Figure 7.8. Experimental setup2 illustrating blocking.<br />
In the Figure 7.10 we have plotted the Sirit Reader power and the Blocking<br />
Reader power with the help of the Friss free space power equation. This is the<br />
theoretical power value not considering any path losses or any multipath constructive<br />
and destructive interference. Here also we can see some interesting patterns. The<br />
Sirit reader states reading the Tag when the Tag is 0.9m away from the Blocking<br />
Reader and then stops reading. Later in next 0.3m that is 1.2m it starts reading<br />
again and stop. This pattern repeats for 1.5m but this time the sirit reader power is<br />
soo high that the blocking reader effects are overcome.<br />
