What are the technical characteristics of UWB Ultra-wideband?

UWB Ultra-wideband has the advantages of insensitivity to channel fading, low transmit signal power spectral density, low possibility of interception, low system complexity, centimeter-level positioning accuracy, etc.

1. Simple system structure

The UWB Ultra-wideband transmitter is directly pulsed with a small microstrip antenna. Since UWB does not require modulation and demodulation of the carrier signal, it does not require complex devices such as mixers, filters, RF/IF converters, and local oscillators, and is easier to integrate into CMOS circuits.

2. High-speed Ultra-wideband data transmission

Theoretically, a pulse of width 0 has infinite bandwidth, so for a pulse signal to be emitted and have sufficient bandwidth, it must have a steep enough rising/falling edge and a narrow enough width.

The pulse width of UWB Ultra-wideband is used in military radar systems at the ps level at the shortest; in civilian use, it is generally at the ns level. ns is one billionth of 1s, which means that if a pulse represents one digit, then UWB has the ability to transmit one billion digits in 1s, i.e., a rate of 1Gbit/s; if the pulse width is reduced to 0.1ns, the rate can be up to 1Gbit/s.

3. Low power consumption

Since no carrier is used, only a small amount of energy is consumed when transmitting narrow pulses, thus saving a lot of energy consumption when transmitting continuous carriers.

This feature also enables UWB Ultra-wideband to increase bandwidth without increasing power consumption by reducing the pulse width, which breaks the law that power consumption and bandwidth are directly proportional to each other in the past transmission technology.

The power of UWB Ultra-wideband devices for civilian use is generally about 1/100th of the power required for traditional cell phones and about 1/20th of the power required for Bluetooth devices. UWB radios for military use also consume very little power.

Therefore, UWB devices have great superiority over traditional wireless devices in terms of battery life and electromagnetic radiation.

4. High security

Because UWB Ultra-wideband signals generally disperse the signal energy in a very wide range of frequency bands, for general communication systems, UWB signals are equivalent to white noise signals, and in most cases, the power spectral density of UWB signals is lower than the natural electronic noise, and it is very difficult to detect the pulse signal from the electronic noise.

After the pseudo-randomization of pulse parameters by coding, the detection of pulses will be even more difficult.

5. Multipath discrimination ability

As the ultra-wideband radio is transmitted by a very short duration of the single-cycle pulse and the duty cycle is very low, the multipath signal is separable in time.

Therefore, it is suitable for high-speed transmission in complex environments such as indoors. A large number of experiments show that the multipath fading of conventional radio signals up to 10-30dB deep multipath environment, the fading of ultra-wideband radio signals up to less than 5dB.

6. Precise positioning

Ultra-wideband radio has a strong penetrating ability, and can be accurately located indoors and underground, while the GPS positioning system can only work within the visual range of GPS positioning satellites;

GPS to provide absolute geographic location is different, an ultra-short pulse locator can give the relative position, and its positioning accuracy can reach the centimeter level.

7. Strong anti-interference performance (electromagnetic compatibility), low BER

The bandwidth of UWB is equivalent to 1000 TV channels or 30,000 FM broadcast channels, so the power density per unit bandwidth is quite low.

The power density is even lower than the general noise level (e.g., lower than the radiation of a laptop computer). Therefore, the impact of UWB Ultra-wideband on other devices is minimal.
