•The information is then transferred from the Bluetooth part of the MultiModem EDGE to the modem part of the device.

•The modem then wirelessly transmits the data through the EDGE network tower to the data acquisition server via the Internet.

3.Using a Bluetooth-Enabled PDA to Access the Internet

•To access the Internet, a Bluetooth-enabled PDA connects to the Bluetooth part of the MultiModem EDGE.
