When Signals Lie: Radio Physics and Mobility Insight

Mobility analytics often start with a simple idea: stronger signal means closer user. The real world is not that simple.

Radio waves bend, scatter, reflect, and get absorbed by the materials they encounter. Those physical effects can shift a device's apparent location by tens or hundreds of meters, even when the data pipeline is mathematically correct.

This post is the first in a short series on radio propagation and positioning accuracy. The goal is not to explain every equation, but to show why physics matters and how we validate positioning logic when ground truth is scarce.
