Here are the advantages of Xiaomi Mi MIX 4 UWB technology –

As Xiaomi’s first under-screen digicam flagship, Xiaomi Mi MIX Four has attracted many shoppers’ consideration since its launch. This smartphone is the primary machine within the Xiaomi Mi MIX sequence since 2018. Though we noticed gadgets just like the Xiaomi Mi MIX Alpha and Xiaomi Mi MIX Fold, these will not be common smartphones. In addition to, the Xiaomi Mi MIX Four is the direct successor to the 2018 Xiaomi Mi MIX 3. After three years, Xiaomi Mi MIX Four not solely brings an incredible full-screen CUP, it is usually Xiaomi’s first smartphone to make use of the UWB one-finger connection expertise.

Lower than a 12 months after the expertise was launched, Xiaomi UWB has already been mass-produced on Xiaomi Mi MIX 4. In contrast with conventional Wi-Fi and Bluetooth-based positioning strategies based mostly on sign power, what are the benefits of UWB expertise? How does it obtain its new requirements? On this regard, Xiaomi formally launched a preferred science dialogue on the UWB expertise at present.

Based on the corporate, UWB expertise can carry out exact 3D positioning of the machine in area. When used with the Mi TV Grasp 77″ OLED or Mi One Finger Join, the cell phone could be pointed on the TV and the operation interface will pop up.

Extremely-Wideband (UWB) is totally different from different wi-fi applied sciences. Its working frequency vary is wider, between 6GHz – 8.5GHz. Moreover, the sign which it displays within the time area is an ultrashort pulse of solely about 2 nanoseconds.

Benefits of the ultrashort pulse

Its ultrashort pulse traits convey three benefits:

The primary is the excessive diploma of recognition, as a result of the traits are apparent, the UWB receiver can acknowledge UWB pulses from a loud sign. This permits UWB to make use of decrease transmit energy, often 30dBm decrease than Wi-Fi alerts. The sign may disguise within the “background noise” thereby inflicting nearly no interference. Subsequently, the UWB one-finger connection operate of the MIX Four is not going to have an effect on the traditional operation of radio frequencies corresponding to Wi-Fi, Bluetooth, and 5G.

Secondly, as a result of extraordinarily brief pulse, Xiaomi Mi MIX Four can rapidly decide the gap of AIoT gadgets. It does this often inside a spread of 10m and the error is just 20cm. Thus, it might successfully filter surrounding gadgets, corresponding to activating solely the closest AIoT machine to the person.

Not solely that, via the three receiving antennas on the Xiaomi Mi MIX 4, AIoT gadgets could be positioned in 3D. With this, the polar coordinates (longitudinal angle, latitude angle, and distance) could be reported for upper-layer purposes. The person may precisely decide which AIoT machine it’s pointing to. Moreover, the connection is seamless and it takes solely 20ms to finish a positioning.
