1. A method comprising:
determining, by a computing device, a plurality of Time-of-Flight (ToF) values between a first service end point and a second service end point, wherein each one of the plurality of ToF values is derived from packets transmitted via different beamforming vector patterns at the first service end point and the second service end point, and wherein determining the plurality of ToF values comprises determining the plurality of ToF values in response to determining that a Non-Line-of-Sight (NLOS) condition exists between the first service end point and the second service end point;
determining a minimum ToF value of the plurality of ToF values; and
determining a distance between the first service end point and the second service end point based on the minimum ToF value.
