National Grid Wireless

National Grid Wireless (formerly Crown Castle UK) is a company which provides telecommunications infrastructure and broadcast transmission facilities in the UK. Its main customers are broadcasters and mobile phone network operators, and its main asset is a network of over 1,000 radio and television transmission sites. It is owned by the Australian investment house Macquarie Bank [cite web|url=,,2049277,00.html?gusrc=rss&feed=4|title=Macquarie buys digital bidder|accessdate=2007-04-04] , which also owns former competing broadcast company, Arqiva.


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=|title=Arqiva and National Grid Wireless to create unfied UK communications infrastructure -|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. [cite web|url=|title=Channel 4 wins radio multiplex bid -|accessdate=2008-01-08]
