Ultra-Wideband
What is Ultra-Wideband and what is it used for?
Ultra-wideband UWB (also known as UWB) is a short-wave technology that supports transmission over a wide bandwidth of at least 500 MHz. UWB consumes as low as 0.5 mW / -41.3 dBm/MHz and does not interfere with other frequencies. It can only be used by devices that support UWB to detect the signal. The waves are in the range 3.1 and 10.6 GHz can be connected between computers. and other devices such as printers and screens It also transmits audio and video data, similar to Bluetooth or Wi-Fi signals, with a transmission rate of 110 kbit/s — 6.8 Mbit/s, suitable for indoor use.
In addition to sending files, UWB is also used for device discovery. A prime example is Apple’s AirTags that use UWB in combination with Bluetooth for positioning. This makes it more accurate than Bluetooth-only devices. At the same time, Samsung is developing a SmartThings Find feature that will use UWB technology in smartphones to find gadgets. as well as navigating to that gadget with an AR system, no matter how small it is Or hiding in any corner, they will definitely find it. Don’t be afraid of leaving only one earbud on one side anymore.
Ultra-Wideband in real life
use of technology Ultra-Wideband In a network related to tracking in factory logistics due to its high accuracy. This technology has started to play a role in helping to facilitate warehouses with wide areas and high shelves. And with a wide variety of products, it can be difficult to find items. This technology makes it possible to find items in large warehouses quickly and reliably. And in addition to that, the UWB that we are around in our daily life, such as wireless USB, file transfer without PC, wireless monitor, etc.
for any organization Related to manufacturing, UWB may be an important part of digital manufacturing and transportation. Now people and things don’t need to be static to save. They can also be mobile. UWB can help seamlessly digitize warehouses, stores, and process chains. stabilize internal processes and increase production efficiency Ultra-wideband is resistant to interference from other radio signals. Only specialized receivers can recognize UWB signals, so Wi-Fi or Bluetooth signals cannot interfere with UWB networks.
How it works
Similar to Bluetooth and Wi-Fi by ultra-wideband. It is a wireless wave that uses radio waves. is a high frequency but low power consumption It works within a short distance, which is different from Bluetooth and Wi-Fi that have a greater distance. The highlight of Ultra-wideband is location, because Bluetooth and Wi-Fi do not detect the location, the coordinates are only nearby. If there is a strong signal, it can receive a good signal. The UWB will measure the distance sent to the signal, which will also measure the location.
Summary of the basics of Ultra-Wideband
Able to propagate through multiple channels with little attenuation because the ultra-wideband (UWB) is a very narrow pulse signal. When several pulses arrive at the receiver overlap The passage of time or pulse interference is therefore very rare. Has the ability to transmit waves through objects as well because Ultra-wideband (UWB) combines low-frequency waves in a very wide frequency band, allowing the signal to penetrate objects. better than other systems That uses only high-frequency signals, so Ultra-wideband (UWB) works well in buildings or areas. which is blocked by a wall or other material such as a parking lot, basement.
