| Abstract |
In the video data processing utilizing wireless communication is a situation with a large amount of data transmission, communication costs excessive, communication distance limit, communication equipment construction and management costs increase disbursed. In this study, the broadcaster developed a server system for the station system for the radio modem, repeater and idle channel frequency connection and data management for the terminal equipment for data collection using the TVWS (Television White Space) frequency band that is not used by the broadcaster. This technology is free of data communication costs, medium and long distance communication is possible, except for maintenance costs compared to conventional wireless communication equipment, and it is possible to send images and texts through the data speed of 20Mbps level. |
