UWB(Nearby Interaction) Distance Measurement
Hello, I have a question regarding the UWB (Nearby Interaction) distance measurement feature. When testing with the iPhone 14 and UWB devices (DWM3000, DW3210, NXP SR040, SR150), measurements are possible up to 5-10 meters in an indoor environment without obstacles. However, when the UWB device is inside a car, distance measurement is possible only up to about 2-3 meters from outside the car. Based on these tests, Nearby Interaction seems to be a feature designed for close-range (visually perceptible distances, around 4 meters or so). It appears that the distance range for utilizing Nearby Interaction is somewhat limited. Do you have any data on the maximum distance range for UWB distance measurement with an iPhone?
