Patent number: 11856478Abstract: A method of determining a range between two devices, which can for instance be wireless devices, such as handheld devices. The method performs a double-sided two-way ranging protocol at the two devices. This protocol causes the two devices to transmit and receive signals, with a view to determining the range between the two devices, using a two-way ranging methods, where each of the signals is a composite tone generated as a composition of two waveforms that are timewise separated by a gap to form a bipolar waveform. The gap is a zero or low-amplitude signal, contrasting with the two waveforms. The particular pattern in the correlation footprint eases the determination of the time of flight. The method can be used to measure social distancing.Type: GrantFiled: August 25, 2021Date of Patent: December 26, 2023Assignee: International Business Machines CorporationInventors: Lior Limonad, Dean Haber, Ashafaaq Minhas, John Maxwell Cohn, Marc PH.
