Measure & Record 2G/3G/LTE 4G Cellular Signal Strength, Quality + Other Parameters.
ETM manufacture a range of battery powered hand held tools for monitoring key parameters of any cellular network. Supporting LTE 4G, 3G UMTS, & 2G GPRS (with LPWAN CAT-M1 NB1) versions for all geographic locations.
By measuring parameters like signal strength, base station, cell information, the ideal operator and antenna configuration can be selected.
Information can be logged to ETM’s IoT Cloud Platform for storage or further analysis.
The ETM770 is a handheld battery powered device with LCD screen showing signal strength as well as associated network data. To function correctly the unit requires a suitable SIM to be fitted, and should be connected to the intended antenna(s). Antenna connection is via SMA Jack connector(s), an SMA to FME adaptor is provided. Also included with the kit is a car charger and a USB cable for charging/programming.

Antenna Connectors 4G/3G units come with two antenna connectors, a main antenna and secondary or diversity antenna. If testing with one antenna only, ensure that this antenna is connected to the Main antenna connector. ETM770-4 4G 3G cellular signal strength meter also requires the APN and possibly username/password to be set correctly for the SIM being used.
IP Check In addition to scanning signal strength the unit can be used to ping an IP address (network permitting) to confirm that the connection is suitable for IP traffic.
Configuration Tool A configuration tool is available for the unit and can be used to log signal information if required. In addition via the ETM’s EWO Cloud Platform.
