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 diagnostics CSV Download page, see Section 8.3.14.
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.
The data used to compute the histogram statistics can be downloaded in an ASCII command
separated variable (CSV) format via the diagnostics CSV Download page, see Section 8.3.14.
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:
•
Running at maximum receive mode
The wireless link is operating at its receive maximum capacity. To confirm that the wireless link
is operating at its maximum transmit capacity either look at the ‘Transmit Modulation Mode’ on
this page or look at the peer wireless units ‘Receive Modulation Mode Detail’ attribute.
•
Running at user-configured Target Modulation Mode
This indicates that the wireless link could operate at a higher capacity but has been limited in
modulation mode by the user from the configuration page.
•
Restricted because Installation is armed
During installation the wireless link is restricted to operate in a low order modulation mode
(BPSK ½). Disarming the wireless units after installation will allow the wireless link to
adaptively select its own operational modulation mode.
•
Restricted because of byte errors on the wireless link
During normal operation the wireless link monitors its performance. If byte errors are detected
during normal data transmission / reception the wireless unit automatically changes the active
modulation mode to a more robust mode in order to reduce the number of errors.
•
Restricted because a DFS channel change is in progress
During Spectrum Management (DFS) channel changes the wireless unit temporarily reduces
the modulation mode to BPSK ½.
•
Restricted due to the low Ethernet link speed
If the Ethernet link speed is less than the instantaneous wireless link capacity then the
modulation mode is optimized so that the Ethernet link speed is satisfied using the most robust
modulation mode.
•
Limited by the wireless conditions
The wireless link capacity is limited by the current wireless conditions e.g. interference, excess
path loss, etc..
