Beschreibung
Zusammenfassung:	A method of secure wireless ranging between a verifier node and a prover node comprises performing a measurement procedure resulting in a two-way phase measurement and a round-trip time measurement between the verifier node and the prover node. The measurement procedure comprises the verifier node transmitting on the frequency a verifier packet, the prover node receiving the verifier packet and performing a phase measurement of a verifier carrier signal and a time-of-arrival measurement of a verifier frame delimiter, the prover node transmitting a prover packet, and the verifier node receiving the prover packet and performing a phase measurement of the prover carrier signal and a time-of-arrival measurement of the prover frame delimiter. The method further comprises calculating a distance between the verifier node and the prover node based on the two-way phase measurements and the round-trip time measurements for the plurality of frequencies.
