The Evolution of PoE: From PoE to PoE+ and PoE++

Power over Ethernet (PoE) technology has transformed the way we power and connect devices in the digital age. By delivering power and data through a single Ethernet cable, PoE eliminates the need for separate power supplies and simplifies installation. Over time, PoE has evolved to meet the increasing demands of power-hungry devices. We will explore the evolution of PoE, from its initial introduction to the enhanced capabilities of PoE+ and PoE++.

The Beginning of PoE:

PoE was first introduced in 2003 that allowed both power and data to be transmitted over Ethernet cables. With PoE, devices such as VoIP phones, wireless access points, router and IP cameras could be conveniently powered and connected using a single LAN cable, simplifying installation and reducing costs. The initial PoE standard delivered up to 15.4 watts of power per port, providing sufficient power for a wide range of devices.

The Advancement to PoE+:

As technology advanced and devices became more power-hungry, the need for higher power output became apparent. In response, the PoE+ standard, also known as IEEE 802.3at, was introduced in 2009. PoE+ increased the power output per port to up to 30 watts, effectively doubling the power capacity of the original PoE standard.


The higher power output of PoE+ opened up new possibilities for powering devices such as pan-tilt-zoom (PTZ) IP cameras, video conferencing equipment, and advanced Wi-Fi access points. PoE+ not only provided more power but also introduced improved power management capabilities, allowing devices to negotiate and request the power they required, ensuring optimal power delivery.

The Emergence of PoE++:

With the proliferation of power-hungry devices and emerging technologies, the need for even higher power delivery capabilities became evident. In response, the PoE++ standard, also known as IEEE 802.3bt, was introduced in 2018. PoE++ pushed the boundaries of power delivery, providing up to 60 watts or even up to 90 watts per port.


PoE++ was a significant leap forward, enabling the power delivery required by devices such as high-performance IP cameras, lighting fixtures, POS (Point of Sales) Kiosk and even thin clients and small form-factor PCs. This enhanced power capability expanded the applications of PoE, allowing for more versatile and efficient deployments in various industries.

Comparison of PoE Standards:

The following table provides a comparison of the key features and power delivery capabilities of different PoE standards:

As the table demonstrates, each iteration of PoE standards has brought significant advancements in power delivery capabilities, enabling the support of increasingly demanding devices. This evolution has opened up new possibilities for deploying a wide range of powered devices in various industries, including surveillance, telecommunications, hospitality, and smart buildings.

Benefits and Considerations:

The evolution of PoE standards has brought numerous benefits to the industry. First and foremost, PoE eliminates the need for separate power cables, reducing installation complexity and cost. It enables flexible device placement, as devices can be powered and connected in locations where power outlets may be limited or unavailable. This flexibility has proven particularly valuable in retrofitting existing buildings or deploying devices in challenging environments.


While the evolution of PoE has brought significant benefits, there are considerations to keep in mind. Higher power levels require careful planning and design to ensure that the network infrastructure can handle the increased power demands. It is essential to select PoE-compatible devices and use appropriate cabling that can support the power requirements. Additionally, PoE devices generate heat, and adequate ventilation and cooling must be provided to prevent overheating and ensure optimal performance.
