Fast Indoor Radio-Map Building for RSSI-basedLocalization Systems

7. Juni 2012 | P. M. Scholl, S. Kohlbrecher, V. Sachidananda, K. Laerhoven, J. Meyer This work was funded by the DFG/GRK1362 - Cooperative, Adaptiveand Responsive Monitoring in Mixed Mode Environments.

I Idea: automate the way Indoor Signal Maps are builtI Signal Map: (x , y ) 7→ (r1, r2, ...rn) (wireless signal strength)I RSSI signals of infrastructure via WiFi, Bluetooth, ZigBeeI position+floorplan via handheld Mapping Box (usually done manually)

I Question: How unique is the measured RSSI-vector rx ,y atposition (x , y )? Calculate absolute distance for all positions.
