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® SL7000 electricity meters. This device was designed to be fully compliant with all Itron 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.

This external modem can be mounted on DIN-rail and connected to the meter through an RJ45 cable. The modem can be configured to “push” the read out the data (current consumption, event log, load profile) from the connected meter and send it to the HES periodically via Internet (by using an APN) at the pre-programmed intervals. Data sending can be also triggered by an alarm (e.g. power outage, cover removal event).

The modem can be accessed remotely through the cellular network. The modem can also read or modify certain parameters of the meter remotely via WM-E Term® configuration software.
