An example method includes receiving, by a first wireless communication device having a plurality of antennas disposed at a localized position, a plurality of fine timing management (FTM) messages from a second wireless communication device. The example method includes transmitting, by the first wireless communication device, a plurality of FTM responses to the second wireless communication device. Each of the plurality of FTM responses may be transmitted using a different antenna of the first wireless communication device. The example method also includes estimating a range between the first wireless communication device and the second wireless communication device based at least in part on the plurality of FTM messages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ranging over multiple antennas","description":"Methods, systems, and devices are described for wireless communication.
