Some networking equipment (such as the roof-mounted WiFiRanger units) are powered over the ethernet network wire instead of via a dedicated power cord and power supply. This makes wiring much simpler since only a single wire needs to be run to the device. To get the power onto the ethernet wire, a POE injector is used to energize the wire. The WiFiRanger Go has a built-in POE injector on one of its ethernet ports.
