Broadband Internet Satellite

A broadband Internet satellite is a communications satellite designed to provide high-speed Internet access to fixed or mobile users over wide geographic areas. These systems deliver IP-based data services to users who lack access to terrestrial broadband infrastructure, such as fiber, cable, or cellular networks, or who require connectivity while mobile at sea, in the air, or in remote regions.

Broadband Internet satellite systems typically operate in Ku-band and Ka-band, using high-gain spot beams, frequency re-use, and adaptive modulation and coding to achieve high aggregate capacity. User terminals employ relatively small antennas compared with traditional Earth stations, while gateway stations connect the satellite network to the terrestrial Internet backbone. End-to-end performance is influenced by satellite orbit: geostationary systems exhibit higher latency due to long propagation delay, whereas non-geostationary systems in LEO or MEO offer lower latency at the cost of increased constellation complexity.

Broadband Internet satellites are widely used for residential broadband in underserved areas, enterprise connectivity, mobile backhaul, maritime and aeronautical communications, and emergency and disaster-recovery communications.
