Abstract

A plurality of cooperative telemetry systems is disclosed in which each telemetry system comprises a plurality of remote telemetry transmitters to intermittently transmit short duration messages indicative of the status of sensors associated with the remote telemetry transmitters and at least one telemetry collection unit including a radio transceiver. Each telemetry collection unit forms a node in a wireless network in which telemetry collection units cooperate with each other in order to increase reliability and lower the average cost of each telemetry system. Such network can communicate with a remote central monitoring station via one or more network interface units connected to a private or public wired or wireless network.
