Abstract
A wireless communication device stores correspondence information that associates a plurality of operation modes previously selected for communication with a plurality of sender communication devices, with a plurality of identification information items of the sender communication devices. For data transmission to a destination communication device, the wireless communication device selects an operation mode that is previously selected for communication with the destination communication device using the correspondence information.
Claims10
A wireless communication device, comprising:
- at least one antenna;
- means for analyzing receive frame data obtained by demodulating a signal received from a sender communication device through the at least one antenna to obtain identification information of the sender communication device;
- means for measuring a reception condition of the signal received through the at least one antenna for each of a plurality of operation modes of the at least one antenna to generate measuring results for the plurality of operation modes;
- means for selecting one of the plurality of operation modes that is most desirable for communication with the sender communication device based on the measuring results;
- means for storing the selected operation mode in association with the identification information of the sender communication device;
- means for analyzing transmit frame data to be transmitted to a destination communication device to obtain identification information of the destination communication device;
- means for selecting one of the plurality of selected operation modes of the at least one antenna that is stored in association with identification information that matches the identification information of the destination communication device to obtain an operation mode that is most desirable for communication with the destination communication device;
- and
- means for causing the at least one antenna to operate in the operation mode selected for communication with the destination communication device.
