Positioning System

GPS can be used indoors, but sometimes it
does not work. Also, the cost of launching
satellites is very expensive. For the
applications of regional positioning, it is too
wasteful. Therefore, people can use the
wireless sensor network concept to develope a
regional positioning system for single area
such as in a campus or a hospital.

Conclusions

Such a platform provides a complete
and versatile system, based on e-textile
and WSN as most innovative
technologies, both to monitor a set of
physiological parameters from several
patients and to locate them (or any other
personnel from the hospital if desired)
within hospital facilities.
