Publication number: 20160327628Abstract: Various embodiments provide a method and apparatus for determining non-line of sight (NLOS) bias estimation based on estimated NLOS bias distributions at a number of anchors and the time of arrival (ToA) of a number of tag messages received at the anchors. In particular, using anchor redundancy, tag locations corresponding to the tag messages are estimated based on the NLOS bias distributions and the ToA and then the tag locations are used to update the NLOS bias distributions. The process of determining tag locations and updating the NLOS bias distributions is repeated until the NLOS bias distributions converge.Type: ApplicationFiled: May 7, 2015Publication date: November 10, 2016Applicant: Alcatel-Lucent USA Inc.Inventors: Fernando Perez-Cruz, Howard Huang

Publication number: 20160291127Abstract: A capability for localization of a wireless tag based on wireless gateway association information uses a wireless tag supporting multiple states and wireless gateway association information associated with the wireless tag to control localization of the wireless tag. The wireless tag may support an unconnected state in which the wireless tag communicates location tracking information using a wireless beacon signal which may be detected by various wireless gateways and a connected state in which the wireless tag communicates location tracking information via one or more connections with one or more wireless gateways. The wireless gateway association information may include wireless gateway lists (e.g., whitelists, blacklists, or the like), association rules, notification rules, or the like. The wireless gateway association information may be used to control transitions of the wireless tag between the unconnected state and the connected state, to control notifications for the wireless tag, or the like.Type: ApplicationFiled: March 31, 2015Publication date: October 6, 2016Applicants: Alcatel-Lucent USA Inc., Alcatel LucentInventors: Howard Huang, Irwin Kennedy, Surya Mattu, Richard Abbot, Jonathan Ling, Chih-Kuang Lin
