3	Frequency band	925 - 960 MHz	TX: 925 - 960 MHz / RX: 880 - 915 MHz.
4	Channelling	200 kHz	-
5	Modulation / Occupied bandwidth	200KG7WDT	GMSK (Gaussian Minimum Shift Keying)
6	Direction / Separation	45 MHz	-
7	Transmit power / Power density	Max. -80 dBm/200 kHz at ship perimeter or on open deck areas.	-
8	Channel access and occupation rules	According to comments for authorisation regime.	-
9	Authorisation regime	Switzerland: License exempt. Liechtenstein: General authorisation.	GSM 900 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. ------------------------------- 3) See Background section of ECC/DEC/(08)08. 4) DTX (discontinuous transmission, as described in GSM standard 3GPP TS 148.008) 5) Timing advance (as described in GSM standard 3GPP TS 144.018) 6) ACCMIN (RX_LEV_ACCESS_MIN, as described in GSM standard 3GPP TS 144.018) 7) RXLEV (RXLEV-FULL-SERVING-CELL, as described in GSM standard 3GPP TS 148.008)
