UPGRADE THE MODEMS NOT THE SMART METERS!

All around the world mobile operators are shutting down 2G/3G networks in order to give way to 5G. Companies that operate smart meters with 2G/3G connectivity must plan the migration to the latest 4G LTE network which is well-positioned to dominate smart metering communication technologies in the upcoming years. The migration to LTE has many advantages, for example, a shorter readout time due to the high-speed network with low latency.

Utilities have two options for migration: replace the meters or upgrade the modems! The 1st option comes with a high CAPEX, while the 2nd option is a future-proof solution that reduces TCO.

Our company develops cellular modems that work smoothly and are fully compatible with the different models of Honeywell AS type electricity meters.

These devices were designed to fit under the terminal cover of the meter and are compliant with all Honeywell standards.

Our cellular modems represent a future-proof migration solution to the LTE network with the same functionality, on higher data speed. Configuration and firmware updates can be done remotely, minimizing the need for costly site visits.

The product case was designed to fit under the terminal cover of the meter. As part of an AMR/AMI solution, the modem provides a stable, transparent “push” or “pull” LTE data connection to the HES.

The modem reads actual and stored consumption data, recorded event log, and load profile data by “push” or “pull” data transfer method.

The device is fully configurable by our WM-E Term^® software and remotely manageable with the Device Manager^® software (order option).
