How does 802.11a differ from 802.11b/g and what are the advantages of 802.11a?
While 802.11b and 802.11g operate in the relatively congested 2.4 GHz band, 802.11a operates in the much less congested 5 GHz-UNII band, and with its 12 non-overlapping channels, allows for deployment of much larger WLANs with a substantial increase in the amount of wireless clients served. Conversely, the range of a single 802.11a station is much smaller than 802.11b or 802.11g, due to the higher free-space path loss experienced in the 5 GHz band. The major disadvantage of 802.11a is in the fact that these devices are substantially more expensive than 802.11b/g.
