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.

UK mobile operator EE says it switched on its 4G service in the Channel Tunnel two months ago and has now provided 4G service to more than 25,000 EE customers.

Since September, 282GB of 4G data has been carried on EE’s network from the tunnel. Average download speeds are 13.5Mbps, with peak speeds of 57Mbps delivered.

A video advertisement from Telefonica-owned UK MVNO giffgaff was likely to cause serious or widespread offence, according to a ruling by the Advertising Standards Authority.

The video clip was promoted via giffgaff’s Twitter account, which was also available via an embedded feed on the giffgaff website. As well as showing a link to the video clip, the tweet said “The situations in our new videos are, well, awkward. #NSFW #alltheboss”.

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.
