UWB DWM1000 Positioning UWB positioning Module Ultra Wideband Indoor Positioning Module Ultra Wideband Location
Product Description
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. . UWB technology can be used to transmit signals over a very wide bandwidth. The U.S. Federal Communications Commission (FCC) stipulates that UWB technology occupies more than 500 MHz of bandwidth in the 3.1 to 10.6 GHz band. UWB is essentially a carrier-free spread-spectrum technique with shock pulses with a very low duty cycle as the information carrier. It uses direct modulation of shock pulses with very steep rise and fall times. The typical UWB directly transmits the impulse burst, which no longer has the traditional concepts of intermediate frequency and radio frequency. At this time, the transmitted signal can be regarded as a baseband signal (in terms of conventional radios) or a radio frequency signal (from the transmitted signal). Spectral component considerations). UWB technology has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, and high positioning accuracy. It is especially suitable for high-speed wireless access in dense multi-path locations such as indoors. DWM1000 module is an ultra-wideband transceiver module based on Decawave's DW1000 chip. The module inherits the antenna, RF circuit, power management, and clock circuit. Can be used for two-way positioning, time difference (TDOA) positioning system.
