Anterus™ RFID Solution
Conclusions
Two basic conclusions can be made from examining FIG. 9:
First, a very strong signal implies the person or object is very close to the reader. This is simply due to the fact that it is impossible to receive a strong signal from far away.
Second, a tag with a weak signal is likely to be far away, but can also be near due to reductions in strength that can come from one or more of the environmental factors described above.
For example, for a reading of 150, the distance between reader and tag is almost certainly less than or equal to 20 feet. A tag at 20 feet is likely to have a signal strength reading between 150 and 70, and possibly weaker if the tag's view is obstructed.
