Equation 2 - Link Loss
Receive Data Rate: The data rate in the receive direction, expressed in Mbps and presented
as: max, mean, min, and latest histogram format.
Transmit Data Rate: The data rate in the transmit direction, expressed in Mbps and
presented as: max, mean, min, and latest histogram format.
Receive Modulation Mode: The modulation mode currently being used on the receive
channel. The number in brackets after the modulation mode and coding rate string is the
effective data rate available to all MAC layer protocols.
Transmit Modulation Mode: The modulation mode currently being used on the transmit
channel. The number in brackets after the modulation mode and coding rate string is the
effective data rate available to all MAC layer protocols.
Receive Modulation Mode Detail: The receive modulation mode detail presents to the user
the reason why the wireless link is not operating at the maximum capacity (modulation mode).
Values that can be presented in this field are:
