AMI
Advanced Metering Infrastructure
We Build 'Next Generation' AMI systems
Reliable, Scalable and Cost Effective
Connectivity
Weightless™ wireless technology offers bidirectional communication enabling unrivaled quality of service (QoS) for large-scale AMI deployments.
Weightless™ was designed for more demanding utility applications that entail HIGH density of end devices, more frequent uplinks/downlinks, and long range. Weightless can operate in sub-GHz licensed as well as sub-GHz unlicensed frequencies (ISM bands).

Meters to Data Concentrator
-
Frequent meter transmission (i.e readings every 5-15 minutes)
-
During power outages, module can manage to send a notice and the last readings
-
Daily registrations: meters can register with the network and send all event data within few hours at high success rate
