Qualcomm Technologies and Xiaomi have successfully validated metre-level positioning with the Xiaomi 12T Pro powered by the Snapdragon 8+ Gen 1 mobile platform in Germany. Meter-level positioning significantly improves the location performance of smartphones, providing a superior user experience when using maps, driving and more location-based mobile applications.
Xiaomi leverages Qualcomm Meter-Level Positioning for smartphones with the Trimble RTX calibration service. The Xiaomi 11 Pro / Ultra was the first to commercially implement Qualcomm Meter-Level Positioning in the Chinese market.
Metre-level positioning accuracy can enhance the smartphone user experience in many scenarios, including using maps, driving and other mobile applications. Specifically, greater accuracy can be achieved in the following scenarios:
- When using online taxi apps, can provide drivers and passengers with accurate pick-up locations.
- When using fitness apps, it can accurately record the outdoor exercise track of users’ cycling and running.
- Optimised lane level accuracy, more map detail and more precise directions when using in-car real-time navigation applications.
Qualcomm’s metre-level positioning technology for smartphones combined with the Trimble RTX calibration service delivers extremely high positioning accuracy on commercial smartphones. When integrated with the Snapdragon mobile platform, Trimble RTX enhances the positioning performance of flagship handsets, enabling even greater accuracy.
The three parties have conducted high-precision verification tests (including driving tests) in several scenarios, including open suburban roads and urban highways. The test results show that the mobile terminal can achieve meter-level accuracy at a confidence level of 95%.
The relevant configuration is Xiaomi 12T Pro phone with LPDDR5 memory and UFS 3.1 storage, pre-installed Android 12-based MIUI 13 system. The 6.67-inch 120Hz AMOLED display, which supports HDR10+, Dolby Vision, typical brightness of 500 nits (900 nits peak), is protected by Gorilla Glass 5. The 200-megapixel camera is a Samsung ISOCELL HP1 sensor, 1/1.22 inches, with a pixel size of 0.64µm, and supports 4-in-1 and 16-in-1 photography.
