7.3.2 Results for Tag Response Range<br />
The Figure 7.4 shows Tag RN16 voltage with respect to distance from the<br />
Blocking Reader. As BR moved away from the Tag the voltage value of the Tag<br />
response is reducing. At 1.1m the Tag stops responding to the BR query. There is an<br />
interesting pattern after 1.1m. It is too complex to say the reason for this pattern.<br />
We can say it might be due to multi-path, the places where Tag is not responding,<br />
it might have destructive interference. Finally we conclude that the maximum Tag<br />
response range is 1.1m for a +6-9dBm power of BR.<br />
