British mobile crowd-sourcing firm OpenSignal has just raised $4 million (around £2.4 million) in a funding round led by Qualcomm, with O’Reilly AlphaTech Ventures and Passion Capital also participating.

OpenSignal offers consumers an app that shares real-world mobile phone coverage information, enabling users to see what levels of service other people have experienced.

Even at Mobile World Congress, the relevance of the mobile network operator can sometimes be forgotten. So for a different perspective on this year's event, we spoke to Samuel Johnston from British mobile crowd-sourcing firm OpenSignal.

Samuel discussed the announcements from MWC14 and OpenSignal's latest report into 4G LTE coverage around the world, as well as giving us an exclusive insight into OpenSignal's next research subject.

A new report about the state of 4G LTE coverage around the world has been published by UK-based business OpenSignal, which creates crowd-sourced mobile network coverage maps from its Android and iOS apps.

The report looks at two key concerns: download speeds and the proportion of time spent in an area covered by an LTE service.

Yesterday afternoon at Mobile World Congress in Barcelona, crowdsourced coverage map provider OpenSignal was named the UK’s most innovative mobile company.

Five finalists took place in a final pitch and judging session as part of the Smart UK Project.

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.

In the past five years, what started as an advertising message - “there’s an app for that” - has become a challenge to developers. It’s become part of 21st century culture. And it’s become an totem for journalists to pin their most outrageous app-based stories to.

Roadroid doesn’t need the attention-grabbing headlines.

What would you say to a tiny little device that enabled you to recharge your smartphone almost anywhere, whenever you wanted?

This is pretty much what a US-based company called Nomad is promising. In fact, they sent me two of their latest products to try.

Apple kicked off its 2014 Worldwide Developers Conference (WWDC) last week with an announcement about the forthcoming iOS 8 operating system for iPhone, iPad and iPod touch. There was some catching up, some innovation and a couple of new services designed to work with home automation and health/fitness devices. What’s Tim Cook’s plan? We’ll have to wait and see.

Bitcoin, as Wikipedia tells me, is a peer-to-peer payment system introduced as open-source software in 2009. It’s a ‘virtual currency’ that can be used for transferring money and for buying products or services, although only if your chosen retailer accepts Bitcoin.

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.
