One of the main features of wireless networks is that they are used as transmission medium the radio channels that are affected by a lot of interference. In some cases it leads to a high bit error rate (BER) level in the channel which significantly reduces its throughput. In the article analysis of approaches and appropriate methods for BER measurement in a wireless channel were conducted. It is shown that the methods that are used for BER measurement do not allow calculate BER value with sufficient accuracy. In the article an original model oriented method of BER measurement is proposed. BER calculation is performed using a mathematical model of wireless channel throughput. As the mathematical model is used a modified model of wireless channel with retransmissions. As a basic metric for BER level calculation is used experimentally measured throughput of the wireless channel. Experimental assess of method accuracy was conducted. Analysis of method accuracy shows that the proposed method allows with a high accuracy calculate the average value of the wireless channel BER level.
