Three anechoic chambers?

Important instrument, different

usages

CorteXlab: Cognitive Radio and

physical layer of wireless communications

LEAT: high precision antenna

propagation

SLIDE 17

Joint Position and Orientation Estimation

Hot topic, several applications
Smart Home, Geo-fencing, VR, Indoor

navigation, personal drones, etc.

On commodity Wi-Fi infrastructure
Accuracy requires calibration
R2lab provides controlled conditions to

calibrate
