Tesco mobile arm 'under threat'

Supermarket giant Tesco’s mobile phone arm could be put out of business under network shake-up plans from UK telecoms regulator Ofcom, it was reported today.

Ofcom wants to make some of the 900MHz radio spectrum, currently used by Vodafone and O2 for second-generation calls and text services, available for other operators. Parts of the spectrum could be put up for auction in 2009.
