Though rural dwellers are often broadband-poor, there seems to be plenty of companies lining up to serve them in the UK. Regulator Ofcom just announced participants for its "white space" or unused spectrum trials, including Microsoft, Google, Click4Internet and British Telecom. Redmond's going to test WiFi-like services to underserved Glasgow, while Click4internet will assess rural broadband in remote or tricky locations. Google has signed on as a potential database provider, and other use cases like traffic management will be tested by BT and others. Ofcom wants to launch such services by next year and released a blueprint detailing how existing mobile and digital terrestrial TV spectrums could be divvied up.
