What is UWB?

In order to conquer nature, mankind has utilized numerous methods of location from ancient times to the present. From the earliest observation of the sky, to compasses, compasses, paper maps, to today's satellite positioning, we have basically solved the problem of "where am I". To this day, human beings have a better understanding ofpositioning technologyThe requirements have gradually expanded from outdoor navigation to indoor localization. However, with the process of urbanization, indoor space is becoming denser and indoor structures are becoming more and more complex. In order not to get lost in the reinforced concrete, indoor localization technology has emerged.

The earliest indoor positioning techniques are mainlyRFID,bluetooth,Wi-Fi,ultrasound (scan),infrared rayetc. However, these technologies have their own limitations, Bluetooth and Wi-Fi technology positioning accuracy is not enough, infrared technology penetration is poor, ultrasonic technology is prone to interference. In contrast, the recent high-profileUWB technologyWith stronger anti-interference and higher positioning accuracy, it has become the most promising indoor positioning technology today.

01 UWB Overview

Ultra Wide Band (UWB) technology is a wireless carrier communication technology that transmits data by sending nanosecond non-sinusoidal narrow pulses, and calculates the return time of the radio wave to the device based on the ToF technology to measure the distance between the devices, with a very high accuracy of ranging up to centimeter level. Compared with the traditional narrowband system, the ultra-wideband system has the advantages of short transceiver time, good multipath resistance, high system security, and low overall power consumption. Therefore, UWB technology can be applied to fast and high-precision positioning tracking and navigation of indoor stationary or moving people and objects.

UWB appeared in 1960, and through the research of pioneering companies such as Harmuth, Ross and Robbins, it gained important development in radar system applications in the 1970s. In order to study the feasibility of using UWB in the civil field, since 1998, the U.S. Federal Communications Commission (FCC) began to widely consult the industry on the issue of "interference and mutual coexistence of ultra-wideband wireless devices with existing narrowband wireless communication systems". 2002, the U.S. FCC formally adopted the 3.1GHz-10.6GHz band as the frequency band for indoor wireless communications. 10.6GHz band for indoor communication, marking the beginning of UWB for civil wireless communication. In the following years, the radio administrations of Japan, Singapore and the European Union issued similar decrees. China started the preparation of UWB spectrum planning in 2006, and in 2008, China's UWB spectrum planning was formally released, including RF specifications of UWB signals, restrictions on application sites, and equipment approvals.

02 Technical characteristics

UWB technology is now based on the latest IEEE 802.15.4a/z standard, which has been optimized for microlocation and secure communications. As a high-precision positioning technology, UWB can pinpoint people and objects to within a few centimeters, making it nearly 100 times more accurate than current low-power Bluetooth (BLE) and Wi-Fi implementations, and its superior high-precision performance is perfectly suited for indoor positioning applications.

1. High positioning accuracy. Under line-of-sight conditions, UWB positioning accuracy can reach within 10cm, much higher than other wireless positioning technologies. It is suitable for many application scenarios, such as the management of AGV carts, trajectory monitoring of personnel in judicial prisons, and real-time monitoring of raw materials in intelligent manufacturing.

2. Good stability. First of all, UWB technology has high immunity to various types of interference (including multipath), and the anti-interference ability of its emitted pulse wave is stronger than that of continuous electromagnetic wave. Secondly, UWB works in the frequency band of 3GHz-10GHz, compared with the wireless positioning technology in the 2.4G band, there are fewer interference signals from the outside world.

UWB utilizes IEEE-defined limiting techniques to provide a degree of security that makes it an extremely secure format.

4, low latency. UWB's communication transceiver speed can be as high as 1000 times per second, readings are 50 times faster than satellite navigation, and can be applied to real-time positioning/tracking of any object.

5, Economical and practical, UWB chip using mainstream process technology, can be optimized for low-power application scenarios.

Based on the above characteristics, UWB positioning technology in consumer applications also continue to develop, there have been some manufacturers have developed such as positioning tags, intelligent follow luggage and other consumer products, and in the future, if the UWB positioning technology can be integrated into the cell phone inside, will stimulate the rapid outbreak of consumer applications.

03 Development prospects

In the Internet of Things industry, indoor location information will be one of the most important information attributes of people or things.UWB will help upgrade the smart home application scenarios with its characteristics.With the maturity of the smart home ecology, the market scale of UWB consumer-level applications is huge. According to relevant information, China's UWB indoor positioning market is expected to reach $2.21 billion in 2022, accounting for 18.0% of the global market size, while China's enterprise-level UWB indoor positioning market will reach $12.15 billion, with a CAGR of 85.6% from 2017.

At the commercial level, giants and startups at home and abroad have made a lot of attempts to promote indoor positioning technology to the ground, and the indoor location service industry chain is taking shape.

At the government level, China's State Council, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology have issued a number of guiding policies to vigorously promote the development of indoor positioning systems. For example, the country's 13th Five-Year Plan has formulated standards for navigation and location services, including seamless indoor and outdoor navigation, indoor and outdoor multi-mode cooperative positioning, indoor multi-dimensional location information, location intelligent sensing, and unmanned map services.

The strong involvement of industry giants and government organizations in indoor positioning and location services will promote the rapid recognition of indoor positioning by users and accelerate the maturation of the indoor location service ecosystem and the landing of applications. It can be seen that in the next few years, China and even the global indoor positioning service applications will usher in rapid growth.
