Chapter 1. Introduction
The WM-E1S 4G®is a modem, which is suitable for automated remote reading of electricity
meters remotely, on the 4G LTE-based cellular network.
You can save money by using our modem, because there is no further need of manual readout
of the connected meter systems.
Wireless communication
Over the 4G communication, the device has 2G fallback feature, therefore in case of
outage/inaccessibility of the 4G network it is communicating further on the 2G network.
It supports the multi-operator SIM and the roaming feature, and it is compatible with SIM-Toolkit.
The modem has been designed to provide transparent data link from the meter to the server.
It can be used with push data transmission method, thus the modem can initiate the
communication with the AMR centre periodically at a pre-programmed time interval or triggered
by an alarm (power outage, cover removal, reverse run, etc.)
The communication module is a part of the Smart Metering concept. The device provides a SIM-
card independent- and mobile operator independent solution.
Design and installation
This modem was especially developed for the 3-phase Itrón®SL7000 electricity meters, which
can be connected to the meter by its design and its connection interface. It is installable to the
meter as an external modem –due its DIN-rail adapter (provided to the modem) - which allows
to fix the device.
Operation properties, features
The modem is suitable for reading the meter’s actual and stored consumption values, access the
recorded event log, read the load profile data, and read or modify the parameter set of the meter
- remotely. It can be accessed remotely through the cellular network (by the Telit®module) and
it is able to send data on the Internet by using an APN.
Power source and power outage
The device can be powered from the meter’s mains connection (by general 100V-240V AC
voltage).
