5.2 Communications Time
The following charts show communication time on each protocol. It is influenced on practical matters, for
example radio noise, distance between tags, materials tags are on and other environmental matters.
These charts are generated by plotting and linking average of actual communication time on every 5 tags.
Communication time is measured in shielded room with one reader, so that no reflection and no interference
are considered.
You can refer these charts on determining time out value of RQL command. But you must keep in mind actual
communication time on your environment may not correspond to these charts because of the reasons already
described.
