The present invention addresses the problem of an increase in transmission delay when a communication is performed using a plurality of wireless transmission devices having different wireless transfer delays if a plurality of wireless lines are regarded as a single wireless line. A wireless communication device according to the present invention includes: a dividing means for dividing a data signal string into a plurality of divided signal strings; and an allocation means for allocating the divided signal strings to at least one of a plurality of wireless transmission means having different wireless transfer delays on the basis of a transmission delay due to the intermediation of the wireless transmission means.
