Power over Ethernet (PoE) technology has been transforming how devices are powered and networked. As more devices connect to the Internet and the demand for centralized control grows, PoE’s relevance will increase. Here’s a speculative look at the future of PoE:

1. Higher Power Levels:

  • The IEEE 802.3bt standard has increased the maximum PoE power per port to 90W. In the future, we can expect PoE standards to support even higher power levels, fueling the operation of more robust equipment via Ethernet.

2. Widespread Adoption in Smart Buildings:

  • Smart lighting, HVAC controls, and security systems all stand to benefit from PoE because of the centralized control and power it provides. Buildings of the future might be wired predominantly with Ethernet to cater to various systems.

3. IoT and PoE:

  • The Internet of Things (IoT) will see trillions of devices connecting to the internet. Many of these devices will benefit from PoE, offering a unified solution for data connectivity and power.

4. Integration with Renewable Energy Sources:

  • Buildings of the future might integrate PoE systems with renewable energy sources like solar panels. This would allow for more sustainable and efficient energy distribution within structures.

5. PoE Lighting:

  • LED lighting systems powered by PoE are already on the rise. As technology progresses, we can expect more advanced, adaptive lighting systems that are energy-efficient and integrated with building management systems.

6. Advanced Networking Capabilities:

  • Future iterations of PoE might come with enhanced networking features, allowing for better device management, prioritization, and security.

7. Wireless and PoE Convergence:

  • As Wi-Fi 6 and subsequent standards develop, wireless access points will demand more power. PoE can cater to these needs, ensuring that the latest Wi-Fi technologies function seamlessly.

8. Healthcare Advancements:

  • Medical devices and systems, especially in telemedicine scenarios, could leverage PoE for streamlined operations. This could be particularly valuable in mobile medical units or temporary healthcare setups.

9. Enhanced Safety Features:

  • We might see advancements in PoE standards that focus on ensuring the safety of connected devices, preventing overheating, and offering surge protection.

10. Simplification of AV Systems:

  • Audiovisual setups, such as conference rooms, digital signage, and professional audio systems, could further integrate with PoE for simplified cabling and enhanced control.


The future of PoE is promising, driven by the convergence of power and data requirements in modern devices. As industries move towards more integrated, energy-efficient, and centralized solutions, PoE will be at the forefront of technological advancements, simplifying infrastructure and paving the way for smart environments.
