ABSTRACT
With the development of information technology, there are various of data transmission way in use, among them the wireless transmission develop much more fast, and it shows the grate vitality and the market prospect. Compare with traditional transmission, the advantage of wireless transmission is outstanding: firstly, wireless transmission is cheap and can reduce a lot of wire to make the environment clear; secondly it fast to build, needless to Revolution, can be used as it installed; thirty wireless transmission easy to adapt, can be used in special environment; lastly it is to expend, it can be used once you connect with other equipment.
Because of all the advantage, the wireless transmission can be widely used in people's study, life and work. It can be seen with the development of wireless technology, wireless transmission will used more wide, more cheaper and more reliable.
My graduation design is by using the micro processor of STC11L04E to control the RF903SE micropower wireless communication module for transmit data from a computer's serial port, then with the RF903SE micropower wireless communication module to send data to another RF903SE micropower wireless communication module, after that the RF903SE send the data to the another micro processor which connect to it, at last, the data successfully to the destination, the another computer. What we done achieve the transparent transmission of data.
