Ultra Wide Band (UWB) technology is a wireless carrier communication technology that does not use a sinusoidal carrier, but instead utilizes narrow pulses of non-sinusoidal waves in the nanosecond range to transmit data, and therefore occupies a wide spectral range.
UWB technology has the advantages of low system complexity, low transmit signal power spectral density, insensitivity to channel fading, low interception capability, high positioning accuracy, etc. It is especially suitable for high-speed wireless access in indoor and other dense multipath places.
