UWB Tracking System for Runners (2026)

Introduction to Ultra-Wideband Technology

Ultra-Wideband (UWB) technology is a radio communication standard focused on providing precise location tracking. As seen in the 12Urenloop annual running race, UWB can be used to track runners in real-time. The 12Urenloop is an annual running race at the Sint-Pieters square in Ghent, where participating student association teams run a relay race for 12 hours, trying to complete as many laps as possible.

For instance, the 12Urenloop uses UWB to track the position of runners. The system consists of UWB tags attached to the runners and UWB receivers placed around the track. The UWB tags transmit signals to the receivers, which then calculate the distance between the tag and the receiver using the time of flight of the signal.

Core Concepts / How It Works

UWB works by using a wideband signal to determine the distance between a tag and a receiver. This is done by measuring the time of flight of the signal.


         import numpy as np
         
         def calculate_distance(time_of_flight):
            speed_of_light = 299792458  # meters per second
            distance = speed_of_light * time_of_flight / 2
            return distance

The time of flight is the time it takes for the signal to travel from the tag to the receiver. By measuring the time of flight, the system can calculate the distance between the tag and the receiver. This is based on the principle that the speed of light is constant, and the distance is equal to the speed multiplied by the time.

In addition to the time of flight, UWB systems can also use other methods to determine the distance, such as received signal strength indication (RSSI) and angle of arrival (AOA). However, the time of flight method is the most accurate and widely used.

Step-by-Step Implementation

Set up the UWB tags and receivers
Configure the system to measure the time of flight
Use the time of flight to calculate the distance


         import numpy as np
         
         def configure_system):
            # Set up the UWB tags and receivers
            tags = []
            receivers = []
            return tags, receivers
         
         def measure_time_of_flight(tags, receivers):
            # Configure the system to measure the time of flight
            time_of_flight = []
            for tag in tags:
               for receiver in receivers:
                  time_of_flight.append(calculate_time_of_flight(tag, receiver))
            return time_of_flight


         import numpy as np
         
         def calculate_time_of_flight(tag, receiver):
            # Measure the time of flight
            time_of_flight = np.random.rand()
            return time_of_flight

Real-World Example or Production Patterns

The Validity of an ultra-wideband local positioning system study shows that UWB can be used to track athletes in real-time.


         import numpy as np
         
         def track_athletes(tags, receivers):
            # Use the UWB system to track the athletes
            athlete_positions = []
            for tag in tags:
               for receiver in receivers:
                  distance = calculate_distance(calculate_time_of_flight(tag, receiver))
                  athlete_positions.append(distance)
            return athlete_positions

For example, in the Validity of an ultra-wideband local positioning system study, the UWB system was used to track the position of handball players. The system consisted of UWB tags attached to the players and UWB receivers placed around the court. The UWB tags transmitted signals to the receivers, which then calculated the distance between the tag and the receiver using the time of flight of the signal.

The study found that the UWB system was able to track the position of the players with an accuracy of 10-15 cm, which is comparable to other location tracking technologies such as GPS and Wi-Fi. The study also found that the UWB system was able to provide real-time data on the position of the players, which can be used to improve the performance of the team.

Best Practices & Gotchas

Use a large number of receivers to improve accuracy
Configure the system to measure the time of flight accurately
Use a robust algorithm to calculate the distance
Consider the impact of multipath interference on the system
Use a reliable communication protocol to transmit the data

It is also important to consider the environment in which the system will be used. For example, in an indoor environment, the system may be affected by multipath interference, which can cause errors in the distance calculations. In this case, the system can be configured to use a robust algorithm to calculate the distance, such as the least squares method.

In addition to the environment, it is also important to consider the type of application that the system will be used for. For example, in a sports application, the system may need to be able to track the position of multiple players in real-time, which can require a more complex system with multiple receivers and tags.
