FAQ
Q: What is the accuracy of the UWB ranging?
A: The NCJ29Dx provides centimeter-level ranging accuracy under optimal conditions. Actual accuracy depends on antenna design, environmental conditions, and ranging algorithm implementation.
Q: How does UWB compare to Bluetooth for precise positioning?
A: UWB provides much higher precision (centimeter-level) compared to Bluetooth (meter-level) for positioning. UWB also has lower latency and better security features for access applications.
Q: What is the typical range for UWB applications?
A: The typical range for UWB applications is up to 10 meters, though this can vary based on antenna design, power settings, and environmental conditions.
Q: How does the security of UWB prevent relay attacks?
A: UWB uses time-of-flight measurements to determine distance, making it extremely difficult to perform relay attacks. The short time-of-flight measurement and secure ranging protocols ensure that only devices within the expected range can authenticate.
