I. Introduction
With the rapid development of science and technology, wireless ranging UWB positioning technology has gradually emerged, and has shown broad application prospects in various fields. This paper will deeply discuss the principle of wireless ranging UWB positioning technology and its application scenarios in various fields to help readers better understand and apply the technology.
Second, the principle of wireless ranging UWB positioning technology
Wireless ranging UWB positioning technology is a technology that uses Ultra-Wide Band (UWB) wireless signal to realize ranging and positioning. By sending a short pulse signal, it measures the distance by using the propagation time of the signal in the air, so as to achieve accurate positioning.
UWB technology uses a large bandwidth, low power wireless pulse, which has the following key characteristics:
1. Ultra-wideband signal: The bandwidth of UWB signal is very wide, usually between several hundred megahertz and several gigahertz. This characteristic enables UWB signals to provide high resolution range measurement capabilities.
2. Low power: The power of the UWB signal is low, which can avoid interference with other wireless devices, making it more reliable in complex environments.
3. High anti-interference ability: The anti-interference ability of UWB signal is strong, and it can achieve reliable ranging and positioning in complex environments such as multi-path propagation and noise interference.
The principle of wireless UWB positioning technology can be summarized as the following steps:
1. The transmitter sends a series of UWB pulse signals.
2. The receiving end receives and demodulates these pulse signals.
3. Calculate the distance according to the delay of the received signal in time.
4. Positioning in three-dimensional space can be realized by using multiple transmitting and receiving pairs.
Third, wireless ranging UWB positioning technology application scenarios
1. Indoor positioning

For example, UWB technology can be used for outdoor billboard positioning and advertising push to achieve more accurate advertising transmission. In addition, positioning technology can also be applied to outdoor navigation systems, drone positioning and security fields, providing more convenient and safe services.
6. Health care
In the field of medical health, wireless ranging UWB positioning technology also has a wide range of application prospects. For example, within hospitals, UWB technology can be used to achieve real-time location to improve patient safety and the efficiency of medical services. In addition, in health tracking devices, UWB technology can be used for real-time positioning and distance measurement, providing more accurate data feedback.
7. Event sports
Wireless ranging UWB positioning technology can also be applied to the field of sports events. For example, UWB technology can be used to achieve real-time positioning and distance measurement of athletes' positions, so as to provide more accurate data support for referees. In addition, in terms of audience experience, UWB positioning technology can also be used to provide personalized information push and interactive experience.
Iv. Conclusion
