The BLE Legend BLE-enabled digital car key systems that realize features of passive keyless entry (PKE) or even passive entry and passive start (PEPS) have reaped wide popularity among car makers, as that single ECU gives their new models an intelligent face lift. However, existing BLE systems are inherently vulnerable to relay attacks, making PKE/PEPS exposed to thefts and hijacks. A TikTok short video showing how two thieves stole a Bentley with some simple relay attack tool in thirty seconds went viral recently. UWB Came to Rescue Such incidents aroused worries among motorists and car buyers, and also prompted carmakers to rethink the baseline technology of the existing digital car key system. The Ultra-Wide-Band (UWB) technology came into their scope of view. Due to its features of much higher locating precision and ultra-high frequency pulse radio that is immune to relay attacks, it has become a major part of the global standard for digital car keys issued by the Car Connectivity Consortium – CCC3.0. Other two-car connectivity standard bodies – ICCE and ICCOA also recognized it by including it as a major enabling technology. From 2022 on, car makers such as BMW, BYD, Geely and NIO began to ship UWB-enabled car models for premium car owners. Such quick adoption is not only built upon the technology's supremacy but also over a belief that the economy of scale will be realized soon. The source in the technical circle said Qualcomm will release a UWB-embedded smartphone SoC in early 2024. That will prompt major phone makers to produce UWB smartphones to join the league of Apple iPhone, making the UWB installation base terminal wise dramatically increase. And people believe in the near future, the UWB will become a ubiquitous wireless communication technology in daily life. The foreseeable huge terminal user base boosted undoubtedly car makers’ confidence in the technology. Why UWB for Digital Keys? Now, let us look at some major technical properties of UWB to get a deeper understanding of why we need UWB for next-generation digital keys of future vehicles. Precise Location The UWB communication involves the information exchange between the UWB keyfob (also known as Tag) and the UWB Anchor installed in the car. The Time-of-Flight (ToF) measurement uses specific fields in the UWB messages as timestamps to calculate precise distance. UWB technology utilizes very short pulses (lasting only nanoseconds) of low-power signals with a wide bandwidth (> 500 MHz). UWB’s wide bandwidth and short pulses bring little interference and few multi-path effects compared to narrowband signals. In some ways, UWB can effectively measure range with an accuracy of up to 10cm. Enhanced Security Today's technologies relying on signal strength to evaluate distance are vulnerable to relay attacks. Car thieves intercept and amplify the signal strength of a valid key and deceive the receiver into believing that the digital key is nearby. Then, these attacks cause the lock...

The emergence of the bike-sharing model in 2017 instantly disrupted traditional commuting of urban people in China. However, while it brings convenience to our life, it also incurs some disadvantages. Random stop and go not only brings much inconvenience to other residents, but also incurs great trouble to city managers and shared bicycle operators. To further improve the order of shared bicycle parking, city managers were prompted to regulate parking behavior. Advent of Bluetooth electronic fence simply address the issue. With its features of broadcasting, transmission and positioning, the Bluetooth electronic fence technology can demarcate boundaries for parking and count bikes in those specified areas. What is a Bluetooth Electronic Fence Bluetooth electronic fence refers to a virtual geographic demarcation system that enables operators or city managers to lay out and regulate certain areas for shared bicycles to park. The solution is realized by placing Bluetooth beacon devices in those specified areas. Cyclists riding shared bikes can locate the specified parking spaces with help of their mobile devices. The beacon devices can detect shared bikes within a specified radius. If the bike were parked outside the virtually fenced area or were ridden out of it, the system will send notifications, so that the manager can understand the dynamics of the relevant bikes in time, and take corresponding measures to deal with it. Public electronic fences realize data interaction with Bluetooth, its positioning accuracy reaches sub-meter level making it capable of accurately addressing cases of each bike in the herd. They can also accommodate shared-bikes of different operators. Featuring bike wireless identifying, fine line geo-demarcation and ultra-long autonomy, Bluetooth electronic fences for shared bikes can provide reliable service of bike access sensing and parking management with little deployment effort. Comparing electronic fence technologies There are three major implementation technologies for electronic fences: Electronic fences based on Global Positioning Systems (GPS). Use the Bluetooth read-write device embedded in the bicycle lock to detect the signals of the Bluetooth tag installed in the parking sites. Use the user's mobile phone Bluetooth to read the Bluetooth electronic tag of the parking site and the shared bike. The first and second technologies rely on satellite positioning technology and the Bluetooth device in the bike lock respectively, which are relatively invisible. The third technology is more convenient for installation, and is suitable for mass deployment. At the same time, the Bluetooth electronic fence of latter technology can also count the number of bikes parked within the fence, and facilitate sharing data between the urban management authority and sharing bicycle operators. Thus overall load balancing and scheduling can be achieved. For now, such electronic fence is available for all sharing bicycles featuring Bluetoot...
