The Broadband Global Area Network (BGAN) is a global satellite network with telephony owned by Inmarsat using portable terminals. [1] The terminals are normally used to connect a laptop computer to broadband Internet in remote locations, although as long as line-of-sight to the satellite exists, the terminal can be used anywhere.
The GSAT-7A, with a mission life of 8 years, is also equipped with the payload of 10 Ku band transponders, [6] which offers several advantages over c-band, such more powerful satellite uplink and downlink signals, smaller antennas, and non-interference of communication signals with terrestrial microwave systems.

A high-throughput satellite (HTS) is a communications satellite which provides more throughput than a classic fixed service satellite (FSS). An HTS provides at least twice, though usually 20 times or more, [ 1 ] throughput for the same amount of allocated orbital spectrum , thus significantly reducing cost-per-bit. [ 2 ]
Syncom 2 was the first communications satellite in a geosynchronous orbit. It revolved around the Earth once per day at constant speed, but because it still had north–south motion, special equipment was needed to track it. [19] Its successor, Syncom 3, launched on 19 July 1964, was the first geostationary communications satellite. Syncom 3 ...
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.
Illustration of the WGS satellites in its two configurations, known as Block I (left) and Block II (right) The Wideband Global SATCOM system (WGS) is a high capacity United States Space Force satellite communications system planned for use in partnership by the United States Department of Defense (DoD), Canadian Department of National Defence (DND) and the Australian Department of Defence.

SES-10, is a geostationary communications satellite awarded in February 2014, owned and operated by SES and designed and manufactured by Airbus Defence and Space on the Eurostar-3000 satellite bus. [4] [5] It is positioned at the 67° West position thanks to an agreement with the Andean Community to use the Simón Bolivar-2 satellite network.
