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.

It’s the latest tech update that everyone is talking about; for good or for bad, iOS7 is here and it’s something that all mobile app developers need to take into consideration. So, how have these changes to Apple’s system had an impact on third party apps?

The dependency on mobile phones is at an all-time high. Used for everything from the weekly grocery shop to monitoring heart rate, it’s no underestimation to say that we would be lost without our mobile phones. So when it takes days for your phone to be repaired, it has a considerable impact on your normal daily life.

Ring-back tones offer consumers yet another way to customise their mobile phone service. Yet despite this – and the revenue opportunities they provide – many mobile network operators don’t offer them.

Recently I spoke to Florent Stroppa, General Manager Europe for value-added service specialist OnMobile, to find out why the UK doesn’t really seem to be bothered about ring-back tones… and whether the next-generation of ring-back services will change this.

Talk about a difference. In preliminary results last week, HTC announced its first-ever quarterly loss while Samsung revealed record quarterly profits.

Curiously, many of the week’s other news stories also had a companion headline to provide a contrast.

Things didn’t look so bad in the mobile industry last week. After the shock of BlackBerry’s job losses and restructuring, it seemed as though the saga could be reaching a conclusion. On Monday shareholder Fairfax Financial announced a bid to buy the company. BlackBerry’s board of directors has approved the terms of the agreement, although it’s still able to consider alternative proposals as well.

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.
