Power over Ethernet, otherwise known as PoE, and PoE+ provide you with a simple and convenient way to power devices. It eliminates the need for additional wiring installations and helps you save on costs for cabling material, labor and administration. Consolidating power and data transmission to the same cable also allows for faster deployment at the endpoint, particularly to devices at far-off building locations like wireless access points (WAPs), security cameras and sales kiosks. PoE also enables you to centralize power into one location, supporting new smart building controls that adapt to individual users and the Internet of Things (IoT), increasing efficiency and potentially lowering energy costs.
PoE has found success across a variety of applications, including the following examples:
- Wireless access powered by PoE can be installed in areas where there is typically no A/C power outlet and can even be managed through the PoE switch
- IP surveillance cameras using PoE can be located in more remote areas
- High-power PoE can support more camera features, such as pan-tilt zoom and built-in heaters
- PoE supports lighting systems, HVAC control, digital signage, emergency systems and more in smart buildings
- PoE can be used for AV controls in boardrooms, classrooms and auditoriums
- PoE can be used to support digital signage and other interactive devices
- PoE-enabled Voice over IP (VoIP) phones connect offices, universities, airports and more
- Point-of-Sale (PoS) terminals and kiosks in malls, retail, hotels and other areas can be connected to and powered by a single cable with PoE technology
PoE will continue to grow and support a greater range of devices and applications. Without the right cabling and network design in place, though, next-generation PoE may encounter cable heating and connectivity issues that can adversely affect performance. Cabling standards bodies are currently working to expand the potential of PoE while addressing potential safety and performance issues.
