Morgan Hill, CA, U.S.A. --- (METERING.COM) --- June 22, 2010 - The USNAP Alliance has released for public comment its draft 2.0 Specification, which is intended to facilitate connectivity between smart grid devices and universal communication modules installed in a home area network (HAN).

The specification is open for comment by all interested parties over the next 30 days.
 
The 2.0 Specification defines the hardware interface, physical dimensions, data transfer, message and contents for the HAN devices. The root of the specification utilizes the Serial Peripheral Interface (SPI) port found on most chips as the basic transport layer. The card itself is only 1.5 inches square, making it small enough to fit into virtually any energy consuming product.

USNAP cards are already available through traditional channels supporting ZigBee, Z-Wave, RDS, Wi-Fi and FlexNet. The Alliance plans to incorporate powerline and Internet Protocol communication technologies in future specifications,
 
“We’re very excited to offer this body of work encompassing the intellectual development of our members that represent all important facets of the smart grid industry,” said Jon Rappaport, chairman of the USNAP Alliance. “With the completion of the 2.0 Specification, there will be a wide range of HAN products coming to market that utilize the small and inexpensive USNAP solution, supporting both factory and consumer installed scenarios.”
 
The USNAP Alliance is an open industry association developing an industry standard for connecting energy aware consumer products with smart meters.
