Receive Data Rate The data rate in the receive direction, expressed in Mbps and presented as: max, mean, min,
and latest histogram format.
The histogram is calculated over a one hour period. If the equipment has been running for less than one hour
then the histogram is calculated over the current elapsed time.
The data used to compute the histogram statistics can be downloaded in an ASCII command separated variable
(CSV) format via the download diagnostics page, see section 6.3.9.
Transmit Data Rate The data rate in the transmit direction, expressed in Mbps and presented as: max, mean,
min, and latest histogram format.
The histogram is calculated over a one hour period. If the equipment has been running for less than one hour
then the histogram is calculated over the current elapsed time.
The data used to compute the histogram statistics can be downloaded in an ASCII command separated variable
(CSV) format via the download diagnostics page, see section 6.3.9.
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.
The data used to compute the histogram statistics can be downloaded in an ASCII command separated variable
(CSV) format via the download diagnostics page, see section 6.3.9.
Transmit Modulation Mode The modulation mode currently being used on the transmit channel. The number in

protocols.
The data used to compute the histogram statistics can be downloaded in an ASCII command separated variable
(CSV) format via the download diagnostics page, see section 6.3.9.
Available Channel The available channels attribute describes the number of usable channels that have been
measured by the Dynamic Frequency Selection (DFS) algorithm.
