TRANSMISSION METHOD, TRANSMISSION SUCCESS/FAILURE DETERMINATION METHOD, TRANSMITTER, AND TRANSMITTING/RECEIVING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a transmission method, a transmission success/failure determination method, a transmitter, and a transmitting/receiving system which can reduce a time until a data communication with a receiving device becomes possible, without using useless power when a connection by the last transmission power value is impossible upon reconnection.

SOLUTION: A transmitter is provided with a transmission success/failure detection means 211 detecting a success/failure of a transmission, a transmission power value selecting table 24 in which a plurality of power values are divided in groups per a predetermined width according to magnitudes in stages, a transmission power value setting means 25 setting a minimum power value among power values which belong to a group of a power value larger by one stage than a group to which a transmission power value which has failed belongs as a subsequent transmission power value by referring to the transmission power value selecting table 24 when the transmission has failed, and determining a transmission power value which has succeeded as a transmission power value for communicating with the receiving device as it is when the transmission has succeeded, and a transmission means 26 transmitting with the transmission power value set by the transmission power value setting means 25.
