Components Of Your Device; 3G And 4G Networks - Sierra Wireless Overdrive Pro 3G User Manual

Components of Your Device

Your device consists of these main components:
●
Wi-Fi access point
The Wi-Fi access point connects your computers and other Wi-Fi-enabled devices to your device.
●
3G modem
The 3G modem connects your device to the Internet via the 3G (CDMA 1X/EVDO) network (more
widely available, compared with 4G).
●
4G modem
The 4G modem connects your device to the Internet via the 4G (WiMAX) network (newer
technology and faster speeds, compared with 3G).
●
Routing hardware
The routing hardware handles traffic between the 3G or 4G modems, the Wi-Fi access point, and
the Wi-Fi network.

3G and 4G Networks

These wireless networks connect you to the Internet. Depending on your coverage area, you may
have:
●
Both 3G and 4G coverage
●
Only 3G coverage
●
Only 4G coverage.
Your device automatically connects to the fastest network that is available to you. If you have both 3G
and 4G coverage and your connection happens to get disrupted, your device can automatically
switch to the other network. (For more information, see "Configuring the 3G/4G Connection
Preferences" on page 41.)
