2. GENERAL PRODUCT DESCRIPTION
Overview
The ME910G1 module is a CATM / NBIoT communication product which allows integrators
to plan on availability for even the longest lifecycle applications, highly recommended for
new designs specified for coverage worldwide.
The product is fully voice capable, the digital audio interfaces make it suitable for
applications such as voice enabled alarm panels, mHealth patient monitors and specialty
phones such as those for the elderly or sensory-impaired.
The ME910G1 operates with 1.8 V GPIOs, minimizing power consumption and making it
even more ideally suited for battery powered and wearable device applications.

Mechanical Specifications
2.7.1. Dimensions
The overall dimensions of ME910G1-W1 and ME910G1-WW are:
•Length: 28.2 mm
•Width: 28.2 mm
•Thickness: 2.4 mm
2.7.2. Weight
This information will be available in a next document revision.
Temperature Range
Note
Operating Temperature
Range
–20°C to +55°C
The module is fully functional(*)
within this 3GPP temperature
range and meets 3GPP
specifications.
Extended Temperature
Range
–40°C to +85°C
The module is fully functional (*)
within this temperature range.
The RF performance may
deviate from 3GPP
requirements in this extended
range. For example: receiver
sensitivity or maximum output
power may deviate by a few dB
due to limitations of physics like
higher thermal noise floor at
high temperature.
Storage Temperature
Range
–40°C to +85°C
-
(*) Functional: if applicable, the module is able to make and receive voice calls, data calls,
send and receive SMS and data traffic.
