3.2 Wireless LAN (WLAN) Interface
The W3x terminals act as wireless Access Point (AP) supporting IEEE
802.11b/g standards.
IEEE 802.11b operates in the unlicensed 2.4 GHz band and can
theoretically achieve 11 Mb/s. In practice, throughput around 25 Mb/s is
more realistic.
The WLAN interface can be configured to run in combined b/g mode
(supporting 802.11b and g clients at the same time) or as b-only or g-only.
The b-mode-legacy is also supported.
The transmit power is configurable and is limited to maximum 20 dBm.
For wireless security the W3x terminals support WEP, WPA-PSK, WPA2-
PSK and MAC Association Control.

center frequencies:
