Technology Ultra Wideband (UWB) has begun to gain relevance in mobile devices and other technological sectors, thanks to its advanced connectivity features and location accuracy. Although it has been in development for decades, it has recently been adopted by companies such as Samsung, Apple and Google to improve device communication, security and automation. More and more users are asking what Samsung UWB technology is and how it improves the user experience.
With capabilities superior to Bluetooth and Wi-Fi in certain aspects, UWB is emerging as a key technology in the evolution of connected devices. In this article we will detail what it is, how it works, its current applications and the devices that already integrate it.
What is UWB and how does it work?
La ultra wide band (UWB) It is a high-frequency wireless communication protocol that operates in a spectrum ranging from 3,1 to 10,6GHzUnlike Bluetooth or Wi-Fi, which work with narrower channels, UWB uses a very wide bandwidth, making it ideal for precise distance measurements and fast data transfer.
Its operation is based on the low power radio pulse transmission over a very wide frequency range. By measuring the time it takes for the signal to travel between devices, UWB can determine the distance to within a margin of error of just 10 centimetres, which is much more accurate than Bluetooth.
Main advantages of UWB
Ultra-wideband offers a number of benefits that make it stand out from other wireless technologies:
- Greater location accuracy: Thanks to its ability to accurately measure the distances and direction of an object, UWB is ideal for tracking applications.
- Low latency: The response speed is less than 1ms, much faster than Bluetooth, making it perfect for real-time interactions.
- less interferenceBy operating over a wide frequency range and with low-power pulses, UWB generates less interference with other wireless signals.
- Increased levels of security throughout: Its signals are difficult to intercept and spoof, making it a secure solution for features such as digital keys and contactless payments.
Current applications of UWB technology
UWB adoption has grown significantly in recent years, expanding to different sectors. Some of its most relevant applications include:
Digital keys for cars
One of the most popular implementations of UWB is in the automotive. Companies like BMW, Audi and Ford have already integrated this technology into their vehicles, allowing users to unlock and start their car automatically when they approach it with their mobile phone. This represents a significant advance in user safety and convenience.
Device and object tracking
Gadgets like the Apple AirTag and the Samsung SmartTag+ use UWB to locate lost items with significantly higher accuracy than Bluetooth. This is especially useful in indoor environments where GPS is unreliable. If you are looking for alternatives to track your belongings, check out MotoTag, the alternative to AirTag for Android, which also uses this technology.
Home automation
UWB is also being used to improve interactivity in smart homes. For example, when you approach a door with a compatible mobile phone, it can automatically unlock without the need for a card or a key. These innovations are revolutionising the way we interact with our spaces.
UWB compatible devices
At the moment, not all mobile phones and devices have support for UWB, as it is a feature reserved for high-end models. Some of the devices that include this technology are:
Samsung phones with UWB
- Galaxy note20 ultra
- Galaxy S21+ and S21 Ultra
- Galaxy S22+ and S22 Ultra
- Galaxy S23+ and S23 Ultra
- Galaxy S24+ and S24 Ultra
- Galaxy Z Fold2, Z Fold3, Z Fold4 and Z Fold5
Other devices with UWB
- Apple : iPhone 11 and later, Apple Watch Series 6 and HomePod mini
- Google: Pixel 6 Pro and Pixel 7 Pro
- Xiaomi: My Mix 4

How to activate UWB on an Android mobile?
If you have a compatible device, you can easily enable UWB by following these steps:
- Accede to Settings on your mobile.
- Go to the section Connected devices.
- Choose Connection preferences.
- Look for the option Ultra Wide Band (UWB) and activate it.
On Samsung mobiles, access is found in Settings > Connections, where it can be activated directly. If you cannot find this option on your device, it is likely that your device is not compatible with this technology.
UWB technology not only offers a significant improvement in device connectivity, but also opens the door to new applications in to maximise security and your enjoyment., mobility y home automationAs more manufacturers integrate it into their devices, its presence in the market will become more common, driving the adoption of this innovative technology.
