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 from GSM / UMTS 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.  

Protect your investment! No need to change the currently used meters.

Our company develops cellular snap-in modems that work smoothly and are fully compatible with the different models of Landis+Gyr electricity meters. These devices were designed to fit under the terminal cover of the meter and are compliant with all Landis+Gyr 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.

 

Benefits

  • Protect your investment! No need to change the currently used meters.
  • Snap-in modems (drop & plug, easy installation)
  • 4G with 2G or 3G/2G fallback (backward compatibility with current systems)
  • Option for migrating to LTE Cat.M / Cat.NB
  • Long-term solution: the 4G LTE will be used for 10 years or more
  • Self-recovery: the watchdog makes sure the device is able to self recover from faults
