We’re back from Mobile World Congress – and what a show it was. Located at a new site that saw more visitors than ever before, the show had everything… except any particularly obvious theme from hardware manufacturers. Last year was the year of the quad-core smartphone, this year there was plenty of incremental innovation but nothing truly startling.

The final stage of Ofcom’s 4G UK mobile spectrum auction has been completed, with two network operators choosing to pay more for a specific part of their chosen spectrum band.

Ofcom announced the winners of the main 800MHz and 2.6GHz auction just over a week ago.

Telecoms regulator Ofcom has announced the winners of the UK’s 4G mobile spectrum auction, which has finally been completed after more than 50 rounds of bidding. It means that faster mobile broadband services will soon be offered to more people by more companies.

The UK’s major mobile networks - Everything Everywhere Ltd (EE), Hutchison 3G UK Ltd (Three UK), Telefónica UK Ltd (O2) and Vodafone Ltd - have all won radio spectrum.

We start this week's podcast with financial results from EE - along with new phones from LG and HTC.

There's also a merger between mobile browser companies, mobile security from Vodafone, free WiFi from Barclays bank, a preview of Ubuntu for smartphones... and much more.

Defence, aerospace and security company BAE Systems plc has formed a five-year partnership with Vodafone that’ll see them providing businesses with a range of communications security products and services.

In addition to this security partnership, BAE Systems is also moving its mobile services to Vodafone.
