● Modem: The modem connects your device to the Internet via the best available network
(customizable):
LTE – Newer technology, faster speeds compared with 3G and GSM
3G – CDMA technology, more widely available compared with LTE
GSM – GPRS/EDGE/HSPA/HSPA+, available for international roaming
● Routing hardware: The routing hardware handles traffic between the modem, the Wi-Fi
access point, and the Wi-Fi network.
GSM, 3G, and LTE Networks
These wireless networks connect you to the Internet.
Depending on your coverage area, you may have:
● Only LTE coverage
● Only 3G coverage
● Only GSM coverage (GSM coverage is always roaming)
● A combination of these networks
Your device automatically connects to the fastest network that is available to you. If you have
both 3G and LTE coverage and your connection happens to get disrupted, your device can
automatically switch to the other network. (For more information, see Mobile Broadband
Information and Settings.)
