A technology which includes the functioning of a wireless LAN and Bluetooth in a Linux board was established. Since it can be utilized for inclusion in the existing product, as well, the inclusive technology of the wireless-data-communications obtained in this research and development will also be effective from the viewpoint that it will give added value to products. In order to utilize the functioning of a wireless-data-communications (wireless LAN and Bluetooth), an inclusion Linux board was adopted. A wireless-data-communications function is incorporated on an open source Linux, and simultaneously with a power supply injection, it becomes possible to start a kernel starting, automatic login, and application program. It enables interface with loading devices to give flexibility to programming which operates the GPIO port on a Linux board. It was applicable as a form of distant place monitor loading technology for use with simple types of camera equipment.
