3.7 WLAN
The IEEE802.11b WLAN is operable on the models, DT-X11M10RC and DT-X11M30RC. The
IEEE802.11b standard utilizes unlicensed 2.4 GHz ISM (Industry, Science, and Medical)
frequency band, which is used for close range wireless communication.
Device Name
On the terminal, the device name used to capture data for the WLAN driver with
DeviceIoControl function is “GWCF1”.
3.7.1 Basic Specifications
Roaming
This function automatically switches Access-Point in environment where two or more
Access-Points with identical SSID code exist.
Power Saving
This saves the power by automatically turning OFF the power to the integrated WLAN module in
the terminal when communicating does not take place.
AdHoc
This operation mode provides a direct communication between wireless equipments without the
use of Access-Point. Note, however, that the AdHoc mode is not recommended because
connection problem may occur.
WEP
This is an encryption function that uses RC4 method for safe communication. It supports 40-bit
(64-bit)/104-bit (128-bit).
TKIP
TKIP is supported to combat the weakness with WEP encryption.
IEEE802.1x Security
This can strengthen authentication and establish a safer WLAN. Usually, this is interlinked with
TKIP. It supports WPA PSK and WPA EAP (PEAP-EAP-TLS, PEAP-MS-CHAP-V2, MD5, and
EAP-TLS.
