### **Why Power over Ethernet (PoE) is used in embedded IoT gateways?**

Power over Ethernet (PoE) is a technology that allows power and data to be transmitted over a single Ethernet cable. This makes it a useful tool for embedded IoT gateways, which are designed to connect IoT devices and sensors to the cloud or other networks. In particular, PoE can provide a number of benefits for these devices.

Firstly, PoE can simplify the installation process for embedded IoT gateways. By eliminating the need for separate power cables, PoE can reduce the amount of cabling required and make it easier to deploy these devices in a wider range of locations. This can be particularly useful for applications where space is limited or where it may be difficult to run additional cabling.

Secondly, PoE can increase the reliability of embedded IoT gateways. By reducing the number of components that can fail, such as power supplies, PoE can make these devices more resilient and less prone to downtime. This is particularly important for applications where IoT gateways are used to monitor critical systems or processes.

Finally, PoE can enable greater flexibility and scalability for embedded IoT gateways. By providing a simple and reliable way to power these devices, PoE can make it easier to deploy additional devices as needed, and to scale IoT deployments over time. This can help organizations to stay agile and responsive to changing business needs.

In summary, PoE is an important technology for embedded IoT gateways, as it can simplify installation, increase reliability, and enable greater flexibility and scalability. These benefits make PoE an attractive option for organizations looking to deploy IoT gateways in a wide range of applications and environments.
