Wi-Fi; How It Works - Samsung SGH-T336 User Manual

Wi-Fi

The Wi-Fi menu (Menu 7) enables you to use a Wi-Fi (Wireless Fidelity)
connection to make calls at home using your high-speed Internet service.
Calls made using your Internet connection do not deplete your airtime
minutes.
Note: To use this service, you require a Fido wireless router, high-speed Internet connection and
a Wi-Fi option added to your wireless plan. Contact your service provider for additional
information.

How it Works

As well as your phone's normal operating mode (using GSM radio to
connect to cellular towers), Wi-Fi compatibility also allows use of UMA
(Unlicensed Mobile Access) technology to connect your mobile phone to
your GSM/GPRS services using a Wi-Fi (Wireless Fidelity) connection
between your phone and a wireless router (also known as an "access
point" or "hotspot").
When your phone is within range of your router (approximately 300 feet),
the router handles all calls -- voice calls, Internet browsing, e-mail, text and
picture messaging. When you are not within Wi-Fi range, your phone
automatically switches to the normal cellular network. The switching
process is virtually unnoticeable, whether your phone is in Idle mode or in
the middle of an active call.
Note: Wi-Fi networks operate in the unlicensed 2.4 GHz ISM radio band using IEEE 802.11
protocols, such as 802.11b (11 Mbps) and 802.11g (54 Mbps).
