Nokia 12 GSM Module Hardware Integration PDF Manual

This document provides instructions for the Nokia 12 GSM module (hereafter Nokia 12 module) hardware integration. The document is intended to help the system integrator to integrate the Nokia 12 module into a remote end hardware application and to gain the necessary type approvals. The document describes the mechanical, electrical and radio frequency (RF) integration as well as antenna installation.

INTRODUCTION
The Nokia 12 module has been designed for M2M (machine-to-machine) applications and other wireless solutions. There are two versions of the Nokia 12 module:
• RX-2 dual-band GSM device supporting EDGE, GPRS, HSCSD, CSD, and SMS in EGSM 900/GSM 1800 MHz bands
• RX-9 dual band GSM device supporting EDGE, GPRS, CSD, SMS in GSM 850/GSM 1900 MHZ bands.

The Nokia 12 module can be used in several applications due to its three different operating modes. Simple I/O applications can be easily implemented by using the Nokia 12 module in the User control mode that offers message personalising, secure messaging, and timing functionality for SMS controlled I/O applications. In the AT command mode, the Nokia 12 module can be used as a GSM modem. In modem use, all supported bearers are available. The Nokia 12 module is Nokia M2M Platform compatible. In the M2M system mode, the Nokia 12 module communicates with the server application through the Nokia M2M Gateway, and all the compatible features of the Nokia 12 module are available for developing a wide range of M2M applications. In addition to the different operating modes, the Nokia 12 module has an integrated TCP/IP stack which enables direct GPRS or GSM data connection between a remote end application and a server application. Due to the integrated TCP/IP stack, the HTTP and Socket APIs of the Nokia 12 are available for application development.

In addition to the bearers and operating modes listed above, the Nokia 12 supports several Java™ APIs, location service for external GPS module
integration, reliability features like AutoPIN, GSM encryption and security codes, reset mechanism and Nokia M2M Platform authentication. Java
technology support enables upgrading the application software over-the-air, and smart messaging makes the installation flexible. GSM phase 2+
supplementary services enable voice application development.

MECHANICAL INTEGRATION
The Nokia 12 module contains two holes for mounting screws. The screws can be used in mounting, but are not compulsory. The Nokia 12 module has been tested according to the automotive standard DIN 72300-3 (although not in various temperatures), and it can be integrated into various applications without the screws.

M2M SYSTEM CONNECTOR
All signals are routed through the M2M System Connector, except the antenna, which is routed through the miniature microax (MMCX) RF connector. The M2M System Connector is a 60-pin (2 rows, 30 pins per row), 1.27 mm/0.05 inch pitch pin header connector. It has a frame that helps in the physical integration and also holds the Nokia 12 module firmly in position. The possible mating connector is described in Table 3.
