Abstract
A mobile tag reader that may be configured to wirelessly communicate with a security tag is provided. The mobile tag reader may include a position estimator, which includes processing circuitry configured to receive information indicative of at least a first read event associated with a first antenna beam pattern and a second read event associated with a second antenna beam pattern emitted by the mobile tag reader. The processing circuitry may be further configured to identify an overlap area between at least the first antenna beam pattern and the second antenna beam pattern. The processing circuitry may be further configured to determine an estimated location of the security tag based on the overlap area.
