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 guardian of the UK's electromagnetic spectrum is the communications regulator, Ofcom.

“Every judgement of conscience, be it right or wrong, be it about things evil in themselves or morally indifferent, is obligatory, in such wise that he who acts against his conscience always sins.”
