a question about 802.11b
 

Greetings and sorry for my lack of knowledge on the subject.
does anyone know of a website for some circuity information for the 802....
I am not interested in stealing ideas I just would like to know how the got
onto 2.4 ghz.

Larry,

I would suggest that it is MUCH more practical and economical to buy
802.11b or 802.11b/g equipment ...

The 802.11 standards are HUGE and VERY complicated ... an any
practical implementation requires custom ASICs ... not a home-brew
project in any sense.

(I work for one of the world leaders in 802.11 ICs and modules, but
I am telling you straight, not trying to simply sell another NIC card ...)

p.s. If you'd like to browse the standards, they should be available
for free as .pdf downloads at http://standards.ieee.org/getieee802/

Actually my curiosity is not that I want to build one but more that I would
like to know how they got the signal onto 2.4 ghz. I am more interested in
the rf transmitter and receiver portions than in what they are using it for.

Most, if not all, modern chipsets that for 802.11b use direct conversion
to I and Q channels ... the major signal procesing is done at baseband.

For simpler, more general RF/IF needs, you might check out, for example,
the websites of
RF Microdevices http://www.rfmd.com
and
Maxim http://www.maxim-ic.com/
