Problems solved by technology

The test speed of RF performance largely depends on the number of test points, so too many test points will cause the test time to be too long
In addition, in the processing of test results, due to the non-uniform distribution of test points on the spherical surface, it is necessary to use spherical integrals for processing when calculating TRP and TIS, and the calculation process is more complicated.

Abstract

The invention discloses a space radio frequency testing method. The method comprises the following steps: a step of establishing a spherical coordinate system, a step of selecting test points, a step of testing and a step of processing data. The method causes the spatial test points to be distributed on the spherical surface as even as possible, can reduce the number of the test points under the condition of meeting the testing accuracy requirement, thus shortening the testing time and simplifying the processing algorithm of the testing results.

Description

technical field [0001] The present invention relates to the technical field of radio frequency testing of wireless communication products, in particular to a method for testing space radio frequency performance of wireless communication products (Over The Air, OTA). Background technique [0002] With the development of modern industry, all kinds of wireless communication products can only guarantee the quality of communication if they have good transmitting and receiving performance, that is, the total radiated power (Total Radiated Power, hereinafter referred to as TRP) must be higher than a certain value, and the omnidirectional receiving sensitivity (Total Isotropic Sensitivity, TIS) should be lower than a certain value, that is, the space radio frequency performance (Over The Air, hereinafter referred to as OTA) test index should be good. [0003] In order to ensure the normal use of mobile terminal equipment in the network, CTIA (Cellular Communications Standardization...
