GSM/GPRS Modules

Introduction GSM
GSM stands for Global System for Mobile Communications. It refers to the method that is responsible communication between two GSM devices like Mobile/ Cell Phone. We can talk with cell phone, send and receive SMS, MMS, Browse internet. There is only one technology works behind this that is GPRS. Through GPRS – General Through Packet Service, All this communication happens. Here Are following devices are available in the market that can be used to build custom hardware applications using 8051 Microcontrollers. Interfacing GPS Modules with 89C51 microcontroller is so simple, you can use even 89C52 Micocontrollers to interface and create applications. GSM Modules can be connected through USB or RS232 of 89S52, 89S52 Microcontroller. These are also the variant of 8051 Microcontrollers. GSM Module with RS232 Serial Port can be connected directed with 89C51 Microcontrollers RS232 Section.
