ETS 300 333-1994 Satellite Earth Stations and Systems (SES); Receive-Only Very Small Aperture Terminals (VSATs) Used for Data Distribution Operating in the 4 GHz Frequency Band
"This European Telecommunication Standard (ETS) provides specifications for the standardisation of the characteristics of receive-only Very Small Aperture Terminals (VSATs) operating as part of a satellite network used for the distribution of data. These VSATs have the following characteristics: - operating in the shared part of the C band allocated to the Fixed Services (FS) and to the Fixed Satellite Services (FSS)@ 3@625 to 4@200 GHz (Space-Earth); - in this frequency band circular polarisation is normally used and the system operates through satellites at 3??pacing; - designed for unattended operation; - limited to the reception of baseband digital signals; - equipped with one or several terrestrial output ports; - antenna diameter not exceeding normally 7@3 m@ or equivalent corresponding aperture. The equipment considered in this ETS comprises both the ""outdoor unit""@ usually composed of the antenna subsystem with the associated Low Noise Block (LNB)@ and the ""indoor unit"" composed of the remaining part of the communication chain@ including the cable between these two units. This ETS does not contain any requirement@ recommendation or information about the installation of the VSATs@ nor is this ETS intended to apply to VSAT network hub stations. This ETS deals with two types of specification: - specifications defined in order to protect other users of the frequency spectrum@ both satellite and terrestrial@ from unacceptable interference. In addition@ these specifications are specified for the purposes of electrical safety@ structural safety and solar radiation protection as well as protection from harmful interference; - specifications related to characteristics which contribute to the quality of reception by providing the VSAT with a minimum interference protection from other radio systems."
