Sistemet dhe Stacionet Satelitore në Tokë (SES); EN i harmonizuar për Terminale me Hapje Shumë të Vogël (VSAT); Stacionet satelitore në tokë vetëm për transmetim, transmetim/marrje ose vetëm marrës që punojnë në bandën e frekuencave 11/12/14 GHz që mbulon kërkesat thelbësore nën artikullin 3.2 të direktivës R&TTE

Satellite Earth Stations and Systems (SES); Harmonized EN for Very Small Aperture Terminal (VSAT); Transmit-only, transmit/receive or receive-only satellite earth stations operating in the 11/12/14 GHz frequency bands covering essential requirements under article 3.2 of the R&TTE directive

Scope

The present document applies to Very Small Aperture Terminals (VSATs) which have the following characteristics:
• The VSAT are operating in one or more frequency ranges in the part of the following bands allocated
exclusively to the Fixed Satellite Services (FSS):
- 14,00 GHz to 14,25 GHz (earth-to-space);
- 12,50 GHz to 12,75 GHz (space-to-earth);
or in the shared parts of the following bands, allocated to the FSS and Fixed Services (FS):
- 14,25 GHz to 14,50 GHz (earth-to-space);
- 10,70 GHz to 11,70 GHz (space-to-earth).
• The VSAT use linear polarization.
• The VSAT operate 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 3,8 m, or equivalent corresponding aperture.
• The VSAT are either:
- transmit only VSAT: designed for transmission only of radio-communications signals in any of the frequency
bands (earth-space) specified above; or
- transmit and receive VSAT: designed for transmission and reception of radio-communications signals in any
of the frequency bands specified above; or
- receive only VSAT: designed for reception only of radio-communications signals in any of the frequency
bands (space-earth) specified above.
• The VSAT are designed usually for unattended operation.
• The VSAT are 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 VSAT are 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 1999/5/EC [1] (R&TTE Directive) Article 3.2,
which states that "… radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as 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 Directive 1999/5/EC [1] (R&TTE Directive) may apply to equipment within the
scope of the present document.
