ABSTRACT:
An information processing apparatus executes processing based on received information conforming to IEEE 802.11n, and includes: an incident angle measuring unit acquiring a received signal and measuring an incident angle of the received signal's radio wave; a reliability estimating unit estimating reliability of a measurement result of the incident angle, by analyzing a state of occurrence of fading using a relationship between frequency and signal intensity of the received signal; and a processing unit executing or controlling processing utilizing the measurement result of the incident angle. The processing unit executes or controls the processing utilizing the measurement result of the incident angle if the estimating unit judges that the reliability of the measurement result of the incident angle is high, and prohibits the processing utilizing the measurement result of the incident angle if the estimating unit judges that the reliability of the measurement result of the incident angle is low.
