The Novatel Wireless M2M Enabler IIIG module has been designed to minimize the amount of
time required for integration and testing the application. By being fully certified by the
appropriate bodies, the Novatel Wireless M2M Enabler IIIG module provides seamless
integration into the GSM network.
The integration issues for the application can be narrowed to the utilization of the AT
commands and the use of the GSM functionality. Coverage and signal quality may be
evaluated by using the RSSI commands. Additional network information can be determined
by using AT commands.
Integration of the GPRS Packet capabilities is more complicated than using AT command
sequences to initiate the connection and begin transferring data. The following Application
Notes should be used to integrate the GPRS packet capabilities:
l
GSM0000AN001 - Enabler-G PPP Configuration for Windows 98
l
GSM0000AN002 - Enabler-G PPP Configuration for Windows 2000
l
GSM0000AN008 - Enabler-G PPP Configuration for Windows XP
l
GSM0000AN010 - Enabler-G PPP Configuration for PocketPC 2002

GSM0000AN005 - Enabler-G Automated Network Connection Configuration and Use
Integrating The Novatel Wireless M2M Enabler IIIG
Module
Note: Generally, all interfaces that are externally available to the end user need to be ESD-
conditioned and terminated in some way. Many of these interfaces should not be connected
with power applied.
At the highest level, this is done using some type of GSM test equipment (such as, Racal
6103E), a computer, and a serial interface tester. The GSM test equipment must be able to
simulate a GSM call and measure the key parameters related to the module.
Additionally, the serial interfaces and some minimal SIM functionality can be verified by
sending AT commands to the Novatel Wireless M2M Enabler IIIG module.
All of these conditions need to be verified at ambient as well as extreme conditions.
As part of integration, each of the following interfaces must be verified:
Information Recommendations
SIM
The maximum line length of the SIM interface is 25.4 cm (10
inches).
The Novatel Wireless M2M Ena-
bler IIIG module takes care of
the signal conditioning
As a minimum, an external
application with a remote SIM
will require a standard SIM car-
rier.
