Shock - WiFi Actually Generating Revenue Streams

I recently had the “pleasure” of visiting Milton Keynes; the railway station was packed with what were surely tourists – some mistake here? Admittedly, all looking in a hurry to get back to London… does “Stratford-Upon-Avon” translate aurally as “Milton Keynes” in some languages?

Anyway, point being MKC has gone into the world of WiFi as a service, a revenue generating service no less, guaranteed fixed costs, open API to build apps on and instant revenue stream options. And it works great; I went there and downloaded the app (left the T-shirt in the tourist information office though). Suffice to say, this is a long way from WiFi c. 2003, so check out the full study to get a new angle on how wireless technology now makes money, rather than just eating it: 
WiFi that a) works over a large area and b) generates dosh… Was I dreaming perchance?
