Hello The access point must be supplied with power via PoE, that is correct. However, a PoE-capable switch does not necessarily have to be used, a PoE injector that complies with the 802.3af (PoE) or 802.3at (PoE+) standards is also sufficient, for example: Ubiquiti U-POE-AF (PoE Injector) If the AccessPoint is supplied with an 802.af device, it must be ensured that the PoE output integrated in the AP no longer functions, or that this output is only operated as a "normal" network output without PoE. When operating with one of the suggested switches, the "small" one is sufficient without any problems - I also operate the device with the 60W switch: Ubiquiti US-8-60W At least for commissioning, the installation of the Unifi Network Controller (https://www.ui.com/download/unifi ) on a PC is necessary. If you want to use advanced features of the Unifi world, it is also necessary to have the controller software running all the time. If you don't have a PC running all the time, an alternative is the Cloudkey which provides the controller software: Ubiquiti UniFi Cloud Key (Network Accessory)

No, the AP cannot be used as a repeater. A controller is also required to administer the AP.
