WHY BENCHMARKING METHODOLOGY?
-
Lacking scientific guidelines by which the design of an RFID system can be assessed before implementation.
-
Dependency of RF performance on its environments,
-
Vulnerability of RFID devices due to physical characteristics
-
System influenced by operational characteristics; distance between tags, its packaging..
-
Ambient noise due to reflection, refraction, diffraction and absorption by structures and even human bodies.
WHAT ARE THE CHALLENGES?
Need intensive experimentation of controlled variables:
For example, test different number of tags (1, 10, 20, 50, 100, …)
-
different orientation (0, 30, 60, 90, random, …)
-
different height of antenna (0.5/1/2/3 m, …)
-
different emission power levels
-
different distances
-
different frequencies, and so on.
Each combination is to be tested many times so as to obtain statistically sound results.
