In this week's podcast we're talking about the potential purchase of the O2 UK mobile network by BT.

We also discuss new tablets from Nokia and Jolla, the end of a patent battle, mobile payments via instant messaging, app development for the Apple Watch and plans to make even more spectrum available for mobile broadband in the UK .

UK communications regulator Ofcom has confirmed its plans to make more radio spectrum available for mobile broadband services.

Following a recent consultation it now aims to release part of the 700MHz frequency band to mobile network operators.

Ofcom’s board has chosen Steve Unger as its interim Chief Executive from the end of this year.

He’ll be in the role until the UK communications regulator makes a permanent appointment in the New Year.

Time for another podcast presented by Iain Graham, James Rosewell and Mark Bridge. They begin this week's programme by talking about the latest enterprise-friendly developments from BlackBerry.

Next comes a new survey from Ofcom about the UK's 4G data speeds, followed by news about TalkTalk's MVNO deal with Telefonica, the growth of WiFi in the home and a report from AVG about social media sapping smartphone performance.

Ofcom has published its first research into the consumer experience of UK mobile broadband services since the 4G auction last year. The regulator’s own engineers conducted around 210,000 tests of 3G and 4G services on smartphones in Birmingham, Edinburgh, Glasgow, London and Manchester between March and June 2014.

Download speed, upload speed, web page loading times and latency were all measured.
