PART 4USE OF ULTRA-WIDEBAND EQUIPMENT IN AUTOMOTIVE VEHICLES AND RAILWAY VEHICLES

Exemption

12.  The establishment, installation or use of ultra-wideband equipment complying with the terms, provisions and limitations in regulation 13 is hereby exempt from the provisions of section 8(1) of the Act.

Terms, provisions and limitations

13.—(1) The exemption provided for in regulation 12 shall apply to ultra-wideband equipment which complies with the requirements of paragraphs (2) to (4) of this regulation.

(2) The ultra-wideband equipment must be used in an automotive vehicle or in a railway vehicle.

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