<p>PROBLEM TO BE SOLVED: To provide radio communication equipment on which two radio communication means are mounted, where a modulation/demodulation system or a path for up-conversion and down-conversion is selected between the radio communication means. SOLUTION: A radio communication means 123 (124) incorporates changeover devices 104, 105 (115, 116). The radio communication equipment uses the changeover device to select a path, depending on the transmission/reception system of the radio communication means 123, 124 and omits modulation/demodulation and base-band processing when both the means adopt the same transmission/ reception system for the transmission and reception. Even when the radio communication means 123, 124 use a different transmission/reception system, transmission/reception is conducted by the use of demodulators 103, 114, modulators 102, 113 and base-band processing sections 101, 112, in matching with the modulation demodulation system.</p> |
