David Cameron outlined his Spectrum Strategy for the UK's digital future, touching on 5G mobile broadband, better use of existing wireless frequencies and (as we keep hearing) the internet of things. In a speech at CeBIT 2014 in Hanover, he said: "This is a world on fast forward, a world of permeant technological revolution. Countries like the UK and Germany will only succeed if we have a relentless drive for new ideas and innovations." The government plans to stake £45 million (around $75 million) on research into that pesky internet of things, with the Prime Minister reckoning that improved spectrum use will lead to economic benefits of around £100 billion by 2025 -- and probably less spinning wheel of death.
