ABSTRACT:
This invention relates to a system (3) and method for monitoring the location of a mobile network unit (9) in a low-power localised wireless communication network (10) such as a wireless personal area network (WPAN). The WPAN could be a ZigBee network. The system (3) comprises a localised wireless communication network (10) having a control unit (5), a plurality of fixed network units (7) and a plurality of mobile network units (9). The mobile network units (9) transmit identification signals and two or more fixed network units (7) receive the identification signals directly and calculate the strength of the identification signals. This information is transmitted to the control unit (5) where the control unit processor calculates with a high degree of accuracy the position of the mobile network unit (9). It is possible to track and plot the location and movement of one or more mobile network units.
