    • A method using drive test data for propagation model calibration includes: step 1, obtaining original drive test data; step 2, selecting the data from the drive test data according to predefined conditions as effective drive test data; and step 3, extracting the effective drive test data to form a data file used for propagation model calibration. An apparatus using drive test data for propagation model calibration includes: a drive test data obtaining module, configured to obtain the drive test data in the regions to be calibrated; an effective drive test data generation module, configured to generate effective drive test data from the drive test data according to predefined conditions; and a data file generation module, configured to extract the effective drive test data to form a data file used for propagation model calibration. The present invention utilizes drive test data of existing networks to largely decrease the CW test work and reduce the network building cost. It is believed that the calibrated model can relatively accurately reflect the propagation characteristics in the field. Furthermore, base stations can be optimally allocated.

    • A stacked electrical connector structure including secondary electrical connectors stacked together along a direction perpendicular to a circuit board is provided. The stacked electrical connector includes an insulating body, signal terminal sets, groups of transmission terminals and a retaining block. A tail part extends from the end of each of the signal terminals, in which each of the transmission terminals is a blanking terminal and has two finger parts extending towards the tail parts of the signal terminals. The finger parts of each transmission terminal interfere with the tail part of each signal terminal. The retaining block has terminal channels for accommodating and fixing each transmission terminal, and the maximum dimension between two sides of each transmission terminal is slightly larger than the minimum dimension within each terminal channel of the retaining block, thereby fixing the relative position of the transmission terminals and the retaining block.
