This paper will conduct an in-depth analysis of the high-precision positioning UWB tag chip, from the technical principle, application scenarios to future development trends and other aspects of a comprehensive discussion.

I. Overview of UWB technology

Ultra-wideband (UWB) technology is a wireless communication technology that transmits data using non-sine-wave narrow pulses from nanoseconds to microseconds. This technology has a wide spectrum range and high bandwidth, and can complete the transmission of a large amount of data in a short time, so as to achieve high-speed communication and accurate positioning. Compared with traditional wireless communication technology, UWB technology has higher positioning accuracy and lower power consumption, and has become one of the important technologies in the era of Internet of Things.

The basic principle of UWB technology is to measure the propagation time of the signal in space by sending and receiving a short time pulse signal, so as to calculate the distance between the sending end and the receiving end. Because of the wide band width of UWB signal, its multi-path effect and attenuation are small, so that the positioning accuracy is greatly improved.

Second, the technical principle of high-precision positioning UWB tag chip

High precision positioning UWB tag chip is the core component of UWB technology, its technical principle is mainly based on pulse signal transmission and reception. Specifically, the UWB tag chip emits a non-sine-wave narrow pulse signal in the nanosecond to microsecond scale, which travels through space and is then captured by the receiver. By measuring the time the signal travels from transmission to reception, combined with the known speed of electromagnetic wave propagation, we can calculate the distance between the tag and the receiver.

In order to achieve high-precision positioning, the UWB tag chip also uses a variety of advanced technical means. For example, it can receive signals from multiple receivers at the same time, using algorithms such as triangulation or small squares to determine the specific location of the label in two or three dimensions. In addition, the UWB tag chip also has a strong anti-interference ability, and can work stably in a complex electromagnetic environment.

The characteristics of high-precision positioning UWB tag chip are mainly reflected in the following aspects:

High precision: Due to the wide band width of the UWB signal and the propagation speed close to the speed of light, centimeter-level positioning accuracy can be achieved to meet the needs of various high-precision application scenarios.

Low power consumption: High precision positioning UWB tag chip adopts advanced low power design, which can reduce power consumption and extend service life while ensuring positioning accuracy.
