WIRELESS COMMUNICATION UNIT CONNECTED DETACHABLY WITH EXTERNAL UNIT

摘要

A wireless communication unit comprises wireless communication means, a microcontroller and a memory unit, and it is detachably connected with an external unit such as a personal computer. The wireless communication means has an identification number for wireless communication and communicates with external devices. The microcontroller, which is means for controlling the wireless communication means and the memory unit, allows an external unit to communicate with another external unit through the wireless communication means when the wireless communication unit is connected with the external unit. The microcontroller allows an external unit to use the memory unit as a file system of a predetermined operating system when the wireless communication unit is connected with the external unit. The microcontroller allows the wireless communication means to communicate using the memory unit according to an instruction from an external unit or from the microcontroller.
