A new study by the Economist Intelligence Unit (sponsored by InnoPath) has found that only a minority of telecoms executives believe growth in revenue from mobile data services will make up for a decline in voice revenue over the next five years. Almost 200 senior execs in the mobile telecommunications industry were interviewed but only 44% thought data growth would compensate for the voice decline.

New research from Convergys Corporation says 61% of UK consumers would spend more with their chosen mobile network if they were able to choose options that fitted their needs. Consumers are willing to include payment for broadband, TV and even game consoles with their mobile service – but only if the deal is flexible enough to suit the customer.

Currently 49% of consumers said they don't receive any promotions or 'bundle' offers from their providers, although 72% said they'd like to.

As usual, you can listen to the podcast on the main page of our website.

Iain, James and Mark take their regular look at the latest mobile industry headlines. This week there's talk about Symbian, a possible delay to the Orange/T-Mobile merger, mobile phone components that rely on quantum physics... and plenty more.

I.T. and networking company Cisco has predicted that annual mobile data traffic worldwide will reach 3.6 exabytes (3.6 billion gigabytes) per month by 2014. That's a 39-fold increase from last year, which represents a compound annual growth rate of 108%.

Cisco says this increase is being driven by the popularity of mobile-ready devices and by mobile video consumption. Mobile video is expected to represent two-thirds of all mobile data traffic by 2014, increasing 66-fold from 2009.
