How UWB Ranging Works: TOF, TDOA, and Angle of Arrival Explained

Explore how Ultra-Wideband (UWB) technology enables precise distance and direction measurement using advanced ranging techniques. In this short explainer, we break down how UWB calculates time-of-flight (TOF), time-difference-of-arrival (TDOA), and angle-of-arrival (AoA) to deliver centimeter-level accuracy for indoor positioning, navigation, and smart device interaction. 📘 Learn More Explore NXP’s UWB Portfolio: https://www.nxp.com/uwb 📚 Related Resources NXP UWB Technology Overview: https://www.nxp.com/uwb Get help from our NXP Community: https://community.nxp.com 🎯 Video Highlights • What single-sided and double-sided two-way ranging are • How time-of-flight (TOF) is used to calculate distance • How TDOA enables indoor location with synchronized anchors • How angle-of-arrival (AoA) is calculated using phase differences • When to use each technique and their trade-offs ⏱️ Video Chapters 00:00 – Introduction to UWB Ranging 00:20 – Single-Sided Two-Way Ranging (SS-TWR) 00:50 – Double-Sided Two-Way Ranging (DS-TWR) 01:30 – Time-Difference-of-Arrival (TDOA) 02:10 – Angle-of-Arrival (AoA) and Phase Difference 02:40 – Antenna Spacing and Channel Considerations 📺 Subscribe for More Subscribe to NXP:    / @nxpdeveloperzone   🎥 More Videos All NXP Videos:    / @nxpdeveloperzone   🌐 Connect with NXP Facebook:   / nxpsemi   LinkedIn:   / nxp-semiconductors   X (Twitter): https://x.com/nxp Website: https://www.nxp.com/?cid=soc__tac2041...
