whats the difference, and what exactly is bluetooth, and how does it differ from 802.11b,g

and what is the specs of 802.11b, 802.11g, whats the difference in those two?

and whats the fastest wireless networking speed right now, isnt it like 108mbps???

thanks!!!
 
Bluetooth is frequency hopping, Personal Area Network (PAN) hardware. Short range. Printers, PDA's etc.. though I believe the newest version of bluetooth is using slightly more powerful radios, increasing the range. It is not however a substitute to WLAN gear. (.11b g and/or a. All use direct sequence spread spectrum)

The difference in .11b and .11g for the average user is available bandwidth. Speed. Specifically the native signalling rate. 11 Mbps for b and 54 Mbps for g.
Underneath they use different modulation types. CCK for 11 Mbps transmissions and OFDM (.11a also uses OFDM) for 54 Mbps.

108 Mbps is proprietary extensions using multiple frequency sets (channels), 2, and also compression. Broadcom is coming out with a 125 Mbps radio that only uses the one channel soon.
