■ Connectivity
You can connect the phone to compatible devices, using an infrared, or a USB
data cable (CA-53) connection. You can also define the settings for EGPRS or
GPRS dial-up connections.
WLAN/Wi-Fi
Note: Some places, like France, have restrictions on the use of wireless
LAN. Check with your local authorities for more information.
This device can detect and connect to a wireless local area network (WLAN)
through call over local access (UMA). This 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. Since this device was specially designed to detect and connect
to WLAN/Wi-Fi, the proper settings should already be configured in your phone.
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 functionality 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.
A WLAN/Wi-Fi connection is established when you create a data connection
using a WLAN/Wi-Fi access point. The active WLAN/Wi-Fi connection is ended
when you end the data connection.
Features using WLAN/Wi-Fi, or allowing such features to run in the background
while using other features, increase the demand on battery power and reduce the
battery life.
