Samsung Electronics says it’s made a breakthrough with plans for a successor to 4G.

It’s developed the world’s first adaptive array transceiver technology that uses millimetre-wave Ka bands for mobile communications. This offers new opportunities for what could become fifth-generation (5G) mobile devices.

Vodafone is launching a new Carrier Services business, combining the carrier businesses of its operating companies with those from Cable & Wireless Worldwide.

This means it already has over a thousand communications service provider customers and partners worldwide.

Nokia has had a busy few days. First came the Asha 501, a ‘smartphone lite’ that introduced developers to a new version of the company’s Asha platform. This was followed by the Lumia 928, which is a Windows Phone 8 handset exclusive to Verizon Wireless in the USA. It’s quite like the Nokia 920, so we’re not missing out too much.

A new survey from the USA has published some of the reasons why consumers are giving up on mobile shopping transactions.

The 2013 Mobile Consumer Insights study, which was conducted on behalf of payment technology company Jumio, found that 68% of smartphone and tablet owners had attempted to make a purchase on their device. However, 66% of these people had failed to complete a mobile-based transaction.

The UK government says the roll-out of ‘smart meters’ for gas and electricity supplies will now begin in autumn 2015, according to the Department of Energy & Climate Change. This work had previously been expected to start from next summer.

The completion date for all UK homes and businesses to have smart meters has also been moved.
