GR47/GR48 Technical description
1 Introduction
1.1Overview
The GR47/GR48 belong to a new generation of Sony Ericsson Mobile Communications GSM modules. This document describes the main characteristics and functionality of the GR47/48, two dual band products for 900/1800 MHz and 850/1900 MHz GSM bands respectively.
They are intended to be used in both machine-to-machine applications and man-to-machine applications. The module serves its purpose when there is a need for sending and receiving data (by SMS, CSD, HSCSD, or GPRS), as well as making voice calls over the GSM network.
GR47/GR48 are business-to-business products. It is intended to be sold to manufacturers, system integrators, applications developersdeveloping solutions with wireless communication. The module is intended to be integrated by the system integrator within an application. The module and the external application will form a system for wireless communication.
A typical system is one where a micro controller in an external application communicates with the module over its serial interface. The micro controller will control the module, via the supported set of AT commands. It is assumed that the system integrators have a high technical knowledge and the ability to integrate the module into a system. For the GR47/GR48 modules some interesting applications are the following:
∙Fleet and Asset Management
∙Vending Machines
∙Security and Alarm
∙Other telemetry applications

GR47/GR48 Technical description
1.2Features
The module performs a set of telecom services (TS) according to GSM standard phase 2+, ETSI and ITU-T. The functions of the module are implemented by issuing AT commands over the serial interface. Supported AT commands are listed in section 5, these are defined further in GSM 7.05/7.07 and the GR47/GR48 integrator’s manual.

The module supports the following SMS services:
∙Sending: MO, both PDU and Text mode supported.
∙Receiving: MT, both PDU and Text mode supported.
∙CBM is a service, in which a message is sent to all subscribers located in one or more specific cell(s) in the GSM network, for example, cell location information.
∙SMS STATUS REPORT according to GSM 03.40.
The maximum length of an SMS message is 160 characters when using 7-bit encoding. For 8-bit data, the maximum length is 140 characters.
The module supports upto 6 concatenated messages to extend this function.
