Wireless Telegraphy Act is (with its variations) a stock short title used for legislation in the Republic of Ireland, South Africa and the United Kingdom relating to wireless telegraphy. The Wireless Telegraphy Acts are laws regulating radio communications in the United Kingdom. Wireless telegraphy as a concept is defined in British law as "the sending of electro-magnetic energy over paths not provided by a material substance." The term telegraphy, although best known in relation to the electric telegraph, relates to the sending of messages over long-distances. Wireless telegraphy is differentiated from electrical telegraphy in that the messages are transmitted via electromagnetic means (light or radio) rather than via a physical electrical cable connection. The current (2018) supervisor of the UK's electromagnetic spectrum is the communications regulator, Ofcom.
