2ApplicationMCVGSM Systems OnBoard Vessels (GSMOBV).
GSM Base Station onboard vessels, called v-BS.
This RIR covers the radio regulatory aspects of operation of GSMOBV in the international sea.
3Frequency band1805 - 1880 MHzTX: 1805 - 1880 MHz / RX: 1710 - 1785 MHz.

7Transmit power / Power densityMax. -80 dBm/200 kHz at ship perimeter or on open deck areas.-
8Channel access and occupation rulesAccording to comments for authorisation regime.-
9Authorisation regimeSwitzerland: License exempt.
Liechtenstein: General authorisation.		GSM 1800 v-BS may be operated onboard vessels registered in Switzerland or the Principality of Liechtenstein.
Any operation of the System within territorial sea shall comply with the following requirements:
- the System shall not be used closer than 2 NM from the baseline;
- only indoor v-BS antenna(s) shall be used between 2 and 12 NM from the baseline (3);
- DTX (4) has to be activated on the System uplink;
- the timing advance (5) value of v-BS must be set to minimum;
- all v-MS shall be controlled to use the minimum output power (5 dBm in 900 MHz and 0 dBm in 1800 MHz bands);
- Within 2-3 NM from the baseline the v-MS receiver sensitivity and the disconnection threshold (ACCMIN (6) and min RXLEV (7) level) shall be equal to or greater than -70 dBm/200 kHz;
- Within 3-12 NM from the baseline the v-MS receiver sensitivity and the disconnection threshold (ACCMIN and min RXLEV level) shall be equal to or greater than -75 dBm/200 kHz;
- the v-BS emissions measured anywhere external to the vessel (i.e. at ship perimeter or on its open deck areas) shall not exceed -80 dBm/200 kHz (assuming a 0 dBi measurement antenna gain);

Note: For information on implementation of the technical measures described in this section, see ECC Report 122.
