Igeekphone December 9 news, the blogger digital chat station suggested that Xiaomi launched a digital series of small iteration of the product Xiaomi 15S Pro in the first half of next year, the difference between it and Xiaomi 15 Pro is mainly the chip change, flash micro convex and equipped with UWB technology.
Data show that the Xiaomi MIX 4, which debuted in 2021, was the first to be equipped with UWB technology, and the English full name of UWB is “Ultra Wide Band”, that is, “ultra-broadband communication”.
Ultra-wideband technology comes from pulse communication technology, which is called “ultra-wideband” because the bandwidth used is more than 500MHz, and because the time of its pulse is very short, it can send a large amount of data in a short time, while the power is not too high.
It is reported that UWB and Bluetooth, WiFi are wireless communication technology, but UWB has a number of technical advantages, one is its bandwidth is large, high frequency (3.1GHz-10.6GHz), making anti-interference ability is strong, will not be WiFi, Bluetooth, base station and other communication signals confused; Second, its accuracy is high, because the pulse signal is nanosecond level, the accuracy can be controlled at the centimeter level when positioning; Third, UWB does not need to work in real time, and the power consumption is much lower than WiFi and cellular networks.
In specific applications, when we pick up the mobile phone and point it at the smart device, the corresponding control interface will automatically pop up. For example, when the mobile phone points to the fan, the fan can be directly controlled; when the mobile phone turns to the TV, the control card will automatically switch to the interface controlling the TV; in addition, the screen of the mobile phone can be directly projected to the TV, laptop and other devices. Or play music to the speaker.
It is worth mentioning that the iPhone 11 model released in 2019 is also equipped with UWB technology, and the official claim that the machine has spatial awareness, in simple terms, it can sense the orientation, such as when using airdrop, it will identify the distance of the delivery device, the closer the priority.
For Xiaomi, UWB can allow the mobile phone to turn into a car key, the owner of the car in the parking lot to quickly locate their vehicle, Bluetooth and NFC are essentially near field communication, do not have the ability to accurately, they can help you unlock the vehicle, but it is difficult to accurately help you find the vehicle.
