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 within their routers! 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 3-phase Itron® electricity meters. This device was designed to be fully compliant with all Itron standards.

The modem have RS232 and RS485 connection capabilities, and provides a transparent data link to the HES, through the 4G LTE / 2G / 3G / LTE Cat.M or Narrow Band wireless network.

Our cellular modems represent a future-proof migration solution to the LTE network with the same functionality, on higher data speed.

Suitable for remote meter readout of electricity meters, meter data download and configuration on the provider’s request by schedules or on-demand.

It is possible to use this device as a universal external modem – as it you can connect it to almost any meter via RS232 and RS485.

Configuration and firmware updates can be done remotely, minimizing the need for costly site visits.
