Tel-Aviv, Israel – (METERING.COM) --- April 24, 2008 – Virtual Extension, a mesh wireless sensor network provider, has introduced the Mobility feature of its wireless fixed mesh sensor network. This capability enables users to move or relocate the network coordinator (or the coordinators – if there are more than one) anywhere within the propagation range of the cell, with no need to make any changes, no re-programming or re-setting, and hence no corresponding delays and no down-time. The same feature also applies to the network nodes.
The mobility can be used in a variety of ways. For example, in AMI mobility can be a key cost factor, as it enables customers to use a single network for either drive-by AMR or fixed network, or to mix different systems in the same network, again without changing the network equipment.
"We learned about the need for mobility from our customers and put it on the original requirements list of our Diversity Path Mesh technology design; so when it was recently required by a customer application, the mobility was there, ready and waiting to be used,” explained Leor Hardy, Virtual Extension’s Chief Technology Officer. “We tested it together with the customer and it worked immediately, exactly as planned.”
The mobility is inherent in Diversity Path Mesh technology, adding to the existing features in the Virtual Extension network product. Diversity Path Mesh, which empowers Virtual Extension products, is a multi-hop, bidirectional communication technology, developed and optimized specifically for wireless sensor networks using mesh topology and operating in the unlicensed frequency ranges.
Diversity 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, the network is flooded 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.
