4.1.2.3 Statistics
The statistics gathering is used for estimating link load intensity. The amount of
packets sent and received, and the number of retransmissions is shown for each
MAC address participating in the data exchange.
The statistics output is presented in the picture below.
The following decisions can be made by analyzing the outputted parameters:
 If the number of repeated packets is comparable with total number of packets
that means that you might have an interference source on the selected
frequency. For normally operating link the percentage of repeated packets
should not exceed 10%. It is extremely important to obtain a permanent zero
value for the average number of repeats per packet. If the value is not zero that
means that the link is NOT working properly and requires further
improvement
 If total percentage of repeated packets and the percentage of packets that were
repeated at least once are close to each other that might mean that you have
