How Poe Works

The working principle of Poe is to provide the raw power required for the operation of the access point through a (LAN) network cable. There is no need to connect the power cord separately. Many enterprises have begun to use Poe to reduce the cost of establishing wireless local area networks, as using Poe technology can greatly save the huge cost and complex wiring of purchasing and installing a large number of power sockets and cables, and ensure reliable power supply. In addition, Poe can also allow IP phone users to continue using the phone's functions in the event of a power outage, truly achieving the goal of uninterrupted calls during power outages.

The working principle of Poe is to allow the DC power supply to use unused lines in the CAT5 connection line to transmit electrical energy. It also has two functions: data transmission interface and power cord. If the remote AP adopts PoE, it will make the system architecture simpler, greatly reduce cable consumption, make maintenance easier, more convenient, and reduce costs. Moreover, Poe combines stability and security, as well as remote monitoring capabilities. It does not require an adapter. It can be supplied with 110V or 220V voltage for general use. Therefore, in the future, more Ethernet connection terminal products will apply PoE technology.
