Exemption 4 The use of any apparatus on board an aircraft which is— a registered in the British Islands; and b flying over 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 5 are met. Terms, provisions and limitations 5 1 The apparatus must comply with the standards published by ETSI which are referred to in paragraph (2). 2 The standards referred to in paragraph (1) are— a for GSM apparatus, the GSM standard EN 301 511 ; b for UMTS apparatus, the UMTS standards— i EN 301 908–1 ; and ii EN 301 908–2 ; c for LTE apparatus, the LTE standards— i EN 301 908–1; and ii EN 301 908–13 . 3 The apparatus must only operate in the 1800 MHz band or the 2100 MHz band. 4 The apparatus must only be used— a for mobile communication services on aircraft; b when the aircraft is three thousand metres or more above the ground; c where the following operational requirements are met— i the aircraft BTS, while in operation, limits the transmission power of all GSM apparatus to a nominal value of 0 dBm/200 kHz at all stages of communication, including initial access; ii the aircraft BTS, while in operation, limits the transmission power of all LTE apparatus in the 1800 MHz band to a nominal value of 5 dBm/5 MHz at all stages of communication; or iii the aircraft BTS, while in operation, limits the transmission power of all UMTS apparatus in the 2100 MHz band to a nominal value of -6 dBm/3.84 MHz at all stages of communication and limits the number of users to no more than twenty; or d where the e.i.r.p. outside the aircraft emanating from the apparatus transmitting in the frequency bands specified in the headings of Columns 2 to 4 of Table 1 of the Schedule does not, at each of the heights above ground specified in Column 1 of that Table, exceed the relevant value specified in Columns 2, 3 or 4 of that Table. 5 The apparatus must not cause or contribute to any undue interference to any wireless telegraphy. 6 The apparatus must connect directly to a relevant network that complies with the requirements set out in paragraph (7). 7 The requirements referred to in paragraph (6) are— a the apparatus used in the relevant network must be prevented from operating on the frequency bands 925–960 MHz and 2110–2170 MHz to register with UMTS networks by the installation of— i shielding in the aircraft’s fuselage that prevents signals from entering and leaving the fuselage; or ii a network control unit; b the relevant network must operate such that the total e.i.r.p. of the network control unit outside the aircraft for the frequency band 925–960 MHz does not, at each height above ground specified in Column 1 of Table 2 of the Schedule, exceed the relevant value specified in Column 2 of that Table; c the relevant network must operate such that the total e.i.r.p. of the aircraft BTS outside the aircraft for the frequency band 1805–1880 MHz does not, at each height above ground specified in Column 1 of Table 2 of the Schedule, exceed the relevant value specified in Column 3 of that Table; d the relevant network must operate such that the total e.i.r.p. of the network control unit and the aircraft BTS outside the aircraft for the frequency band 2110–2170 MHz does not, at each height above ground specified in Column 1 of Table 2 of the Schedule, exceed the relevant value specified in Column 4 of that Table; e if the network control unit also operates on one of the frequency bands specified in the heading of Columns 2 to 5 of Table 3 of the Schedule, the network control unit and the aircraft BTS must operate such that the total e.i.r.p. outside the aircraft does not, at each height above ground specified in Column 1 of that Table, and at each of those frequency bands, exceed the relevant value specified in Columns 2, 3, 4 or 5 of that Table; f the aircraft BTS must comply with the following standards published by ETSI— i the GSM standards— aa EN 301 502 ; and bb EN 302 480 ; ii the UMTS standards— aa EN 301 908–1; and bb EN 301 908–3 or EN 301 908–11 ; or iii the LTE standards— aa EN 301 908–1; and bb EN 301 908–14 or EN 301 908–15 ; and g the network control unit must comply with the standard EN 302 480 published by ETSI.
