   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-sinusoidal narrow pulses to transmit data. Therefore, it occupies a large spectrum. Although wireless communication is used, its data transmission rate can reach hundreds of megabits per second. . Using UWB technology can transmit signals over a very wide bandwidth.

  BU01 is an ultra-wideband (UWB) transceiver module based on Decawave's DW1000 design.
  BU01 integrates antenna, RF circuit, power management and clock circuit.
  BU01 can be used in two-way ranging or TDOA positioning systems, with positioning accuracy up to 10 cm and supporting data rates up to 6.8 Mbps.


  • Simple integration, no RF design required
  • Using RTLS infrastructure to expand the communication range
