UWB技术的工作原理探讨

超宽带技术 (UWB) 是最佳定位跟踪技术,您应该使用这项技术。我们可以说 UWB 是当今最好、最先进的定位技术,但证据呢?要回答这个问题,我们需要透过现象看本质。 本章探讨了 UWB 技术的内部工作原理,并概述了 UWB 和窄带定位方法之间的差异。此外,本章还说明了如何针对不同的应用或用例场景选择最佳的系统架构。

随着小米MIX4的发布,以及之前的OPPO一键联手机壳套装,国产手机也开始正式拥抱UWB技术,从原本的技术展示,转为真正走向消费市场。

实际上,相比于目前UWB技术所实现的找钥匙、连连看功能,UWB的目标是能够成为像蓝牙、Wi-Fi这样在终端上不可或缺的标配技术,衍生出的功能也会让使用者越来越离不开,甚至有的厂商还对这一技术的应用打起了“歪主意”。

像任何其他新兴技术一样,有关UWB的误解几乎和事实一样很快登上了新闻头条,有些甚至长期保留在我们的记忆中。随着这项技术变得越来越大众化,我们邀请了几位UWB生态系统参与者解读对于UWB现状和未来的误解。让我们来解开关于UWB的四个误解。

UWB技术将带来怎样的全新体验?

超宽带(UWB)技术是无线技术的下一个重要领域

Qorvo, a leading provider of innovative RF solutions that connect the world, has acquired Paris-based 7Hugs Labs S.A.S., a leading software provider for ultra-wideband (UWB) applications. The acquisition of 7Hugs Labs helps strengthen Qorvo’s UWB product offering for smartphones and other devices that increase the accuracy of a host of new location and communication services.

SECURE ULTRA-WIDEBAND (UWB)POSITIONING AND RANGING OPTIMIZED FOR IoT USE CASES
In this paper we present an overview on the development and standardization of ultra-wideband systems, technical aspects of the IEEE 802.15.4 standard, and improvements made by the 802.15.4z amendment. We also explain the basic workings of a physical access system, the desired seamless access experience and how ultra-wideband technology can enable it. In addition, we briefly compare ultra-wideband to facial recognition access systems. We conclude by mentioning how ultra-wideband technology may extend to other related applications.
DECADES-OLD ULTRA-WIDEBAND TECHNOLOGY IS ENJOYING A RENAISSANCE IN SECURE ACCESS AND BEYOND
Like Bluetooth and Wi-Fi, ultra-wideband (UWB) is a wireless technology that uses radio waves for communications. By operating at a very high frequency and using a wide spectrum, UWB outperforms other wireless technologies in terms of accuracy, robustness in wireless connectivity, and security.
