This website provides the results from a survey, sponsored by the International Chamber of Commerce, which reports on the growth of wireless usage in the greater London area and compares networks built by "freenetwork" groups to those built by commercial providers. The results show that London has more than 5,000 wireless networks that are being used in offices, government buildings, prisons, police stations and government offices. The data is displayed clearly with impressive maps and detailed documentation. The reference list offers numerous links for more information about wireless networks.
