Abstract:
1. A wireless communication method performed by a wireless communication device having an antenna unit comprising at least one of (a) a plurality of antennas configured to operate according to a plurality of antenna operation modes each indicating a specified antenna amongst the plurality of antennas that is to be used for communication and (b) an antenna configured to operate according to a plurality of directional patterns and according to a plurality of antenna operation modes each indicating a specified directional pattern amongst the plurality of directional patterns that is to be used for communication, the method comprising: analyzing receive frame data obtained by demodulating a signal received from a sender communication device through the antenna unit, and extracting an address of the sender communication device from the receive frame data when a destination address included in the receive frame data is addressed to another device other than the wireless communication device; measuring a reception condition of the signal received through the antenna unit for each of a plurality of sender antenna operation modes of the antenna unit to generate measuring results for the plurality of sender antenna operation modes; selecting, based on the measuring results reflecting reception conditions one of the plurality of sender antenna operation modes for communication with the sender communication device; storing an identification of the selected sender antenna operation mode in association with the address of the sender communication device as a destination address when the destination address included in the receive frame data is addressed to said another device other than the wireless communication device; analyzing transmit frame data to be transmitted to a destination communication device to obtain an identification of the destination communication device; selecting a destination antenna operation mode based on a sender antenna operation mode that is stored in association with an associated destination address an which matches the identification of the destination communication device; causing the antenna unit to operate in the selected destination antenna operation mode to communicate with the destination communication device; counting a total number of times a specific sender antenna operation mode is selected for a specific sender communication device to generate a number of selections of the specific sender antenna operation mode with respect to the specific sender communication device; and storing the number of selections in association with an identification of the respective specific sender antenna operation mode and an identification of the respective specific sender communication device, wherein the destination antenna operation mode is selected based on which sender antenna operation mode has a greatest associated number of selections stored in association with an identification of a sender communication device which matches the identification of the destination communication device.
