With the rapid development of the Internet of Things, autonomous driving, intelligent warehousing and other fields, high-precision positioning technology has become the key to promote progress in these fields. Among them, Ultra-Wideband (UWB) technology has been widely concerned by the industry for its centimeter-level positioning accuracy and high-speed data transmission capability. In recent years, domestic cm-level positioning UWB chips have continued to make breakthroughs, showing strong market competitiveness, and injected new vitality into the development of related industries in China.

I. Overview of UWB technology and development status of domestic chips

UWB technology is a wireless carrier communication technology, which uses non-sinusoidal narrow pulse from nanosecond to microsecond to transmit data. It has the characteristics of wide band width, fast transmission speed, low power consumption and strong anti-interference ability. In terms of positioning, UWB technology achieves high-precision positioning by measuring the signal transmission time difference (TDOA) or the Angle of arrival (AOA). Compared with traditional positioning technologies such as GPS and Wi-Fi, UWB has higher positioning accuracy and is not affected by environmental factors, which can be applied to the positioning requirements of complex indoor environments.

At present, a number of domestic enterprises and research institutions have invested in the development and production of UWB chips. These domestic chips continue to improve in performance, and gradually approach or even catch up with the international advanced level. At the same time, domestic chips also have obvious advantages in cost, making it possible for UWB technology to be applied in more fields.
