3. eNode Installation
3.1. eNode Positioning
Figure 14 illustrates the eNode, and its corresponding view
angle. Following are the key considerations to review when
installing eNodes:
a) Distance between the eNode and tags in the
interrogation space
b) Size of the interrogation space
c) Obstructions – between eNode and interrogation
space
d) Orientation and pointing of the eNode with respect
to the interrogation space
The view angle of the eNode is in compliance with FCC
& ETSI specification. The excitation range of the tags is
highly dependent on tag manufacturer, tag placement, tag
orientation, and the content of the tagged material. Typical
tags receive sufficient power to turn on at greater than 30
feet (9.1 meters) of the eNode in free space, meaning that
the tag is held in mid-air and not attached to any material.
3.2. eNode Cabling
Figure 15 illustrates the Single-Port eNode, showing the RF and I/O connectors. Connector specification is provided in
the following table.
