From that source:

> GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius

Smartphones were typically optimized for speed and battery life, not accuracy. Now that Multi-Band GPS is available on high end smartphones, they tend to be more accurate.

Also almost every smartphone I know of has acceleration sensors and can do Kalman filtering of the GPS position to achieve a much higher accuracy in practical use, even if the individual measurements are only accurate to ~5 meters.

They add fuzz to RSSI algos due to accelerometers trying to predict direction ofmotion for telemetry aiming.

swarm that on that backend with GPS tlemetry and typical rssi from cell towers, and the IMEI - and you have precise targets... with bios on the tracker (phone) - cams, gait, finger, face, voice, face... May as well start developing smart fabric... Oh wait...
