In order for the communication via the mobile network to function satisfactorily it is required that the signal quality at the site is adequate and stable. With ETM770 you only need a SIM card to be able to view the signal strength of all available operators. You can also do test broadcasts to test the GPRS/UMTS/LTE connection. ETM770 is an ideal tool for field installations in order to verify and optimize the signal quality and secure the wireless communication between applications and systems.
