Implementing Directionality Feature


Directorial intelligence is the ability to discern whether a tagged object is coming or going, that is entering or leaving a room, crossing a choke point or even entering a trailer from a given dock door.  This logic can be implemented a number of ways based on your use case:


If a single reader is managing all the read points (antennas) as depicted in the schematic D1 below, then this would be classified as basic configuration. The antennas in each zone would be named the same so as to enable net change feature as a group, and there would be IMOVE rules setup for each antenna.  During each read cycle, a given tag will only register on the antenna where it is seen the strongest thus this assists greatly in determining which side of the threshold (or zone) it is on.

If read points are being managed by multiple readers, a different logic is deployed as it cannot be determined by a single reader which antenna is seeing the tag the strongest (e.g. the winner) and thus which side of the Zone the tag is on. This logic is designed when deploying multiple zones whereas each read point in the zone (such as inside perimeter of a room) could be managed by different readers such as a choke point In example D2, Zone A is managed from Reader R1 and Zone B is managed from Reader R2. So in this case you don't have the advantage of the strongest antenna wins because read points are spread over multiple physical readers.  Refer to the RFDDTAG binding that details out how this is setup.
