Document Type and Number:
WIPO Patent Application WO/2021/187155
Kind Code:
A1
Abstract:
In the present invention, when a channel frequency is used by another wireless communication device and an operation unit detects a voice sending start operation, a control unit controls a storage unit to store voice data therein until the operation unit detects a voice sending stop operation. When the channel frequency is not used by another wireless communication device and a bit error rate measured by a communication quality measurement unit is less than a first threshold, the control unit controls a communication unit to transmit all pieces of untransmitted voice data among the voice data stored in the storage unit. When the channel frequency is not used by another wireless communication device and the bit error rate is equal to or more than the first threshold and less than a second threshold, the control unit controls the communication unit to transmit divided data with a predetermined length from the head of untransmitted data among the voice data stored in the storage unit.
