Project Summary:

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 meters in Virtual Extension’s mesh network operate on standard lithium batteries, designed to last for seven years.
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.
