employment prospects of radio technology major. The characteristic of radio technology major is wireless data transmission, especially the real-time transmission of video data, which has always been the focus of current research, involving important technologies such as data acquisition, signal and information processing, communication and control. It covers a wide range, including almost all aspects of the electronic information field, and develops rapidly. Every branch field IT contains has great development potential. This field is different from IT, and it is actually developing steadily by technological progress. With the development of wireless communication technology and optical communication technology, the design and optimization of radio frequency technology, microwave and optoelectronic devices, optical fiber communication system and optical fiber sensing system have become hot technologies.
