Router selection depends on the control cabinet, local interfaces, power supply, antenna position and maintenance method.

Cellular WAN at the cabinet

Connect controllers, meters and cameras to the router over Ethernet. Add a switch when more ports or PoE are needed. Check the installation requirements in the site checklist before choosing a model.
