PinPoint T20 Tags can be read at a distance of 80 meters (250 feet) under ideal
conditions. This specification provides margin for the Tag to be read in a wide
variety of typical indoor conditions, such as through walls. Specifically, the Tag
is designed to be powerful enough to be read through sheet rock walls, but
lacks the power to be read through concrete and metal typically found in floor
construction. The ability to be read through walls allows Cell Controller anten-
nas to be placed in a hallway, and read the tags in adjacent offices. The inabili-
ty to be read through floors ensures that a Tags location will always be identi-
fied on the correct floor. This is consistent with many applications, where great
precision is not needed as long as the floor is correctly identified.
The Tags antenna is linearly polarized. In combination with the circularly polar-
ized Cell Controller antenna, the result is that the tag is insensitive to rotation
around the radial axis.
The T20 Tag is normally attached to assets or worn as a badge. Therefore, to
conserve power the Tags antenna is designed to emit power from the front of
the Tag only. The HPBW (Half Power Beam Width) is approximately 80 degrees
on the vertical axis, and 120 degrees on the horizontal axis. Multipath environ-
ments typical for indoor applications usually enable a Tag to be read at dis-
tances up to about 20 meters, even if the Tag is facing away from the Cell
Controllers antenna.
