Description

Technical Field

[0001] This application belongs to the field of testing technology, specifically relating to a WiFi overall performance testing system for wireless devices. Background Technology

[0002] Open environments contain numerous WiFi electronic devices, generating dense co-channel signal interference during operation. This presents two core challenges to the wireless performance testing of WiFi products under verification: first, test data fluctuates significantly, failing to reflect the product's true performance; second, invalid test results are easily generated, severely impacting testing efficiency and accuracy. To address these issues, a specific testing system and supporting methods are needed to accurately verify the key wireless performance characteristics of WiFi products, including: extreme throughput performance, RVR (Range Coverage, Velocity Rate, Reliability), overall directionality performance, and anti-interference performance. By employing specialized testing systems and methods, the influence of environmental interference on test results can be eliminated, enabling accurate and stable evaluation of the product's wireless performance.

[0003] Chinese patent application CN116761204A discloses a WiFi throughput testing system, comprising a first shielded box, a second shielded box connected to the first shielded box via a shielded cable, and a control device disposed outside the first shielded box. The first shielded box contains a router, an attenuator connected to the router via a shielded cable, and a first antenna interface connected to the router via a shielded cable. The second shielded box contains a WiFi device under test and a WiFi antenna connected to the first antenna interface via a shielded cable. The control device is connected to the router via a network cable and is used to set the router's parameters and test throughput. During testing, the attenuator adjusts the signal strength of the WiFi antenna to a first strength and a second strength, respectively, to simulate long-distance and short-distance communication, and the throughput data under these scenarios is recorded. However, this system can only determine the WiFi throughput rate and cannot predict the directionality or anti-interference capability of the WiFi product, nor can it capture logs in real time to analyze and optimize WiFi performance when necessary.

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] like Figure 1 and Figure 2 As shown, in one embodiment of this application, a WiFi overall performance testing system for a wireless device includes: At least one first shielding box 1, a first debugging adapter 5 and an RF adapter are provided inside the first shielding box 1, and a turntable 4 is also provided inside the first shielding box 1; An antenna is also provided inside the first shielding box 1, and the antenna is connected to the first radio frequency adapter 9 via a radio frequency cable; At least one second shielding box 8, a first debugging adapter 6 and a second radio frequency adapter 10 are provided inside the second shielding box 8; at least one second shielding box 8 and at least one of the first shielding boxes 1 are integrally formed; A router and a signal attenuator are also installed inside the second shielding box 8. The antenna channels on the router are connected to the signal input port of the signal attenuator through radio frequency cables, and the signal output port of the signal attenuator is connected to the second radio frequency adapter 10 through radio frequency cables.

[0019] This embodiment adds turntable 4, debugging adapter, RF adapter, etc., enriching the test content and enabling three-dimensional and multi-faceted verification of the overall WiFi performance of wireless devices. The near-point extreme performance test can intuitively reflect the maximum throughput rate of WiFi; the RVR test can determine the range capability or wall penetration capability of wireless products, as well as whether the algorithms of each modulation rate are reasonable; and the directionality test of turntable 4 can determine the performance of WiFi at different angles, so as to optimize the overall antenna performance.

[0020] This embodiment also includes: a third radio frequency adapter interface disposed outside the first shielding box 1 and a fourth radio frequency adapter interface disposed outside the second shielding box 8, wherein the third radio frequency adapter interface and the fourth radio frequency adapter interface are connected by radio frequency cables.

[0021] The inner wall of the first shielding box 1 is also provided with an antenna bracket 2, which is used to install the antenna. More preferably, the antenna is a rod antenna.

[0022] The antenna is also connected to an interference signal transmitter that emits interference signals at different frequencies. The interference signals emitted by the transmitters simulate interference signals present in real-world user scenarios, thus verifying the anti-interference performance of the WiFi.

[0023] In addition, there is a first debugging adapter 5 inside the first shielded box 1, and a first debugging adapter 6 inside the second shielded box 8. The debugging serial port of the DUT test equipment can be connected through the first debugging adapter 5 and the first debugging adapter 6 so that the logs during the test can be printed in real time on the computer, thereby more efficiently analyzing and solving the problems encountered in the test process.

[0024] In this embodiment, the second shielding box 8 also has casters 7 at the bottom, which can be moved freely and easily.

[0025] Wave-absorbing material 3 is provided inside the first shielding box 1.

[0026] In this embodiment, the signal attenuator includes a first signal attenuator and a second signal attenuator. The antenna channels on the router are connected to the signal input ports of the first signal attenuator and the second signal attenuator respectively via radio frequency cables. The signal output ports of the first signal attenuator and the second signal attenuator are connected to the second radio frequency adapter 10 via radio frequency cables.

[0027] More preferably, the first signal attenuator includes a 2.4G signal attenuator.

[0028] More preferably, the first signal attenuator includes a 5G signal attenuator.

[0029] The signal attenuator, the router, and the turntable 4 are connected to the switch via network cables to form the same local area network. The router's WLAN port is connected to the external network, and the network cable is then connected to a PC for control and operation.

[0030] In this embodiment, the first shielding box and the second shielding box are also equipped with a power supply module.

[0031] Specifically, the 2.4G / 5G antenna channels on the router are connected to the signal input ports of the 2.4G / 5G signal attenuator via RF cables; the signal output ports of the 2.4G / 5G signal attenuator are connected to the second RF adapter 10 inside the second shielded box 8 via RF cables. The fourth RF adapter outside the second shielded box 8 is also connected to the third RF adapter outside the first shielded box 1 via RF cables. The 2.4G / 5G signal attenuator, router, and turntable 4 are connected to a switch via network cables to form a single local area network. The router's WLAN port is connected to the external network, and then connected to a PC via a network cable. Finally, the PC is used for control and operation. Alternatively, a CMW500 comprehensive testing instrument (or other signal generating equipment) can be used to set different frequency interference signals, which are then connected to the antenna inside the first shielded box via RF cables to achieve interference source output.

[0032] In practical applications, when testing near-point limit throughput performance, the DUT test equipment is placed at the center of the state, and the antenna height of the DUT equipment is consistent with the height of the rod antenna inside the first shielding box 1. The signal attenuator attenuation value is set to 0. On the computer, the corresponding parameters such as channel (1, 2, 3...13), working bandwidth, and frequency (2.4G or 5G) can be set through the router's backend management to perform the test.

[0033] During RVR performance testing, the DUT test device is placed in the center position, and the antenna height of the DUT device is consistent with the height of the rod antenna inside the first shielding box 1. On the computer, the parameters corresponding to the channel (1, 2, 3...13), working bandwidth, and frequency (2.4G or 5G) can be set through the router's backend management. On the computer, the attenuation value of the attenuator can be adjusted from 0 to 90dB through the attenuator control software, and the throughput data under different attenuation values ​​is recorded (generally, the attenuation step is 2dB).

[0034] During directional testing, the DUT test equipment is placed at the center of the state. The antenna height of the DUT equipment is consistent with the height of the rod antenna inside the first shielding box 1. The signal attenuator attenuation value is set to 50dB (generally a fixed attenuation value is used). On the computer, the parameters corresponding to the channel (1, 2, 3...13), working bandwidth, and frequency (2.4G or 5G) can be set through the router's backend management. Then, the turntable is controlled by the turntable 4 control software on the computer to rotate in 30° steps, and the throughput data at each angle is recorded. Finally, a radar chart is generated to determine the radiation performance of the whole machine at each angle.

[0035] For the anti-interference test, place the DUT test equipment at the center position, with the antenna height of the DUT equipment consistent with the height of the rod antenna inside the first shielding box 1. The interference source emits an interference signal with a fixed signal strength (it can send WiFi interference signals, Bluetooth interference signals, and 4G band interference signals), and the attenuator ranges from 0 to 90dB. On the computer, the channel (1, 2, 3...13), working bandwidth, and frequency (2.4G or 5G) can be set through the router's backend management to perform the test.
