UWB technology is a wireless carrier communication technology that uses a frequency bandwidth above 1 GHz. It does not use a sinusoidal carrier, but uses nanosecond-level non-sine wave narrow pulses to transmit data, so it occupies a large spectrum range. Although it uses wireless communication, its data transmission rate can reach hundreds of megabits per second or more. Compliant with IEEE 802.15. 4-2011 UWB Supports 4 RF bands from 3.5 GHz to 6.5 GHz
