Description

Technical Field

[0002] With the rapid development of the Internet of Things (IoT), the demand for accurate positioning and ranging of objects in indoor and outdoor environments is growing. In many application scenarios, such as smart warehouse logistics management, industrial automation production line monitoring, smart elderly care and healthcare facilities, and personnel and asset tracking in large commercial places, it is crucial to accurately grasp the location information of the target object.

[0003] Traditional distance measurement technologies, such as positioning solutions based on Bluetooth, Wi-Fi or GPS, each have obvious limitations. Although Bluetooth technology has low power consumption, it has a short transmission distance, poor positioning accuracy in complex environments, and is susceptible to interference; conventional Wi-Fi has a relatively limited coverage range and is not stable enough when multiple devices are connected, making it difficult to meet the high-precision distance measurement requirements in large-scale deployment scenarios; GPS has severe signal attenuation in indoor environments or blocked areas, making it almost impossible to achieve effective positioning.

[0004] UWB technology has the advantages of ultra-wideband, high time resolution, strong resistance to multipath interference, etc., and can theoretically achieve high-precision ranging and positioning, with an accuracy of centimeters or even higher.
