Abstract

A method and system for the wireless terminal receiving sensitivity performance test based on a data mode are provided. The method comprises: building a human body model, in which the upper limb of the model holds the device under test at a predefined distance in front of the head of the model; taking the antenna of the device under test as the origin to build a spherical coordinate and selecting a testing point in the spherical coordinate; placing the model under the circumstance of a full-anechoic chamber; enabling the device under test to work in a data mode, and collecting the receiving power at the testing point in the spherical placement system using the testing antenna, so as to obtain the total power receiving sensitivity of the device under test. In this way, the performance influence on the mobile terminal from the human body coupling of the human being in a data mode can be actually reflected, the reality is high and the usage is easy.
