Typical phone GPS accuracy is 10–30 m.

How it's calculated

  • • Recommended radius = site base radius + (2 × expected GPS accuracy).
  • • Base radius by site type: office 50 m, retail 75 m, warehouse 150 m, field 300 m, campus 500 m.
  • • Guidance only — tune to your actual site footprint and observed device accuracy.
