Product Summary

The GM47 is a new generation of Sony Ericsson Mobile Communications GSM modules. This document describes the main characteristics and functionality of the GM 47, two dual band products for 900/1800 MHz and 850/1900MHz GSM bands respectively. It is 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. GM47 is 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.

Parametrics

GM47 absolute maximum ratings: (1)Voltage: 3.6V Nominal; (2)Tolerance ±0.2V; (3)Ripple: <100mV @ 200KHz, <20mV @>200KHz; (4)Power consumption: Speech mode < 250 mA (< 2 A peak); (5)Idle mode: 5 mA; (6)Powered off: < 100 μA; (7)RTC accuracy: Max < 37ppm; (8)Typical < 20ppm.

Features

GM47 features: (1)General Packet Radio Service (GPRS). The modules are Class B Terminals, which provides simultaneous activation and attach of GPRS and GSM services. The GM47/GM48 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); (2)Circuit Switched Data (CSD). GM47/GM48 modules are capable of establishing a circuit switch data link at 9.6 kbps; (3)High Speed Circuit Switched Data (HSCSD). GM47 supports HSCSD communication, with one timeslot per frame capacity in the uplink and two timeslots per frame capacity in the downlink (2+1).
