Ultra-Wideband (UWB) Solutions
Ultra-Wideband (UWB): Precision Tracking, Redefined—Accurate, Fast, and Reliable for the Modern World.
UWB
An Ultra-Wideband (UWB) indoor positioning system is a technology used for precise location tracking within indoor environments. UWB operates by transmitting low-power radio waves across a wide frequency spectrum, typically from 3.1 GHz to 10.6 GHz, which allows for highly accurate distance and position measurements.
Ultra-Wideband (UWB) positioning works by measuring the time it takes for signals to travel between a tag and multiple fixed anchors. Using techniques like Time of Flight (ToF), Time Difference of Arrival (TDoA), and Angle of Arrival (AoA), UWB systems can determine precise distances and positions with centimeter-level accuracy. UWB is particularly effective due to its wide frequency range, short pulse duration, and low interference. It operates in real-time with high update rates, making it suitable for dynamic environments like asset tracking, robotics, and smart systems, where precise indoor positioning is crucial.
UWB Architecture
Tags
Small devices or sensors attached to an object or person that emit UWB signals.
Anchors
Fixed UWB receivers placed at known locations in the environment that receive signals from the tags.
Positioning Engine
Software that calculates the exact location of the tag based on signal data from the anchors using techniques like Time of Flight (ToF).
Gateway/Controller
Manages data flow between anchors and the positioning engine, often integrating with other systems such as monitoring dashboards.
UWB: Super-fast data transfer and pinpoint accuracy, all with minimal interference.
UWB (Ultra-Wideband) technology works by transmitting and receiving signals over a very wide frequency range, which allows for high-speed data transfer and precise location tracking. Here's a breakdown of how UWB works:
Signal Transmission
The UWB tag emits a short, low-power radio pulse over a wide frequency range, enabling precise distance measurement.
Time of Flight (ToF) Measurement
Anchors receive the UWB pulse and measure the time it took for the signal to travel from the tag to the anchor. This time is used to calculate the distance.
Triangulation/Trilateration
Multiple distance measurements from different anchors are used to locate the tag by finding the intersection points, determining the tag’s exact position.
Position Calculation
The positioning engine processes data from all anchors and calculates the tag’s coordinates, updating the position in real-time.
Real-Time Tracking
The system provides real-time position updates with low latency, making it suitable for dynamic tracking scenarios.
