Xiaomi released the “One Finger Link” UWB (Ultra-Wideband, ultra-wideband) technology, which allows the mobile phone to directly enter the App control interface when pointing to each smart home device, improving the user experience. Xiaomi emphasized that in the future, Xiaomi will sell smart services, not just mobile phones or separate smart devices.

UWB technology improves the convenience of mobile phones to operate smart homes

According to Top Industry Research Institute, a subsidiary of TrendForce, as voice assistants gradually mature, the center of smart homes is turning to smart speakers. However, voice assistants are mainly based on simple operations. To establish complex operations such as scheduling, mobile phones are still have a comparative advantage.

However, it is still not convenient to operate a smart home with a mobile phone. It is necessary to open the corresponding App of each home appliance one by one, which also leads to the gradual decline of the influence of mobile phones in the smart home.

Xiaomi’s “one-finger connection” UWB technology is a new UWB communication chip in mobile phones and various IoT devices. Compared with Wi-Fi and Bluetooth, UWB has higher accuracy and penetrating power. When the mobile phone points to the device, it directly enters the operation page, which improves the user experience, and the convenience of operation will drive the mobile phone to become one of the hubs of the smart home again.

In addition to accurate positioning, UWB technology will become another major advantage in smart homes with high security.

Current smart homes mainly use Wi-Fi and Bluetooth technologies to connect devices. For example, mobile phones are used to unlock smart door locks, and most of them rely on Bluetooth communication. However, with the gradual increase in the penetration rate of smart homes in the future, security will become one of the important keys.

UWB uses ToF (Time of Flight, time-of-flight) technology for spatial positioning. In addition to improving positioning accuracy, it also makes its security better than Wi-Fi and Bluetooth. High security will become another major advantage of UWB technology. .

Samsung and Xiaomi have the ability to vertically integrate mobile phones × IoT, which is expected to accelerate the adoption of UWB technology in mobile phones

The iPhone 11 series is the first smartphone to be equipped with a UWB chip, which is used to enhance the efficiency of AirDrop file transfer.

Samsung Galaxy Note20 Ultra is the first mobile phone equipped with UWB technology in the Android camp. In addition to enhancing the efficiency of file transmission, it also strengthens the SmartThings Find function, which can generate an AR screen to identify the location of the device, upgrade the smart search function, and will provide a Digital Key solution in the future. Whenever the user approaches the door, the Galaxy smartphone will unlock it for you.

However, the application of UWB in mobile phones has not yet impressed consumers. In the future, as the scale of smart homes continues to expand, Samsung and Xiaomi have not only released relevant blueprints for UWB applications, but also have the ability to vertically integrate mobile phones and IoT.

The two brands of mobile phone manufacturers accelerate the introduction of UWB technology into their own equipment to create a UWB ecosystem, which will accelerate the deployment of UWB communication chips by other brand mobile phone manufacturers.
