Did you know there are Wi-Fi access points that don't require an AC adapter? - PHILE WEB

Have you ever thought that the Wi-Fi signal was good in a client's conference room, but there was a Wi-Fi access point on the ceiling/wall? Basically, a Wi-Fi access point emits radio waves in a spherical shape, and it is advantageous to install it high on the wall or on the ceiling. I agree with you on this point, but what about the power supply? A Wi-Fi access point can't function without a fine electronic device, a power supply. However, only the LAN cable is connected to the Wi-Fi access point. I can't find an outlet nearby, and I can't think of a rechargeable one because it's installed on the ceiling... How do you secure a power supply?

Buffalo's corporate access point "WAPM-1266R" that supports PoE It is probably a Wi-Fi access point that supports PoE (Power over Ethernet). PoE-compatible devices can be powered with a single LAN cable, so there is no need to prepare a power supply device such as an AC adapter. Although there are few products that support PoE in Wi-Fi routers/access points for general households, it is becoming an essential function for corporations/offices. Although it requires a switch product (PoE switching hub) that can supply power with a LAN cable, it has the great advantage of being able to install network equipment in places where power supply is difficult or where construction work is required. Wi-Fi routers/access points are not the only products that focus on this advantage. Product variations such as security cameras, IP phones, and small displays are increasing. Aside from home/indoor use, it is certain that there will continue to be a need for PoE in office/outdoor use.
