The main problem is that the existing tests are basically carried out in a closed environment, while the WiFi usage scenarios are all carried out in various open environments (home, office, outdoor street, etc.). For WiFi STA The wireless signal received by the receiving end product will be interfered. Due to the difference between the test environment and the use environment, the accuracy of the test is directly low.

Embodiment 3
[0081] On the basis of the above examples, see Figure 5 , before step S40 also includes:
[0082] Step S10, judging whether the sight distance of the open space is within a preset range, and whether there are multiple rooms in the open space;
[0083] The line-of-sight of the selected space usually needs to meet 15 meters, which can be measured by the ranging sensor and judged in conjunction with the judgment program in the software; there must be more than three rooms in the open space, which can be completed through the camera and the judgment program; if At the same time, the above conditions are met before the following steps are performed, which is similar to the real environment and the accuracy of the test is higher;
[0084] Step S20, if yes, check the usage status of the frequency spectrum occupied by the WiFi signal of the set frequency band;
[0085] If the above two conditions are met at the same time, further call the spectrum occupied by the WiFi signal of the...
Embodiment 2
[0108] see Figure 7 , corresponding to the second embodiment of the test method for the above-mentioned wireless terminal receiving performance, the system further includes a position determining module 10, which is used to determine a preset position, a strong signal test position, a weak signal test position and a medium signal test in an open environment Location; No location determination module 10 includes:
[0109] A selection module 11, configured to select a candidate test location of the open environment according to three attenuation factors in the signal attenuation model;
[0110] According to the three attenuation factors in the signal attenuation model (straight-line distance attenuation, obstacle attenuation, multipath effect):
[0111] Point A will be used as a WiFi hotspot strong signal test point, which can also be fully explained from the WiFi signal propagation theory. Point A is a straight-line signal transmission model within the line-of-sight range, an...

Abstract
The invention discloses a method and system for testing the receiving performance of a wireless terminal, the method comprising: placing a wireless terminal on standby at a preset position in a preset open environment; placing a wireless router or a wireless access node in the open environment respectively Strong, medium and weak signal test positions; when the wireless terminal receives the signal, measure the maximum receiving data rate of the wireless terminal when the wireless router is in the current test position; when the wireless router or wireless access node is in the strong, medium and weak signal test When the maximum receiving data rate of the wireless terminal at the location is greater than the preset qualified quantitative value corresponding to the test location, it is determined that the wireless terminal is qualified; otherwise, it is determined that the wireless terminal is unqualified. The open test environment of the present invention is close to the use environment of the wireless terminal, and the interference received by the signal in the test is equivalent to that in use, the WiFi use environment is truly simulated, and the accuracy of the test of the receiving performance of the wireless terminal is improved.
Description
technical field [0001] The invention relates to the technical field of radio frequency testing, in particular to a method and system for testing the receiving performance of a wireless terminal. Background technique [0002] With the maturity and development of wireless communication technology, wireless products and wireless applications are emerging in people's field of vision, such as WiFi, Bluetooth, Zigbee module, NFC (Near Field Communication) and so on. And WiFi, the most popular wireless technology in this communication era, is getting closer and closer to our lives. For example, equipment for building a wireless LAN: wireless router (WiFi Router), wireless AP (WiFi Access Point, wireless access node), bridge (Network Bridge), etc.; various intelligent terminal devices (WiFiSTA) that need to connect to wireless LAN communication: Smart TV Smart TV, TV box, mobile phone, Tablet PC, Notebook, etc. [0003] How to measure and test the performance and eligibility of su...
