Description
Preferred Parent
RLX2 radio will select its parent from a list of possible parents specified
by the user. The user can list up to eight radios to choose from.
Best in List
When Best in List is selected the radio will select its parent using
the "Automatic Parent Selection" algorithm, but it will limit the
selection to the list of radios in the list. Therefore, the radio in the
list with the lowest cost according to the algorithm will be chosen
as its parent.
Follow List Priority
When Follow List Priority is chosen the radio will select its parent
from the list giving preference to the 1st entry followed by the 2nd
entry and so on.
Parent Selection Parameters
Signal Strength
Threshold
When the signal from a parent reaches a high enough value, a stronger
signal will not improve the quality of the link any further. For signals
that are above that threshold, only fewer hops from the Master give
preference. The threshold can be adjusted here.
Rate to Parent
The default setting is Auto which allows the radio to select the best rate
to use to the parent radio, and adapt over time. Specify a fixed rate
rather than auto for example if the link to the parent has a low signal
strength in which case fixing a lower rate can improve performance.
The actual rate used between this radio and its parent is the lower
value of this setting and the Max Data Rate setting in the parent (see
Max Data Rate). So use these two controls in conjunction if desired to
tailor the rate of each parent link.
Roaming Parameters
Optimize Fast Roaming
Parameters
In typical Fast Roam applications a Repeater is installed on a mobile
pallet or platform and a set of Master units forms a backbone
infrastructure network, through which the Repeater must roam. To
obtain fast roam times, Spanning Tree must be disabled and SSID's
not hidden on the Master. The Repeater should be configured to not
allow child Repeaters and to use a Signal Strength Threshold set high
enough such that RSSI is used to determine the link cost to a parent.
Checking the checkbox in this section automatically sets these
parameters accordingly along with a predetermined optimum value for
the cost threshold. Unchecking it will revert the parameters to their
previous values before the check box state was saved.
Note: All Spanning Tree configurations and Hide SSID must be
disabled manually on all Master units as this dialog box is only
accessible when in Repeater mode.
It is always possible to subsequently change any of these parameters if
it is so desired, for example to set a different value for the Signal
Strength Threshold. If this is done then the control will not display as
checked as it will only display as checked if all three parameters have
the preset values.
Save
Saves the changes and updates the radio configuration.
Cancel
Discards the changes without updating the radio configuration.
