There’ll be 676 million 4G LTE handsets shipped worldwide in 2015, according to new figures from ABI Research.

That’s an increase of 204 million units from this year.

Vodafone has started rolling out Carrier Aggregation technology in the UK, which offers 4G users the ability to enjoy data speeds that are up to three times faster than conventional 4G connections.

Carrier Aggregation, also known as LTE Advanced (LTE-A) or 4.5G, allows network operators to combine parts of their radio spectrum for faster connections.

A new research report from Berg Insight says the market for mobile machine-to-machine (M2M) communications has begun to move from the 2G to 3G and 4G technologies.

Although cellular M2M devices on HSPA and LTE networks are expected to account for under 20% of the global market by the end of 2014, they’re forecast to dominate with more than 50% by 2018. Meanwhile, shipments of 3G/4G M2M devices are expected to overtake 2G M2M in 2017.

EE says it’s planning to allow UK customers to make voice calls over WiFi connections “with a higher quality and greater degree of reliability than unmanaged VoIP services”.

Calls will be available via the standard dialler on the customer’s smartphone, with SMS messaging also available.

Huawei says it’s successfully run the world’s first GSM-LTE Dynamic Spectrum Sharing trial with Vodafone Spain.

It’s a technology that allows real-time changes to be made to the allocation of frequencies for 3G GSM and 4G LTE traffic.

As any Star Trek fan knows, Apple didn't invent the tablet computer. The crew of the Enterprise regularly used handheld devices that looked remarkably like an electronic clipboard... or an iPad. In fact, engineers in the 1960s were working on tablet devices as the original Star Trek series first aired.

Then there were the Microsoft Tablet PCs from around ten years ago. I bought one - an Acer TravelMate - as my main computer and loved it. I even loved the special pen that was needed to write on the screen.

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.

Dr 'Bones' McCoy moves an electronic device over a patient’s leg encased in a plaster case. The device immediately identifies swelling within the cast, alerting the doctor to take action.

But this isn't a medical tricorder being used by the doctor. It's a Google Nexus S mobile phone. And the situation isn't set in the 23rd century. It's now.

Europe's leaders want mobile phones and WiFi networks banned in schools. Well, that's what the headlines appear to say.

Except - as often seems to be the case with most mobile phone health warnings - things aren't that simple. So let's start at the beginning.

Almost everyone in the mobile telecoms industry seems to be looking for a perfect payment system that'll transform their mobile phone into some kind of electronic wallet. Yet despite many trial schemes – and a few commercial launches – cards and cash are still favoured by consumers and retailers in much of the world.

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.
