Everything you need
to know about UWB wireless technology

UWB stands for Ultra-Wideband which is predicted to become as common as Bluetooth.

UWB will become ubiquitous, make surroundings context aware and increase wireless interaction between human beings and objects in our everyday lives.

Today UWB is used in everything from laptops, mobile phones, baby calls, sleep monitors and in lights and air-conditioning. Soon you will find the technology in your car to ensure that your kid or dog is not accidentally left behind and in prison cells UWB can confirm that the inmate is breathing and healthy. Smart speakers will be able to direct the sound to where people are in the room, and your laptop can even tell you if you are about to become ill.

Follow the development of UWB and be amazed by the possibilities.

NOVELDA tech stories

UWB is used to sense and locate people and objects, and to transmit data

Like Bluetooth and Wi-Fi, UWB is a low-power, short-range, wireless technology that operates through radio waves.

It is used to sense objects and people, to transmit data with short latency and to give information about the location of an object or a person. UWB technology is defined in the frequency range of the radio spectrum from 3.1 to 10.6 GHz and has a wide channel bandwidth of 500 MHz or higher.

Power spectral density

Unique advantages

The short pulses and fine time resolution available in UWB systems give some unique advantages and opportunities related to the ability to determine distance based on time of flight.

In communication systems, the fact that the pulses travel at the speed of light, which cannot be exceeded, opens the possibility of providing cryptographically secure range limitation by exchanging pulse sequences that are only sent once.

This means that for instance payment transactions and car access systems can be protected against attacks.

The UWB sensor can decide how far it wants to see, and the zone can be configured firmly. As a result, you can select good sensitivity inside the zone while rejecting large objects outside the zone. Even an elephant walking close to the zone will not be detected.

Short pulses and fine resolution in time enables a system to evaluate the response from the closest objects before the response from objects further out has reached the receiver.

UWB based distance measurement is much less prone to interference from multipath signals than for instance Bluetooth based systems, and thus UWB has advantages compared to Bluetooth in indoor environments.

Precise distance measurement can be a benefit in applications offering functionality based on location. This can take place in two ways, either by a radar that measures the distance to a passive target, or by two UWB communication radios measuring the distance between each other.

This feature of the technology can be used for indoor navigation and in asset tracking.

Many dozens of UWB devices can operate in the same small physical space at the same time.

The sequence of positive and negative pulses is chosen so that the intended recipient can easily filter it out of the noise while not being disturbed by transmissions of other sequences or other parts of the same sequence. This is due to the cross correlation and auto correlation properties of the chosen sequences.

Since each pulse is very short it will only look like slightly increased background noise to other users of the same spectrum. The pulses are bi-phase coded, meaning that they are either in phase or 180 degrees out of phase with other pulses from the same transmitter.
