A wireless remote telemetry system which uses low-cost remote communication devices operating on existing wireless communication systems in order to provide real-time reading and control of remote devices. In an embodiment applicable to utility service, consumption of electrical power among a population of customers is measured by a utility metering system having a wireless communication capability. The metering system comprises a remote metering unit which communicates with a central controller over existing wireless communication systems, such as cellular base stations, using existing communication standards. The remote metering unit transmits various messages over a shared random access channel to a central controller. The central controller transmits messages to the remote metering unit over a paging channel. The remote metering unit may operate in a half-duplex mode only. Furthermore, the remote metering unit may provide a gateway to advanced consumer services at the remote location. |

DETAILED DESCRIPTION The present invention is a novel and improved wireless and remote telemetry system which uses low-cost remote communication devices operating on existing wireless communication systems in order to provide real-time reading and control of remote telemetry devices.
For example, in an embodiment applicable to utility service, consumption of electrical power among a population of customers such as residential homes and commercial buildings, is measured by a utility metering system having a wireless communication capability.
The metering system comprises a remote metering unit which communicates with a central controller over existing wireless communication systems, such as cellular base stations, using existing communication standards.
The remote metering unit transmits various messages to the central controller according to a predetermined schedule which may be remotely set and adjusted by the central controller.
The messages that the remote metering unit transmits to the central controller include utility consumption readings and fault status indications.
These messages are transmitted over a shared random access channel.
The central controller transmits messages to the remote metering unit over a paging channel, providing control functions such as setting the reporting interval of the remote metering units, and acknowledging receipt of messages from the remote metering unit.
The remote metering unit may operate in a half-duplex mode only, thus eliminating the need for more costly components such as a duplexer which are required for full-duplex operation.
The system also may provide various advanced services such as delivering real-time rate information to the remote metering unit to shift demand during peak hours, remote notification of the building owner upon a fault condition in the utility service or metering system, and real-time control functions such as load balancing in order to minimize peak usage.
The system also provides various techniques to manage the reporting load on the system during peak reporting times, such as during a widespread blackout
