until 6 receivers are left.
To configure the system to enable receiver pruning based location algorithm:
1 Start Hub Administration and Management application, click Administration.
2 In the Administration view, select the Advanced tab
3 Check or un-check Enhance Locate Algorithm via Receiver Pruning to enable or disable the
receiver pruning based location algorithm.
4 Click Save for the user settings to take effect.
Best Effort Pruning
Best effort pruning is an effort to balance locate accuracy and volume. It can be enabled/disabled
only when receiver pruning based locate enhancement algorithm is enabled. Best effort pruning,
when enabled, changes the behavior of DQI filtering, if selected, in virtual group configuration.
In this case, instead of filtering calculated tag locates, the DQI filter serves as the best effort goal
for the pruning algorithm. If an initially calculated tag locate fails to meet the virtual group
requirements, such as outside of virtual group boundary or with DQI higher than the DQI
threshold, the pruning algorithm starts to optimize the tag locate by removing outlier receivers
one by one. If the final tag locate produced by pruning algorithm has DQI higher than the DQI
threshold, the Hub will send the tag locate in the output data stream, as oppose to dropping the
tag locate and outputting a presence data in the output data stream.
Best effort pruning only affects tag locate calculation inside a virtual group with DQI filtering
enabled.
