Abstract: Systems and methods for system for tag polling are disclosed herein. An example system includes: a tag associated with an asset; an anchor configured to poll the tag at a first transmission rate and determine an angle-of-arrival (AOA) based on signal data received from the tag; and a server communicatively coupled with the anchor. The server may be configured to: receive first information corresponding to the tag, the first information being indicative of one or more first instances where the anchor polls the tag at a second transmission rate that is different from the first transmission rate. The server may further be configured to receive, from the anchor, a tag listing that includes the tag, determine a first instance occurrence for the tag based on the first information, and transmit a request to the anchor that causes the anchor to poll the tag at the second transmission rate.
