Abstract:
1. A method for the wireless terminal radiation performance test based on a data mode, comprising: 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 a dual-polarized 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 total radiated power at the testing point in the spherical placement system using the dual-polarized antenna wherein the total radiated power collected at each testing point includes a horizontal polarization component and a vertical polarization component; obtaining the total radiated power of the device under test by steps of: respectively obtaining the total radiated power at each testing point according to formula (1): wherein TRP is the total radiated power of the current testing point, Ω is the solid direction angle of the current testing point in the spherical coordinate system, EIRP wherein TRP is the total radiated power of the device under test, N and M are multiple sampling intervals for θ and φ respectively, θ
