GSM or Global System for Mobile Communication is a Wireless Communication standard for mobile telephone systems. Difference between a Module, MODEM and Mobile (System).to name some.īefore going in to the details about the GSM/GPRS Module, we will first see a few basic things like GSM, GPRS, MODEM, Module and System.Īlso read HOW TO INTERFACE GSM/GPRS MODULE WITH 8051? Such wireless connectivity of microcontroller opens up to wide range of applications like Home Automation, Home Security Systems, Disaster Management, Medical Assistance, Vehicle Tracking, Online Banking, E – Commerce etc. GSM / GPRS Modules allow microcontrollers to have a wireless communication with other devices and instruments. With the help of this communication interface, we can connect the GSM GPRS Module on the GSM GPRS MODEM with an external computer (or a microcontroller). Here, GSM stands for Global System for Mobile Communication and GPRS stands for General Packet Radio Service.Ī GSM GPRS MODEM comprises of a GSM GPRS Module along with some other components like communication interface (like Serial Communication – RS-232), power supply and some indicators. A GSM GPRS Module is used to enable communication between a microcontroller (or a microprocessor) and the GSM / GPSR Network. GSM GPRS Modules are one of the commonly used communication modules in embedded systems.
