Ultrawideband Radio Systems

Ultrawideband (UWB) radio systems transmit information using trains of very short radio pulses. The resultant RF signal often occupies several GHz of radio spectrum, although usually the spectral power density of the signal is very low.
Using UWB techniques, it should be possible to build in-building location systems that have near-Bat-level positioning accuracy, but much lower infrastructure requirements. We're working with a major manufacturer of UWB chipsets to use the expertise we've gained in building and deploying systems like the Active Badge and the Bat to apply UWB methods to the area of location-aware computing.
We're also interested in wireless LANs based on UWB technology, and hybrid systems that combine positioning and data delivery via UWB.
