Pkt Re-transmissions

the radio on the active channel. Retransmissions can 
indicate that the client is not receiving ACKs from the MAP 
radio.

Utilization

send on a channel while continuously sending fixed size 
frames over a period of time. The number of packets that 
are successfully transmitted indicates how busy the 
channel is.
