Core Insights - The core viewpoint of the articles highlights the advancements and challenges of Ultra-Wideband (UWB) technology, particularly in the automotive sector, with a focus on the recent innovations by the company Gatlan, including the Dubhe CAL110X series chip and the release of a white paper on multi-millisecond UWB ranging technology [2][6]. Group 1: UWB Technology and Automotive Applications - UWB technology has emerged as a leading solution for precise ranging applications, particularly in automotive digital key systems, with expectations of a penetration rate of nearly 50% in the automotive sector by 2035 [3][5]. - Current automotive digital key experiences face challenges such as limited sensing distance (around 10 meters), poor environmental adaptability, and insufficient ranging accuracy, which affect user experience [5][6]. Group 2: Multi-Millisecond UWB Technology - Gatlan's white paper introduces multi-millisecond (MMS) UWB technology, which enhances signal transmission and reception by allowing for the accumulation of signal energy over a longer time window, improving the overall performance of UWB systems [6][8]. - The MMS UWB technology can significantly improve link budget by 10-20 dB, extending effective ranging distances and enhancing multi-path resolution in complex environments [8][9]. Group 3: Future Prospects and Standardization - Gatlan actively participates in the development of the new UWB standard IEEE 802.15.4ab, proposing various operational modes for MMS UWB, including narrowband-assisted and BLE-assisted configurations, which offer distinct advantages for commercialization [9][10]. - The BLE-assisted MMS UWB approach is expected to enhance UWB's performance while minimizing additional hardware costs, leveraging the existing BLE ecosystem widely adopted in consumer electronics [10].
