Spelling: 802.11
802.11 [1] is the original IEEE [2] Wireless LAN specification, and
now encapsulates a number of task groups which have made several
advancements on the specification.
Like the now widely recognised WiFi [3] standard (802.11b [4]), it
operates in the 2.4GHz ISM [5] band, however it only provides 1Mbps
and 2Mbps speeds (using BPSK [6] and QPSK [7] modulation
respectively). Many cards and access points are still available
"after-market" (and for very low prices), however 802.11b [8] is more
widely accepted.
The 802.11 [9] IEEE [10] working group encapsulates the following
standards:
802.11a [11]
54Mbps WLAN [12] in the 5GHz ISM [13] band
802.11b [14]
11Mbps WLAN [15] in the 2.4GHz ISM [16] band
802.11c [17]
Access Point [18] bridging
802.11d [19]
Extensions to operate in additional regulatory domains
802.11e [20]
Quality of Service (QoS [21])
802.11f [22]
Inter Access Point [23] Protocol (Roaming [24]!)
802.11g [25]
54Mbps WLAN [26] in the 2.4GHz ISM [27] band
802.11h [28]
Spectrum Managed 802.11a [29] (SMa [30])
802.11i [31]
Enhanced WLAN [32] security
The 802.11 [33] working group website is located at
http://grouper.ieee.org/groups/802/11/ [34].
Note that 802.11b+ [35] is NOT an IEEE [36] standard, but is also
commonly being used, and is compatible with 802.11b [37] equipment.
