What is beam switching?
Method of obtaining more accurately the bearing or elevation of an object by comparing the signals received when the beam is in directions differing slightly in bearing or elevation; when these signals are equal, the object lies midway between the beam axes. Also known as lobe switching.
What is switching in satellite communication?
A multi-beam satellite switching system employs onboard switching for the purpose of increasing the up path and down path antenna gains. A multiplicity of up path antenna beams and of down path antenna beams (not necessarily the same number of each direction) are provided by the system.
What are beams in satellite?
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.
What is a beam switching antenna?
A beam-switching antenna consists of generating a multiplicity of juxtaposed beam (generated by. an array) whose output may be switched to a receiver or a bank of receiver [1].
Why beamforming is used?
Benefits of beamforming Higher signal quality reaches the receiving device, which increases the coverage capacity of the cell tower or base station. There are faster information transfers and fewer errors. Signal interference between devices is avoided since signals are only broadcast where needed.
What is beam selection?
Beam selection is a notable issue for recent wireless communications. A conventional single beam selection (SBS) concept is utilized to minimize the number of necessary radio frequency chains in millimeter-wave (mmWave) multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) systems.
What are spot beams used for?
A communications satellite signal that transmits to a pinpointed geographic area on earth. Spot beam technology allows different data to be sent to different locations using the same carrier frequencies.
What is a beam in beamforming?
Beamforming is a type of radio frequency (RF) management in which a wireless signal is directed toward a specific receiving device. Beamforming is applied to numerous technologies, including wireless communications, acoustics, radar and sonar.
How beamforming is done?
The beamforming technique involves sending the pulse from each projector at slightly different times (the projector closest to the ship last), so that every pulse hits the ship at exactly the same time, producing the effect of a single strong pulse from a single powerful projector.
How do I perform beam switching?
Beam Switching 1 Select the most optimal beam for each terminal automatically 2 Minimize service outage during beam switches 3 Set priorities to meet service level agreements (SLAs) on various parameters 4 Ensure compatibility between the antenna controller unit and the satellite 5 Streamline service activation and configuration More
What is beam switchover and how does it work?
Beam switchover requires both the ability of the modem to determine when and to which beam to switch to as well as communication with the COTM antenna. ST Engineering iDirect has developed a number features and partnered with a number of antenna manufacturers to optimize this process.
How do I join a new beam on my modem?
When joining a new beam, the terminal must re-point its antenna and the modem must tune to a new outroute. Selection of the new beam can be performed manually by using remote modem console commands or automatically using ABS on Evolution and Velocity and AIBS on Dialog.
What is a beam switch API?
Beam switch APIs enable a terminal operator to use customer-provided beam switch logic in place of the built-in ABS logic. Geoscope Regions are used by a service provider to guarantee a defined level of service within a specific geographic area and in Velocity, a geoscope region may be specified as a group of beams or a group of service areas.
