| 17 March 2021 Hot on the heels of announcing their plans to extend and improve basic 4G connectivity around the country, the UK’s mobile operators are celebrating their principal gains in the 5G arena with low-band and mid-band spectrum. Four companies – EE , Hutchison 3G UK (owner of the Three UK network), O2 parent Telefónica UK and Vodafone Limited – took part in the principal stage of the auction, which involved them bidding for airwaves in 34 ‘lots’ to determine how much of the available spectrum they each secured. Principal stage bidding has now ended and UK comms regulator Ofcom has revealed that the total revenue raised is £1.356 billion.
