Connections25ConnectionsWireless LANYour device supports wireless local area network (WLAN).With WLAN, you can connect your device to the internetand compatible devices that have WLAN. For informationabout using your device with other compatible UniversalPlug and Play (UPnP) devices through WLAN, see “Homenetwork,” p. 62.To use WLAN, it must be available in the location and yourdevice must be connected to the WLAN.Features using WLAN, or allowing such features to run inthe background while using other features, increase thedemand on battery power and reduce the battery life.Your device supports the following WLAN features:• IEEE 802.11b/g standard• Operation at a frequency of 2.4 GHz• Wired equivalent privacy (WEP) with keys up to 128 bits,Wi-Fi protected access (WPA), and 802.1x encryptionmethods. These functions can be used only if they aresupported by the network.Wireless LAN connectionsTo use WLAN, you must create an internet access point (IAP)in a WLAN. Use the access point for applications that need toconnect to the internet. See “WLAN internet access points,”p. 26.Important: Always enable one of the availableencryption methods to increase the security ofyour WLAN connection. Using encryption reducesthe risk of unauthorized access to your data.A WLAN connection is established when you create a dataconnection using a WLAN internet access point. The activeWLAN connection ends when you end the data connection.To end the connection, see “Connection manager,” p. 27.You can use WLAN during a voice call or when packet datais active. You can only be connected to one WLAN accesspoint device at a time, but several applications can use thesame internet access point.When the device is in the Offline profile, you can still useWLAN (if available). Remember to comply with anyapplicable safety requirements when establishing andusing a WLAN connection.
