Do you know what kind of technology is Ultra-ideband (UWB: Chogwangband) that only applies to ultra and plus during the Galaxy S23 that will be released this time?
1. What is Ultra-wideband (UWB)?
- As a technology for transmitting data in high bandwidth with very low power, it is one of the broadband wireless communication systems. UWB technology transmits radio waves in a very short time, uses a very large bandwidth, is resistant to multipath interference, and has characteristics that are insensitive to ambient noise. It uses a frequency band between 3.1 and 10.6 GHz, and the transmission speed is said to reach 480 Mbps.
2. Areas where Ultra-wideband (UWB) can be used
- Automotive safety technology: UWB technology is used to prevent vehicle collisions by measuring the distance, speed, and direction between a vehicle and an object to be recognized, and to track the location of autonomous vehicles.
- Medical field: UWB technology is used to monitor vital signs and transmit data for medical imaging.
- Positioning and Detection: UWB technology is used for indoor positioning and detection. Using this, you can accurately track the position, speed, and direction of an object.
- Industrial automation and robot control: UWB technology is used in the field of industrial automation and robot control. The robot can accurately locate moving or controlled equipment.
- Security and safety: UWB technology is used in the field of security and safety. Since quick and accurate location detection is possible, dangerous situations can be identified and dealt with quickly.
- Consumer Electronics: UWB technology is also used in consumer electronics such as smartphones and tablets. For example, tags are used to track things so that they are not lost, or to set up and manage wireless networks such as routers.
- Aerospace Industry: UWB technology is also used in the aerospace industry. For example, it is used to measure the distance of airplane parts, track the position of airplanes, etc.
3. Ultra-wideband (UWB: ultra-wideband) function that can be used in general life
- Tag-ased location tracking: UWB tags can be used to accurately track objects or pets indoors. For example, if you attach a UWB tag to your wallet, cell phone, keys, etc. and manage them in a smartphone app, you can find them right away if they are lost.
- Smartphone control: You can control other devices using UWB from your smartphone. For example, functions such as opening a car door or controlling a TV using UWB are possible.
- Virtual reality (VR) games: UWB technology can be used to track the user's location with high accuracy in VR games. This allows you to enjoy the game more realistically.
- Vehicle keys: Some cars are using UWB technology to replace vehicle keys. Through this, the car door can be opened and closed automatically, and it can be replaced in case the key is lost.
- Smart Home Systems: UWB technology is also used in smart home systems. For example, UWB can be used to set up a smart home system, or to determine whether a visitor has entered the house.
4. Relation between Ultra-wideband (UWB) and 5G
First of all, Ultra-ideband (UWB) technology and 5G technology are both emerging as important technologies in the field of wireless communication. Let's explain the relationship between the two from several perspectives.
- Frequency band: 5G technology operates in the high-requency band, and the frequency band is above 6 GHz. On the other hand, UWB technology uses a wide frequency band and uses a frequency band of 500 MHz or higher. Therefore, the two technologies have different characteristics in terms of frequency band.
- Data Transfer Rate: Both technologies support high data transfer rates. 5G supports data rates of up to 20 Gbps per second, and UWB technology supports data rates of up to 480 Mbps per second.
- Applications: 5G technology is mainly utilized in mobile communications, and is used in popular services that require large-cale data transmission, such as VR, AR, drones, and autonomous driving. On the other hand, UWB technology is used in applications such as wireless indoor location tracking, tag-based short-range communication, and communication between IoT devices.
- Complementarity: The two technologies can have a complementary relationship. For example, when data is transmitted with 5G technology, the receiving device can be accurately tracked using UWB technology. Additionally, once location information is collected with UWB technology, it can be shared with other devices via 5G networks.
In summary, UWB technology and 5G technology each have their own characteristics and applications, and can have a complementary relationship. It is likely that the two technologies will be used together in more applications in the future.
How do you guys see it?
Ultra-wideband (UWB: ultra-wideband) is a technology that feels a little far away now, but if you know it, it is already a technology that is entrenched here and there in our lives.
Perhaps in the future, it will become more deeply embedded in our lives.
