<p>PROBLEM TO BE SOLVED: To provide a wireless transmitter/receiver with which a cause can be identified when a communication quality is deteriorated. SOLUTION: When packet data are received by a wireless circuit part 12 of a wireless transmitter/receiver 10 on the side of receiving, a control part 13 decides the occurrence of a receiving error from the error detection bit of the packet data and when the receiving error occurs in the received packet data, the control part 13 transmits a retransmitting request signal via the wireless circuit part 12 and a transmitting/receiving antenna 11 to a terminal on the side of transmitting. At the same time, a receiving error accumulation part 14 accumulates a number of times of receiving errors for each radio communication channel. Next, by comparing the distribution condition of the number of times of receiving errors stored in a distribution pattern storage part 16 by causes with the distribution condition of a number of times of receiving error for each radio communication channel accumulated by the receiving error accumulating part 14, a cause estimation part 15 estimates the cause of the occurrence of receiving error and the estimated cause is displayed on a report part 17.</p> |
