A mobile terminal testing device has been granted a patent (Publication Number: US11874321B2) that includes a positioner within a radio anechoic box and measurement control means for measuring reception power from a mobile terminal using a test antenna. The device features rotation control means for orienting the mobile terminal in a spherical coordinate system, reception sensitivity test execution means for conducting reception sensitivity tests, and peak power measurement means for determining maximum reception power. The device also includes holding means for regulating orientations, throughput measurement end conditions, and output level setting means for adjusting test signal levels based on predetermined thresholds and variations. The device aims to accurately measure reception sensitivity and peak power in mobile terminals under test conditions.

Furthermore, the patent also covers a mobile terminal testing method that involves a similar setup with a positioner, rotation control means, reception sensitivity test execution means, measurement control means, and peak power measurement means. The method includes steps for selecting peak power candidates based on reception power ranges and determining peak power based on measurement results. By following these steps, the mobile terminal testing method ensures precise measurement of reception power and peak power in mobile terminals. This patented technology offers a comprehensive approach to testing mobile terminals, enhancing the accuracy and reliability of reception sensitivity and peak power measurements in the telecommunications industry.
