<p>PROBLEM TO BE SOLVED: To provide the radio system provided with a radio medium that is made small and has provision for various radio modes. SOLUTION: The radio system consists of a radio medium 11 and an information terminal 12 to/from which the radio medium is attached/detached. The radio medium consists of a memory 24 that stores various radio modes, a frequency conversion module 23 that has a frequency conversion and transmission/ reception function and an enclosure that contains the memory and the frequency conversion module and has a connection section. The terminal 12 consists of a connection section to/from which the radio medium 11 is attached/detached mechanically and electrically, a conversion module 31 that applies digital/analog conversion to transmission reception signals, and a signal processing module 32 that processes a digital signal corresponding to the transmission reception signal according to a radio mode read from the memory.</p> |
