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.

As the holidays approach, it is natural to look back at the path we’ve traveled. For Telcofy, 2025 wasn’t just a year of business development; it was a year of initiative, conception, and birth.

From Vision to Momentum​

We've returned from the Smart City Expo World Congress 2025 in Barcelona energized, inspired, and more determined than ever to drive the future of data-driven urban innovation.

With Telcofy's vision of creating better and more sustainable societies, attending Smart City Expo World Congress in Barcelona this November is a natural step.

When statisticians, telecom operators, and data scientists meet in Paris, you can be sure of one thing: every signal matters.

When millions of people move through a city each day, mathematical patterns emerge that reveal how societies organize themselves.

Human mobility science studies these aggregate patterns - not where individuals go, but how populations flow and cluster across space and time. It's the foundation for understanding disease spread, urban planning, and emergency response.

Human mobility patterns hold the key to building better cities, managing crises, and understanding how societies function. Yet the field of mobility science - decades of brilliant academic research - remains locked away from those who could use it to improve lives.

We founded Telcofy to bridge that gap.
