Abstract

The invention discloses a full-angle attenuation test method for a terminal wireless signal based on a use environment, which is used for testing signal intensity attenuation evaluation of a wireless signal received by a terminal.

Description

Terminal wireless signal full-angle attenuation test method based on use environment
Technical Field
The invention relates to the technical field of wireless radio frequency testing, in particular to a terminal wireless signal full-angle attenuation testing method based on a use environment.
Background
The existing radio frequency testing standard and mode are to use a wireless comprehensive tester such as CMW500, MT8821C and the like to cooperate with a standard microwave darkroom, wherein the microwave darkroom generally refers to a special room which is formed by adopting wave absorbing materials and metal shielding bodies and has very little transmission and reflection when electromagnetic waves are incident on a wall surface, a ceiling and the ground. The method has the effects of avoiding clutter interference of wireless communication products such as antennas, radars and the like in the darkroom and improving the accuracy and efficiency of the measured signals. The environment carries out relevant tests of wireless radio frequency, including TRP (omni-directional equivalent radiation power), TIS (omni-directional maximum receiving sensitivity) and the like.
The wireless technology used at present is various and comprises 2/3/4G, WIFI/NB and the like, and has the requirements of testing antenna indexes in free space, comprising
TRP: the total transmit power (Total Radiated Power) -is obtained by integrating the transmit power of the entire radiating sphere and averaging. It reflects the transmitting power condition of the whole machine of the product.
TIS: the total receiving sensitivity (Total Isotropic Sensitivity) -reflects the condition of the whole radiation spherical machine receiving sensitivity index. It reflects the receiving sensitivity of the whole machine. The parameter is used to determine the antenna performance level of the terminal, and thus infer the signal quality level that the terminal can achieve in actual use. If the parameter data is low, the signal level of the terminal is low, and the terminal is not suitable for use; and if the parameter data is high, the terminal signal level is high, and the terminal has good use experience in actual use.
Because TRP (omni-directional equivalent radiation power) and TIS (omni-directional maximum receiving sensitivity) tested by a standard microwave darkroom are theoretical thresholds of the terminal in an ideal standby environment, the test environment cannot be equivalent to the actual use condition of the terminal, and therefore, test data obtained by an experimenter often have larger access to actual use; and the test cannot accurately judge the signal attenuation degree of the terminal in actual use and the influence of signals in various working conditions of the terminal.
Therefore, the scheme provides a testing method, and the testing environment of the darkroom is changed by using the testing equipment of part of standard darkroom, so that the darkroom is similar to the using environment, and the real using condition is simulated, so that the full-angle signal attenuation condition of the terminal under the actual using condition is obtained.
