Using WiFi 802.11 I'm trying to build WiFi hotspot fingerprints based solely on radio signal strength and mac id. Now I'm wondering: Would it be possible to know the position of hotspot neighbors in line of sight in order to map their position and build more accurate fingerprints?
I found, surfing around, that some papers have been written about measuring Angle of Arrival (AoA) of signals, so does anyone know of a library or tool (c/c++/java... other) that determines the hotspot position based on this?
thx
