RTLS – Indoor Location System

Problem

Accurate indoor positioning is challenging due to the lack of GPS and the complexity of indoor signal propagation.

Solution

Worked on integrating UWB-based positioning hardware with backend services and visualization tools, contributing to new features and system stability.

Architecture & Approach

UWB anchors communicate with mobile tags, transmitting data over TCP to a central backend. Position data is processed and visualized through a web interface.

Key Tradeoffs

• System accuracy depends heavily on anchor placement and calibration
• TCP simplifies communication but requires robust error handling
• Real-time updates must balance latency and stability

What I Learned

• Indoor positioning systems require tight coordination between hardware and software
• Integration work is critical in complex systems, even when core algorithms are pre-existing
• Early exposure to full-stack and embedded work accelerated learning significantly
