4.2 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.
