What is POE Switch?

When the device is connected to the network, it needs two inputs: a power cord and a network cable. PoE is a technology that allows Ethernet cables to transmit power. One of the other advantages of structured cabling is that it can be used to transmit power using Power over Ethernet (PoE) technology. PoE is useful for devices such as wireless network repeaters or IP security cameras because they are usually installed on high walls or ceilings, away from the nearest power outlet. Using PoE means they can use a single Ethernet cable to transmit voice, data, and power.

What Devices Can Use PoE?

PoE provides value for devices and networks that require power but also involve the transmission of data. The number of devices controlled remotely and requiring data is increasing exponentially as companies take advantage of the Internet of Things (IoT). The number of IoT devices connected worldwide is expected to reach 75 billion by 2025!

This rapid expansion of network-connected devices will only increase the importance of PoE technology to most networking infrastructures.

While PoE has numerous applications, the three most common areas of implementation are currently:

• VoIP Phones: VoIP phones are the original PoE devices, and PoE allows a single connection to a wall socket and the ability to power off remotely
• IP Cameras: Security camera technology is constantly evolving, and one of the improvements is the use of PoE, which enables rapid deployment and simple repositioning.
• Wireless: Numerous remote passageways are PoE viable, considering far off situating. RFID readers are additionally PoE viable, which considers simple movement.

A more recent technology that benefits from PoE is smart home automation. This includes LED lighting, heating and cooling systems, appliances, voice assistants, and electric car charging stations.
