Transceiver
Wlan RF implements 802.11b/g WLAN radio for embedded, low-power and small form factor mobile
applications. It conforms to the IEEE 802.11b/g protocols operating in 2.4 GHz band supporting OFDM data
rates of 54, 48, 36, 24, 18, 12, 9, and 6 Mbps as well as CCK data rates of 11 and 5.5 Mbps and legacy data
rates of 2 and 1 Mbps. IEEE802.11e/i protocol extensions are included to implement quality of service (QoS)
and security functions.
