摘要： A wireless device is capable of transmitting a plurality of frames to the same destination in parallel using a plurality of frequency channels. The wireless device includes: a first transmitter 21 which transmits a frame using a first frequency channel; a second transmitter 22 which transmits a frame using the second frequency channel; and a controller 43 which provides a frame stored in a buffer to the first transmitter if the first frequency channel is determined idle before the second frequency channel is determined idle. The controller 43 provides a frame stored in the buffer to the second transmitter if it is determined that a state that the second frequency channel is idle has continued for a second time before if it is determined that a state that the first frequency channel is idle has continued for a first time. The wireless device configured as above can prevent throughput reduction and suppress the occurrence of a delay beyond an allowable range.
