New ZigBee module for smart grid applications


Lexington, MA, U.S.A. — (METERING.COM) — June 26, 2008 – MU Net, Inc. (muNet), a provider of Internet Protocol (IP) and other standards-based advanced metering infrastructure solutions including IEEE 802.15.4/ZigBee, has introduced its new WebGate TotalPoint ZigBee module, a stand-alone, high-power IEEE 802.15.4/ZigBee module optimized for advanced metering infrastructure, home area networking (HAN), and remote sensor networks in support of a growing suite of smart grid applications.

The FCC approved WebGate TotalPoint ZigBee Module utilizes Ember Corporation’s EM250 system-on-a-chip (SoC), and consists of a 2.4 GHz, IEEE 802.15.4 compliant transceiver using O-QPSK modulation and an integrated 16-bit XAP2b microprocessor. The TotalPoint ZigBee Module incorporates an external power amplifier resulting in a maximum transmit power of 100mW (20dBm). The module utilizes a ceramic chip antenna which, together with the extended power amplifier and outstanding receive sensitivity of the EM250, results in excellent overall range.

“The TotalPoint ZigBee module was specifically engineered to address the unique needs that AMI and smart grid applications require,” says Josh Schadel, muNet’s Vice President of Engineering. “Specifically, the addition of the external power amplifier significantly increases the effective range of the module, making it the ideal solution to address the diverse, challenging environments that AMI, HAN and smart grid application developers encounter in the field.”

The WebGate TotalPoint Module can run any application code generated for the Ember EM250, and with a footprint of 1.34” x 1.8” is the perfect ‘drop-in’ module for manufacturers of HAN devices, smart grid sensors, and meters, especially those benefiting from extended range. “We designed the TotalPoint ZigBee module to improve economy of scale within our core WebGate TotalPoint AMI platform products,” said Schadel. “But our partners quickly convinced us that the module was immediately useful in a host of other products.”
