literature survey of gsm based electronic notice board

—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 ModulatorDemodulator). This technical paper explains GSM based enotice 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-tomarket. This technical paper plays a vital role in the state-of-theart
scenario where market window is relentlessly shrinking and really need pocket-friendly and authentic products.
