Document Type and Number:
WIPO Patent Application WO/2024/084840
Kind Code:
A1
Abstract:
Provided are a distance measurement method and a distance measurement system which, when the distances between a plurality of communication stations are measured, can shorten the processing time required for distance measurement. The distance measurement method is for the distance measurement system that includes: a first communication station; and a plurality of second communication stations that transmit signals of a plurality of frequencies to-and-from the first communication station to measure the distance to the first communication station. When the plurality of second communication stations receive a request signal from the first communication station, the second communication stations transmit distance measurement data representing the measured distance to the first communication station.
