Enhanced timing measurement techniques for determining distance in wireless networks

摘要

A method of determining a distance between mobile wireless devices can include determining a format and bandwidth supported by an initiating Station (STA) and a responding Station (STA) and exchanging one or more sets of Null Data Packet (NDP) frames between the initiating Station (STA) and the responding Station (STA) using the determined format and bandwidth. The distance between the initiating Station (STA) and the responding Station (STA) can then be determined based on timing measurements of the one or more sets of Null Data Packet (NDP) frames exchanged between the initiating Station (STA) and the responding Station (STA).
