What is UWB technology? Uses and how it works

UWB (Ultra-Wideband) improved functionality is updated on a series of new smartphones from Samsung and iPhone. So let’s find out with Tnhelearning.edu.vn about the definition, use and how it works!

What is UWB technology?

UWB or Ultra-Wideband is defined as a method of short-range wireless connection via radio waves similar to WiFi and Bluetooth.

In particular, UWB transmits data through ultra-wide bandwidth to tens of Ghz, helping to transmit a large amount of information, with high accuracy and high speed.

However, UWB only transmits data fast when in short range and has limitations when transmitting information in wide space.

Uses of UWB . technology

The world’s leading phone manufacturers such as Apple, Samsung, and Huawei are all involved in UWB development projects through the production of chips and antennas.

However, UWB technology was first applied on iPhone 11 and Galaxy Note 20 by Apple and Samsung.

Particularly for Apple, UWB technology has improved the Airdrop function thanks to the communication orientation. Users only need to point the iPhone towards the receiving device and transfer data quickly without having to select.

For Samsung, the adoption of UWB has added many new product functions such as remote positioning and device pairing.

How it works

UWB works like a radar that scans its surroundings, quickly detecting equipment and transmitting signals. Thanks to the advantage of using broadband, UWB promotes advantages in short distance conditions (finding phones, pairing devices, …)

UWB technology on iPhone

UWB technology was first introduced by Apple in 2019 on the iPhone 11 series to improve connection and data sharing via AirDrop.

In 2020, Apple introduced the U1 Chip , born at the same time as the iPhone 12. It can be said that the U1 chip is an important breakthrough in the development of UWB technology on iPhone. The U1 chip is used exclusively for UWB communication and is expected to be combined with Apple AirTag in the future.

UWB technology on Samsung phones

In the technology race, Samsung realizes the benefits of UWB technology. As a result, a series of Samsung phones integrated with UWB technology were born, typically the Galaxy Note 20 Ultra, the first Android phone to integrate UWB.

Thanks to that, Samsung phones can now also perform the same and even smoother pairing, data sharing, positioning functions than Iphone.

The future of UWB technology

Considered a leader in UWB technology, Samsung intends to connect phones to smarthomes through this technology. With a smartphone, you can control lights, TVs, automatic locks. At the same time, Samsung also plans to cooperate with Hyundai car company to develop features of phones with UWB technology such as opening car doors remotely, car navigation, etc.

Besides, Apple also cooperates with BMW for similar development purposes. However, the Apple ecosystem is still limited in terms of home appliances to use UWB technology.
