An arrival angle estimation system comprises a transmitting device and a receiving device, the arrival angle estimation system estimating an arrival angle at which frames transmitted by radio from the transmitting device arrive at the receiving device, wherein the transmitting device includes a directional antenna having directivity toward the front of the transmitting device; the receiving device includes two directional antennas each arranged so that its directivity is tilted at ±¸ degrees with respect to the front of the receiving device; and frames transmitted from the transmitting device are received by using the directional antennas alternately, and received signal strengths of the frames at the respective receiving directional antennas are compared with each other to estimate the arrival angle. |
