A wireless communication device including two wireless transceivers and a controller is provided. The first and second wireless transceivers provide a first connection and a second connection for wireless transmission and reception using a first wireless technology and a second wireless technology, respectively. The controller determines a first period of time from reception of a request for transmitting a packet transmission of a data flow by the first wireless transceiver to a start of the packet transmission over the first connection via the first wireless transceiver, or a second period of time from reception of the request for transmitting the packet of the data flow by the first wireless transceiver to reception of the packet by a router, and activates a multipath communication protocol, based on the first or second period of time, for transmitting subsequent packets of the data flow over both the first and second connections.
