New smart Multi-Gridâ„¢ wireless networks launched


Santa Clara, CA, U.S.A. — (METERING.COM) — March 31, 2010 – Third Generation wireless mesh networking provider MeshDynamics has launched its Smart Multi-Grid™ wireless network technology, which will allow local governments to create powerful new infrastructures combining utility monitoring, metering, and management with a wide range of other key applications including public safety communications, video surveillance, traffic signal controls, and public access WiFi networks.

The thinking behind the technology is that rather than localities rolling out another independent data network to support smart metering that must be individually managed and funded, they can consolidate applications in a single Smart Multi-Grid infrastructure that can support multiple public needs.

Some of the highly desired applications, such as video surveillance, demand high performance in terms of high bandwidth and low latency and jitter. One of the challenges in delivering this type of applications outdoors is the need to connect over long distances with relatively few devices. This can be even more difficult to cost justify if the wireless mesh nodes cannot supply high performance and low latency over many node-to-node links.
Third generation wireless mesh nodes are uniquely well suited to the Smart Multi-Grid wireless network environment, as they add minimal delay and jitter at each node. In addition, sophisticated virtual LAN and other prioritization and security features can provide for the differing needs of each type of traffic, from the low speed access of the utility smart grid to the high demand needs of public safety and video surveillance.
Particularly in suburban and exurban environments, the ability to deliver a connectivity infrastructure for the utility smart grid and other networks over long distances with relatively few nodes allows for a very attractive return on investment. The fact that these nodes operate securely in unlicensed RF spectrums also eases installation and speeds deployment.

MeshDynamics’ partner Technology Associates International Corporation recently successfully deployed its first pilot Smart Multi-Grid wireless network for the military base facilities department at Marine Corps Base Camp Pendleton – an environment functioning like a municipal government in many aspects, with responsibility for utilities and communication for residents and other base infrastructure.
The network is comprised of MeshDynamics MD4000 wireless mesh nodes incorporating a 5.8 GHz network backbone architecture connecting areas of the base utilizing local 2.4 GHz mesh networks. The wireless network covers approximately 23 square miles with the longest transmission link being 4.8 miles long.

The Smart Multi-Grid wireless network provides support for the base’s energy management control system (EMCS) and the automated metering infrastructure. Building automation data is transported to the EMCS to provide constant monitoring of facilities. Technology Associates also implemented the infrastructure to enable real time capability for automated metering providing electric, gas, and water billing data through the wireless network for the base.

“MeshDynamics’ unique technology offered us the high performance over many hops and extended distance that made the base network possible,” commented Anthony Mingus, Technology Associates IT projects manager. “This exceptional performance was key to the success of our deployment.”
MeshDynamics MD4000 wireless nodes are well suited for this military application because they support data encryption with FIPS 140-2 certification. This enabled Technology Associates to provide compliance with Defense Information Systems Agency requirements for wireless network security. Video surveillance of key security locations is being added now to this network, with other applications possible in the future.

A number of additional Smart Multi-Grid wireless networks are in pilot deployments or production today. The technology can be supported by government stimulus monies available for broadband, transportation, and smart grid expansion.
