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.

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.

This week's podcast begins with Ofcom's plans to cut the wholesale cost of inter-network mobile phone calls. But what benefit will consumers see?

Iain, James and Mark then move on to discuss luxury smartphones, a new handset on the high street, mobile broadband for aircraft passengers, government monitoring, the growth of smartphones - and 4G-equipped donkeys.

In today's programme we're talking to James Atkins, co-founder and Chief Marketing Officer of smartphone manufacturer Kazam.

The company launched earlier this year and has just announced its first seven Android-based handsets. James explains the story behind Kazam's creation, the company ethos, its product range and its plans for the future.

The past few days have been a good time for launches. Twitter has floated on the stock exchange, Kazam has revealed its smartphone range and EE has created a tariff with a million gigabytes of mobile data.

On the other side of the coin, Acer's CEO is quitting, Vodafone UK has missed its 3G coverage target and hackers can take control of your handset's camera to ascertain PIN codes.
