Choosing the Right PoE Standard: PoE vs. PoE+ vs. PoE++

Powering network devices efficiently is a challenge that IT professionals face every day. Whether managing security cameras, access points, or smart building technology, selecting the correct PoE standard can mean the difference between a seamless operation and a network struggling to keep up. PoE, PoE+, and PoE++ offer different power levels, but choosing the wrong standard can result in underperforming equipment or spending more than necessary.

Choosing the Right PoE Standard

You need a network that delivers reliability without waste

Global IT provides the expertise to ensure your infrastructure meets current demands while staying ready for the future. This guide breaks down the differences between PoE standards and helps you make the right decision for your setup.

Why Selecting the Right PoE Standard Matters

Why Selecting the Right PoE Standard Matters

Power over Ethernet (PoE) simplifies network installations by delivering power and data through a single cable. This method eliminates separate power supplies, making setups cleaner and more efficient. However, different PoE standards provide varying levels of power. Selecting the wrong one can lead to underperforming devices or unnecessary expenses.

This guide explains the differences between PoE, PoE+, and PoE++ and provides a straightforward approach to choosing the right one for your needs.

Understanding PoE and Its Function

PoE allows network cables to carry electrical power alongside data. The IEEE 802.3af standard introduced this capability, providing up to 15.4W per port. It works well for devices with low power needs, such as basic security cameras and VoIP phones.

PoE Overview:

  • Devices supported: VoIP phones, simple access points, basic security cameras
  • Ideal for: Small offices, basic networking setups

PoE+: Supporting More Demanding Devices

As network technology advanced, certain devices required additional power. The IEEE 802.3at standard, known as PoE+, increased power delivery to 30W per port. This supports more advanced hardware like pan-tilt-zoom (PTZ) cameras and dual-band wireless access points.

PoE+ Breakdown:

  • Devices supported: HD security cameras, video conferencing phones, stronger access points
  • Best for:Expanding networks, mid-sized offices, enterprises

PoE++: Meeting High-Power Demands

Smart buildings, industrial systems, and large-scale deployments often require PoE++ (IEEE 802.3bt). This standard offers up to 100W per port, divided into two categories:

Type 3 PoE++

 Supplies

60W

per port

Type 4 PoE++

Delivers

100W

per port

PoE++ Details:

  • Devices supported: HD security cameras, video conferencing phones, stronger access points
  • Best for:Expanding networks, mid-sized offices, enterprises

Avoiding Common PoE Mistakes

Insufficient Power Allocation

Connecting high-power devices to a PoE-only switch can result in poor performance or device failure. Always check wattage requirements before installation.

Overpaying for Unnecessary PoE++

While PoE++ supports the most power-hungry devices, most setups do not require that level of power. If your network consists of VoIP phones and basic security cameras, PoE+ may be a better investment.

Ignoring Future Expansion

Networks grow over time. Installing PoE+ today may prevent unnecessary hardware replacements in the future. If expansion is likely, consider selecting a PoE++ switch now.

Comparison of PoE Standards

Understanding the differences between PoE, PoE+, and PoE++ is key to selecting the right standard for your network. The table below highlights key specifications and use cases for each:

How to Select the Right PoE Switch

Use this step-by-step approach to determine the best PoE standard for your network:

  • 1 List all devices requiring power: Include security cameras, access points, and network hardware.
  • 2 Check the power demand for each device: Review manufacturer specifications.
  • 3 Calculate the total power needed: Add up the wattage for all connected devices.
  • 4 Match the needs to the correct PoE standard: Use the comparison table above.
  • 5 Select a switch with extra capacity: Leaving power headroom prevents future issues.
