This topic explains gates and their role in controlling access within zones for Location Awareness Services for WebSphere® Premises Server.
Gates provide access control for the entry way and exit of a zone. With gates, you can associate one device that specifically monitors the entry to or exit from a zone. Gates are defined after defining the devices for the event provider (hub).
When monitoring zones in areas, you will need to define the gate twice, for the zone and for the area. Otherwise, Location Awareness Services for WebSphere Premises Server cannot correctly monitor tag counts for the zone and area.
