4.3.1.5 Cellular
This section explains how to set the related parameters for cellular network. The UG87-LW
LoRaWAN gateway has two cellular interfaces, namely SIM1 and SIM2. Only one cellular
interface is active at one time. If both cellular interfaces are enabled, then SIM1 interface
takes precedence by default.
A typical use case would be to have SIM1 configured as the primary cellular interface and
SIM2 as a backup. If the UG87-LW cannot connect to the network via SIM1, it will
automatically fail over to SIM2.
