With the ALLNET  Power over Ethernet injectors, you can install your PoE-capable IP end devices such as WLAN access points, VoIP telephones and many more absolutely independently of existing power sockets. This allows you, for example, to select the most ideal installation locations in a building for WLAN access points in terms of radio technology, without having to pay attention to the power cabling. Non-PoE-capable switches can be cheaply "retrofitted" with Power over Ethernet, especially if you only need a few ports with PoE supply.

In reverse you can use the ALLNET PoE splitters. A splitter is basically the exact opposite of an injector. Simply plugging your ethernet cable with PoE into the splitter leaves you with an ethernet port and a power outlet of max 90 watts (depending on what power input is used), ranged from 10V up to 25V.
