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 different models of SAPHIR electricity meters. This device was designed to be fully compliant with the SAPHIR standard. 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.

This external modem can be mounted on a DIN-rail and connected to the meter through an RJ45 cable. It can be configured to “push” the data it reads from the meter to the HES periodically at pre-programmed intervals or triggered by an alarm/event (for example, power outage, cover removal, reverse run etc.).

The modem reads actual and stored consumption data, recorded event log, load profile data, and can be used to read or modify certain parameters of the meter remotely. The device can be powered from the meter’s mains connection of the 57/100V AC power network (phase voltage) or 230/400V AC power network (line voltage).

It can be accessed remotely through the cellular network and it can send data on the Internet by using an APN.

The modem is fully configurable by our WM-E Term® software.
