GR47/GR48 Technical description
1 Introduction
1.1 Overview
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
1.2 Features
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.

GR47/GR48 Technical description
1.2.2 SMS
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 ne twork, 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.
1.2.3 Voice calls
The GR47/GR48 offers the capability of MO and MT voice calls, as
well as supporting emergency calls. In addition to this multiparty, call
waiting and call deflection features are available. Some of these
features are operator specific.
The module offers normal analogue input/output lines, analogue audio
input/ output lines in differential modes, and digital audio interface,
with the possibility of accessing internal points within t he digital
audio lines. Moreover, the GR47/GR48 have an embedded echo
canceller and noise suppression, which provide high quality audio.
The module supports HR, FR and EFR voice coding, provided that
EFR is available in the network.
1.2.4 Data
The module supports the following data protocols:
• General Packet Radio Service (GPRS). The modules are Class B
Terminals, which provides simultaneous activation and attach of
GPRS and GSM services. The GR47/GR48 modules are GPRS
4+1 devices, which are capable of transmitting in one timeslot per
frame (uplink), and receiving in a maximum of four timeslots per
frame (downlink).
• Circuit Switched Data (CSD). GR47/GR48 modules are capable of
establishing a circuit switch data link at 9.6 kbps.
• High Speed Circuit Switched Data (HSCSD). GR47/GR48 supports
HSCSD communication, with one timeslot per frame capacity in
the uplink and two timeslots per frame capacity in the downlink
(2+1).
