Abstract: A method and apparatus for two-way telemetry is provided. For one embodiment, a telemetry interface module may receive data regarding the strength of transmitted signals. The telemetry interface module may transmit a query message to another telemetry interface module and receive a reply message containing received signal strength indicator (RSSI) data for the query message as received by the other telemetry interface module. For one embodiment, a telemetry interface module may adjust a transmission power level. For one embodiment, a telemetry interface module may select between a plurality of antennae for reception and transmission.

Abstract: A wireless end device is provided. For one embodiment, a wireless end device may comprise a sensor integrated with a telemetry device. The wireless end device may monitor the sensor for a predefined condition, and transmit a message to a controller in response to detecting the predefined condition. For one embodiment, the sensor may be a vibration or level switch, and the predefined event may be a switch closure. For another embodiment, a control system is provided comprising a controller and one or more wireless end devices.

Abstract: A wide-area remote telemetry system which monitors and controls remote devices by means of a information control system. The system uses a plurality of sensor interface modules which constantly monitor devices for triggering events. The sensor interface modules transmit information to at least one data collection module which gathers, process, stores and transmits information to a host system via standard external communication systems. The host module receives, records, processes, and transmits information to the network. The information may then be transmitted to customers or may be accessed by customers as desired.
