[F1ANNEX U.K. Conditions to be met by a system providing MCV services in the territorial seas of the Member States of the European Union, in order to avoid harmful interference to land-based mobile networks

Textual Amendments

(1) Conditions to be met by GSM systems operating in the 900 MHz band and 1 800 MHz band providing MCV services in the territorial seas of the Member States, in order to avoid harmful interference to land-based mobile networks U.K.

The following conditions shall apply:

(a)

the system providing MCV services shall not be used closer than 2 nautical miles (1) from the baseline, as defined in the United Nations Convention on the Law of the Sea;

(b)

only indoor vessel-BS antenna(s) shall be used between 2 and 12 nautical miles from the baseline;

(c)

limits to be set for mobile terminals when used on board vessel and for vessel-BS:

a

ACCMIN (RX_LEV_ACCESS_MIN); as described in GSM standard ETSI TS 144 018.

b

RXLEV (RXLEV-FULL-SERVING-CELL); as described in GSM standard ETSI TS 148 008.

c

Discontinuous transmission, or DTX; as described in GSM standard ETSI TS 148 008.

d

Timing advance; as described in GSM standard ETSI TS 144 018.]

Parameter Description
Transmit power/power density

For mobile terminals used on board vessels and controlled by the vessel-BS in the 900 MHz band, maximum radiated output power:

5 dBm

For mobile terminals used on board vessels and controlled by the vessel-BS in the 1 800 MHz band, maximum radiated output power:

0 dBm

For base stations on board vessels, the maximum power density measured in external areas of the vessel, with reference to a 0 dBi measurement antenna gain:

– 80 dBm/200 kHz

Channel access and occupation rules

Techniques to mitigate interference that provide at least equivalent performance to the following mitigation factors based on GSM standards shall be used:

  • between 2 and 3 nautical miles from the baseline, the receiver sensitivity and the disconnection threshold (ACCMIN a and min RXLEV b level) of the mobile terminal used on board vessel shall be equal to or higher than – 70 dBm/200 kHz and between 3 and 12 nautical miles from the baseline equal to or higher than – 75 dBm/200 kHz,

  • discontinuous transmission c shall be activated in the MCV system uplink direction,

  • the timing advance d value of the vessel-BS shall be set to the minimum.
