原因是，无线装置要发送数据并等待来自接收数据的另一个无线装置的应答。
The reason is that one radio will send out data and wait for an acknowledgment from the other radio that the data was received.
如果无线发送装置在一定时间内收不到应答，就假定数据丢失，并且将重新发送数据。
If the transmitting radio doesn't receive the acknowledgment in a certain amount of time, it will assume that the data was lost, and it will resend it.
