Abstract

Aspects of the technology involve a satellite communication system comprising a base station that communicates with standard compliant user equipment (UE) via a satellite having a field of view. The base station includes a processing device configured to generate a satellite beam at the satellite having a first transmission protocol or a second transmission protocol. The processing device is able to selectively switch between the first transmission protocol and the second transmission protocol based on an actual amount of data traffic by the UE in the field of view or an expected amount of data traffic by the UE in the field of view.
