With the rapid development of wireless communication technology, Ultra-Wideband (UWB) technology has emerged in the field of centimeter-level positioning with its unique advantages. This paper will discuss the technical characteristics, application scenarios and future development trend of the mainstream cM-level positioning UWB chips in detail, in order to provide useful reference for practitioners in related fields.

I. Overview of UWB technology

UWB technology is a technology that uses narrow pulses for wireless transmission, and its signal bandwidth is usually more than 500MHz. Compared with traditional wireless communication technology, UWB technology has many advantages such as fast transmission speed, strong anti-interference ability and low power consumption. Especially in the field of positioning, UWB technology can achieve centimeter-level positioning accuracy, providing unprecedented possibilities for many application scenarios.

Second, centimeter level positioning UWB mainstream chip characteristics analysis

High precision positioning capability

The mainstream UWB chip adopts advanced signal processing algorithm and accurate time synchronization mechanism, which can achieve sub-meter or even centimeter level positioning accuracy. This is mainly due to the narrow pulse width and high time resolution of the UWB signal. By measuring the Time of Arrival (TOA) or Angle of Arrival (AOA), the chip can accurately calculate the location of the target object. This high-precision positioning capability makes UWB technology have a wide range of application prospects in indoor positioning, unmanned driving, intelligent warehousing and other fields.

Low power design

In order to meet the needs of long-term stable operation, the mainstream cm-level positioning UWB chip adopts a low-power design. Firstly, by optimizing the chip structure, unnecessary circuit components and power loss are reduced. Secondly, advanced low-power technology and energy-saving technology are adopted to reduce the power consumption of the chip in the working state. In addition, the chip also supports the sleep wake-up mechanism, that is, it enters the low-power mode in the non-working state and waits for the receiving signal or the triggering event before waking up. Together, these measures achieve high precision positioning in the low power state.

Strong anti-interference ability

UWB signal has a wide spectrum range, which can effectively avoid spectrum conflict with other wireless communication systems. In addition, the mainstream chip of cM-level positioning UWB also uses a variety of anti-interference technologies to deal with interference problems in complex environments. For example, the spread spectrum communication technology reduces the signal power density by extending the signal bandwidth, thus improving the anti-interference ability. Frequency-hopping communication avoids the constant effects of interfering signals by rapidly switching between different frequency bands. The application of these technologies enables UWB chips to maintain stable positioning performance in complex environments.

Easy integration

In order to facilitate rapid integration and application by users, cm-level positioning UWB mainstream chips usually have a smaller package size and simple interface design. The chip adopts the standard package form, which is easy to connect with other hardware devices; At the same time, the chip provides a simple interface protocol and programming interface, so that users can easily realize the communication and control with the host computer or other devices. In addition, the chip also supports a variety of operating systems and programming languages, which is convenient for users to conduct secondary development and customized applications.

Third, centimeter-level positioning UWB mainstream chip application scenarios

Indoor positioning

In large public places such as shopping malls, hospitals and airports, the traditional GPS positioning technology is difficult to achieve accurate indoor positioning because of the problems of signal occlusion and multi-path effect. The centimeter-level positioning UWB technology can make up for this deficiency and provide users with accurate indoor positioning services.
