That is why we are proposing to design the auction in a way that not only encourages investment, but also promotes competition and delivers wide coverage of services."
The four national carriers – O2, Vodafone, Three and Everything Everywhere – will be entitled to bid for spectrum, and there will be a maximum and minimum to the amount of spectrum that can be bid for.

The auction will begin in early 2012. Parts of Germany and the US are already using 4G networks.
