AI Technical Summary

Problems solved by technology

This method can effectively reduce the SAR value, but it will also reduce the radiation performance of the antenna, especially the antenna performance in the head-and-hands test scenario. Therefore, how to make the terminal meet both OTA and SAR tests is particularly important.

Embodiment 1

[0029] like figure 1 As shown, the present embodiment provides a processing method that takes into account both OTA and SAR testing, including the SAR proximity sensor 2 disposed on the left side of the main antenna area at the bottom of the rear end of the mobile terminal 1 and the SAR proximity sensor 2 disposed in the rear end of the mobile terminal 1 and used The acceleration sensor 3 for feeling the speed of the mobile terminal 1 specifically includes the following steps:

[0030] S1: Obtain the distance to the human body according to the SAR proximity sensor 2, and convert it into a capacitance value C 实时 ; Obtain the mobile terminal 1's activity speed according to the acceleration sensor 3, and convert it into the values ​​of speed Δθ and Δφ;

[0031] S2: according to the capacitance value C generated by the mobile terminal 1 during the test 实时 , the values ​​of speed Δθ and Δφ define three test scenarios: the first scenario is the SAR test scenario, the second scenar...

Abstract

The invention provides a processing method considering OTA and SAR tests. A test scene where a terminal is located is automatically detected through an SAR close-range sensor and an acceleration sensor. Different test scenes are respectively set according to a capacitance value C obtained by the SAR close-range sensor and speeds delta theta and delta phi obtained by the acceleration sensor, the first scene is an SAR test scene, and the second scene is an OTA test scene which comprises a head-hand test scene and other third test scenes. According to the embodiment of the invention, an SAR close-range sensor needs to be used in a main antenna area, and meanwhile, an acceleration sensor used by the terminal is combined, so that SAR and OTA performance test requirements are both considered. According to the method, the mobile terminal can be compatible with OTA and SAR tests, and finally the requirements of different markets are met.

Description

technical field [0001] The invention relates to the technical field of testing methods, in particular to a processing method that takes both OTA and SAR testing into consideration. Background technique [0002] During the communication process of the mobile terminal, the antenna will generate a certain amount of electromagnetic radiation, and the evaluation of the performance of the antenna is usually measured by OTA and SAR. [0003] OTA (Over The Air) test will simulate the wireless signal transmission scene of the product in the air, and this test method can take into account factors such as internal radiation interference of the product, product structure, antenna factors, RF chip transceiver algorithm, and even human influence. Considering it, it is a comprehensive test method to verify the radiation performance of wireless products in free space, which is very close to the actual use scene of the product. If the radiation performance of the mobile phone is not good, t...
