Term
802.11
Definition
LANs transmitting at 1Mbps or 2Mbps
2.4GHz frequency
Data encoding:
(FHSS)frequency-hopping spread spectrum
(DSSS) direct-sequence spread spectrum
Term
802.11a
Definition
LAN bandwidth of up to 54Mbps
5GHz frequency

Data encoding:
(OFDM) orthogonal frequency division multiplexing
Term
802.11b
Definition
Bandwidths of up to 11Mbps
Fallback rates of 5.5,2, and 1Mbps
2.4GHz frequency
Data encoding:
(DSSS) direct-sequence spread spectrum
Term
802.11g
Definition
Bandwidths of up to 54Mbps
2.4GHz frequency
(While able to obtain faster speeds, it also suffers from the same interference problems n herent with 802.11b- having to share the spectrum with other devices using that frequency
Term
802.11n
Definition
Bandwidths of up to 300Mpbs
5GHz frequency (its also compatible with 2.4 GHz)
advantage: higher speed and a frequency that does not have as much inteference
