Xiaomi 15S Pro has three complete certificates: just waiting for the official announcement

Xiaomi 15S Pro has three complete certificates and its model number is 25042PN24C, so it can be officially announced. The phone will be launched in April at the earliest.

According to blogger Digital Chat Station, Xiaomi 15S Pro mainly has a “chip replacement” and also supports UWB, and can be linked with its own Xiaomi SU7 series cars.

It is understood that the full English name of UWB is “Ultra Wide Band”, which means “ultra-wideband communication”. The reason why it is called “ultra-wideband” is that the bandwidth used is above 500MHz. At the same time, because its pulse time is very short, a large amount of data can be sent in a short time, and the power will not be too high.

UWB, Bluetooth and WiFi are all wireless communication technologies, but UWB has many technical advantages. First, it has a large bandwidth and a high frequency (3.1GHz-10.6GHz), which makes it highly anti-interference and will not be confused by other communication signals such as WiFi, Bluetooth, and base stations. Second, it has high accuracy, because the pulse signal is at the nanosecond level, and the accuracy can be controlled at the centimeter level during positioning. Third, UWB does not need to work in real time, and its power consumption is much lower than that of WiFi and cellular networks.

For Xiaomi, UWB can transform the mobile phone into a car key, allowing car owners to quickly locate their vehicles in the parking lot. Bluetooth and NFC are essentially near-field communications and do not have precise capabilities. They can help you unlock the vehicle, but it is difficult to help you find the vehicle accurately.

In addition, Xiaomi 15S Pro will use a 2K full-depth four-micro-curved screen, a rear Leica triple-camera, and will be pre-installed with the Surge OS 2 system.
