发明名称 Communication apparatus and communication method
摘要 A communication apparatus which communicates data with plural other communication apparatuses by performing wireless communication includes: plural antennas; a communication level obtainment unit which obtains communication levels for the antennas obtained when the communication apparatus performed the wireless communication with the other communication apparatuses; a count unit which counts, for each of the antennas, the number of established communications that is the number of one or more of the other communication apparatuses which successfully established communication through the antenna; an antenna selection unit which selects, when the total number of antennas whose numbers of established communications are greatest is more than one, one of the antennas corresponding to a communication level that is highest among communication levels of plural antennas of the other communication apparatus corresponding to the lowest communication level; and a transmission unit which broadcasts predetermined data to the other communication apparatuses through the selected antenna.

主权项 1. A communication apparatus which communicates data with a plurality of other communication apparatuses by performing wireless communication, the communication apparatus comprising: a plurality of antennas which transmit and receive a radio wave for the wireless communication; a communication level obtainment unit configured to obtain communication levels obtained when the communication apparatus performed the wireless communication with the other communication apparatuses, the communication levels being obtained for a plurality of pairs each including one of the antennas and one of the other communication apparatuses; a count unit configured to count, for each of the antennas, the number of established communications that is the number of one or more of the other communication apparatuses which successfully established communication through the antenna; a determination unit configured to determine whether or not a total number of antennas whose numbers of established communications counted by the count unit are greatest is more than one; an antenna selection unit configured to, when it is determined by the determination unit that the total number of antennas whose numbers of established communications are greatest is more than one, identify one of the other communication apparatuses corresponding to a lowest communication level among the communication levels of the pairs obtained by the communication level obtainment unit, and select, as an antenna for use in broadcasting, one of the antennas corresponding to communication levels higher than the lowest communication level among communication levels of the identified other communication apparatus through the antennas; and a transmission unit configured to broadcast predetermined data to the other communication apparatuses through the antenna selected by the antenna selection unit.
