Abstract

See full text

A method and system for time-of-flight (ToF) positioning in an IEEE 802.11 network comprises a responder station to transmit samples of preambles as the preambles are received. The samples represent channel information. The preambles comprise extension high-throughput long training fields (HT-LTFs). An initiator station is arranged to perform a time-of-arrival calculation based at least in part on an analysis of the channel information.
