Mr Copper Foundation

From TARDIS Index File, the free Doctor Who reference.

The Mr Copper Foundation was a foundation that invented the Subwave network. Harriet Jones uses this technology to communicate with Martha Jones, Torchwood and Sarah Jane Smith. (DW: The Stolen Earth)

Judging by the name, Bayldon Copper may have founded the organisation and made the technology himself, as when the Doctor last saw him on Christmas 2007, he had a fortune of one million English pounds.
