摘要：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.
