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.

Mark Windle, head of marketing at OpenCloud, predicts that this year’s reduction in the number of traditional telecoms operators in some countries will provide an opportunity for other operators to innovate and capture market share in 2016.

He says next year will be a year of rapid change for telecoms… whether it’s MVNO disruption, competitive tariff pricing or simply defence from the ‘dark art’ of hacking.

The most memorable moments in life often go unrecorded. You don't have your camera in your hands. Your finger is still hovering over the 'pause' button on your audio recorder. Or you were simply too busy experiencing whatever was happening. It's all about the one that got away.

That's where Kapture can help.

James Rosewell shows me a colourful roll of paper that's the width of an iPhone but well over three metres long. When I look closer, I can see it's a printed copy of the Wall Street Journal's mobile website. That's a lot of scrolling to do... and a pretty unfriendly user experience for anyone reading the news online. Why does it work so badly?

We start this week's podcast with Tesco's plans for a Hudl-branded smartphone. Next comes some potentially good news about the 'patent wars' affecting the mobile industry - although there's certainly no sign of a ceasefire.

Later we discuss an announcement from Facebook about its mobile advertising scheme, an unfortunate mistake for O2's Travel service, a new 20 megapixel camera-phone and an automotive investment by Nokia.

In this interview Mark Bridge talks to Jijesh Devan of QuickPlay Media about the opportunities and challenges of bringing video services to smartphones and other internet-connected devices.

Their conversation took place on the QuickPlay stand inside the App Planet area of Mobile World Congress in February.

We have something for everyone in this week's podcast. There's bad news as Samba Mobile closes, bad news as Apple and Samsung suffer product faults... and bad news as wearable devices are criticised for the poor user experience they offer.

Yet there's plenty of good news as well, including the launch of a new UK mobile payment service.

Telefonica sets up its own mobile advertising business, Mozilla puts an interim CEO in place and Nokia suspends sales of its flagship Windows 8.1 RT tablet: all topics for discussion in this week's podcast.

We're also talking about the future growth of Orange Money, EE's online activity, mobile broadband growth and the Loch Ness monster being spotted on Apple iPhones.

When the topics of mobile technology and security are discussed, the conversation can end up focussing on third-party software solutions.

Inside Secure has a different perspective. It's a specialist in embedded security; building protection in from the start. To learn more, Mark Bridge caught up with Loic Hamon, Vice President of Corporate Development at Inside Secure, at the company's hospitality suite during Mobile World Congress.
