A. B. C. D.A.
An access point is a networking device used to extend the wireless network coverage area. It requires power to function, and there are different methods to provide power to an access point.
A. POE Injector - Power Over Ethernet (POE) is a technology that allows power and data to be transmitted over a single Ethernet cable. A POE injector is a device that injects power into the Ethernet cable, allowing the access point to receive power and data simultaneously. This method eliminates the need for a separate power cable, making installation more straightforward and convenient.
B. Switch - A switch is a networking device that connects multiple devices and enables communication between them. Some switches support POE and can provide power to connected devices, including access points. This method is similar to using a POE injector, but instead of a separate device, the switch provides both power and data over the Ethernet cable.
C. Repeater - A repeater is a device that extends the range of a wireless network by receiving and retransmitting signals. It does not provide power to the access point but can be used in conjunction with a POE injector or switch to extend the network's coverage area.
D. Modem - A modem is a device that connects a computer or network to the internet. It does not provide power to the access point and is not used to extend the network's coverage area.
In summary, A POE injector or a switch would provide power to an access point, while a repeater and modem would not.
