Abstract—
In this technical paper explains how a reliable and an authentic wireless communication could be easily developed between a mobile phone and microcontroller using GSM (Global System for Mobile Communication) MODEM (Modulator-Demodulator). This technical paper explains GSM based e-notice board which can be widely used for multitude of applications including educational sector, traffic control, banks, public advertisements, stoke exchanges etc. Moreover we can also learn as well as modify some of the common applications of GSM MODEM as per the requirements and needs of the user. Here we will learn the hardware behind the picture. In addition to this I will tell you how to upgrade the software resulting low NRE (Non-Recurring Engineering) cost as well as low time-to-market. This technical paper plays a vital role in the state-of-the-art scenario where market window is relentlessly shrinking and really need pocket-friendly and authentic products.
GSM - a digital mobile telephony system, which is globally accessed by more than 212 countries and territories. Global system for mobile communication is completely optimized for full duplex voice telephony. Initially developed for the replacement of first generation (1G) technology, now GSM is available with lots of salient features with the constant up gradation of third generation (3G) technology.
And now with the alliance of microcontroller, GSM MODEM could be further tailor-made for some of very innovative applications including GSM based DC motor controller, GSM based home security system, GSM based robot control, GSM based voting machine control, GSM based stepper motor controller etc.
MAIN FUNCTION OF GSM BASED E-NOTICE BOARD
• Sending message from any of the remote area to the distant located e-notice board using GSM mobile.
• For sending the text message from remote area we need to interface the mobile phone with GSM Modem.
• For developing some of GSM based applications we need to have some commons peripherals including GSM MODEM, SIM, microcontroller, LCD (Liquid crystal display), power supply and also some connecting wires.
