About Cell Controllers
The Cell Controller is the primary data
collection tool of the 3D-iD sys -
tem. The Cell Controller coordinates the Antennas broad-
cast s and then analyzes the signals returned by the Tags.
To do this, the Cell Controller broadcasts spread spectrum
signals at 2.44GHz to the 3D-iD Tags via it s att ached
Antennas. It then measures the total time transpired until
the return signals (at 5.77GHz) are received from the Tags.
Using this information it calculates the distance the Tag is
from the Antenna, called Tag Antenna Distance (TAD) data.
The Cell Controller sends the data it generates to the
V iewPoint Software via a st andard ethernet link. The soft-
ware will, using the dat a collected from several Antennas,
accurately determine a Tag s location.
