PoE Switch vs PoE Injector: Why Choose PoE Switch to Build Wireless Networks?

Power over Ethernet (PoE) technology has revolutionized the way we build wireless networks by allowing data and power to be transmitted over the same Ethernet cable. By utilizing existing twisted-pair Ethernet infrastructure, PoE allows power devices (PDs) such as IP cameras and wireless access points to receive power without requiring any additional modifications to the infrastructure.

You can refer to resources such as the Demystifying PoE Network: Features, Standards, Types, and Common FAQs guide to get more detailed information. When it comes to implementing PoE technology, there are two main options: PoE switches and PoE injectors. In this article, we will explore the differences between these two options and explain why a PoE switch is often the better choice for building wireless networks.

What Is A PoE Switch?

A PoE switch is a network switch that has built-in PoE functionality, allowing it to provide power to connected devices directly through the Ethernet cable. This means that you can connect PoE-enabled devices such as IP cameras and wireless access points directly to the PoE switch using Ethernet cables, and the switch will automatically provide power to the devices without requiring any additional equipment.

What is A PoE Injector?

A PoE injector is a device that adds PoE functionality to non-PoE network switches or routers. You connect the injector between the non-PoE switch and the PoE-enabled device, and it injects power into the Ethernet cable to provide power to the device. This requires an additional step in the installation process, as you need to connect the injector to both the device and the non-PoE switch.
