This topic lists restrictions that exist for new areas and zones.
When you define a new area or zone, existing tags and tag to zone relationships will not be displayed or logged for the new area or zone. For example, you will need to recreate boundary zones and gates and review any historical data you are interested in. New alerts and tag data will be read and analyzed; however, old events will not be reanalyzed to determine whether a tag is within a newly defined area or zone.
To summarize, old location events that were received by devices that are now in a newly defined area or zone are ignored by the new area or zone. Only new events will be analyzed and displayed for the new area or zone. This also applies to zone-related rules. Since rules evaluate zone entry and exit event, they are not triggered until a tag enters or leaves a zone.
Furthermore, area and zone names must be unique across the Location Awareness Services for WebSphere® Premises Server installation.
