Multi-Source Trajectory Fingerprint with 5G and Magnetic Field

The data was collected by a tester holding a Xiaomi 13 smartphone while walking and collecting data in an underground parking lot covering a 16x70m area. The data includes 5G radio features and geomagnetic field information.Collection Time: From 09:58 AM to 10:34 AM on July 13, 2024.Total Samples: 12,800Training Set (including validation set): 10,240Test Set: 2,560  Note: During the testing phase, the original Region ID should not be included, as it serves as the estimation target for REM. After completing the Region ID estimation, the predicted Region ID is incorporated into the fingerprint features and then fed into LEM for fine-grained localization.

本数据集由测试人员手持小米13智能手机，在覆盖16×70米范围的地下停车场内步行采集所得。数据集包含5G无线通信特征与地磁场信息。
采集时段：2024年7月13日上午09:58至10:34。
总样本量：12800，其中训练集（含验证集）10240，测试集2560。
注意：测试阶段不应包含原始区域ID（Region ID），因其为REM的估计目标；完成区域ID估计后，需将预测得到的区域ID并入指纹特征，再输入至LEM以执行细粒度定位。
