Transmit Data Rate: The data rate in the transmit direction, expressed in Mbps and
presented as: max, mean, min, and latest histogram format. The max, min and latest are true
instantaneous measurements, the mean is the mean of a set of one second means.
See note 15. Expected data rates can be found in section 4.1.4 "Aggregate Ethernet
throughput rate v maximum 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. The max, min and latest are true
instantaneous measurements, the mean is the mean of a set of one second means.
See note 15. Expected data rates can be found in section 6.1.4.
Link Capacity: The maximum aggregate data rate capacity available for user traffic,
assuming the units have been connected using Gigabit Ethernet. The link capacity is variable
and depends of the prevailing wireless conditions as well as the distance (range) between the
two wireless units. When the link is idle and in 'IP Mode' the wireless link will adaptively
configure itself into a lower latency mode, this will cause the displayed link capacity and
aggregate data rates to diverge. This is because the aggregate data rate displays the
instantaneous capacity of the wireless link not the maximum potential capacity of the link as
displayed by link capacity.
Transmit Modulation Mode: The modulation mode currently being used on the transmit
channel. Details on the modulation modes can be found in section 21.1 "System
Specifications".
Receive Modulation Mode: The modulation mode currently being used on the receive
channel. Details on the modulation modes can be found in section 21.1 "System
Specifications".
Receive Modulation Mode Detail: This supplies the user with information regarding the
receive modulation mode in use. Possible values are:
•
Running at maximum receive mode
•
Running at user-configured Max Modulation Mode
•
Restricted due to byte errors on the wireless link or local Ethernet Tx Fifo Drops
•
Restricted because a DFS channel change is in progress
•
Restricted due to telecoms acquisition mode
•
Restricted due to the low Ethernet link speed
•
Limited by the wireless conditions
