The proposed thesis project is a second iteration of an earlier project: “Connected Safety Vest for Roadworkers”. The aim is to test the suitability of 802.11-based positioning in confined, irregular spaces (e.g., indoor industrial settings) where satellite positioning is not possible and multi-path and other propagation phenomena affect positioning based only on time-of-flight and angle-of-arrival measurements.

The idea is to follow the logic from beaconing services such as the Cooperative Awareness (CA) basic service and the Vulnerable Road User Awareness (VA) service defined by ETSI, where entities send beacons with Position-and-Time information (PoTI) to make others aware of their presence and dynamics. The medium-, and long-term milestones for the project are:

1. Assess the suitability of 802.11-based positioning to provide <1m accuracy positioning using embedded systems and off-the-shelf network equipment.

2. Develop a system that delivers accurate PoTI with similar requirements to ETSI CA and VA services (i.e., accurate information being sent at rates up to 10Hz)
