The device has two antennas. One antenna collects data from the sensors, and the other antenna forwards the data to the electrical utility control center over cell phone service. In some systems, powerline sensors may transmit information on the high voltage conductor itself rather than by transmission of a radio signal. [4] [5]
This timely information coupled with analysis can help both utility providers and customers better control the use and production of electric energy, gas usage, or water consumption. AMR technologies include handheld, mobile and network technologies based on telephony platforms (wired and wireless), radio frequency (RF), or powerline transmission.
Typically, the DLR server can be configured to send standard telecontrol frames to the electric utility's SCADA front-end acquisition units. These frames can then be processed for display and calculations by the utility energy management system or distribution management system. Short-term network operation decisions are based on optimized ...
The term smart meter often refers to an electricity meter, but it also may mean a device measuring natural gas, water or district heating consumption. [1], [2] More generally, a smart meter is an electronic device that records information such as consumption of electric energy, voltage levels, current, and power factor.

Many of the nodes are still in the research and development stage, particularly their software. Also inherent to sensor network adoption is the use of very low power methods for radio communication and data acquisition. In many applications, a WSN communicates with a local area network or wide area network through a gateway. The Gateway acts as ...
