EVS-EN 301 443 V2.1.1:2016

The present document applies to any Very Small Aperture Terminal (VSAT) which has the following characteristics:
• the VSAT is operating in one or more frequency ranges within the following bands allocated to the Fixed
Satellite Service (FSS), shared with other services, e.g. the Fixed Service (FS) and the Mobile Service (MS):
- 5,850 GHz to 7,075 GHz (earth-to-space);
- 3,400 GHz to 4,200 GHz (space-to-earth);
• the VSAT uses linear or circular polarization;
• the VSAT operates through a geostationary satellite at least 3° away from any other geostationary satellite
operating in the same frequency band and covering the same area;
• the VSAT antenna diameter does not exceed 7,3 m, or equivalent effective area;
• the VSAT is either:
- a transmit-only VSAT: designed for transmission-only of radio-communications signals in the frequency
band (earth-to-space) specified above; or
- a transmit-and-receive VSAT: designed for transmission-and-reception of radio-communications signals
in the frequency bands specified above; or
- a receive-only VSAT: designed for reception-only of radio-communications signals in the frequency
band (space-to-earth) specified above;
• the VSAT is designed usually for unattended operation;
• the VSAT is operating as part of a satellite network (e.g. star, mesh or point-to-point) used for the distribution
and/or exchange of information between users;
• the transmit-only and transmit-and-receive VSAT is controlled and monitored by a Centralized Control and
Monitoring Function (CCMF). The CCMF is outside the scope of the present document.
The present document applies to the VSAT with its ancillary equipment and its various terrestrial ports, and when
operated within the boundary limits of the operational environmental profile declared by the applicant and when
installed as required by the applicant by declaration or in the user documentation.
The present document is intended to cover the provisions of Directive 2014/53/EU (RE Directive) [6] article 3.2, which
states that "... radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio
spectrum in order to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the RE Directive [6] may apply to equipment within the scope of the present document.
