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.

I recently had to, as a last resort, call the customer service department of a large communications company about a problem I currently have with a piece of equipment. I know I could have looked in the 150-page accompanying instruction manual but I haven't got half my life to spare! (as I mentioned in my previous blog piece on handsets!)

Businesses these days are telling us "Customer service has been outsourced to the Indian subcontinent and technologically streamlined in order to offer our customers a better, more efficient service"!

So – you’re thinking about buying a new mobile phone. A smartphone. And yes, I mean a real smartphone, not just something with a touchscreen that looks nice.

I know, I know. You’re tempted by the iPhone. It’s all those apps, isn’t it?  100,000 and counting.

Yet Android is catching up. Admittedly it’s still got a long way to go to match that six-figure total… but the signs are certainly there.

I really don’t want to make a habit of pointing at surveys and laughing – or even scratching my head in the kind of theatrical gesture used by Stan Laurel – but I should imagine there was some wry amusement at Strategy Analytics this week.

They’d been talking to car owners in Europe and the USA about their preferred brand for Bluetooth headsets and speakerphones. In the United States, 45% of respondents said Bose was their preferred brand. Excellent news for Bose. Excellent news for Bose stockists. Except...

I’m always on the lookout for technology that’ll make life easier. That’s one of the reasons the Movon MB80 caught my eye. It’s a Bluetooth handsfree unit that you wear on your wrist. The MB80 is designed for the times your phone’s not convenient and you don’t want to miss a call – but you also don’t want to wear a Bluetooth headset. Perhaps you’re playing sports or are out for an evening with friends. The Movon Bluetooth wristband rings or vibrates when someone calls – and then can be used as a handsfree loudspeaker.

"Mobile: new cancer alert" - The Daily Telegraph

The front page of Saturday's Telegraph led with the headline "Mobiles: new cancer alert" re-igniting fears about mobile phone usage. The centrepiece of the article is "a £20 million, decade long investigation, overseen by the World Health Organization (WHO) will publish evidence that heavy [mobile phone] users face a higher risk of developing brain tumors later in life". How should this topic be reported and what will it mean for our industry?

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.
