PROBLEM TO BE SOLVED: To improve power consumption reduction performance.SOLUTION: A radio communication device selects a high-speed first communication scheme or a second communication scheme slower than the first communication scheme depending on the state of a line network. If the radio communication device selects the first communication scheme, it controls the power source voltage of an amplification unit, which amplifies a transmission signal transmitted by radio communication to a prescribed power level, by a first control scheme. If the radio communication device selects the second communication scheme, it controls the power source voltage of the amplification unit by a second control scheme different from the first control scheme. |
