A horse box and eight SIM cards. That’s the basic technology keeping the BBC’s Olympic Torch Relay broadcasts on the air and on the road.

The converted DAF horse box is being driven in front of the runners as they carry an Olympic torch along the relay route. It’s equipped with four cameras and a mixing desk, enabling a choice of views to be recorded and broadcast for 12 hours per day throughout the 70-day relay.

A BBC survey into 3G coverage across the UK has shown that people who were able to receive a data connection only managed to use a 3G signal for 75% of the time.

For almost a quarter of the time they were connecting to 2G GPRS technology.

The BBC is conducting a month-long survey that's designed to measure the availability of 2G and 3G mobile phone services in the UK. It's using an Android application that'll collect information and will anonymise it.

The UK 3G Survey app has been developed for the BBC by Epitiro.

Some of the UK's largest technology and media companies are working together to see if unused TV spectrum could be used as an alternative to WiFi and mobile data.

The BBC, BSkyB, BT, Microsoft, Nokia and Samsung are among the companies that have formed the Cambridge TV White Spaces Consortium.

For those that don't regularly watch the BBC News Channel at 5pm here's a rather hasty recording of an interview with our very own Mark Bridge concerning "Quick Tap"; a rather underwhelming new mobile payment product from Orange and Barclaycard.

I noticed a new phenomenon at Mobile World Congress this year: Beer O’Clock. Come 5pm Monday through Wednesday, companies with larger booths would break out the Cerveza, Vino, Cava and a small number of Orange juices. All very sociable and fun… until the music started.

So, that’s another Mobile World Congress in the bag. Yes, it was bigger than ever. Just like last year. Just like the year before, too.

I was ready to poke fun at IBM for its sponsored graffiti wall at Mobile World Congress this year. Graffiti and IBM don't have a comfortable history, as anyone who remembers the Linux campaign from 2001 will tell you.

Some companies have saved their big announcements for the week of Mobile World Congress. Samsung and Nokia, for example. Others have issued a press release in advance.

Iain Graham writes:

Vodafone’s admission last week that ‘some customers’ may have been experiencing issues with mobile services came three weeks late for me. I’ve been having my own ongoing battle with the network since the beginning of the month.

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.
