2Interpretation

In these Regulations –

  • “ERP” means effective radiated power, as defined in the Radio Regulations;

  • “EIRP” means equivalent isotropically radiated power, as defined in the Radio Regulations;

  • “field strength” means the magnitude of a component of specified polarisation of the electric or magnetic field, and a reference to the field strength of any signal means the field strength of that signal when measured at a distance of 10 metres;

  • “the Radio Regulations” means the 1982 edition of the Radio Regulations, as revised in 1985, 1986 and 1988, annexed to the International Telecommunication Convention 1982f1 pursuant to Articles 43 and 83 of that Convention; and

  • “relevant apparatus” means wireless telegraphy apparatus or apparatus designed or adapted for use in connection with wireless telegraphy apparatus.

3Exemption

Subject to regulation 4, and except as provided for in regulation 5, the establishment, installation and use of any station or apparatus for wireless telegraphy of a description set out in the Schedule hereto (hereinafter referred to as a “relevant low power device”) are hereby exempted from the provisions of section 1(1) of the 1949 Act.

4Terms, provisions and limitations

The exemption provided for in regulation 3 shall be subject to the terms, provisions and limitations that –

the relevant apparatus comprised in the relevant low power device shall be for the time being approved under section 84 of the 1984 Act; and

(b)

the relevant low power device shall not –

(i)

infringe any requirements for the time being applied to it by or under any enactment for the purpose of preventing it from causing interference with any wireless telegraphy; or

(ii)

cause undue interference with any wireless telegraphy.

5Exceptions

The exemption provided for in regulation 3 shall not extend to any station or apparatus for wireless telegraphy the establishment, installation or use of which is exempted from the provisions of section 1(1) of the 1949 Act by –

(a)

6Restrictions on use

Where the Secretary of State has reasonable cause to believe that a relevant low power device is causing undue interference with any wireless telegraphy, any person who is in possession or control of that device shall on the demand in that behalf of any person authorised for such purpose by the Secretary of State (“the authorised person”) forthwith cause the use of that device to –

(a)

cease; or

(b)

be restricted in the manner specified by the authorised person.

Explanatory note

(This note is not part of the Regulations)

These Regulations provide for the exemption from the provisions of section 1(1) of the Wireless Telegraphy Act 1949 of various low power devices. Accordingly it will not be necessary to hold a licence to install and use apparatus to which these Regulations apply. The descriptions of low power devices which are exempt are set out in the Schedule.

Regulation 4 provides that, for the exemption to apply, certain conditions must be complied with. The low power device must be for the time being approved under section 84 of the Telecommunications Act 1984. Devices exempted from licensing by these Regulations must not cause interference.

The Regulations do not apply to apparatus which is exempt from the licensing requirement under certain other instruments (regulation 5).

Regulation 6 requires that the use of the device must cease, or its operation must be restricted, on the demand of a person authorised in that behalf by the Secretary of State. Failure to comply with such a demand is an offence under section 3 of the Wireless Telegraphy Act.
