Satellites systems can be used to provide high quality interactive (two-way) multimedia communications, a service known as Broadband Satellite Multimedia (BSM). BSM systems will be able to provide broadband access to the internet, addressing a mass market and covering large regions. BSM systems are a major growth area in the industry and a priority within ETSI.
Broadband satellite access networks will complement wired and wireless access systems, delivering telecommunications services into and within both homes and business. The specifications produced will help ensure that the protocols developed for terrestrial Internet Protocol (IP) networks can be used over different families of satellite systems.
Most BSM systems are expected to utilize Ku (12-18 GHz) and Ka (27-40 GHz) -bands, and to be operated with fixed terminals (Fixed Satellite Service, FSS), but these are not specific requirements.
