UWB (Ultra-Wideband) is a wireless communication technology (based on IEEE 802.15.4a/z) characterised by transmitting narrow pulses across a wide range of frequencies, typically with an extremely short pulse width (nanoseconds). UWB uses these narrow pulses to carry data, and its transmission and modulation differ greatly from conventional carrier-based technologies such as Wi-Fi and Bluetooth.

Wide Spectrum

Uses a broad swath of spectrum for data transmission (from hundreds of MHz up to GHz-scale bands), improving spectrum efficiency.

Narrow Pulses

Data is carried by extremely short pulses spread across frequency, giving strong interference resistance and good penetration.

High Speed

Achieves high data rates, typically at low power consumption.

High Resolution

High time and spatial resolution, suitable for a variety of ranging algorithms.
