2.9 WLAN
The IEEE802.11 b/g WLAN is operable with integrated WLAN module (model dependant). The
IEEE802.11 b/g standard utilizes 2.4 GHz ISM ("Industry Science Medical") frequency band,
which is used for short range wireless communication.
Device Name
On the terminal, the device name used to capture data, with DeviceIoControl function, about the
WLAN driver is "SDIO86861".
2.9.1 Basic Features
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 to operate because
connection problem may occur.
WEP
This is an encryption that uses RC4 method for safe communication. It supports 40-bit (64-bit)
and 104-bit (128-bit).
TKIP
TKIP supports against the weakness of WEP encryption.
AES
Advanced Encryption Standard (AES) is available for encryption method.
Enhanced Encryption
In order to address WEP vulnerabilities, the driver supports WEP key transmission, the new
encryption method TKIP and the AES-developed TKIP. However, AES typically requires
encoding and decoding hardware. The terminal supports AES and is compatible with WPA2.
802.1x Security
This can strengthen authentication and establish a safe and reliable communication via WLAN. In
general, this interlinks with TKIP and AES. It supports PEAP-EAP-MS-CHAP-V2 and EAP-TLS.
