Wireless Mesh Network Trial in the UK
Huw writes "With cable only in selected areas and ADSL only available within three miles of selected telephone exchanges, residents of the South Wales valleys are pretty much stuck with dial up connections to access the internet. BT may have the answer with a wireless solution according to this article from the BBC. Quite how wireless networking will cope with a hilly area like this remains to be seen, but hopefully we'll soon see broadband available for anyone who wants it." The company home page has some more information about their system.
A packet sniffer will pick up a packet whether you pull it out of the aether over a wireless link, or by connecting to an insecure switch downstream. What the signal is carried on does not matter. If it routes on the internet it, by definition, can be sniffed, dissected, and disseminated.
Weather may be their problem, a profound misunderstanding of technology is yours. At least the weather will clear up on its own.
