When two devices directly connect and communicate using UWB, we can measure how long it takes for the radio wave pulses to travel between them, which is commonly referred to as Time-of-Flight (ToF).

[Greg] is promising a new book on practical approaches to developing and using small radar devices titled “Small ... phase array and also UWB impulse radar. It sounds like an interesting book ...

While Samsung supports UWB through Galaxy SmartTags, Google has so far not offered anything similar on Find My Device. Google’s been working on changing that, though, and the latest Find My ...

There are several exciting Apple hardware announcements that we expect to see in 2025. The year is flying by quickly, but ...
