PoE switches can transmit
Some Cisco WLAN access points and supported a proprietary form of PoE many years before there was an IEEE standard for delivering PoE. PoE switches mainly provides power and data transmission for low-power devices such as VoIP phones, security cameras, wireless APs, remote sensors, and audio devices. These devices are often installed in areas where cabling is difficult, and PoE switches can simplify wiring and. In this configuration, an Ethernet connection includes Power over Ethernet (PoE) (gray cable looping below), and a PoE splitter provides a separate data cable (gray, looping above) and power cable (black, also looping above) for a wireless access point.
