Figure 1.5 The Fictional AXCESS Hospital Facility.
With respect to the Hospital site map, suppose that there are various Axcess tags, activators,
readers, and cameras located throughout the facility. Some tags may be attached to assets and
equipment that is not supposed to move. Other tags may be attached to people or assets that
are expected to move throughout the facility. We are immediately faced with a problem. How
do we distinguish between areas of interest where various types of RFID events occur?
Distinction is achieved with the “Zone”. The Zone is both a physical entity and an idea. Zones
are somewhat constrained by the proximity of tags to activators and readers. Zones are not
necessarily bound by walls, ceilings, or floors, because electromagnetic waves can be absorbed,
reflected, or pass through walls, ceilings, and floors. A Zone could also be defined outside in
an open area. However, with AXCESS’ RFID experience and expertise, Zones and the RFID
events that occur with respect to them may be closely correlated with a room, rooms, or area.
So here, for purposes of illustration and introduction we will confine Zones to well-defined
areas. Below, in figure 1.6, we see a “Zone” that consists of a corridor (the idea), activators,
and a camera. Zones will have been determined by your administrator.
