ABB PP826A 3BSE042244R3 Operation panel

This parameter controls whether the RLX2 Repeater will act as a Parent to other RLX2 Repeaters. Selecting ‘No’ will disguise the RLX2’s SSID thus preventing other 803.11 devices from finding it. Fast Roam applications take advantage of this where it is not desirable to have anything connect to an RLX2 that is itself, moving and roaming.

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.

Roaming Parameters Roaming

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

After a selection is saved 

and return to the Radio Network Settings panel, notice the selection is indicated under the Parent Link button.The Automatic Parent Selection algorithm uses a calculation to create a cost for each possible parent radio that it detects. Once per second, the RLX2 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 Available Parent web screen. The cost calculation is based not only on the strongest signal, but on several other factors including Number of Hops to provide optimum network communication.
