Also, a second geo-location of the mobile device at a second time is identified. A potential travel path of the mobile device is determined between the first geo-location and the second geo-location. The potential travel path is in at least two dimensions. A determination is made as to whether the potential travel path intersects with the predetermined geo-fenced region. If the potential travel path intersects the predetermined geo-fenced region by an amount that satisfies an intersection requirement, a determination is made that the mobile device entered the predetermined geo-fenced region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Retrospective path analysis","description":"To determine whether a mobile device has entered a geo-fenced region, a first geo-location of the mobile device at a first time is identified.
