These days, a guy on a rooftop carrying an unwieldy metallic object probably isn’t interested in your chimney. More likely than not, he’s trying to connect to the nascent CZfree.net network, which aims to bring broadband to residential users.
An imperfectly-wired urban area like Prague seems like the perfect place for this kind of thing. For the same reason that mobile phones were poised to take off in a country with lousy telephone service, wireless internet service deserves to overtake wired internet service.
Two of the major changes I observed in Prague during my trip, compared to six years ago, were the sudden ubiquity of cell phones, and the proliferation of internet cafes. I don’t know if it’s because of all the tourists, or because in-home internet access is still not common. link via boing boing
