The proposed project is intended to design an access control system using GSM technology. GSM (Global System for Mobile communication) is a digital mobile telephony system that uses a variation of Time Division Multiple Accesses (TDMA) and most widely uses the three digital wireless telephony technologies i.e., TDMA, CDMA & FDMA. The present project is an innovative idea for providing security by restricting the access of certain areas to certain people only. In this case of security, the opening & closing of the gate of the restricted areas is done through SMS. A GSM modem is used for this purpose. It allows only authenticated SIM cards or number for the access purpose rejecting all other unauthenticated SIM card users. When an ‘OPEN ’SMS is sent, the gate opens up and then closes automatically.
