PoE technology itself does not require WiFi, but PoE technology can be used to power WiFi devices.
PoE (Power over Ethernet) technology is a technology that transmits data and power simultaneously over Ethernet cables. It allows network devices to receive power and data over a single Ethernet cable. PoE technology is mainly used to provide power to network devices, rather than directly providing WiFi signals.

However, PoE technology can be used to power WiFi devices. With PoE power supply, wireless access points can get power directly from the network switch. This means that no additional power cables are required.
This not only simplifies the installation process, but also reduces the need for wiring. This means that network deployment is more flexible and efficient. For example, wireless access points can be installed anywhere there is an Ethernet connection. This includes corners of buildings or places where it is difficult to wire, thereby optimizing network coverage.
Therefore, although PoE technology itself does not require WiFi, it can be used to power WiFi devices. This supports the deployment and operation of WiFi networks.
