How to use the 5G cellular modem
A simple connection
This section describes some of the scenarios you can use the 5G cellular modem for. For step-by-
step instructions, see
"Configuring a 5G modem using a the ‘wwan0’ interface" on page 10
In this example the office LANs connect to the Internet via a 5G internal modem via the ‘

A backup and resiliency connection
5G mobile broadband provides a high performance solution for connecting rural or remote offices to
the corporate network - ensuring they enjoy the same full access to on-line company resources and
applications as those connected locally or over wired networks.
Installing 5G SIM cards from two different carriers enables a resilient business solution, with backup
of inter-branch links, as even if the 5G signal from one carrier fails, the device can automatically
connect to the alternate carrier using the second SIM. This ensures always-on access and
connectivity right across all company locations.
