Response Preamble

    Response preamble is a string of bits added in front of a response(ACK) frame before transmitting. This preamble prolongs the response frame in order to reduce the chances of the response frame being missed by the receiving radio. This feature sets the duration of the preamble. This duration needs to be increased as the number of scan members increases on the target. This value can be increased in all the transmitting radios if scanning radios are often missing data. However, a larger preamble occupies the channel longer. Therefore, increasing this value will increase the success rate of data received while other radios are scanning, but will decrease the amount of data that can be transmitted on the channel.
