Ofcom says its four-year process to release digital TV and wireless microphone frequencies for 4G mobile broadband will be completed this week, five months earlier than originally planned.

Wireless microphones, which are often used at conferences and for theatre productions, have now been moved to different frequencies. In addition, TV transmitters and receivers across the UK have been retuned. The final TV retune will be completed on Wednesday in northern Scotland.

EE (Everything Everywhere Ltd) has released its second-quarter and half-year results for 2013.

Service revenue during Q2 2013 fell by 4.4% year-on-year, although the company points out that the figure would have remained stable without roaming and mobile termination rate cuts. Turnover for the quarter was down 2.3% year-on-year.

We start this week's podcast by talking about an Android security risk - before moving on to new 4G services from EE, a drop in Nook tablet prices and a couple of quarterly results that disappointed the stock market.

In addition we discuss insurance complaints, Bluetooth Smart technology, a new multi-million investment in Shazam and some research about the future of apps.

The UK is beginning its week with news of a long-awaited sporting victory for Andy Murray. The telecoms world had its own much-anticipated good news last week, when European roaming rates fell again. And regardless of Neelie Kroes’ plans to abolish roaming rates completely, there’ll definitely be another roaming cut in 2014.

EE has switched on its double-speed 4G service in 12 cities across the UK, increasing its current average mobile data speeds to 24-30Mbps.

The higher speeds will initially be available at no extra cost to existing 4GEE customers as part of a promotional offer.
