Radio frequency identifier tag unit operation
In some aspects, a reader may transmit, to one or more radio frequency identifier (RFID) tags, a continuous wave in accordance with a unit operation, wherein the unit operation is associated with one or more of an amount of time or a number of unit steps associated with one or more RFID sessions or one or more RFID sub-sessions. The reader may receive, from each of the one or more RFID tags, a response during the unit operation. Numerous other aspects are described.

7 . The reader of claim 1 , wherein the one or more processors are further configured to cause the reader to:
determine one or more radio frequency parameters; and
determine the amount of time or the number of unit steps for the unit operation in accordance with the one or more radio frequency parameters.
8 . The reader of claim 1 , wherein the one or more processors are further configured to cause the reader to determine the amount of time or the number of unit steps for the one or more RFID sessions or the one or more RFID sub-sessions.
9 . The reader of claim 1 , wherein the one or more processors are further configured to cause the reader to determine a desired transmission power in accordance with one or more physical layer conditions.
10 . The reader of claim 1 , wherein the one or more processors are further configured to cause the reader to determine a transmission frequency and a dwell time.
11 . The reader of claim 1 , wherein the one or more processors are further configured to cause the reader to determine a final duration and a transmission power for the unit operation.
12 . The reader of claim 1 , wherein the one or more RFID sessions or the one or more RFID sub-sessions include one or more of:
a single tag inventory search;
a multi-tag inventory search;
