COMMUNICATION APPARATUS AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To prevent sudden interference on other communication station (communication unit). SOLUTION: A signal is transmitted at a 1st communication speed (β[kbps]) for a prescribed start time, and the signal is transmitted at a 2nd communication speed (ε [kbps]) higher than the 1st communication speed. Or a transmission time ratio (a ratio of a transmission time to a time) may be switched in place of switching the communication speed.
