The new Apple iPad tablets, Google's latest Nexus devices, Android Lollipop, wearable tech from will.i.am and the world's slimmest smartphone all feature in this week's podcast.

We're also talking about free mobile data for Christmas, 4.5G technology being rolled out in the UK, 5G technology being tested in South Korea, the end of an era for webOS and video messages that self-destruct.

Samsung Electronics has announced two milestones in the development of 5G mobile technology.

It’s achieved 7.5Gbps (940MB per second) in a stationary environment and 1.2Gbps (150MB/second) from a vehicle travelling at over 60mph. Both are thought to be industry firsts.

We open this week's podcast with news about the European Commission and South Korea working together on 5G mobile technology.

There's a quick look at Samsung's new tablet, some acquisition deals to talk about, a tax investigation, research into wearable devices and plenty of other mobile industry news as well.

The European Commission and the South Korean government have signed an agreement that’ll see them working together to create a global definition of exactly what 5G mobile technology is, what it’ll do and when it’ll be available.

Neelie Kroes, Vice-President of the European Commission for the Digital Agenda, and Mun-Kee Choi, who’s the Minister of Science, ICT and Future Planning (MSIP) for South Korea, also agreed to co-operate on 5G research.

As one show closes, so another show opens.

It’s now more than a week since we bid a sad farewell to Mobile World Congress 2014 – I imagine hotel rooms for 2nd to 5th March 2015 are already being booked – but there’s now CeBIT in Germany to look forward to. Prime Minister David Cameron kicked things off last night with a speech that talked about UK-German partnerships, more funding for research around the ‘Internet of Things’ and the development of 5G technology.
