    What is Wi-Fi throughput

    Post time: Jun-28-2024

    Generally speaking, the Wi-Fi throughput is the actual maximum rate supported by the Wi-Fi device (AP/STA) on the uplink and downlink, which belongs to a limit test and is closer to the actual use scenario of users, especially in the increasingly wireless products and the design of wired network ports gradually fades out today, which is particularly important. The Wi-Fi throughput mentioned in this article is the Wi-Fi throughput test of the application layer, which is suitable for the application scenario of high data transmission. Wi-Fi throughput is a general concept, which needs to be divided into modes and channels in the actual test

    Such as IEEE 802.11n HT40 mcs7 ch1, IEEE 802.11ac HT80 mcs9 ch36 and so on.

    Note: MCS is a Modulation and coding scheme, different numbers represent different modulation coding methods, and different modulation methods correspond to different rates. For details, see 802.11n/ac protocol.

    According to the purpose (application scenario) of Wi-Fi throughput verification, there are various methods

    1. For example, when verifying Wi-Fi throughput inflection points, different attenuation values need to be set through the attenuator;

    2. For example, verify the coexistence performance of wireless systems in several typical scenarios:

    To verify the product coexistence performance of the application Wi-Fi+ Bluetooth combo chip (to verify the product Wi-Fi and Bluetooth slot allocation and channel avoidance mechanism, the principle is the same as that of 4G and Wi-Fi), the Bluetooth function of the product should be switched on and off for test;

    When a single Wi-Fi device tests throughput, plus Bluetooth devices, it can also be subdivided into two states: Bluetooth only connection and data transmission;

    In the scenario where Wi-Fi devices and Wi-Fi devices coexist, other Wi-Fi devices are added during the test. The devices can work in the same or adjacent channel of the current test, and can also be subdivided into two states: connection only and data transmission.

    3, for example, verify the impact of Wi-Fi driver, which is more obvious at close distance;

    4, for example, to verify antenna performance, it is necessary to distinguish different directions, angles and distances.

    5, For example, verify the impact of temperature on throughput. Various permutations and combinations of the above types can also be performed as required.
