History

Crown Castle UK was formed from the domestic transmitter network of the BBC, which was privatised in 1997.

It was a subsidiary of Crown Castle, but since 31 August 2004 it was owned by National Grid plc. On 11 October 2005 the company was renamed National Grid Wireless.

On 3 April, 2007 National Grid Wireless was acquired by Arqiva for £2.5 billion [cite web|url=http://www.arqiva.com/press-office/press-releases/press-releases-2007/arqiva-and-national-grid-wireless-combine-to-create-unified-uk-c|title=Arqiva and National Grid Wireless to create unfied UK communications infrastructure - Arqiva.com|accessdate=2007-04-04] .

National Grid Wireless led a consortium bidding for the second UK national DAB multiplex licence, but was unsuccessful. The licence was awarded instead to 4 Digital Group in July 2007.
