Power over Ethernet

What is Power over ethernet?

POE stand is a wired ethernet local area network implementation technology that allows the electrical current required to operate each device to be carried by ethernet data cables rather than standard electrical power cords and wiring.

PoE which is used in both smart home applications and business premises uses less expensive Ethernet cabling that can transport both power and data instead of electrical wiring, which only supplies power and requires separate wiring for data. PoE transport both power and data over cable, less wiring is required and existing electrical wiring can be reused.

PoE was created in 2003 to support devices such as wireless access points. Individual vendors previously used various forms of proprietary PoE to provide PoE capabilities. Some of these proprietary PoE devices are still in use. PoE installer must locate these older, proprietary devices because they can be troublesome or incompatible with later released standard PoE devices. Today's standard PoE devices make AP installations simpler and more adaptable in ceilings that can wire for electrical power.  

Why should you use PoE?

Power over Ethernet provide numerous benefits to an installation:

  • Saving in time and money -  By reducing the time and cost of installing electrical power cabling. Network cables do not need to be installed by a qualified electrician and can be placed anywhere.
  • Flexibility -  Because they are not tethered to an electrical outlet, devices such as IP cameras and wireless access points can be placed wherever they are most needed and easily repositioned if necessary.
  • It is intelligent and designed to protect network equipment from overloading, uploading, or incorrect installation.
  • Reliability -  Rather than a collection of distributed wall adapters, PoE power comes from a centralized and universally compatible source. It can be powered by an Uninterruptible power supply  or remotely controlled to easily disable or reset devices.
  • Scalability - It is having enough power on the network to make installation and distribution of network connection simple and efficient.
