Abstract:
1. A wireless transmitter device having an upper limit of an accumulated time for data transmission per predetermined duration corresponding to a predetermined maximum accumulation time, comprising: a first timer for keeping time until a timeout value, said first timer starting when said device starts sending a wireless signal and stopping when said first timer reaches the timeout value; and a second timer for measuring an accumulation time of the data transmission of said device during a period from said first timer starting to said first timer stopping, wherein the timeout value is derived by dividing the accumulation time measured with said second timer by a transmission time ratio based on said predetermined duration and said upper limit of an accumulated time for data transmission per the predetermined duration, and wherein the device further comprises a controller for inhibiting the data transmission of said device until the time measured by said first timer reaches the timeout value either if it is determined that the timeout value is substantially equal to or larger than a threshold value, or if it is determined that, if said device is requested to send other data, a timeout value which is calculated taking into account time for sending the data is substantially equal to or larger than the threshold value.
