# Overview of Wireless LAN

Wireless LAN allows you to conveniently manage wireless Internet connections on your device. You can set the device's Power Save Mode to make optimal use of the battery under the wireless local area networking environment, view a variety of data related to the current configuration and signal quality. Wireless LAN is designed to work with existing 802.11G devices, such as access points or routers.

To run Wireless LAN on your device, you must have access to the broadband Internet, and the necessary access point or router that emits wireless local area network signals. If you do not have access to the broadband Internet, consult with your ISP (Internet Service Provider) before you attempt to run this utility.

Notes

The availability and range of your device's wireless local area network signals may depend on the number, infrastructure, and objects through which the signal passes.

# Wireless LAN Power Mode screen

The Power Mode screen displays the settings and options about the power being consumed while you are connected to a wireless network. The Power Mode screen has the following fields:

- Power Save Mode
: Wireless LAN consumes a significant amount of power, and will run down your device's battery quicker when the wireless connection is in use. The Power Save Mode option provides three settings. By default, the power save mode is set to the best compromise between battery conservation and signal performance. You can change this by dragging the slider on the indicator bar, or by tapping on the indicator bar itself. The Best Battery setting will conserve more battery power at the expense of performance, while the Best Performance setting will consume more battery power.
- Auto turn off WLAN if not connected.
: If you select this checkbox, the Wireless LAN function automatically turns off if connection fails to be created, which helps to conserve battery power. From the corresponding list, select the time (in minutes) you want WLAN to turn off automatically if no connection is established.

# Wireless LAN LEAP Screen

LEAP is “Lightweight Extensible Authentication Protocol.” This feature of the Wireless LAN Manager allows you to increase the security of your device to ensure that no one can access your network without your permission. By default, the LEAP screen displays data you previously entered, and you can modify it or delete it, if desired, by selecting it and then tapping the Modify or Delete button.

To enter new data, tap the New button. Then enter the appropriate SSID (Service Set Identifier), User Name, Password, Domain, and select an Authentication Type. Most 802.11G access points offer by default a form of authentication called Open System authentication, which is the default Authentication Type setting on your Pocket PC Phone. In this mode, the access point grants approval for any request for authentication. The client simply sends an authentication request frame, and the access point responds with an authentication approval. This allows anyone having the correct SSID to associate with the access point.

Note that for LEAP to work correctly, both the access point and the receiving device (your Pocket PC Phone) must be set with the same SSID, User Name, and Password.
