electronic communications Citation and commencement 1 These Regulations may be cited as the Wireless Telegraphy (Ultra-Wideband Equipment) (Exemption) Regulations 2007 and shall come into force on 13th August 2007. Interpretation 2 In these Regulations— “ automotive vehicle ” has the meaning given for “vehicle” by Article 2 of Council Directive 70/156/EEC on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers , as amended ; “dBm” means decibel milliWatt; “dBm/MHz” means decibel per milliWatt; “e.i.r.p.” means equivalent isotropic radiated power; “ equivalent transmission level ” means the peak level of transmission contained within a bandwidth which is other than 50 MHz, centred on the frequency at which the highest mean radiated power occurs, and which is the relevant maximum peak e.i.r.p. scaled down by a factor of 20log(50/x)dB, where “x” is the other bandwidth expressed in MHz; “GHz” means gigahertz; “ indoors ” means inside buildings or places in which the shielding will typically provide the necessary attenuation to protect wireless telegraphy against harmful interference; “mean e.i.r.p. density” means the mean e.i.r.p. measured with a 1 MHz resolution bandwidth, a root-mean-square detector and an averaging time of one millisecond or less; “MHz” means megahertz; “peak e.i.r.p.” means the peak e.i.r.p. contained within a 50 MHz bandwidth centred on the frequency at which the highest mean radiated power occurs; “ railway vehicle ” has the meaning given by Article 3 of EC Regulation 91/2003 of the European Parliament and of the Council of 16 December 2002 on rail transport statistics , as amended ; “ ultra-wideband equipment ” means a wireless telegraphy station or wireless telegraphy apparatus incorporating, as an integral part or as an accessory, technology for short-range radiocommunication involving the intentional generation and transmission of radio-frequency energy that spreads over a frequency range wider than 50 MHz, which may overlap several frequency bands allocated to wireless telegraphy. Exemption 3 The establishment, installation or use of ultra-wideband equipment complying with the terms, provisions and limitations set out in regulation 4 is hereby exempt from the provisions of section 8(1) of the Act. Terms, provisions and limitations 4 1 The exemption provided for in regulation 3 shall be limited to ultra-wideband equipment which satisfies the conditions set out in paragraphs (2) to (5) of this regulation. 2 The equipment is used— a indoors; or b other than indoors provided it is not attached to: i a fixed installation; ii a fixed infrastructure; iii a fixed outdoor antenna; or iv an automotive vehicle or railway vehicle. 3 The equipment does not cause or contribute to undue interference to any wireless telegraphy. 4 The equipment only emits transmissions at frequencies up to and including 3.4 GHz or at frequencies above 4.8 GHz which: a at frequencies below and up to and including 1.6 GHz when measured in any direction have: i a maximum mean e.i.r.p. density no greater than -90.0 dBm/MHz; and ii a maximum peak e.i.r.p. no greater than -50.0 dBm or the equivalent transmission level; b at frequencies between 1.6 GHz and up to and including 3.4 GHz when measured in any direction have: i a maximum mean e.i.r.p. density no greater than -85.0 dBm/MHz; and ii a maximum peak e.i.r.p. no greater than -45.0 dBm or the equivalent transmission level; c at frequencies between 4.8 GHz and up to and including 6.0 GHz when measured in any direction have: i a maximum mean e.i.r.p. density no greater than -70.0 dBm/MHz; and ii a maximum peak e.i.r.p. no greater than -30.0 dBm or the equivalent transmission level; d at frequencies between 6.0 GHz and up to and including 8.5 GHz when measured in any direction have: i a maximum mean e.i.r.p. density no greater than -41.3 dBm/MHz; and ii a maximum peak e.i.r.p. no greater than 0.0 dBm or the equivalent transmission level; e at frequencies between 8.5 GHz and up to and including 10.6 GHz when measured in any direction have: i a maximum mean e.i.r.p. density no greater than -65.0 dBm/MHz; and ii a maximum peak e.i.r.p. no greater than -25.0 dBm or the equivalent transmission level; f at frequencies above 10.6 GHz when measured in any direction have: i a maximum mean e.i.r.p. density no greater than -85.0 dBm/MHz; and ii a maximum peak e.i.r.p. no greater than -45.0 dBm or the equivalent transmission level. 5 The equipment only emits transmissions at frequencies between 3.4 GHz and up to and including 4.8 GHz which: a at frequencies between: i 3.4 GHz and up to and including 3.8 GHz when measured in any direction have: aa a maximum mean e.i.r.p. density no greater than -85.0 dBm/MHz; and bb a maximum peak e.i.r.p. no greater than -45.0 dBm or the equivalent transmission level; ii 3.8 GHz and up to and including 4.2 GHz when measured in any direction have: aa a maximum mean e.i.r.p. density no greater than -70.0 dBm/MHz; and bb a maximum peak e.i.r.p. no greater than -30.0 dBm or the equivalent transmission level; iii 4.2 GHz and up to and including 4.8 GHz when measured in any direction have: aa a maximum mean e.i.r.p. density no greater than -41.3 dBm/MHz; and bb a maximum peak e.i.r.p. no greater than 0.0 dBm or the equivalent transmission level; or b at frequencies between 3.4 GHz and up to and including 4.8 GHz when measured in any direction have a maximum mean e.i.r.p. density no greater than -41.3 dBm/MHz provided a low duty cycle applies such that: i the duration of each transmission does not exceed five milliseconds; ii the sum of all transmitted signals in any second is less than 5% of that second; iii the sum of all transmitted signals in any hour is less than 0.5% of that hour; and iv the maximum peak e.i.r.p. is no greater than 0.0 dBm or the equivalent transmission level.
