(ii) attached to fixed infrastructure;

(iii) attached to a fixed outdoor antenna; or

(iv) attached to, or used in, an automotive vehicle or a railway vehicle.

(3) The ultra-wideband equipment must not cause or contribute to undue interference to other users of the electromagnetic spectrum.

(4) The ultra-wideband equipment must—

(a) emit transmissions which are in accordance with the condition in regulation 6; or

(b) operate using mitigation techniques described in regulation 7 to reduce interference to other users of the electromagnetic spectrum.

Transmission limits

(a) in frequencies up to 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. density no greater than -50.0 dBm or the equivalent transmission level;

(b) in the frequency band 1.6 GHz to 2.7 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. density no greater than -45.0 dBm or the equivalent transmission level;

(c) in the frequency band 2.7 GHz to 3.4 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. density no greater than -36.0 dBm or the equivalent transmission level;

(d) in the frequency band 3.4 GHz to 3.8 GHz when measured in any direction have—

(i) a maximum mean e.i.r.p. density no greater than -80.0 dBm/MHz; and

(ii) a maximum peak e.i.r.p. density no greater than -40.0 dBm or the equivalent transmission level;

(e) in the frequency band 3.8 GHz to 4.2 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. density no greater than -30.0 dBm or the equivalent transmission level;

(f) in the frequency band 4.2 GHz to 4.8 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. density no greater than 0.0 dBm or the equivalent transmission level;

(g) in the frequency band 4.8 GHz to 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. density no greater than -30.0 dBm or the equivalent transmission level;

(h) in the frequency band 6.0 GHz to 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. density no greater than 0.0 dBm or the equivalent transmission level;

(i) in the frequency band 8.5 GHz to 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. density no greater than -25.0 dBm or the equivalent transmission level; and

(j) in frequency bands 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. density no greater than -45.0 dBm or the equivalent transmission level.

Mitigation techniques

7.—(1) The mitigation techniques referred to in regulation 5(4)(b) are—

(a) techniques for mitigating interference described in harmonised standards for ultra-wideband equipment whose reference numbers have been published in the Official Journal of the European Union under Article 5 of Council Directive 1999/5/EC on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity(1) (“harmonised standards”); or

(b) techniques for mitigating interference which achieve at least an equivalent level of protection from interference to other users of the electromagnetic spectrum as that provided by the condition in regulation 6.

(2) The techniques that may be used under regulation 7(1)(b) for equipment operating in the frequency band 3.1 GHz to 4.8 GHz include a low duty cycle mitigation technique which results in transmissions which—

(a) when measured in any direction, have a maximum mean e.i.r.p. density no greater than

-41.3 dBm/MHz;

(b) do not exceed five milliseconds in duration;

(c) for any second, the sum of all transmitted signals is less than 5% of that second;

(d) for any hour, the sum of all transmitted signals is less than 0.5% of that hour; and

(e) have a maximum peak e.i.r.p. density no greater than 0.0 dBm or the equivalent transmission level.

(3) The techniques that may be used under regulation 7(1)(b) also include, for equipment operating in the frequency band 3.1 GHz to 4.8 GHz or in the frequency band 8.5 GHz to 9.0 GHz, a technique for detecting other transmissions and avoiding interference with those transmissions (described in harmonised standards) which results in transmissions which—

(a) when measured in any direction, have a maximum mean e.i.r.p. density no greater than

-41.3 dBm/MHz; and

(b) have a maximum peak e.i.r.p density no greater than 0.0 dBm or the equivalent transmission level.
