Learn How UWB Moves Communications Forward​

The ultra-wideband (UWB) short-range communication protocol enables advanced location-based communication features like secure hands-free access, indoor navigation, contactless payments, credential sharing and item tracking.

Unique to UWB is time-of-flight (ToF) measurement that accurately measures the time it takes for a signal to travel between devices, making it more difficult for an external attacker to access or manipulate UWB communications. UWB can measure distances with an accuracy of down to 10~30 cm, far better than the ranges of WiFi (2~3 m) and Bluetooth (1~5 m).

Frequency control plays a big part in this precision data and timing alignment. For instance, a stable oscillator provides a reliable and accurate clock signal, which ensures that the UWB pulses maintain their desired shape and spectrum.

This new white paper outlines both the UWB protocol as well as the frequency control considerations needed when developing these device-to-device networks to optimize wireless communication. 

Specific benefits of UWB detailed in the paper include:

  • Wireless speed
  • Accuracy
  • Security
  • Power efficiency
