Spot Beam Glossary Definition

A spot beam, in telecommunications parlance, is a satellite signal that is specially concentrated in power (i.e. sent by a high-gain antenna) so that it will cover only a limited geographic area on Earth. Spot beams are used so that only earth stations in a particular intended reception area can properly receive the satellite signal.

Spot Beam is a Telecommunications satellite or microwave concept used to transmit communications through radio links, earth stations, antennas, or orbiting spacecraft.

Satellite and microwave professionals use this concept when planning links, coverage, latency, earth-station equipment, and line-of-sight communications.

Related concepts include Telecommunications, Uplink and Downlink.
