Union, NJ, U.S.A. and Tel-Aviv, Israel --- (METERING.COM) --- February 28, 2008 – SATEC, a provider of energy management solutions, and Virtual Extension, a mesh wireless sensor network provider, have announced the deployment of a wireless mesh automatic meter-reading (AMR) system in the Mamilla quarter of Jerusalem. In this joint project, SATEC will provide the back-office and billing applications, while Virtual Extension integrates the meters with its Diverse Path Mesh technology-based products, creating a fixed wireless network.

Mamilla is a modern residential and commercial area, a mixture of contemporary architecture and historic structures. These complex structures, made of heavy stone and reinforced concrete with narrow corridors between them, pose a formidable challenge for wiring, as well as for ordinary wireless networks. As the water metering system in Mamilla is installed in the basement floors, the propagation between meters on the various floors has proved to be too demanding for conventional wireless solutions, and a GPRS solution would be too expensive due to the recurring monthly costs.

The deployment of the SATEC and Virtual Extension network exceeded the requirements of both reliability and robustness for the Mamilla compound. The meters in Virtual Extension’s mesh network operate on standard lithium batteries, designed to last for seven years.

"This is a normal benefit of Virtual Extension’s robust design, which proves itself in all our wireless network applications” explained Yariv Oren, Virtual Extension’s Chief Executive Officer. "Working together with SATEC enabled the delivery of a creative and complete solution. We look forward to expanding our cooperation to provide successful mesh solutions in all the advanced metering and wireless sensor network ranges.”

Virtual Extension’s patented technology approach, the Diverse Path Mesh, ensures that each transmission is relayed by the nodes surrounding it. Instead of investing in computing power to choose the best radio path and then instruct specific nodes, Virtual Extension floods the network with the data in dozens of propagation paths, eliminating the need to rout and manage, thus increasing robustness and range and connecting thousands of nodes per network.

SATEC’s wide range of advanced, highly reliable and user-friendly monitoring instruments is complemented by its advanced data analysis software and on-line energy management service, eXpertpowerTM. Via the Internet, eXpertpower provides users with a complete set of tools for billing, monitoring and analysing entire power systems, accessible from anywhere.

The synergy between Virtual Extension’s wireless network and SATEC’s back-office and billing enables robust end-to-end AMR/AMI solutions to meet the growing needs for advanced metering.
