TalkTalk Group, which started life as part of Carphone Warehouse before demerging in 2010, has bought the Tesco broadband and fixed-line voice base from Tesco plc.

This gives it around 75,000 broadband customers and around 20,000 voice customers, which will be transferred to the TalkTalk network.

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.

We have a varied collection of mobile industry news stories in this week's podcast, including new rules affecting airline passengers with smartphones.

We also talk about BlackBerry giving up its European research centre, Vodafone installing fibre-optic broadband, Samsung's profits, spending on mobile advertising, M2M adoption and WiFi on trains.

Vodafone Ireland has signed a joint venture agreement with Irish energy company ESB to provide fibre optic broadband from 2015. It’s a €450 million project that’ll offer speeds of between 200Mbps and 1000 Mbps.

ESB began looking for a ‘fibre-to-the-building’ network partner in September 2012, eventually choosing Vodafone after a competitive tender process.

It's hardly worth mentioning the new iPad, is it?  Not because I'm unimpressed – although I'd describe it as more of an upgrade than a brand-new product – but because everyone else has been talking about it so much. And we'll be doing some more talking in Wednesday's podcast, so let’s move on...

"Harder, better, faster, stronger". Okay, so it's a lyric from Daft Punk (or Kanye West, if you prefer) but it might as well be the vague design brief for second-generation tablets.

A new study finds that an hour-long cell phone call causes a spike in biochemical activity in the user's brain. The researchers can't say whether that's a good thing or a bad thing, but the finding has renewed the debate over cell phone safety and raised calls for more health studies.

When I arrived at Mobile World Congress earlier this month, I said I wanted to see a bit of everything. Ground-breaking devices, advanced technology, network innovation... and some original applications as well. What I didn't realise was that I could find all of those in one place, on the SK Telecom stand.

For many people, the week after Mobile World Congress has a flat, post-Christmas, post-holiday feeling.

But not here at The Fonecast. We’ve produced two extra podcasts this week – themed around mobile audio and mobile usability – and there are more interviews from MWC lined up for next week.

Iain Graham, James Rosewell and Mark Bridge return to review their mobile industry predictions from last year. Which mergers, partnerships and developments did they forecast correctly... and which didn’t work out as planned?

Later in the programme, the team anticipates some of the topics that will be hitting the headlines during 2016.

Mark Bridge learns about the mobile technology trends at Mobile World Congress 2015 by chatting to James Rosewell of 51Degrees, Dr Kevin Curran from the IEEE and Chris Millington of Doro.

They talk about wearable devices, wireless charging, mobile operating systems and much more... including some of their favourite products from the exhibition.

We're taking a look back at the biggest mobile industry news stories from February 2015, including allegations that the UK's security service tried to breach SIM card security by hacking into one of the world's biggest SIM producers.

We also talk about the planned BT and EE merger, the creation of two new UK virtual networks, some acquisitions in the mobile payment arena and a new Ubuntu smartphone.

In today's programme Mark Bridge talks to Chris Millington, who's Managing Director for Doro UK and Ireland.

They discuss the state of mobile retailing in the UK, the future of wearable devices and - as you might expect - smartphones for seniors.

We're back with a month of mobile industry news, including takeover talks and takeover rumours. O2 and Three are said to be discussing a merger... but is there any truth in the suggestions that BlackBerry could be up for grabs?

We also discuss Apple's record-breaking quarterly figures, the highlights of CES and the launch of Microsoft Windows 10, as well as saying farewell to the current version of Google Glass.
