1. A method comprising:
recording, at a receiving device, a plurality of parameters associated with fine timing measurement (FTM) frames exchanged between a sending device and the receiving device by:
receiving a request FTM frame from the sending device;
recording, for the request FTM frame from the sending device, a received signal strength indicator (RSSI) value, a frame timestamp, a time of departure (ToD) value, a time of arrival value (ToA), a ToD error value, a ToA error value, and a burst window parameter value; and
performing an iterative FTM burst sequence according to the burst window parameter value;
identifying, using the recorded plurality of parameters, a device profile for the sending device comprising at least one of a chipset type, an operating system (OS), and OS traffic schedule variations;
determining, using the device profile, a behavior filter for FTM traffic from the sending device; and
filtering FTM traffic from the sending device according to the behavior filter.
