we've had it here, in London for 18 months. The Borough of Islington in North London launched a free access wireless network in June of 2005.
The 'Technology Mile' as it was dubbed runs from The Angel to Highbury Corner, providing one mile of unbroken free wireless broadband access to residents, businesses and anyone who happens to be passing. It works extremely well, and in phase two of the project the council plans to give free computers to shops,cafes, and restaurants, so customers can access the internet.
The Norfolk network is certainly the largest free WiFi facility in the UK in terms of the area covered, but there will be others. The Norwich project has a two-year lifespan, and at the end of that period - in 2008 results will be eva,luated to determine whether or not it should continue. Projects like this have to be funded with public money, and local authorities are quite rightly concerned to make sure that there's a benefit to the commnity as a whole, rather than to a tiny sector of it, before committing to spend the considerable sums of money involved in setting up the necessary hardware.
