Title of Dissertation/Thesis：Research and Realization of Wireless Communication Technology
Abstract:
In recent years, wireless communication technology has experienced a rapid development. We can see high-speed Radio frequency chip, Bluetooth and WIFI modules in the market，they all have wide communication band-width, and still robust stability, so they can be used to transfer video, audio and text. People integrate the technology of data processing and wireless transmission, which can be used in the fields of industry control, sensor, detecting, data collection, distance conference and so on. Due to above reason, this thesis developed a wireless video transmission system, which consists of ARM11 and 8051 evaluation board, WIFI and RF modules, the host system collects the video from Personal Computer or other ROM, encodes each frame of the video with H.264 format, then sends it into the buffer of WIFI to be transmitted, the guest receives the data from it’s WIFI, then sends it into ARM to decode and displays the video in guest’s LCD screen. What is more, an 8051 evaluation board communicates with the ARM board through nRF24L01 chip, which can control the beginning, pausing and stopping of the system. More, this system can also play a role in a testing platform of RF chips, we can measure the index of transmitting rate and valid transmitting distance with the system. Visual C++6.0 is used to program USB and video under Windows operation system. Keilu Vision 3 is used to program 80C51 and CY7C68013A. Vim is used to develop the driver of kernel and ARM.
