Local Positioning

This team develops algorithms, software, and hardware for using local wireless systems for positioning and navigation in areas without GPS coverage, such as indoors. Indoor positioning applications can be used, for example, for finding friends, family members, and places in complex indoor areas, such as malls or airports. The technology can be deployed also for tracking material, equipment, and people in industrial solutions. The main aim is to develop low-cost and easy-to-deploy solutions that scale from building level accuracy to less than one meter accuracy.

Research topics

Systems and methods for representing location information indoors.
Direction and distance measurement algorithms on top of existing wireless local connectivity standards, such as Bluetooth and IEEE802.11.
Direction finding antennas for handheld devices and wireless access points.
Methods and tools for community-collected fingerprint data without global coordinate reference.
Visualization of indoor maps and building models.
Indoor routing algorithms.
Sensor-assisted positioning algorithms.
