Power over Ethernet (POE) is a technology that provides both power and data connection to a remote device.
It is a cost-effective method for powering network devices. Described in the IEEE 802.3af standard, PoE enables delivery of power over existing CAT-5 LAN cabling, eliminating the need for running separate power cables.
The applications are numerous, ranging from powering IP Phones, LAN access points, and WiFi switches to RFID readers and network security cameras.
