An indoor access point can only be used indoors. These WiFi points aren't waterproof, so you can only use them in a covered environment. Do you want coverage throughout an entire building? Connect multiple access points from the same series to one another to increase the coverage. This way, you'll have WiFi reception in an entire house, office building, or warehouse. Indoor access points with PoE are powered via the network, so you don't need a separate power cable anymore. This makes providing your entire building with WiFi even easier.
