Not the catchiest headline you’ll ever read, but when the big mobile operators start to co-operate you know there’s something going on. It involves part of the 3G spectrum they already own, the Time Division Duplex (deep breath, stick with it). Why does it matter? Well, as the rise of smartphones gums up the pipework and with the Olympic Games in the offing, any extra capacity is valuable. It still doesn’t get round the wider issue of getting fully-fledged mobile broadcasting into the UK. That requires spectrum, masts and towers, so a lot of money and the buy-in of mobile operators to put receivers into handsets.
