Modern society is an information society. transmission and accessing of information is particularly important with An advantage in a competition. Making the data correct accurate ,efficient, many transmission systems has emerged. A good data system for transmission is very important.
This paper is about design and development for data transmission system based on GSM, which mainly contains the control module, the keyboard of input module, display module, GSM transmission module. System consists of AT89C51, LCD ,four* four Keyboard, TC35i chips and so on. The SCM deal with the data by keyboard, through the GSM system for data transmission. The system's main function is to achieve long-distance transmission of information. When the user input the available information to the system, the system displays the data, then pressing confirm keyboard through the GSM system to send the information to the terminal.
GSM data transceiver system, with low cost, high security, wide regional , high accuracy and high stability of sending and receiving data, can be effectively applied to data transmission.
Keywords: Data transceivers, GSM module, Four* four Keyboard.
