Abstract:
1. A communication apparatus comprising: a first communication unit which wirelessly communicates with a first device using a channel in a frequency band; a determination unit which determines a number of times by which the first communication unit transmits data to the first device before transmitting the data; a communication controller which controls the first communication unit to transmit the data to the first device by the number of times determined by the determination unit; and a second communication unit which wirelessly communicates with a second device using a channel in the frequency band, wherein the determination unit comprises a communication detecting unit which detects whether the second communication unit communicates with the second device, and wherein the determination unit determines that the number is a first number when the detecting unit detects that the second communication unit communicates with the second device, and the determination unit determines that the number is a second number smaller than the first number when the detecting unit detects that the second communication unit does not communicate with the second device.
