Claim Text:
1. A wireless communication apparatus, comprising: a determination unit configured to determine whether or not a signal degradation degree of a wireless communication is higher than a threshold value, the signal degradation degree indicating a degradation degree of a signal quality; a first setting unit configured to set first parameters if communicating with a communication partner, the first parameters relating to a first data rate and a first communication robustness; a timer configured to measure a time until an elapse of a first interval upon receiving one of an instruction signal from an upper layer and a close-proximity detection signal, the close-proximity detection signal indicating that the communication partner falls within a distance; a second setting unit configured to set second parameters if the signal degradation degree is higher than the threshold value and if the time exceeds the first interval, the second parameters relating to a second data rate and a second communication robustness, the second data rate being lower than the first data rate, the second communication robustness being higher than the first communication robustness; and a wireless unit configured to communicate with the communication partner using one of the first parameters and the second parameters, wherein the timer measures a second interval upon detecting the close-proximity detection signal, and measures a third interval upon detecting the instruction signal, if only the close-proximity detection signal is received, the timer sets the second interval as the first interval and measures the time, if only the instruction signal is received, the timer sets the third interval as the first interval and measures the time if both the close-proximity detection signal and the instruction signal are received, the timer sets the third interval as the first interval and measures the time, and the timer sets the third interval greater than the second interval.
