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).

Uplink
Meters to Data Concentrator

  1. Frequent meter transmission (i.e readings every 5-15 minutes)

  2. During power outages, module can manage to send a notice and the last readings

  3. Daily registrations: meters can register with the network and send all event data within few hours at high success rate
