Overview
IEEE 802.11 standards were introduced in 1997. Over the past few years,
several different WLAN technologies and standards have been developed to
increase data rates.
This section briefs the IEEE 802.11 standards: 802.11a, 802.11b, 802.11g,
802.11n and 802.11ac.
There are various modulation schemes, data rates, and frequency ranges
contained in the IEEE 802.11 standards family, as summarized in the table
below.
