ShanghaiApril 29, 2026 /PRNewswire/ — On April 29, Quectel officially unveiled its next-generation automotive digital key total solution, leveraging BLE 6.0 (Bluetooth Low Energy) + UWB (Ultra-Wideband) + NFC (Near Field Communication) triple-mode fusion technology to redefine human-vehicle interaction. This brings global car owners a seamless, convenient, and intelligent multi-scenario driving experience, propelling the automotive industry into a new “keyless” smart era.
Precision Positioning: BLE 6.0 Eliminates “Waiting” and “Ping-Pong Unlocking”
Traditional BLE 5.X solutions rely on RSSI (Received Signal Strength Indicator) ranging, which is susceptible to environmental interference and signal fluctuations, causing car owners to “wait” by the vehicle and vehicles to repeatedly lock and unlock in a “ping-pong” fashion.
To address this pain point, Quectel’s new-generation digital key fully supports BLE 6.0 technology and deeply integrates the Channel Sounding feature. Combined with a proprietary fusion algorithm, it fundamentally avoids RSSI fluctuation issues, significantly enhancing ranging and positioning stability.
Whether in underground garages, complex building environments, or dense multi-vehicle areas, the solution delivers a smooth experience of “unlocking upon approach and locking upon departure”. Car owners no longer need to pull out their phones or press buttons, truly enabling seamless access and making daily driving more convenient and effortless.
Enhanced Security: UWB Ultra-Wideband Integration for Dual Upgrades in Safety and Intelligence
Precision positioning is the foundation of digital key capabilities, while security is the core bottom line. Quectel’s solution deeply integrates UWB (Ultra-Wideband) technology. Beyond secure ranging capabilities, it expands application scenarios to include broader in-vehicle child safety alerts and vehicle convenience control functions.
In-Cabin CPD (Child Presence Detection): Utilizing UWB radar’s high-precision sensing capabilities, it monitors vital signs inside the vehicle in real time, effectively preventing the risk of children or pets being left behind, ensuring travel safety.
External Foot-Kick Trunk Opening: Equipped with a proprietary UWB foot-kick sensing algorithm, it triggers the tailgate opening seamlessly, allowing users to operate easily even when carrying items, enhancing the driving experience.
Building on this, the solution achieves deep integration of BLE, UWB, and NFC technologies: BLE handles low-power wide-area wake-up, UWB provides high-precision positioning and security protection, and NFC serves as a near-field emergency solution for vehicle unlocking and starting.
The efficient synergy of these three technologies truly replaces physical keys with smartphones, and can be extended to features such as key sharing, remote authorization, and remote door unlocking for package delivery, covering diverse scenarios like family trips, business use, and temporary car borrowing.
Ecosystem Integration: Bridging Industry Standards to Build a Complete “Vehicle-Key Cloud-Phone” Service System
On the standardization front, Quectel’s digital key fully supports the three major global protocols—CCC, ICCE, and ICCOA—and is compatible with major smartphone wallets, truly enabling “one phone for all scenarios.”
What sets Quectel apart is its provision of a complete vehicle-key cloud-phone three-end solution, covering the entire chain from hardware modules and software algorithms to IoT platforms and terminal adaptation. It supports various architectures, including main anchor integration into T-BOX, cockpit controllers, or independent deployment, flexibly adapting to the electronic and electrical architecture needs of different automakers.
From hardware design and protocol integration to functional debugging and mass production delivery, Quectel provides full support, helping automakers and Tier 1 suppliers significantly shorten development cycles, reduce R&D costs, and accelerate project implementation.
Driving Future Innovation, Continuously Propelling Mobility Transformation
Looking ahead, Quectel will continue to expand the boundaries of digital key capabilities. In the sensing domain, it is advancing research on algorithms to replace ultrasonic radar with UWB radar, further expanding in-vehicle sensing capabilities. In positioning algorithms, it will continuously optimize BLE 6.0 Channel Sounding and RSSI fusion algorithms, enabling seamless switching through software updates in the future, supporting simultaneous positioning of multiple phones and multiple anchors for a more precise and stable user experience.
Additionally, Quectel will accelerate the platform-based development of its products, helping customers quickly achieve multi-configuration, multi-platform product designs. This flexibly meets the differentiated needs of high, mid, and low-end vehicle models, offering an integrated, high-performance, and highly reliable digital key solution. Together with global automakers, Quectel aims to advance automotive intelligence, bringing a seamless, safe, and convenient mobility experience to every vehicle.
From April 24 to May 3, the 2026 Beijing International Automotive Exhibition is in full swing. Quectel is showcasing its full range of in-vehicle solutions, including the new-generation digital key, intelligent cockpit, 5G automotive modules, millimeter-wave radar, and automated assembly and testing line solutions. We warmly invite friends from all sectors to visit our booth (W4 Hall, Booth 08) to experience Quectel’s comprehensive and profound automotive technology capabilities and explore new opportunities in the intelligent connected vehicle industry together!
