Science Fair Project Encyclopedia A spot beam, in
telecommunications parlance, is a satellite signal that is
specially concentrated in power so that it will only cover a
limited geographic area. Spot beams are used so that only earth
stations in a particular intended reception area can properly
receive the satellite signal. One notable example of the use of
spot beams is on direct broadcast satellite systems such as
DirecTV and DISH Network that deliver local broadcast television
via satellite only to viewers in the part of North America from
which those terrestrial broadcast stations originate. The
