Differences in transmission delays in multiple wireless lines can be suppressed with the help of a wireless communication device, a wireless communications system, and a wireless Communication method.
Provided are a wireless communication device, a wireless communication system, and a wireless communication method, with which differences in transmission delays in multiple wireless lines can be suppressed. The wireless communication device (1) has a division means (12) and a transmission means (14). The transmission means (14) transmits radio waves via multiple wireless lines. The division means (12) generates multiple fragments by dividing data into sizes corresponding to the respective transmission capacities of the multiple wireless lines. Furthermore, the transmission means (14) transmits each of the multiple fragments to another wireless communication device via a wireless line having a transmission capacity corresponding to the size of the respective fragment.
