Qorvo’s hard-core analysis of UWB three questions

【Guide】Before Apple’s delivery, UWB (Ultra-Wideband) technology has already achieved remarkable results in military and industrial markets, but the public is at a loss as to its strength. After Apple’s AirTag was released in April 2021, UWB technology, which has been low-key and accumulating for many years, has shocked the entire consumer electronics market with its absolute strength to crush other technologies.
“The time for the outbreak of UWB technology is here!” Recently, Qorvo China Mobile Division Sales Director Jiang Xiong pointed out at the “EEVIA Ninth Annual China Electronics ICT Media Forum and 2021 Industry and Technology Outlook Seminar”. As an upstream core technology provider, Qorvo is in a leading position in UWB. It has been working on the UWB market as early as 2013. In recent years, it has been committed to providing the market with a complete set of high-performance, low-power, and highly integrated UWB chip solutions to help customers Quickly cut into the rapidly growing UWB market and achieved greater success.

Demand is blooming everywhere: what can UWB do?
Industry leader Qorvo has spared no effort in popularizing UWB technology. Delineating the application blueprint of UWB technology, looking forward to the future market prospects, and strengthening the industry’s awareness of the amazing strength of UWB technology are what Qorvo continues to do in public.
Jiang Xiong took AirTag as an example to compare the application of Bluetooth and UWB technology in finding lost objects. The Bluetooth solution can tell you that the lost object is probably in the bedroom when searching for objects; while UWB technology will point out that the lost object is on the second counter in the kitchen, making your search more accurate and more user-friendly. AirTag is also used for elderly and child safety monitoring and pet tracking.
AirTag can also realize automatic device control, such as about three meters away from the door, it can automatically recognize your identity, actively help open the door, and personalize the settings of the smart home according to your ID information; or follow your activities at home Adjust the home configuration by yourself. When you walk into the bedroom, the bedroom lights will turn on and the music will sound. When you walk into the living room, the bedroom lights will dim and the music will fade. The living room lights will gradually turn on and the music will gradually start. , Which greatly improves the comfort of smart life.
In addition, there are many application scenarios of UWB technology in life. For example, Qorvo’s OPPO Find X3 Pro mobile phone case plus Tag package, which was displayed at the scene that day, was loaded with Qorvo UWB, so that it can be accurately located by tags. The “One Finger Connect” and “One Key Connect” applications launched by Xiaomi and OPPO can easily control home appliances with one touch of a mobile phone through the UWB chip.

Through UWB tags, real-time accurate navigation in the museum can also be realized: when you approach an exhibit, the device will automatically play the corresponding explanation, and it is accurate and well-positioned, and there will be no embarrassment of wearing a crown. UWB technology can also replace NFC and realize “enhanced” payment at a certain distance: you don’t need to get close to the gate when you pass the subway gate, but you can directly complete the identification when you pass the gate, so you can pay and pass directly. Aiming at the difficulty in finding the pain points of taxis called in busy places such as airports and high-speed railway stations, UWB technology can also help quickly identify and locate, without having to look around… In addition to location-related services, UWB technology has new applications Direction-services about data transmission, which can be used for VR/AR applications, mobile phone mutual transmission, etc.

Jessica, senior sales manager of Qorvo’s ultra-wideband division, added that the current UWB data transmission applications are the collection and transmission of Internet of Things data such as temperature and humidity sensors; In terms of WiFi, UWB technology is more stable and reliable. In the future, as the data transmission rate of UWB technology is further improved, applications such as AR/VR can also transmit music, coordinates and other data in real time according to real-time displacement changes, making the game experience more realistic.
Strength Slay audience: What are the advantages of UWB?
UWB stands for Ultra Wide-Band, which is a technology designed for precise positioning and secure communication. Jiang Xiong explained that the working principle of UWB technology is that when a radio frequency signal source sends out the signal, the receiving source will receive the signal that arrives in a straight distance as soon as possible, and the flight distance of the signal can be calculated through the received timestamp.
Technical characteristics determine UWB has the following five advantages:
First of all, the accuracy is extremely high, reaching the centimeter level. There is no positioning technology on the market that is higher than this.
Second, the reliability is high, because different objects are directly transmitted and identified, and the ability to resist multipath interference is strong.
Third, real-time, extremely short delay, only milliseconds, 50 times faster than GPS response time.
Fourth, the implementation is easy, the power consumption is relatively low, and various handheld products can be easily applied.
Finally, it has high security and conforms to the IEEE 802.15.4z standard.
Compared with the broader similar technologies such as GPS, Bluetooth, WiFi, etc., UWB technology shines in the audience with its strength. As shown in the figure below, in the application scenario, UWB can be used indoors and outdoors, and GPS can only be used outdoors. In terms of accuracy, UWB can reach the centimeter level, which is much smaller than other technologies. GPS is 5 to 20 meters, and WiFi is 5 to 15 meters. In terms of coverage, UWB can cover 25 to 250 meters, Bluetooth is 15 to 100 meters, and WiFi is 50 to 150 meters. In terms of data transmission power, although UWB is not currently the main advantage of performance, it can still achieve a transmission rate of 27M bps to meet the short-term transmission needs of a small amount of data. UWB is extremely safe, enough to crush other technologies. In terms of the hottest object finding function at the moment, UWB can find 1000 objects in 10 seconds, which is very eye-catching.

In terms of physical characteristics, traditional positioning methods mainly rely on signal strength to measure, such as WiFi and Bluetooth, which can generally achieve 5 meters accuracy and 70% accuracy; some technologies use narrow-band ToF positioning to ensure 70% accuracy. In this case, only 2 meters accuracy can be achieved; while UWB technology can achieve 100% object recognition accuracy of less than 0.1 meters, which is impressive. “In terms of positioning technology,” Jiang Xiong concluded, “UWB is definitely the strongest.”
In response to the industry’s concern about the limitation of the number of UWB transceivers, Jessica took Qorvo UWB as an example to analyze and said that its working principle is to do timing allocation, such as 1 second cut into many time grids, this grid can be used for broadcasting, interactive positioning, etc., according to the allocation Do capacity restrictions. For example, in a positioning network, using TWR to measure once every second, no more than 300 tags. In addition, there is also a TDoA method, where tags only need to send uplink signals and perform calculations in the background, and they can also accept a certain collision rate, which can be measured once a second, with 1,900 tags.
