2GENERAL PRODUCT DESCRIPTION
2.1 Overview
The Telit ME310G1 module is a CATM / NBIoT communication module that allows
integrators to plan availability for lifecycle applications.
The Telit ME310G1-WWV module is fully voice capable with a Digital Voice Interface (DVI).
It is suitable for applications such as voice-enabled alarm panels, mHealth patient
monitors, and special devices used by elderly or disabled.
The Telit ME310G1 module operates with 1.8 V GPIOs, minimizing power consumption.
This makes it suitable for battery-powered and wearable devices.

firmware version and firmware configuration used.
Note: “B86” is not a 3GPP band, it means the following:
UL range: 787-788 MHz, DL range: 757-758 MHz that is available only
in module where AT#BNDOPTIONS command contains the string
B86. that is AT#BNDOPTIONS?
#BNDOPTIONS: 1,2,3,4,5,8,12,13,18,19,20,25,26,27,28,66,71,85,86.
Note: “B8_39d” is not a 3GPP band, it means the following:
U.S. FCC 900MHz that employs 39MHz duplexing
UL range: 897.5-900.5MHz, DL range: 936.5-939.5
It is available only in the module where AT#BNDOPTIONS command
contains the string B8_39d. that is AT#BNDOPTIONS?
#BNDOPTIONS: 1,2,3,4,5,8,12,13,18,19,20,25,26,27,28,66,71,85,
