The Wireless Telegraphy (Mobile Communication Services on Ships) (Exemption) Regulations 2017

Terms, provisions and limitations

5.—(1) The apparatus must only operate—

(a)where it forms part of a GSM system, in the 900 MHz band or the 1800 MHz band;

(b)where it forms part of a LTE system, in the 1800 MHz band or the 2600 MHz band; and

(c)where it forms part of an UMTS system, in the 1900/2100 MHz band.

(2) The apparatus must only be used—

(a)for mobile communication services on board ships;

(b)where it forms part of a GSM system or an UMTS system, when the ship is two nautical miles or more from the baseline; and

(c)where it forms part of a LTE system, when the ship is four nautical miles or more from the baseline.

(3) When controlled by a ship base transceiver station, the apparatus must operate with a maximum radiated output power which is no greater than—

(a)where it forms part of a GSM system—

(i)5 dBm in the 900 MHz band; and

(ii)0 dBm in the 1800 MHz band;

(b)where it forms part of a LTE system, 0 dBm in the 1800 MHz band and in the 2600 MHz band; and

(c)where it forms part of an UMTS system, 0 dBm for each 5 MHz in the 1900/2100 MHz band.

(4) The apparatus must connect directly to a ship base transceiver station that complies with the requirements set out in paragraphs (5) to (7).

(5) Where the apparatus forms part of a GSM system, the requirements referred to in paragraph (4) are—

(a)the ship base transceiver station must only use indoor antennas when the ship is between two and twelve nautical miles from the baseline;

(b)the ship base transceiver station must operate such that there is a maximum power density in external areas of the ship of –80 dBm for each 200 kHz with reference to a 0 dBi measurement antenna gain;

(c)the ship base transceiver station must mitigate interference using the following techniques or other techniques which provide at least an equivalent mitigation of interference—

(i)the receiver sensitivity and disconnection threshold (as described in the GSM standards TS 144 018(1) and TS 148 008(2) published by ETSI) of the apparatus is—

(aa)when the ship is between two and three nautical miles from the baseline, equal to or higher than –70 dBm for each 200 kHz; and

(bb)when the ship is between three and twelve nautical miles from the baseline, equal to or higher than –75 dBm for each 200 kHz;

(ii)discontinuous transmission (as described in the GSM standard TS 148 008 published by ETSI) is activated in the uplink from the apparatus to the ship base transceiver station; and

(iii)the timing advance (as described in the GSM standard TS 144 018 published by ETSI) is set to the minimum.

(6) Where the apparatus forms part of a LTE system, the requirements referred to in paragraph (4) are—

(a)the ship base transceiver station must only use indoor antennas when the ship is between four and twelve nautical miles from the baseline;

(b)the ship base transceiver station must only use bandwidth which is no greater than 5 MHz (duplex) for each of the 1800 MHz band or the 2600 MHz band;

(c)the ship base transceiver station must operate such that—

(i)its emissions on board the ship’s deck must be equal to or less than –98 dBm for each 5 MHz;

(ii)when the ship is between four and twelve nautical miles from the baseline, the quality criteria are equal to or higher than –83 dBm for each 5 MHz;

(iii)the selection timer is set to 10 minutes;

(iv)the timing advance parameter is set according to a cell range for the distributed antenna system that is equal to 400 metres;

(v)the user inactivity release timer is set to 2 seconds; and

(vi)its carrier centre frequency must not be aligned with electronic communications networks based on land.

(7) Where the apparatus forms part of a UMTS system, the requirements referred to in paragraph (4) are—

(a)the ship base transceiver station must only use indoor antennas when the ship is between two and twelve nautical miles from the baseline;

(b)the ship base transceiver station must only use bandwidth which is no greater than 5 MHz (duplex);

(c)the ship base transceiver station must operate such that—

(i)its emissions on board the ship’s deck must be equal to or less than –102 dBm for each 5 MHz;

(ii)when the ship is between two and twelve nautical miles from the baseline, the quality criteria are equal to or higher than –87 dBm for each 5 MHz;

(iii)the selection timer is set to 10 minutes;

(iv)the timing advance parameter is set according to a cell range for the distributed antenna system that is equal to 600 metres;

(v)the user inactivity release timer is set to 2 seconds; and

(vi)its carrier centre frequency must not be aligned with electronic communications networks based on land.

(8) The apparatus must not cause or contribute to undue interference to any wireless telegraphy.
