Abstract

Provided is a wireless transmitter-receiver capable of suppressing undesirable power consumption and elongating the continuous operation time by operation of a user with the intention of controlling transmission power and also suitable to secure the “symmetry of communication”.

The wireless transmitter-receiver decreases the upper limit value of transmission power by an operation of an operation means 114 and decreases the reception sensitivity in accordance with the decreased upper limit value of transmission power. Thereby, a user can determine the upper limit value of transmission power of the wireless transmitter-receiver and manage the transmission power to suppress power consumption and elongate a continuous operation time. Moreover, the wireless transmitter-receiver can eliminate the influence of radio frequency electromagnetic field on a human body. Furthermore, the degree of imbalance in the “symmetry of communication” can be minimized.
