3.2 Communications Time
Communications time varies for several reasons
such as the actual noise environment and the
distance between tags and antennas. The chart
below shows the communication time vs. the
number of tags in the antenna read range. One may
use the communication time value as a reference
when setting time out values in the RQL command.
