Cellular modem for Landis+Gyr E350, E450 (ZMD310, ZMD410 type) and E650 type electricity meters – for 4G LTE Cat.1 / 2G / 3G, Cat.M and Cat.NB networks
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 electricity meters.
This cellular modem has been specifically designed for use with specific Landis+Gyr® electricity meters. It can be ordered with two types of housing, one for the E350 and E450 meters and another one for the meter E650.
The modem has RS232 (RJ45) or RS485 (RJ45) connection capabilities, and provides a transparent data link to the HES, through the 2G / 4G LTE / Cat.M and Narrow Band wireless network.
Our modem forms part of the AMI (Advanced Metering Infrastructure) of the utility company.
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/RS485.
