Can 802.11 Become A Viable Last-Mile Alternative?
NikiScevak writes "As telco's around the world move from government hands to private investors the incentive for them to create compeition at the wholesale DSL level drops dramatically. The CSIRO in Australia are investigating the use of Wireless LAN technology 802.11b as a means through which to provide alternative broadband access, achieving range of up to 7km with standard components."
Radio waves and light are the same thing. They should work exactly the same.
802.11 is about as secure as your wired LAN or any other unencrypted traffic flying out of your computer. Security is an end-to-end argument and it does not behoove the protocol to make any security guarantees (neither ethernet nor 802.11 do this).
I've had enough about people saying how insecure 802.11 is just because someone can sniff your packets. Its the same for any shared medium (think ethernet or the internet backbone). So if you are paranoid about your security, encrypt all the traffic that is flying across the wire.
