Problems solved by technology

For example, when a POS terminal device realizes transaction data communication through a 4G network and at the same time realizes signal coverage of other wireless devices through Wi-Fi, if the mutual influence brought about by the inevitable coexistence mechanism of LTE and Wi-Fi cannot be accurately evaluated, it will May cause the device not to be used by some specific operators, or the user experience effect is poor
[0003] Existing coexistence test methods between LTE and Wi-Fi are generally based on subjective judgments, and are tested through actual networks. However, due to the uncontrollability of base station frequencies, it is impossible to simulate all scenarios, especially extreme LTE and Wi-Fi frequencies. It is very incomplete and may even draw the opposite test conclusion

Embodiment 1

[0100] This embodiment provides a terminal LTE and Wi-Fi coexistence test method. The terminal can be any intelligent terminal having both LTE and Wi-Fi communication means, such as an intelligent POS terminal, a smart phone, a tablet, and the like. In this embodiment, the terminal is an intelligent POS terminal as an example for expansion and description.

[0101] The test method of the present embodiment comprises:

[0102] 1. Use the OTA antenna darkroom test system to test the total omnidirectional sensitivity of LTE under high-power Wi-Fi transmission of smart POS terminals. That is, the omnidirectional sensitivity test scheme for Wi-Fi emission interference to LTE.

[0103] 1.1. Scenario Description

[0104]For many occasions that are not sensitive to battery life (such as adapters plugged in all the time, super-capacity batteries, etc.), smart POS terminals often establish application scenarios that convert LTE data connections into Wi-Fi sharing mode (that is, open ...

Embodiment 2

[0145] Please refer to figure 2 and Figure 4 This embodiment corresponds to Embodiment 1. It provides a test system for LTE performance under high-power transmission of terminal Wi-Fi, including an OTA antenna darkroom test system. The structural composition and connection relationship of the OTA antenna darkroom test system are described in Embodiment 1. It has already been explained and will not be repeated here.

[0146] The test system of this embodiment also includes a Wi-Fi signaling tester and an LTE signaling tester at the same time, so as to realize a complete test of the terminal LTE and Wi-Fi coexistence. Of course, it is also possible to equip only a Wi-Fi signaling tester or an LTE signaling tester according to actual needs, corresponding to the test of Wi-Fi emission interference to LTE, or the test of LTE emission interference to Wi-Fi.

[0147] Below, the test system that can realize the terminal LTE and Wi-Fi coexistence test is described:

Abstract

The invention provides a terminal LTE and Wi-Fi coexistence test method and system, the method comprises: adding a Wi-Fi signaling tester in an OTA antenna darkroom test system, and establishing a Wi-Fi signaling connection with the tested terminal in the darkroom; According to the preset test parameter template including the transmit power and the channel corresponding to different channel interference scenarios, the Wi-Fi antenna of the tested terminal is controlled by the Wi-Fi signaling tester to operate at the specified transmit power and the designated channel, and obtain The total omnidirectional sensitivity of LTE under the Wi-Fi high-power transmission of the tested terminal; similarly, the LTE signaling tester is added to the OTA antenna darkroom test system to obtain the Wi-Fi of the tested terminal under LTE high-power transmission. Total omnidirectional sensitivity. The invention simulates the interference frequency characteristics between LTE and Wi-Fi, and covers variousfrequency bands and channels, and the obtained test results are more relevant.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a terminal LTE and Wi-Fi coexistence test method and system. Background technique [0002] In order for terminals to better enjoy the convenience brought by technological development, advanced smart terminals (such as POS terminals) are becoming more and more popular, and basically must have LTE (Long Term Evolution, long-term evolution) and Wi-Fi (Wireless Fidelity, wireless Fidelity technology) two communication standards, due to the characteristics of the physical layer, some frequency bands will interfere with each other when used, which also brings design difficulties and challenges for the coexistence of the two. For example, when a POS terminal device realizes transaction data communication through a 4G network and at the same time realizes signal coverage of other wireless devices through Wi-Fi, if the mutual influence brought about by the inevitable coexistence mec...
