SMART METERING MODEMS

 

Last Updated on 2026-03-27

ELECTRICITY METERING MODEMS

We have a long history of manufacturing OEM smart meter modems for major meter manufacturers.

Cellular metering modems

Our cellular modems are fully compatible with leading brands such as Itron, Landis+Gyr, Elster/Honeywell, Iskra, EMH, SAPHIR, PME-PMI, Ensor, AECL, Kamstrup and more.

Retrofit Modems

Protect your investment by upgrading modems instead of meters.

Our modems work with any AMR or AMI system, serving as a transparent gateway between the meter and the Head-end System. They use closed Access Point Names (APNs) and Transport Layer Security (TLS) encryption to ensure secure data transmission.

Need a special protocol or port? We offer product customization.

Smart metering has never been so easy!
