Dynamic Beamforming for High-Value Mobile Telecommunications Applications
A paper about digital beamforming found that this architecture enables a power, frequency and beam steering flexibility that meets the requirements of a wide range of user terminal distributions. The study found that user terminals can vary in shape, size, location and conductivity which can makebeamforming difficult. However, the study found that by matching the distributions of user terminals with an active array antenna, it is possible to provide a beamformed signal similar to the users desired signal. Digital beamforming requires someone to monitor the beams and adjust the signals so they are close to the users they are serving. This may be done through a remote control or cyber-telemetryenabled system. This system will enable less expensive satellites to deliver telecommunications services to more populated areas while providing redundancy for satellites in case one becomes unavailable.
