A device may determine a null data packet (NDP) frame comprising one or more fields. The device may determine a first long training field (LTF) and a second LTF, the first LTF and the second LTF being associated with a first frequency band of the NDP frame, wherein time domain LTF symbols of first LTF and the second LTF are generated using different LTF sequences. The device may determine a third LTF and a fourth LTF, the third LTF and the fourth LTF being associated with the a second frequency band of the NDP frame, wherein time domain LTF symbols of third LTF and the fourth LTF are generated using different LTF sequences. The device may cause to send the NDP frame to an initiating or a responding device. The device may cause to send a location measurement report (LMR) frame to the initiating or the responding device, wherein the LMR comprises timing information associated with the first frequency band and the second frequency band."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Long training field sequence security protection","description":"This disclosure describes systems, methods, and devices related to long training field (LTF) sequence security protection.
