capacity and reduce interference.

The plan matters because direct-to-device satellite service is becoming a major focus for telecom and technology companies seeking to fill coverage gaps, support emergency communications and connect remote operations. About Amazon said Leo already has more than 390 satellites in orbit for its first-generation broadband network and has announced partnerships including Apple, Vodafone, DirecTV, Herotel and Australia’s National Broadband Network.
