Abstract: A method of wireless ranging between an initiator node and a responder node, involves performing a measurement procedure resulting in a two-way phase measurement between an initiator node and a responder node, the measurement procedure involving the initiator node transmitting an initiator carrier signal; the responder node performing a phase measurement of the initiator carrier signal relative to a responder node clock reference; the responder node transmitting a responder carrier signal; and the initiator node performing a phase measurement of the responder carrier signal relative to the initiator node clock reference, the method further involving calculating a distance between the initiator node and the responder node using as input the two-way phase measurements for the plurality of nominal frequencies; and a clock reference offset correction of the initiator node and of the responder node.

Abstract: A method is disclosed for group ranging in a wireless network. The wireless network comprises a plurality of nodes, including an initiator node and a plurality of responder nodes. The method includes performing, for each frequency in a plurality of frequencies, a measurement procedure involving a two-way phase measurement between the initiator node and each of the responder nodes. The measurement procedure includes the initiator node transmitting a carrier signal having the frequency, each responder node of the plurality of responder nodes receiving and performing a phase measurement of the carrier signal, each responder node of the plurality of responder nodes transmitting a carrier signal having the frequency, and the initiator node receiving and performing a phase measurement of the carrier signal. The method further includes calculating, between the initiator node and each responder node of the plurality of responder nodes, a distance, based on the performed two-way phase measurements.
