■ WLAN/Wi-Fi
Important: Always enable one of the available encryption methods to
increase the security of your wireless LAN connection. Using encryption
reduces the risk of unauthorized access to your data.
Note: Some places, like France, have restrictions on the use of wireless
LAN. Check with your local authorities for more information.
Your device supports voice calls over the internet (internet calls) and attempts
emergency calls primarily over cellular networks. If an emergency call using cellular
networks is not successful, your device attempts an emergency call through your
net call provider. Due to the established nature of cellular telephony, you should
use cellular networks for emergency calls, if possible. If you have cellular network
coverage available, make sure that your cellular phone is switched on and ready to
make calls before you attempt an emergency call. The capability for an emergency
call using internet telephony depends on the availability of a wireless local area
network (WLAN) and your net call provider's implementation of emergency call
capabilities. Contact your net call provider to check the internet telephony
emergency call capability.
This device can detect and connect to a WLAN through call over local access. This
unlicensed mobile access (UMA) technology allows a seamless handoff of mobile
voice and data from a wide area cellular network to WLAN or wireless fidelity (Wi-Fi),
so it is possible to connect at a high speed to the internet from virtually anywhere.
Before you can start using UMA, you must first obtain a UMA account with your
service provider. The proper settings may already be configured in your phone
because this device was specially designed to detect and connect to WLAN/Wi-Fi.
For more information, contact your service provider.
If you move the device to another location within the wireless LAN and out of range
of a WLAN/Wi-Fi access point, the roaming function can automatically connect
your device to another access point that belongs to the same network. As long as
you remain within range of access points that belong to the same network, your
device can stay connected to the network.
