Patents were a very popular topic of conversation last week. Google sold its Motorola Mobility smartphone business to Lenovo but hung on to most of the patents. Does this mean the patents were the most valuable part of the business? Well, when you look at the difference between the original purchase price and the sale price, it seems a reasonable conclusion.

UK communication regulator Ofcom has announced that all the UK’s major mobile phone networks are now covering 90% of UK homes with 3G service.

All were required to cover 90% of the UK population with 3G service by 30th June 2013. However, calculations published by Ofcom in November showed that Vodafone had only reached 88.66% coverage.

After initially suffering from slow pick up by consumers, 4G has begun to accelerate, and is now well on the way to the forecasted one billion subscribers by 2017. In fact EE, owner of T-Mobile and Orange, recently announced the addition of 493,000 new 4G customers to its existing base of 1.2 million.

A new report has highlighted the issue of poor mobile phone coverage in rural Sussex villages. BBC Sussex invited me onto their ‘Sussex Breakfast’ radio show to explain what could be done - and, as usual, I made enough notes for a lecture rather than a three-minute interview.

Here’s what I would have liked to have said if I’d been given a disproportionate amount of time to talk.

Ofcom’s proposal to increase annual licence fees for the 900MHz and 1800MHz spectrum bands in the UK could adversely affect investment in the UK’s 4G services, according to the GSMA.

A consultation into the proposed increases ended on 16th January, with an Ofcom decision expected in the next few weeks.
