Abstract:
1. A wireless communication device comprising: a near field wireless communication circuit being capable of switching between a first communication mode to perform OFDM (Orthogonal Frequency Division Multiplexing) and a second communication mode with a relatively short communicable distance as compared with that in the first communication mode and to perform spread spectrum; and a control unit being capable of controlling the switching between the first and second communication modes, wherein the control unit is adapted to: execute, with a destination device through the near field wireless communication circuit that is set to the first communication mode, preliminary processing needed for initiating data transfer in the second communication mode with the destination device; determine availability of the data transfer in the second communication mode with the destination device by using a measured value of communication quality related to a communication distance to the destination device as a measure of the determination; and initiate, when it is determined that the data transfer is available, the data transfer by using the near field wireless communication circuit that is set to the second communication mode, based on a result of the preliminary processing.
