With the rapid development of wireless communication technology, Ultra-Wideband (UWB) technology has shown great application potential in the field of wireless ranging with its unique advantages. In particular, the emergence of low-delay communication UWB wireless ranging chip not only improves the ranging accuracy, but also greatly improves the real-time and stability of communication. In this paper, the ultra-wideband ranging accuracy of low delay communication UWB wireless ranging chip is analyzed in depth, and its technical principle, application scenario and future development trend are discussed.
I. Overview of UWB technology
UWB technology is a wireless communication technology, its signal bandwidth is usually more than 500MHz, sometimes even up to several GHz. This wideband feature enables UWB signals to transmit large amounts of data while maintaining high positioning accuracy. Compared with traditional wireless communication technology, UWB technology has the advantages of low power consumption, high bandwidth, high data transmission rate and low delay, so it has a wide application prospect in wireless ranging, positioning, communication and other fields.
Second, the technical principle of low delay communication UWB wireless ranging chip
Low delay communication UWB wireless ranging chip uses ultra-wideband signal for ranging, its basic principle is to calculate the distance by measuring the transmission Time (Time of Flight) of the signal from the transmitting end to the receiving end. Due to the extremely wide bandwidth of the UWB signal, its time resolution is very high, so it can achieve high precision ranging. At the same time, the introduction of low-delay communication technology further improves the real-time and accuracy of ranging.
Specifically, the low-delay communication UWB wireless ranging chip sends a UWB signal containing a time stamp through the transmitter, and the receiving end records the receiving time stamp after receiving the signal, and sends the time stamp back to the transmitter. The transmitter can calculate the distance between the two based on the difference in the time stamps sent and received, as well as the speed at which the signal travels. Since UWB signals propagate at close to the speed of light, this method of ranging has very high accuracy.
