Abstract (en)
[origin: CA2386388A1] A communication module (36) for an asset (26) to be monitored operates to periodically receive a signal from a monitoring facility (34) via a first wireless communication system (14,20,22), and in response to the absence of the signal at an expected time, communicating with the module via a second wireless system (24,30,32,34). The first system may be a short range system operating inside a limited facility (12), and the second system may be a cellular phone system. The module may include a global positioning receiver (50), so that the module may report its location via the second system to th e monitoring system when it is taken from the transmission range of the first system.
