Redpoint delivers SIL2-compliant RTLS for large-scale autonomous mobile robot environments

The Problem

Some of the world’s leading AGV manufacturers deploy tens of thousands of robots every month in warehouse environments. While AGVs can increase productivity by up to 300%, safety protocols require the entire fleet to stop whenever human crews enter the area. This leads to frequent and costly shutdowns—especially in high-volume operations—creating tension between safety and efficiency.

The Solution

Redpoint’s RTLS makes crew locations visible to AGVs, enabling intelligent avoidance maneuvers and route adjustments. The system also feeds real-time data to central dispatch for smarter task allocation—ensuring worker safety without halting operations.

Technical Challenges
  • High node density and mobility: Hundreds or even thousands of fast-moving AGVs operating simultaneously
  • Extreme reliability: Required >99% system reliability for functional safety (SIL2), despite UWB’s low transmission power

Meeting SIL2 safety standards in wireless environments—especially at UWB’s low power levels—posed a serious engineering challenge.

The Results

Redpoint engineered purpose-built wireless protocols optimized for safety-critical environments. These protocols mitigate congestion and interference, while delivering:

  • Centimeter-level accuracy
  • Millisecond latency
  • 99.5% reliability

The system is fully compliant with SIL2 and Pld standards. Today, it’s deployed in tens of thousands of AGVs, increasing operational efficiency by at least 4%, with even greater impact during peak seasons thanks to uninterrupted operation.

Redpoint and its partners continue to iterate and expand the RTLS solution, opening new possibilities for safer and more productive AGV ecosystems.
