Mobile operator
O2 UK (Telefonica) has warned that
Ofcom’s plan to auction off the 800MHz and 2.6GHz radio spectrum frequencies, which would be used by a new generation of
4G superfast Mobile Broadband services, could be put at “further risk of delay” after the regulator allowed T-Mobile and Orange UK (Everything Everywhere) to launch the country’s first 4G service over their existing 1800MHz (
3G) band.
