Electronic Communications Citation and commencement 1 These Regulations may be cited as the Wireless Telegraphy (Mobile Communication Services on Board Ships) (Exemption) Regulations 2011 and shall come into force on 10th March 2011. Interpretation 2 In these Regulations— “apparatus” means wireless telegraphy apparatus; “baseline” has the meaning given in regulation 4(2)(b); “ dBi ” means decibels of power referenced to the gain of an isotrope antenna; “ dBm ” means decibels of power referenced to one milliWatt; “ ETSI ” means the European Telecommunications Standards Institute; “ GSM system” means an electronic communications network, that complies with the GSM standard EN 301 511 published by ETSI ; “ kHz ” means kilohertz; “ MHz ” means megahertz; “mobile communication services on board ships” means electronic communications services provided to enable persons on board a ship to communicate via public communication networks using a GSM system without establishing direct connections with land-based mobile networks; “ship base transceiver station” means a mobile pico-cell located on a ship supporting GSM services in the 900 MHz band or in the 1800 MHz band; “the 900 MHz band” means the 880-915 MHz frequency band (for the uplink from the apparatus to the ship base transceiver station) and the 925-960 MHz frequency band (for the downlink from the ship base transceiver station to the apparatus); and “the 1800 MHz band” means the 1710-1785 MHz frequency band (for the uplink from the apparatus to the ship base transceiver station) and the 1805-1880 MHz frequency band (for the downlink from the ship base transceiver station to the apparatus). Exemption 3 The use of any apparatus on board a ship which is— a registered in the United Kingdom, the Isle of Man, or any of the Channel Islands; and b within the limits of the British Islands and the territorial waters adjacent thereto, or, for the time being, beyond the British Islands and the territorial waters adjacent thereto; is hereby exempt from the provisions of section 8(1) of the Wireless Telegraphy Act 2006 where the terms, provisions and limitations in regulation 4 are met. Terms, provisions and limitations 4 1 The apparatus shall operate in the 900 MHz band and the 1800 MHz band. 2 The apparatus shall be used— a only for mobile communication services on board ships; and b only when the ship is two nautical miles or more from the baseline for measuring the breadth of the territorial waters under the United Nations Convention on the Law of the Sea (“baseline”). 3 When controlled by a ship base transceiver station, the apparatus shall operate with a maximum radiated output power which is no greater than— i 5 dBm in the 900 MHz band; and ii 0 dBm in the 1800 MHz band. 4 The apparatus shall connect directly to a ship base transceiver station which— a only uses indoor antennas between two and twelve nautical miles from the baseline; and b operates such that there is a maximum power density in external areas of the ship of –80 dBm per 200 kHz with reference to a 0 dBi measurement antenna gain. 5 The apparatus must form part of a GSM system which mitigates interference using the techniques in paragraph (6) or other techniques which provide at least an equivalent mitigation of interference. 6 The techniques referred to in paragraph (5) are— a the receiver sensitivity and disconnection threshold (as described in the GSM standards TS 144 008 and TS 144 018 published by ETSI) of the apparatus when used on board a ship is— i between two and three nautical miles from the baseline equal to or higher than –70 dBm per 200 kHz; and ii between three and twelve nautical miles from the baseline equal to or higher than –75 dBm per 200 kHz; b discontinuous transmission (as described in the GSM standard TS 144 008 published by ETSI) is activated in the uplink from the apparatus to the ship base transceiver station; and c the timing advance (as described in the GSM standard TS 144 018 published by ETSI) is set to the minimum. 7 The apparatus shall not cause or contribute to undue interference to any wireless telegraphy.
