bandwidth signal. UWB is an old, though not yet mature technology with the potential
to impact significantly on traditional ways of managing the spectrum.
Some applications of UWB are in:
- Short-range radio;
- High speed (ten Mb/s) WLAN's;
- Precision geo-location systems;
- Industrial RF monitoring systems;
- Collision avoidance systems;
- Motion and intrusion detection radar;
- Automobile and aircraft proximity radar and precision landing systems;
- Subsurface or ground-penetrating radar.
Of these applications, two offer opportunities for near-term commercialisation and are
therefore fitting candidates for an eTen application.These applications are based on the
ability of UWB to overcome the inherent limitations of narrowband communication in
in-building and cluttered environments, and UWB's known and tested localisation and
positioning application.
Current approaches in the cultural heritage field are mostly based on wireless or
infrared hand-held devices. There has been speculation and experimentation with the
use of normal GSM (Global System for Mobile communication) technology, sometimes
calling directly to an individual's number. For the most part these approaches have been
less than successful. While galleries are often open spaces allowing for the free use of
such technology, historical sites, particularly those with outdoors environments, or
closed locations such as tunnels and galleries offer distinct challenges to the current
technology.
In the travel, tourism and cultural heritage market there is a need for cheap, efficient
and easy-to-use handheld devices that allow the user to access additional information
about a historical object, a statue, a building or in the case of museums and galleries an
exhibit. One difficulty of a `taped' message system is that the user has to identify the
object of interest, and then input a code to receive the relevant message.The user of a
hand held device in a museum is fed the information on the exhibit automatically when
he or she is in front of the specific exhibit, determined through the positioning abilities
of the technology.
An added advantage of the system is that from a security standpoint the museums also
know who is where in each room thanks to the localisation application of the technolo-
gy.This allows a passive security system to monitor the progress and the location of visi-
tors.The application has great market potential.The use of a positioning and localisation
application to identify where individuals are in buildings allows institutions to ensure that
security has not been breached, or that individuals are not attempting to enter secure or
off-limits areas.
Another interesting application of the positioning and localisation abilities of UWB is
in transportation and logistics, where it can be used to determine the location and the
movement of specific shipments that are on rail cars, trucks or in warehouses. If UWB
transmitters are placed inside containers, the location and the shipments of all of these
containers within a large container yard can be determined almost instantly. Beyond the
