AI Technical Summary
Technical Problem
Conventional localization devices suffer from inaccuracies in determining the angle of arrival (AOA) due to peak misidentification and inefficient battery life, as increasing transmission frequency to improve accuracy significantly depletes label batteries.
Method used
Implementing a system that selectively adjusts transmission rates for labels based on priority instances, allowing accurate AOA determination while preserving battery life by transmitting at a higher rate during priority events.
Benefits of technology
Ensures accurate AOA/location determination during priority instances while conserving label battery life, enhancing the efficiency and reliability of localization systems.

Abstract
Systems and methods for a label query system are disclosed herein. An exemplary system includes: a label associated with a good; an anchor configured to query the label at an initial transmission rate and to determine an angle of arrival (AOA) based on signal data received from the label; and a server communicatively coupled to the anchor. The server can be configured to: receive initial information corresponding to the label, the initial information indicating one or more initial instances in which the anchor queries the label at a second transmission rate different from the initial transmission rate.The server can further be configured to receive a label listing from the anchor containing the label, to determine a first instance occurrence for the label based on the first information, and to send a request to the anchor causing the anchor to query the label at the second transmission rate.
