2.2.6 Parent Selection
Parent selection allows repeater or client mode RLXIB-IHN-W radios to join a
wireless network using a predefined link selection method as defined in these
pages. At least one radio in the wireless network must be configured as a
Master, in order to define the operating channel and security of the network.
The Automatic Parent Selection algorithm uses a calculation to create a cost for
each possible parent radio that it detects. The following graph describes how the
cost is calculated when the signal strength threshold is set to -60 dBm.
Once per second, the RLXIB-IHN-W radio evaluates the link it has to its parent to
determine if this link is the best parent to use. A cost is calculated for each entry
and can be seen in the column labeled "Cost" in the preceding table. The cost
calculation is based not only on the strongest signal, but on several other factors
to provide optimum network communication. There is built in hysteresis to
prevent frequent link fluctuations.
When a repeater is not associated in the network, it will scan the available
channels for potential parents.
The following parameters allow you to specify additional parent selection rules.
