ANNEX 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

The following conditions shall be met:

1.

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;

2.

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

3.

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.

ParameterDescription
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 (ACCMINa and min RXLEVb 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 transmissionc shall be activated in the MCV system uplink direction,

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

One nautical mile = 1 852 metres.
