Up until now, broadband services have mainly been provided using fixed (VDSL or optical) or mobile (3G or LTE) networks. However, satellite networks are now becoming able to provide broadband services of similar bandwidth and response times to those from terrestrial networks, especially with the introduction of new hybrid satellite networks where alternative paths can be selected depending on the bandwidth and response times required. It is therefore useful to be able to assess the energy efficiency of satellite networks and compare this on an equivalent basis to the energyefficiency of terrestrial networks.
Energy efficiency is also a growing concern in the design of satellite networks and there are increasing efforts to minimize the energy consumption of SatCom systems, especially in the ground segment where most terminals have been designed to operate on an always-on basis. By carrying out an assessment of the energy efficiency of a satellite network, the subsystems and components that have the most impact can be identified and attention paid to reducing their energy consumption. In particular, given the relatively large numbers of satellite terminals in operation, theirimpact can be identified compared with that of the other subsystems and appropriate measures taken to improve their energy efficiency.
