Thanks to its unique precision, robustness, and reliability, Ultra-Wideband (UWB) has reemerged as a secure, fine ranging technology capable of enabling a wide range of innovative location-based user experiences and services that previous wireless technologies have been unable to effectively support. This includes a combination of device-to-device and device-to-infrastructure applications, including hands-free secure vehicle and building access, indoor localization, asset tracking, hands-free payments, seamless smart home interaction and automation, augmented reality, gaming, and a whole range of emerging smart building, smart city, industrial, and other IoT applications. While there are numerous hurdles for the technology to overcome—including standardization and interoperability, widespread chipset and device availability, greater education, and awareness, among others—ABI Research believes that UWB technology has the potential to become a ubiquitous technology embedded within smartphones and vehicles, which will act as a catalyst for large scale UWB adoption across a whole range of new IoT applications. By 2025, ABI Research anticipates there will be over 1 billion annual device shipments of UWB technology.
