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.
