Method and system for testing isotropic sensitivity of a terminal

摘要

Disclosed are a method and system for testing the isotropic sensitivity of a terminal, comprising: testing the received signal strength of a terminal at every theta/phi angle and antenna polarization direction, and generating a received signal strength pattern and a table of the correspondence between base station power and the received signal strength of the terminal; finding the best theta/phi angle and antenna polarization direction and testing the corresponding effective isotropic sensitivity; calculating the effective isotropic sensitivity at other theta/phi angles and polarization directions and integrating these to obtain the isotropic sensitivity of the terminal. The present invention thereby effectively reduces testing time and improves testing efficiency.

1. A method for testing Total Isotropic Sensitivity (TIS) of a terminal, comprising:
placing the terminal on a rotating table in a darkroom to create a communication connection with a base station simulator via a darkroom measuring antenna; rotating the rotating table to test a terminal received signal strength of the terminal at each Theta/Phi angle and in each antenna polarization direction, and to generate a terminal received signal strength direction map; generating a correspondence table between base station power levels and the terminal received signal strengths; searching for the best Theta/Phi angle and the best antenna polarization direction according to the terminal received signal strength direction map, and rotating the terminal to the best Theta/Phi angle and the best antenna polarization direction to test an Effective Isotropic Sensitivity (EIS) EISbest of all channels under test at the best Theta/Phi angle and in the best antenna polarization direction; calculating EISs at other Theta/Phi angles and in other antenna polarization directions according to the EIS EISbest and the correspondence table:
EIS=EISbest+(RXLEVELbest−RXLEVEL) where, RXLEVELbest is a terminal received signal strength at the best Theta/Phi angle and in the best antenna polarization direction, and RXLEVEL is the terminal received signal strength at the other Theta/Phi angles and in other antenna polarization directions; and integrating all the EISs to obtain the terminal TIS.
