What is a PoE Switch and How it Can Help Move Your IoT Network Forward

When it comes to setting up an internet of things (IoT) network, the hardware you use is just as important as the software. A Power over Ethernet (PoE) switch can be a great tool to help move your IoT network forward. But what is a PoE switch, and how can it help power your connected devices? In this blog post, we’ll explore what a PoE switch is, its benefits and drawbacks, and how you can use one to power your connected devices. We’ll also look at the various options available and how they might fit into your particular IoT setup.

What is a PoE Switch?

In order to understand what a PoE switch is, it is important to first understand what Power over Ethernet (PoE) is. PoE describes any of several standard or ad-hoc systems which pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both power and data connectivity to devices such as VoIP phones, IP cameras, and Wireless Access Points (WAPs). A PoE switch is a network switch that has been designed to work with devices that use PoE.

There are two main types of PoE switches: those that support the IEEE 802.3af standard, and those that support the newer IEEE 802.3at standard. The 802.3af standard can provide up to 15.4 watts of power per port, while the 802.3at standard can provide up to 30 watts of power per port. There are also a few other standards in development that will increase the amount of power that can be delivered over an Ethernet cable.

The benefits of using a PoE switch are numerous. Perhaps the most obvious benefit is that it can simplify your network by eliminating the need for separate power cables for each device. This can save you money on installation costs, as well as make your network more flexible and easier to manage. Additionally, because PoE switches can provide more power than traditional Ethernet switches, they can be used to connect devices that require more power, such as high-powered WAPs

The Different Types of PoE Switches

There are three main types of PoE switches: unmanaged, managed, and smart. Unmanaged PoE switches are the most basic and are typically used in small networks. They’re easy to set up and don’t require any configuration. Managed PoE switches give you more control over your network. You can configure them to prioritize certain types of traffic or restrict access to certain devices. Smart PoE switches are the most advanced type of switch. They offer all the features of a managed switch, plus additional features like Quality of Service (QoS) and bandwidth management.

The Benefits of a PoE Switch

One of the key benefits of a Power over Ethernet (PoE) switch is its flexibility. Unlike a traditional network switch, a PoE switch can provide power to connected devices through the Ethernet cables. This can be used to power IP cameras, VoIP phones, wireless access points, and other low-power devices that don’t require a lot of power. This can save you money by eliminating the need for separate power adapters and outlets for these devices.

Another benefit of a PoE switch is that it can simplify your network wiring. By using Ethernet cables to both power and connect your devices, you can reduce the amount of cabling needed for your network. This can make your network installation faster and easier, and it can also save you money on cabling costs.

Finally, PoE switches can offer increased reliability for your network. Power over Ethernet delivers power more efficiently than alternative methods like AC adapters or batteries. This can help to prolong the life of your network components and reduce repair or replacement costs.

How to Choose the Right PoE Switch for Your Needs

There are a few key factors to consider when selecting a PoE switch for your needs. The first is data rate: how much data do you need to move across the network? The second is port density: how many devices will be connected to the switch? And the third is power budget: how much power can the switch provide to each device?

PoE switches come in a variety of data rates, from 10Mbps to 10Gbps. If you have a need for high-bandwidth applications, like video or audio streaming, you’ll want a switch with a higher data rate. For smaller networks, or those with less data-intensive applications, a lower data rate may suffice.

Port density is another important consideration. If you have a lot of devices that need to be connected to the network – like computers, printers, and IP phones – then you’ll want a switch with more ports. Some switches have as many as 48 ports, which should be enough for most small-to-medium sized networks.

Finally, you’ll need to consider the power budget of the switch. Most PoE switches can provide up to 15W of power per port, but some only provide 12W or less. If you have devices that require more than 15W of power – like PTZ cameras or Access Points – then you’ll need to look for a switch with a higher power budget.


PoE switches are a great way for IoT networks to move their technologies forward. They can provide multiple streams of power and data, making it easier to scale up your network as needed. PoE switches come in varying sizes and levels of power, so you can find the right one that fits your specific needs. Additionally, most PoE switches offer security features that make sure that only authorized users have access to certain parts of the network or device information – adding an extra layer of protection for your system. With its various benefits and capabilities, investing in a PoE switch is definitely worth considering if you want to take your IoT network further.
