Abstract: There is disclosed a system for locating an object on a surface waveguide. The surface waveguide is made of one or more 1D wires and/or 2D waveguides comprising conductive elements arranged in patterns. Emitters with known positions can couple with receivers coupled with the surface waveguide. The position of receivers can be determined, for example by multilateration or signal strength indication. Conductive elements can be sprayed or sewed or otherwise deposited onto surfaces such as a ground floor, a sidewalk or a road lane. Described developments comprise the use of absorbers, protective layers, unidirectional emitters, contactless coupling, and various arrangements comprising frequency-selective layers, arrangements in lattices, treillis or anisotropic surfaces. Signal processing aspects and software embodiments are also described.

Abstract: Examples disclosed herein relate to the scheduling and transmission of timing measurements between mobile computing devices in an area to determine the devices' locations. A bulk fine timing measurement (BFTM) allocation message is generated by a scheduling mobile computing device that identifies other mobile computing devices in the area. The BFTM allocation message generated by the scheduling mobile computing device indicates a time of delivery (TOD), a scheduling order for the identified mobile computing devices, and a contention-free period for the mobile computing devices to transmit the timing measurement messages. The mobile computing devices generate BFTM timing message, which include times of arrival (TOAs) or propagation timing estimates, associated with message from other devices. The scheduling order indicates a sequence of transmissions (e.g., a forward and reverse sequence) in which the responding mobile computing devices are to transmit the BFTM timing messages, which are used in location-detection services.
