I want to use the WAP200E-EU in an outdoor café. I have read in its PDF that this AP creates a bubble so I imagine that it sends the signal in 360 degrees but it also says it has a directional antenna. Does this means that you have the option to select one of these two functions? Also there's no available LAN infrastructure to power it with POE. Does this comes with the AC Adapter or do I need a power injector? There's no Adapter in Package Contents in its PDF.
