Satellite Earth Stations and Systems (SES); Fixed and in-motion Wide Band Earth Stations communicating with non-geostationary satellite systems (WBES) in the 11 GHz to 14 GHz frequency bands; Harmonised Standard for access to radio spectrum (ETSI EN 303 981 V1.2.1 (2021-04))
The present document specifies technical characteristics and methods of measurements for fixed and in-motion Earth
Stations communicating with non-geostationary satellite systems (WBES) in the 11 GHz to 14 GHz FSS frequency
bands, which have the following characteristics:
• The WBES is further defined as one of two classes of Earth stations, class A and class B. The clauses in the
present document apply to both classes unless separately delineated.
• The WBES is designed for both in-motion and stationary operation.
• The WBES operates in-motion on various platforms such as trains, maritime vessels, aircraft and other
vehicles and, therefore, may be subject to occasional disturbances and interruptions in the satellite link.
• The WBES is operating as part of a satellite system used for the provision of broadband communications.
• The WBES is comprised of all the equipment, electrical and mechanical, from the antenna itself to the
interface with other communications equipment on a mobile platform.
• The WBES comprises one or more emitters and the system overview as given in figure 1 should be interpreted
accordingly.
