Abstract
A wireless communication apparatus includes a random number range holding unit configured to hold a random number range, a random time setting unit configured to set a random time based on the random number range, a random time counting unit configured to count the random time starting from a particular time only when the radio communication channel is not used, a transmitting unit configured to transmit data via the radio communication channel when counting of the random time was completed, a time counting unit configured to count a particular time, and a random number range control unit configured to control the random number range such that when data transmitted by the transmitting unit over the radio communication channel collides with another data, the random number range is expanded, while when the particular time has been counted by the time counting unit, the random number range is initialized.
