Enfora Enabler II-G Assisted GPS
Modem Integration Guide
12. Integration and Testing
The Enfora Enabler II-G A-GPS 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 Enfora
Enabler II-G A-GPS 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:
GSM0000AN001 - Enabler-G PPP Configuration for Windows 98
GSM0000AN002 - Enabler-G PPP Configuration for Windows 2000
GSM0000AN008 - Enabler-G PPP Configuration for Windows XP
GSM0000AN010 - Enabler-G PPP Configuration for PocketPC 2002
GSM0000AN005 - Enabler-G Automated Network Connection Configuration and Use
12.1. Integrating the Enfora Enabler II-G A-GPS 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),
GPS test equipment or GPS repeater, 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. The GPS tester must have the ability to create a GPS a single channel from a GPS
satellite
Additionally, the serial interfaces and some minimal SIM functionality can be verified by sending
AT commands to the Enfora Enabler II-G A-GPS module.
All of these conditions need to be verified at ambient as well as extreme conditions.
