Explains core concepts related to cellular interfaces, covering foundational information that supports subsequent configuration and operational procedures.
A cellular interface is a network interface that enables wireless communication over a cellular network.
-
Provides wireless connectivity when all wired WAN tunnel interfaces on the device are unavailable.
-
Functions as the primary WAN link for a branch office, depending on usage patterns and supported data rates.
Cellular module and data profile components
The following components are essential for cellular interface operation:
-
Cellular module: Installed in a router to enable LTE connectivity, provides wireless connectivity over a service provider's cellular network, and supports network access for use cases such as branch office connectivity.
-
Data profile: Defines parameters for how the device connects to a cellular network and uses the parameters for communication with the service provider.
