It should be noted that the throughput is the sum of data amount correctly transmitted in a preset time period, and the throughput is an important index for measuring the data transceiving capability of the terminal and is also one of important indexes for measuring the wireless communication performance of the terminal, so that testing the throughput is a necessary way for determining the bottleneck of the wireless communication performance.
In order to test throughput closer to a use scene and accurately position the wireless communication performance bottleneck of a terminal, the application provides a throughput testing system based on the terminal, and the system at least comprises a channel simulation component, a testing terminal and an upper computer.
The channel simulation assembly is used for simulating an original signal into a wireless test signal matched with a channel model according to the channel model corresponding to the preset signal transmission environment, and outputting the wireless test signal to the transmitting antenna for transmitting. The test terminal is provided with a receiving antenna, and the receiving antenna is used for receiving the wireless test signal transmitted by the transmitting antenna. The upper computer is electrically connected with the channel simulation assembly and the test terminal and used for determining the throughput of the test terminal according to the wireless test signals received by the test terminal.
The channel simulation component abstractly describes the preset signal transmission environment through a channel model. The channel model represents the physical characteristics of the preset signal transmission environment through a series of wireless channel characteristic parameters, and then the propagation mechanism of the wireless signals is accurately described. The preset signal transmission environment is an actual transmission environment of a wireless signal predetermined by a developer, and may be, illustratively, an environment in which a router is placed in a living room and a terminal is placed in the room, wherein the environment may be divided into a case where a wall or N walls are separated between the router and the terminal, or a transmission environment in which the router is placed in an entrance and the terminal is placed in the living room. Because the same wireless signal may show completely different transmission characteristics in different actual transmission environments, the original signal is simulated to be transmitted in a preset signal transmission environment through the channel simulation component, so that the test can be performed closer to an actual use scene, and the throughput of the test terminal in the actual transmission environment can be more reliably evaluated.
The original signal is a known signal, because the frequency band in which the wireless router operates at present is generally divided into two frequency bands of 2.4GHz and 5GHz, and the transmission power is generally 50mW, therefore, in a preferred embodiment, the original signal can be set to the frequency band of 2.4GHz or 5GHz, and the transmission power is set to 50mW, so as to be closer to the use scenario. The 2.4GHz band has short frequency, so that the penetration is strong, the transmission distance is long, and the anti-attenuation capability is low; the 5GHz has high relative stability and strong anti-interference capability, but has poor wall penetrating capability and small coverage range.
In another embodiment, a plurality of original signals may be set, and different original signals are simulated to be transmitted in the same preset signal transmission environment by using the channel simulation component, so that the throughput of the test terminal when different original signals are transmitted in the same preset signal transmission environment is tested, and the throughput of the test terminal is more comprehensively and reliably evaluated.
The test terminal is a terminal that performs communication using a wireless signal, and may have one receiving antenna or a plurality of receiving antennas. The test terminal can be a whole terminal such as a television, a computer, a mobile phone and the like. Illustratively, if the test terminal is a television, and the position and the direction of the receiving antenna of the test terminal on the television are fixed, so that the radiation field shape and the gain of the antenna are determined, the television is placed in a test environment as the test terminal, and the inhibiting effect of other components of the television on the antenna receiving or transmitting communication signals can be taken into consideration, so that the test is closer to the actual use scene, and the wireless communication performance of the television can be more reliably evaluated.
The upper computer is a computer which can send out specific control commands, the commands are transmitted to the lower computer by operating preset commands, and the lower computer controls equipment to complete various operations. In this embodiment, the upper computer may be electrically connected to the channel simulation component and the test terminal through a serial bus, and may also be electrically connected to the channel simulation component and the test terminal through an ethernet, and the upper computer may be configured to control the channel simulation component to simulate a preset signal transmission environment, and may also be configured to obtain a wireless test signal received by the test terminal, and analyze and determine throughput of the test terminal.
In one embodiment, the terminal-based throughput testing system may further include: and the wireless channel acquisition instrument is used for acquiring test data of a wireless channel under a preset signal transmission environment so that the upper computer establishes a channel model corresponding to the preset signal transmission environment according to the test data.
Specifically, the intensity of the test signal passing through each obstacle and the signal intensity attenuation of each transmission path can be detected according to the number of obstacles in a preset signal transmission environment and a plurality of groups of signal transmission paths generated due to the existence of the obstacles, the intensity of the test signal passing through each obstacle and the signal intensity attenuation of each transmission path are used as test data and transmitted to the upper computer, and therefore the upper computer can establish a channel model matched with the preset signal transmission environment according to the test data.
In one embodiment, the channel simulation component may include a wireless channel simulator and an adjustable attenuator. The wireless channel simulator is used for simulating the influence of multipath fading factors in a preset signal transmission environment on an original signal; the adjustable attenuator is used for simulating the influence of path fading factors in a preset signal transmission environment on an original signal.
The fading of the wireless channel includes multipath fading, which is that the receiving end receives electromagnetic waves arriving through several paths such as refraction, reflection and direct incidence due to the existence of an obstacle between the transmitting end and the receiving end, and the received signal is in a fading state due to inconsistent phases of the electromagnetic waves arriving through different paths and time-varying characteristics. Path fading refers to the loss caused by the propagation of electromagnetic waves in space, and the path loss is caused by the radiation spread of the transmitted power and the propagation characteristics of the channel. Where fading refers to the relative value of the mean value of the power of the received signal relative to the mean value of the power of the transmitted signal, as is well known to those skilled in the art, in db.
The wireless channel simulator at least comprises a radio frequency signal receiving module, a quantization module, a signal simulation module and a signal sending module according to functional division. The radio frequency signal receiving module is used for receiving an original signal, the quantization module is used for carrying out down-conversion and analog-to-digital conversion processing on the original signal and sending the processed digital signal to the signal simulation module, and the signal simulation module is used for simulating the influence of multipath loss factors in a preset signal transmission environment on the original signal, transmitting the simulated signal to the signal sending module and simulating a wireless test signal of the original signal after transmission in the preset signal transmission environment.
An adjustable attenuator is used for reducing the power of an original signal, common attenuation values comprise 3db, 6db, 10db, 20db, 30db, 50db and the like, in the present embodiment, the adjustable attenuator is used to simulate the influence of the path loss factor on the original information in the preset signal transmission environment, it should be noted that the preset signal transmission environment of the present application includes a home environment, and the home environment can be considered as having a transmission distance of 10 meters to 100 meters, because the indoor environment is not open, barriers such as multi-surface walls and the like may exist, when electromagnetic waves pass through the walls, the loss is greater than that of the electromagnetic waves passing through the air, therefore, the loss caused by the wall wireless signal in the preset signal transmission environment can be tested, for example, if the attenuation value of the original signal passing through a wall with a known material and thickness is detected to be 30db, the influence of the wall on the original signal can be reflected by adjusting the parameters of the adjustable attenuator.
In one embodiment, the transmitting antenna and the testing terminal can be arranged in the same anechoic chamber, the anechoic chamber is a special space formed by adopting wave-absorbing materials and metal shields and is used for absorbing external electromagnetic waves incident to the wall surface, ceiling or ground of the anechoic chamber, so that the external electromagnetic wave interference can be conveniently eliminated, and a clean and interference-free testing environment can be established.
In one embodiment, the terminal-based throughput testing system further comprises a turntable for placing the test terminal, wherein the turntable is electrically connected with the upper computer and rotates according to a control signal sent by the upper computer, so that the terminal-based throughput testing system is used for testing throughput based on different angles.
Specifically, the test terminal can be placed on a turntable rotating by 360 degrees, the test terminal can be connected with an upper computer through the Ethernet, and the upper computer can test the throughput of the test terminal based on different turntable angles under the same channel model. Therefore, the influence of multipath effect between the transmitting antenna and the receiving antenna on the test result can be reduced.
In one embodiment, the original signal may be generated by the host computer and sent to the channel simulation component, and in other embodiments, the original signal may be generated by another device and sent to the channel simulation component, without limitation.

Step S230, determining the throughput of the test terminal according to the wireless test signal received by the test terminal.
As described in the foregoing system embodiment, the test terminal may be connected to the upper computer through an ethernet, so that the upper computer may obtain relevant information of the test terminal receiving the wireless test signal, for example, the test terminal actively sends the relevant information of the test terminal receiving the wireless test signal to the upper computer, or the test terminal sends the relevant information of the test terminal receiving the wireless test signal to the upper computer according to a control instruction sent by the upper computer, which is not limited in this embodiment.

Therefore, based on the method provided by the embodiment, the throughput test of the test terminal can be controlled through the upper computer, and the throughput of the test terminal is calculated by the upper computer, so that the method is very convenient. And because the wireless test signal received by the terminal is obtained by simulating the original signal to be transmitted in the preset signal transmission environment, the whole test terminal is equivalent to the wireless signal received in the real signal transmission environment, and therefore the throughput obtained by the upper computer can reliably reflect the throughput in the actual use environment of the terminal.
