A focused antenna pattern sent to a limited geographical area. Spot beams are used by domestic satellites to deliver certain transponder signals to geographically well defined areas. Spot beams offer the potential of spectrum re-use; the same bands of frequency can be used with different spotbeams. This is particularly useful in the multimedia satellite environment.
This is a tightly focused antenna pattern that is sent to a limited geographical area, such as Hawaii or other easily definable area.
The coverage area of a satellite's broadcast on the Earth's surface. Several spot beams are sometimes used to differentiate between geographic areas.
A narrow transmission beam from a satellite antenna focused at a limited area of Earth.
Focused high-power satellite signal that covers only a small region. Outside that area the signal is undetectable, and will not interfere with other use of the same wavelength. | Previous
A spot beam is a satellite transmission that is focused on a specific area within the footprint, or broadcast area, of the satellite. Both DISH Network and DirecTV use spot beams to increase the capacity of channels they can provide, thus allowing the broadcast of more local networks.
In satellite communications systems, a narrow beam from a satellite station antenna that illuminates, with high irradiance, a limited area of the Earth by using beam (directive) antennas rather than Earth-coverage antennas.
A satellite antenna designed to direct all of the satellite's power to a relatively compact area on earth.
An antenna radiation pattern designed to serve a relatively small or isolated geographic area, usually with high gain. The radio frequency equivalent of a spotlight.
A focused antenna pattern sent to a limited geographical area. Spot beams are used by domestic satellites to deliver certain transponder signals to geographically well defined areas such as Hawaii, Alaska and Puerto Rico.
A satellite antenna beam which provides service to only a part of the satellite's total coverage area.
A spot beam is a satellite transmission that is focused on a specific area within the footprint of the satellite. To increase the capacity of channels they can provide. Both Dish Network and DirecTV started using spot beams in 2002. By using spot beams both providers can use the same frequencies in several markets simultaneously. The use of spot beams has allowed satellite TV providers to meet must carry requirements set fore by the FCC. Spot beams would be the reason you could receive your local networks at home but not when you travel more then a few hundred miles from home.
A concentrated area offering coverage within the global footprint for particular regions in the world.
A spot beam, in telecommunications parlance, is a satellite signal that is specially concentrated in power (i.e. send by a high-gain antenna) so that it will cover only 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.
