7.5.3 Blocking Envelope around the Blocking Reader<br />
In the setup show in the Figure 7.13 the Sirit Reader and Blocker Reader is fixed<br />
with distance between them 2.1m. The Tag is moved around the Blocker Reader to<br />
not the maximum blocking distance. The value of the Vapc is 2.6V hence the Blocking<br />
Reader is radiating a power of about +21dBm. Here at each angle of 30 degree the<br />
Tag is moved closer and away from the Blocking Reader and a maximum distance<br />
where the Sirit Reader just starts to read is noted down.<br />
