Ofcom says the UK has now switched from analogue to digital terrestrial television, such as the Freeview and Top Up TV services.

It means the former analogue TV spectrum is free to be used for 4G mobile data services. This so-called ‘Digital Dividend’ is due to be auctioned in a few months’ time.

This week we're talking about the UK's first 4G mobile phone tariffs, Ofcom's consultation about contract pricing and O2's response to its recent network outage.

We're also looking at quarterly results from Google and Nokia, Apple's iPad design, Microsoft's tablet pricing and texting cows.

Ofcom has announced plans for a consultation on how to protect consumers from price rises that happen within fixed-term contracts for landline, broadband and mobile phone services.

Current rules insist that communications providers give their customers at least one month’s notice of any significantly detrimental change to their contractual terms.

The UK’s ‘big four’ mobile phone operators - EE, Telefónica O2, Three and Vodafone - have formed a jointly-controlled company called Digital Mobile Spectrum.

It’ll help any households experiencing TV signal interference when 4G mobile services are introduced on the 800MHz frequency band.

Ofcom has announced that fixed-line and mobile network providers in the UK must offer a new ‘next generation’ text relay service to all customers who require it within the next 18 months.

The current text relay service service, which is available to people with hearing and speech impairments, involves an assistant who converts speech to text and vice versa for two people having a conversation. However, it can be slow and offers little opportunity for a genuine ‘real time’ conversation.
