Calterah’s Dubhe, the world’s first IEEE 802.15.4ab-compliant ultra-wideband (UWB) SoC series with 2T4R radar capability, addresses the pain points in existing digital key solutions and offers high-precision, secure ranging and positioning. Built on Calterah’s Dubhe UWB SoCs, digital keys can achieve improved secure ranging, more accurate long-distance positioning, stronger non-line-of-sight (NLoS) penetration, and greater power efficiency. With its radar sensing capability, the chips also support reuse for multiple radar functions, reducing system costs while enabling safer and smarter automotive mobility.
