Class 1 Gen 2 Q value

Q value sets the number of response slots available for the tags being inventoried (number of slots = 2Q). It is actively managed during an inventory round, but starting with an appropriate Q decreases the time necessary to perform an inventory. Initial Q values should be set to generate 1/3 the number of slots compared to the maximum number of tags expected for a given inventory read attempt.

For example, if the application can have a maximum of 50 tags for a given read attempt, Q should be set to 4 ( 50/3 = 16.6666, 24 = 16). If the application can

have a maximum of 150 tags for a given read attempt, Q should be set to 5 (150/3 = 50, 25 = 32).
