Model:GSM
GSM MOBILE COMMUNICATION TRAINER
Objectives
To understand the basic principles of GSM mobile communication system , in steps of theory, design and practice.
Introduction
Lab mobile communication trainer is a highly flexible GSM modem for easy integration with RS-232 and audio interface. It is equipped with features of circuit switched data, SMS, Voice and GPRS .LAB GSM is a perfect solution to use with SMS gateways, access internet while on the move and corporate communications (GPRS, Data transfer & PC Fax even in remote location). The Mobile communication system is controlled by a microcontroller. Programs for this microcontroller can be written in a variety of languages including Assembly, C The use of Flowcode for mobile communication technology is well supported with an Experimental manual and pre-written high level routines for controlling all parts of the system. This also includes several working programs.
