PART 7USE OF ULTRA-WIDEBAND EQUIPMENT FOR BUILDING MATERIAL ANALYSIS

Exemption

29.  The establishment, installation or use of ultra-wideband equipment complying with the terms, provisions and limitations in regulation 30 is hereby exempt from the provisions of section 8(1) of the Act.

Terms, provisions and limitations

30.—(1) The exemption provided for in regulation 29 shall apply to ultra-wideband equipment which is a building material analysis device and which complies with the requirements of paragraphs (2) to (4) of this regulation.

(2) The ultra-wideband equipment must—

(a)only have the transmitter turned on if manually operated with a non-locking switch;

(b)be used in close proximity to the material being analysed with the emissions being directed into the direction of the object of the analysis; and

(c)switch off automatically after ten seconds without any movement.

(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 only emit signals that are radiated into the air which—

(a)are kept to a minimum; and

(b)if the equipment were to be placed on a representative wall (as defined within Annex D of harmonised standard EN 302-435-1(1)) would be in accordance with the condition in regulation 31.

Transmission limits

31.  The condition referred to in regulation 30(4)(b) is that the ultra-wideband equipment only emits transmissions which—

(a)in the frequencies up to 1.215 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -85.0 dBm/MHz; and

(ii)a maximum peak power no greater than -45.0 dBm or the equivalent transmission level;

(iii)a total radiated power spectral density of -90.0 dBm/MHz;

(b)in the frequency band 1.215 GHz to 1.73 GHz when measured in any direction—

(i)have a maximum mean power spectral density —

(aa)no greater than -85.0 dBm/MHz; or

(bb)no greater than -70.0 dBm/MHz provided that a listen before talk mechanism described in harmonised standard EN 302 435-1 is used to mitigate interference to other users of the electromagnetic spectrum.

(ii)have a maximum peak power no greater than -45.0 dBm or the equivalent transmission level; and

(iii)have a total radiated power spectral density of -90.0 dBm/MHz;

(c)in the frequency band 1.73 GHz to 2.2 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -65.0 dBm/MHz;

(ii)a maximum peak power no greater than -25.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density of -70 dBm/MHz;

(d)in the frequency band 2.2 GHz to 2.5 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -50.0 dBm/MHz;

(ii)a maximum peak power no greater than -10.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density of -55 dBm/MHz;

(e)in the frequency band 2.5 GHz to 2.69 GHz when measured in any direction—

(i)have a maximum mean power spectral density —

(aa)no greater than -65.0 dBm/MHz; or

(bb)no greater than -50.0 dBm/MHz provided that a listen before talk mechanism described in harmonised standard EN 302 435-1 is used to mitigate interference to other users of the electromagnetic spectrum;

(ii)have a maximum peak power spectral density no greater than -25.0 dBm or the equivalent transmission level; and

(iii)have a total radiated power spectral density of -70.0 dBm/MHz;

(f)in the frequency band 2.69 GHz to 2.7 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -55.0 dBm/MHz;

(ii)a maximum peak power no greater than -15.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density below -65.0 dBm/MHz;

(g)in the frequency band 2.7 GHz to 3.4 GHz when measured in any direction—

(i)have a maximum mean power spectral density —

(aa)no greater than -70.0 dBm/MHz; or

(bb)no greater than -50.0 dBm/MHz provided that a listen before talk mechanism described in EN 302 435-1 is used to mitigate interference to other users of the electromagnetic spectrum;

(ii)have a maximum peak power no greater than -30.0 dBm or the equivalent transmission level; and

(iii)have a total radiated power spectral density of -75.0 dBm/MHz;

(h)in the frequency band 3.4 GHz to 4.8 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -50.0 dBm/MHz;

(ii)a maximum peak power no greater than -10.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density of -55.0 dBm/MHz;

(i)in the frequency band 4.8 GHz to 5.0 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -55.0 dBm/MHz;

(ii)a maximum peak power no greater than -15.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density below -65.0 dBm/MHz;

(j)in the frequency band 5.0 GHz to 8.5 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -50.0 dBm/MHz;

(ii)a maximum peak power no greater than -10.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density of -55.0 dBm/MHz; and

(k)in the frequency bands above 8.5 GHz when measured in any direction have—

(i)a maximum mean power spectral density no greater than -85.0 dBm/MHz;

(ii)a maximum peak power no greater than -45.0 dBm or the equivalent transmission level; and

(iii)a total radiated power spectral density of -90.0 dBm/MHz.
