[olug] Wireless LAN

[Eric Penne]

802.16 is meant as a broadband connection like DSL or cable modems. The
standard won't be finished until January 2002 at the earliest.  They
have almost finished the MAC layer.  There are proprietary technologies
that can do this type of thing but hte cost is very prohibitive. 
802.16 is looking at 2 ranges of frequencies 2-11 GHz and 10-66 GHz. 
Why they overlap is beyond me right now.  802.11b is 11 Mbps at 2.4 GHz
and 802.11a is 52 Mbps at 5 GHz.  I don't know what the proposed speeds
are for 802.16.  They are trying to use the good parts of 802.11 in
this standard though so the hardware can be quickly implemented and get
to market.  I don't expect this to take off for another 3 years though
since 802.11a is coming, unless security of the wireless infrastructure
takes precendence or companies can start making a profit from
broadband.
