Why RF mesh?
Proven in implementations around the World, significant advantages of RF mesh network over other wired and wireless network solutions
Ultimately, technology agnostic – need for reliable data delivery at lowest cost
Selected RF mesh from Eka Systems for lowest estimated cost of ownership
Eka Systems Inc.
Leader in wireless mesh AMR solutions for utilities and energy service providers.
Eka’s innovative mesh networking technology, EkaNetTM, is the most advanced and feature-rich networking platform on the market today.
Applications include utility-scale advanced meter-reading systems and energy-management systems.
Organizations using Eka Systems technology include utility companies, original equipment manufacturers (OEMs), and systems integrators.
About the provider of the solution
True RF mesh AMI
Self organizing – no manual network node provisioning
Ad hoc – no manual network hierarchy assignment
Peer-to-peer – no multiple node types, such as coordinator, router, end device, etc.
Self healing & redundant – distributed intelligence to re-route
Multi-hop: no hop limits, no meter to gateway mapping
RF system operating at 2.4 GHz Reliability of Bluetooth – stable,
proven, robust License free band in Russia 20 milliwatts of transmit power
– range of 500m in free space External antenna options add
flexibility
Connectivity
EkaNetTM architecture
EkaNetTM is fully Internet-enabled, providing access
to the local wireless network throughout the
world. The flexible, scalable architecture is sophisticated enough to
handle the rigorous requirements of industrial
and commercial environments, as well as ideally suited to very low-
cost residential networking applications

No hard limit of meters per gateway (1400+ in deployment)
Multi-tier systems security Gateway redundancy – each node
can go to multiple gateways Option to add battery nodes for
multi-utility metering Easy-to-install in any kind of meter
Technical highlights
1,427,224 residential customers
1,982 employees 70 offices – payment centers Annual consumption (2005)
2,995 million kWh Annual turnover (2005)
400 million Euro
Company facts
Typical building
Gateway - 1
Relays - 3
Meters - 166
Install time – 2 hours Install team – 3 electricians
Bidirectional (demand reset, remote upgrades)
Under-the-glass – vandalism Time synchronization (accurate time of
use) Redundant data storage at meters and
gateways 128 bit encryption Easy to install (no need for highly
qualified technicians) Easy to service (few highly qualified
engineers)
Important system features
No limitation on number of hops
No network addressing for nodes
No hierarchy in network Any node to any gateway No hard limit on nodes to
gateway
Simplified planning
Total cost of ownership often missed in AMI decisions
Corporations with only a few thousand employees maintain large IT departments to manage data communications
The true cost of installing, managing and maintaining a network of several hundred thousand AMR points is not well understood or fully appreciated by many utilities
AMI cost of ownership
Self-configuring system leads to rapid and cost effective installation
Self-organization features of system lead to significant cost savings in operating and maintaining system over useful life
Cost of installing, operating and maintaining large AMI networks is significant and not well understood by utilities
Independence from meter manufactures grants meter multi-brand AMI networks
