蓝牙AOA高精度定位技术白皮书

2019 年初,蓝牙技术联盟宣布蓝牙 5.1 引入了新的“寻向”功能,这个功能 可检测蓝牙信号的方向,将大幅提高蓝牙定位的精确度,提供更好的位置服务, 结束了以往通过 RSSI 信号强度的方式做低精度指纹定位的历史,为蓝牙技术解 决物联网精确定位与导航问题奠定了基础。

依据被定位终端的上下行模式的不同,蓝牙高精度定位可以分为两种技术原 理,分别是:AoA 到达角度法(Angle of Arrival)和 AoD 出发角度法(Angle of Departure)。
大家熟悉的按需的世界已经成为过去时。按一下按钮,即可得到服务,这样的模式虽然不错,但我们都知道它正在成为历史。我们希望创造未来,而未来与预知变化和自动化密切相关。我希望所处的环境能够预知我接下来的操作,我希望环境能够自动提供最初预测的服务。与此同时,一场极速且深刻的变革正在进行,涉及我们的生活、消费和移动的方方面面。我们希望创造未来,而未来与预知变化和自动化密切相关。我希望所处的环境能够预知我接下来的操作,我希望环境能够自动提供最初预测的服务。与此同时,一场极速且深刻的变革正在进行,涉及我们的生活、消费和移动的方方面面。在一个能够预知变化并实现自动化的世界中,我想确保自己的隐私范围,还要保证数据安全性。我说过世界正在朝自动化发展,所以我同样要确定所有自动化技术的功能安全性。
无钥匙进入系统几乎已成为汽车的标配。不过在提供省去物理钥匙的便捷性之外,消费者更期待智能进入系统能够实现更多功能,覆盖更丰富的应用场景,并且解决安全隐患。顺应这一趋势,大陆集团将超宽带(UWB)技术融入其智能进入系统。
Indoor positioning is, in many ways, an inside version of the satellite-navigation apps we rely on for outdoor navigation, but with an added twist – it can also be used to help locate people and things.
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.

Ultra-Wideband (UWB) technology has the unique ability to deliver unprecedented accuracy and security when measuring the distance to a target or determining position, transforming the way people experience connectivity. Computerworld recently said that “One way to think of it is as a radar that can continuously scan an entire room and precisely lock on to an object like a laser beam to discover its location and communicate data.”
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.

UWB Use Cases

Have you ever dreamed of having your front door automatically unlock as you approach? Or wished your house would anticipate your needs and set-up the lights and your TV as you sit on your sofa? Or maybe you want to precisely locate critical health monitoring equipment as you join your shift at the hospital. We are excited to let you know that UWB’s unique fine-ranging capabilities are making these previously impossible applications a reality!

Compelling new experiences benefiting users, combined with the development of an open and interoperable ecosystem, is driving rapid and widespread adoption of UWB across multiple markets and applications.

The (r)evolution has started and UWB will soon be at the heart of our daily lives!
