In the whitepaper, Ethernet Direct describes how PoE technology enables the end devices like Wireless Access Point, IP Phone, IP Camera, IP Access Control terminal, RFID reader and other IP-based appliances to get power supply from a Cat-3, Cat-5/5e or Cat-6 LAN cable without extra power connection needed. This technology is particular useful when deploying environments which may not have convenient power source for these equipments, and the extra power outlet may not be feasible and expensive to implement, or when adding these equipments to an existing Ethernet infrastructure without the need to make any modification.
