Iridium Communications satellite phones use frequencies between 1616 and 1626.5 MHz [4] to communicate with the satellites. Iridium Communications 2-way messaging service Snapdragon Satellite will utilize frequencies in the L Band as well. Inmarsat and Ligado Networks (formerly LightSquared) terminals use frequencies between 1525 and 1646.5 MHz.
Streaming is a service that guarantees the delivery of data. In this service, a terminal requests a specific bandwidth (currently available in 8, 16, 32, 64, 128, or 256 kbit/s), and if the current spot beam has sufficient resources, the requested bandwidth is allocated to the terminal.
Most commercial voice and some data mobile satellite services are provided by systems operating in the L-band by Iridium, Inmarsat, Globalstar and Thuraya.The L-band spectrum allocated for MSS is between 1.5 and 2.5 GHz, with the upper portion often referred to as the S-band.
Advanced Land Observing Satellite 4 (ALOS-4), also called Daichi 4 (daichi is a Japanese word meaning "great land"), is a 3,000 kg (6,600 lb) Japanese L-band synthetic-aperture radar (SAR) satellite that was launched on July 1, 2024.
The Iridium satellite constellation provides L band voice and data information coverage to satellite phones, satellite messenger communication devices and integrated transceivers. Iridium Communications owns and operates the constellation , additionally selling equipment and access to its services.
