Method and system capable of quantitatively evaluating Wi-Fi network performance

Abstract

The invention discloses a method capable of quantitatively evaluating Wi-Fi network performance, an evaluation network comprises n ports, each port is provided with a one-to-one power divider, and themethod comprises the following steps: receiving a radio frequency signal through each port; equally dividing the radio frequency signal through the power divider and then sending the radio frequencysignal to other ports; calculating the transmission effect of the radio frequency signals by measuring the equally divided radio frequency signals received by other ports; wherein n is a natural number greater than 2. Compared with the prior art, the application has the following beneficial effects: the application provides a four-port communication network, and the radio frequency link between each port can be independently controlled to be opened or closed. And the throughput can be tested by quantitatively changing the intensity of the signal when the device is opened. In addition, the performance of the whole communication network can be evaluated, and the communication network can be expanded into a larger communication network through cascade connection.

Description

technical field [0001] The present application relates to the communication field, and in particular, relates to a method for quantitatively evaluating the performance of a Wi-Fi network. Background technique [0002] With the popularity of WI-FI and wearable devices, the network environment we use is becoming more and more complex. Because they are all in the same frequency band, such as the ISM frequency band 2.4G, and the very common 5G frequency band. However, many equipment manufacturers need to evaluate the performance of their own products. At this time, it is difficult to truly evaluate the RF index performance of their equipment and the processing ability of their own software due to environmental interference. Usually, a very open outdoor environment is used or an underground garage or a large shielded room is used, which greatly reduces the cost, efficiency, and construction of environmental equipment, and it is difficult to test the distance of several hundred m...

Problems solved by technology

However, many equipment manufacturers need to evaluate the performance of their own products. At this time, it is difficult to truly evaluate the RF index performance of their equipment and the processing ability of their own software due to environmental interference.

Usually, a very open outdoor environment is used or an underground garage or a large shielded room is used, which greatly reduces the cost, efficiency, and construction of environmental equipment, and it is difficult to test the distance of several hundred meters. accomplish

Secondly, we also want to obtain the performance and anti-interference ability of our own equipment in a noisy environment, but it is often difficult to calculate and analyze quantitatively and qualitatively due to interference in an open environment

[0003] At present, most companies do not pay attention to the optimization of their own performance. Basically, they test data in underground garages and open environments. However, due to differences in space and time each time, it is difficult to accurately measure performance.

It is also difficult to have a quantitative analysis of radio frequency performance and anti-interference ability

[0004] In addition, the pull distance test in an open environment requires a distance of several hundred meters or even a thousand meters to test the low signal and low rate conditions.

Moreover, due to the long distance, the power supply of equipment and the construction of the environment will be difficult
