Radio terminal performance test device and method

Abstract

This invention discloses a performance test device and a method for radio terminal, in which, the device includes: a shield box with at least one antenna connected with an analog base station / controller out of the shield box, a test instrument connected with the being tested terminal in the box to test its radio performance, which controls the signal strength emitted to the radio terminal by the analog base station / controller, so that emitted signals can be controlled artificially, besides, tested terminals can work under single or multiple nets since one or many antennas are set in the box and shields radiation to outside test equipment and personnel and shields influence to being tested terminal from outside radiation interference of outside magnetic environment to guarantee accuracy of test result.

Description

technical field [0001] The present invention relates to a wireless terminal performance testing device, in particular to a terminal wireless performance testing device which can work in a single or multi-network condition, reduce test radiation and improve test repeatability; the present invention also relates to A wireless terminal performance test method, in particular a wireless terminal performance test method that enables the test environment of the terminal to be tested to be controlled, reduces test radiation and improves test repeatability, and belongs to the technical field of wireless communication. Background technique [0002] With the development and popularization of wireless communication technology, mobile phones have become the mobile information center of daily life. Standby and talk time are technical indicators that mobile phones, operators and ordinary consumers care about. General standby time=battery capacity / standby current; talk time=battery capacit...

Problems solved by technology

[0007] In the process of realizing the present invention, the inventor finds that the second test method has at least the following problems: although the second test method overcomes the deficiencies of the first method and can test wireless indicators, it still has the following defects: (1) Under the influence of multi-channel effect, the signal strength and transmission power received by mobile phones cannot be accurately controlled, and the test results in different locations are not comparable; (2) other external interference (such as different time periods during the day and night, different weather conditions, etc.) Uncontrollable, and the test done by the antenna connected to the simulated base station is a near-field test. Uncontrollable interference factors will lead to poor repeatability of the test; (3) When the mobile phone transmits at high power, it will cause great harm to the human body. The health of the testers is unfavorable; under the same transmission power, due to the influence of external conditions, the test results may have relatively large differences, and the repeatability is poor. The test results are only for reference and cannot be used as research, testing and inspection standards.
