FIELD: data processing.
SUBSTANCE: invention relates to systems for determining location. Method and system for positioning using calculation time (ToF) in IEEE 802.11 network includes responding station, which transmits preamble samples as received preambles. Samples are channel information. Preambles contain advanced preparatory elongated fields (HT-LTFs) of higher capacity. Initiating station is configured to perform calculation of time of arrival of signal based on at least partial analysis of channel information.
EFFECT: improved method of determining location in closed rooms.
