Innovative Methods for Geolocation and Communication with UWB Mobile Radio Networks
Summary
In this project CWINS and IWT, a small wireless radio development firm, join forces to design an MB-OFDM UWB system with indoor positioning capabilities.
The main contribution of CWINS is to characterize UWB RF propagation in various environments and develop indoor positioning algorithms that support accurate indoor positioning in an adhoc networking environment. IWT will design the hardware for implementation of the actual communication network. Phase I of this project was completed successfully and we are awaiting the start of Phase II.
In this project Prof. Pahlavan's group used the UWB measurements in 3-6GHz bands to develop a novel model for indoor geolocation. The model was then used for evaluation of indoor geolocation algorithms.
A sample of the application scenario of the project.
