1. A method of automatically controlling a transmission power of a wireless communication apparatus in order to suppress consumed
transmission power, the method comprising the steps of:
setting the transmission power to a maximum value at a start of transmission;
gradually reducing the transmission power by a predetermined amount, each time when transmission succeeds a predetermined
number of times; and
in the case of a transmission failure at a transmission power which is gradually reduced by the predetermined amount, determining
a power which is higher by the predetermined amount than the transmission power, as an optimum value.
