Abstract
A near-field wireless communication circuitincluded in a terminalA can perform switching between a normal mode and a near mode which has a relatively short communicable distance and a relatively high transmission rate as compared with those in the normal mode. Further, a controllerexecutes preliminary processing for starting data transmission and reception in the near mode to/from a terminalB serving as a communication destination between the terminalsA andB by using the near-field wireless communication circuitwhich is set to the normal mode. Further, the controllerdetermines the availability of the data transmission and reception in the near mode to/from the terminalB by using a measured value of communication quality which has a correlation with a communication distance to the terminalB as a measure of the determination. Furthermore, when it is determined that the data transmission and reception in the near node are available, the controllerstarts the data transmission and reception to/from the terminalB by using the near-field wireless communication circuitwhich is set to the near mode, based on a result of the preliminary processing executed in the normal mode in advance.
