How does an In-meter Gateway improve smart meter communication?

An In-meter Gateway acts as a gateway within the RF mesh network. It collects data from nearby smart meters and securely sends it to the Head-End System (HES) using the cellular network. Its communication performance is similar to a standalone gateway, making deployment simpler and reducing the need for separate gateway installations.

Can utilities install an In-meter Gateway without replacing existing smart meters?

Yes. Utilities can insert the hot-swappable module into compatible commissioned smart meters without replacing the meter. The installation process takes less time and causes minimal disruption to consumers, making it easier to strengthen communication networks in existing AMI deployments.

How does Kimbal’s In-meter Gateway ImGATI improve RF mesh coverage?
