UWB ultra-wideband technology UWB module (SKU603)
Characteristics of UWB ultra-wideband technology
1/6 Step by step reading
The realization of the system structure is relatively simple: UWB positioning system is roughly divided into position awareness layer, network transmission layer and positioning application layer.
2/6
High-speed data transmission: In theory, UWB can reach the rate of 1 Gbit/s, so it can actually reach the rate of100 mbit/s..
3/6
Low power consumption: UWB transmits data signals by sending nanosecond pulses, and only consumes a small amount of energy when transmitting narrow pulses. In short-range applications, the transmission power of UWB is usually lower than 1mw (this is also the UWB technical index requirement formulated by FCC to avoid interference with other equipment).

4/6
Low interception rate/detection rate: The transmission power spectral density of UWB system is very low, and the useful information is completely submerged in noise, so the probability of interception and detection is very low.
5/6
Strong anti-interference ability: UWB communication adopts time modulation sequence, which can resist multipath fading. Multipath fading refers to the random change of signal amplitude at the receiving point caused by the superposition of reflected wave and direct wave, while the pulse transmission time of UWB system is short, and the direct wave has been transmitted and received before the reflected wave arrives.
6/6
High precision positioning: UWB positioning precision is high. Using ultra-wideband radio communication, it is easy to integrate positioning and communication, which is difficult for conventional radio. Ultra-wideband radio has a strong penetration ability and can be used for indoor and underground high-precision positioning. UWB technology can give the relative position and the positioning accuracy can reach centimeter level.
