How PoE is Evolving To Support More Power-Hungry IoT Solutions

HomeBusinessHow PoE is Evolving To Support More Power-Hungry IoT Solutions

Power over Ethernet (PoE) is a technology that has been around for decades, but its use has increased dramatically as the Internet of Things (IoT) revolutionized our lives. PoE allows users to power devices directly from an Ethernet connection, eliminating the need for additional power sources. As IoT devices become more sophisticated and require more power, PoE solutions must evolve to meet the demands of these devices. In this article, we will explore how Power over Ethernet is evolving to support the ever-increasing needs of modern IoT solutions. We’ll look at the types of PoE technologies available today, what their power requirements are, and how they can be used in various applications.

What is PoE?

As the Internet of Things (IoT) devices become increasingly sophisticated, their power requirements are also increasing. This is where Power over Ethernet (PoE) comes in. PoE is a technology that allows electrical power to be carried over standard Ethernet cables. This means that PoE-powered devices can be connected to the network without the need for a separate power supply.

PoE has been around for many years and is commonly used to power IP phones, wireless access points, and security cameras. However, the latest generation of IoT devices requires more power than what PoE can provide. As a result, PoE is evolving to support higher power levels. The latest PoE standard, IEEE 802.3bt, can provide up to 100 Watts of power – enough to power even the most demanding IoT devices.

Looking to the future, it is likely that PoE will continue to evolve to support even higher power levels as IoT devices become ever more sophisticated.

The Different Types of PoE

As the Internet of Things (IoT) continues to grow, the demand for power over Ethernet (PoE) solutions that can support more devices and higher data rates is also increasing. To meet this demand, the IEEE 802.3af and 802.3at standards have been developed to provide greater power levels over standard Ethernet cabling.

The different types of PoE are as follows:

Type 1: Power over spare pairs – up to 15.4W per port

Type 2: Power overdata pairs – up to 25.5W per port

Type 3: Enhanced power over data pairs – up to 30W per port

Type 4: High-power over data pairs – up to 60W per port

The Evolution of PoE to Support IoT

As the world becomes more connected, the demand for power over Ethernet (PoE) solutions is increasing. The IoT market is expected to grow from $157B in 2020 to $1T by 2025, and PoE is poised to play a major role in powering these devices.

Today’s PoE solutions are capable of delivering up to 60W of power, but the future of PoE is even more exciting. The IEEE is working on a new standard, 802.3bt, which will increase the maximum power delivery to 100W. This will enable PoE to power a wider range of devices, including 4K displays,access points, and security cameras.

In addition to increased power delivery, the new standard will also improve efficiency and offer other enhancements. For example, it will allow for dynamic power allocation, meaning that devices can draw only the amount of power they need at any given time. This will save energy and reduce costs for businesses that deploy PoE-powered IoT solutions.

The 802.3bt standard is expected to be finalized in 2019, with products hitting the market in 2020. This timeline puts PoE in a position to be a major player in powering the IoT revolution.

Benefits of PoE for IoT Solutions

The growth of the Internet of Things (IoT) is driving the need for more powerful and flexible networking solutions. Power over Ethernet (PoE) is one technology that is evolving to meet the needs of IoT applications. PoE provides a single cable solution for both data and power, which simplifies network infrastructure and reduces installation costs. In addition, PoE can provide a more reliable and robust power delivery than other options, such as batteries or wall adapters.

PoE technology is constantly evolving to support more demanding applications. The latest IEEE 802.3bt standard supports up to 100W of power over Ethernet, which is enough to power even the most power-hungry IoT devices. The new standard also introduces a number of other enhancements, such as increased efficiency and support for higher data rates.

PoE provides many benefits for IoT solutions, including simplified installation, reduced costs, and improved reliability. With the latest 802.3bt standard, PoE can now support even the most demanding applications.


In conclusion, PoE technology is rapidly evolving to support the more intensive power requirements of today’s IoT solutions. Although there are still some challenges that manufacturers and developers face when using this technology, new standards and technologies are being developed every day to make sure that all devices connected over a network can benefit from the advantages offered by Power over Ethernet. As such, it can be expected that PoE will soon become an essential part of any IoT-enabled environment.
