AMRON Technologies Inc. has announced the successful testing and deployment at multiple sites of its Bluetooth-enabled advanced metering platform for C&I customers. Bluetooth enables wireless communications via short-range radio modules that operate at a frequency of 2.4 to 2.48 GHz. The signal uses a spread spectrum, frequency hopping, full-duplex signal at up to 1,600 hops per second, creating time slots of 625 milliseconds in duration. Security is achieved through a 128-bit encryption process.
By employing Bluetooth-enabled systems throughout its service territory, a utility has a wireless network that opens to the door to a number of new applications, including use as a host for two-way communications, SCADA, and demand-side management. When equipped with a Bluetooth chip set, AMRON's underglass communications interface board enables up to 64 C&I client meters located within 100 feet to be read directly by one host meter.
Meter networks using AMRON's Bluetooth-enabled hardware are fully interoperable, allowing for streamlined communications between various meter types from different manufacturers.
