Following the iPhone 11 Pro series, the Galaxy Note 20 Ultra, released last night, became the industry’s second flagship phone with ultra-broadband technology. With Google’s latest Nearby Share feature, users can share files with other Galaxy devices equipped with UWB technology.

Samsung also announced that UWB-based technology also helps you find things more precisely with AR technology, turning a Galaxy phone into a “digital key” to open your door. Samsung has partnered with ASSA ABLOY, the industry’s leading supplier of access control products, and will be able to unlock it in the future with a Galaxy phone instead of a key.

Ultra Wide Broadband (Ultra Wide Band, UWB) technology is a wireless carrier communication technology that does not use sine carriers, but transmits data using nanosecond-level non-sine wave narrow pulses, so it occupies a wide spectrum.

UWB technology has the advantages of low system complexity, low transmission signal power spectrum density, insensitivity to channel decline, low interceptability and high positioning accuracy, especially for high-speed wireless access in dense multi-path locations such as indoors.
