Methods, systems, and apparatuses for reading tags of tag populations are described. Rather than interrogating a tag population in a single query round, interrogations of tag populations are performed using reduced transmit power levels over multiple query rounds, each query round reading a portion of the tag population. In this manner, an overall power amount expended to transmit interrogations signals is reduced, while maintaining a substantially similar read rate as in single query round interrogations. |
