step 110, obtaining the client information accessed to the current wireless local area network.
Wherein, the client information includes: the number of clients, the average received signal strength value of each client, and the average throughput of each client. The average Received Signal Strength value may be a Received Signal Strength Indicator (RSSI) value of the Received Signal. The number of the clients is used for judging the adjustment amplitude of the LNA gain; the average RSSI value is used for judging the distance between the client and the AP; the average throughput includes the sending throughput and the receiving throughput, and is used for judging the current load condition.
The wireless lan can be understood as a wireless access point, fig. 2 is a functional block diagram of the AP rf front end in this embodiment, and the method of this embodiment is applied to the LNA, and is used to adjust the maximum value and the minimum value of the LNA. The sensitivity can be increased by adjusting the LNA value to be large, but interference in a larger range is received; the LNA value is reduced to reduce the receive sensitivity and also to reduce the received interference signal. In fig. 2, the PA is a power amplifier, the DAC is a digital-to-analog converter, which is also called a D/a converter, and the ADC is an analog-to-digital converter or an analog-to-digital converter.

Wherein the LNA value ranges from 0-100.
Specifically, if the number of the clients is 0, determining the maximum value and the minimum value of the low noise amplifier LNA according to the number of the clients and the average received signal strength value of each client, and determining the time allocation proportion of the maximum value and the minimum value of the LNA according to the average throughput of each client includes: setting the maximum value and the minimum value of the LNA to be a first set value; the time division ratio of the maximum and minimum values of the LNA is set to a first set ratio.
The first setting value may be 100, and the first setting ratio is 1: 1. The maximum value of the LNA can be represented by a1, the minimum value of the LNA can be represented by B1, when the number of the clients is 0, in order to maintain the maximum receiving sensitivity of the AP, the maximum value of the LNA needs to be set to a 1-100, the minimum value of the LNA needs to be set to B1-100, and the time allocation ratio of the maximum value of the LNA and the minimum value of the LNA is 1:1, so that the maximum coverage distance range of the hardware capability of the AP can be achieved, and the clients can be accessed smoothly.
When the number of the clients is 1, the AP preferentially guarantees the connection of the current client in the scenario, and considers other clients that may be connected.
Specifically, if the number of the clients is 1, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA according to the average throughput of each client may be: if the average received signal strength value of the client is larger than the first strength value, setting the maximum value of the LNA as a second set value, and setting the minimum value of the LNA as a third set value; if the average throughput of the client is smaller than or equal to the first throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client is greater than the first throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a second set proportion.
Wherein the first strength value may be 50, the second setting value may be 80, the third setting value may be 50, and the first throughput value may be 5 Mbps. The second set ratio may be 1: 3.
In this embodiment, when the average RSSI of the client is greater than 50, it indicates that the client is in a close range, and the LNA value is small, so as to ensure throughput. At this time, the maximum value of the LNA, a 1-20-80, is set; the minimum value of LNA B1-100-50 is set. If the average throughput of the client is less than or equal to 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 1; if the average throughput is greater than 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 3.
Specifically, if the number of the clients is 1, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA according to the average throughput of each client may be: if the average received signal strength value of the client is larger than the second strength value and smaller than the first strength value, setting the maximum value of the LNA as a second set value, and setting the minimum value of the LNA as the value obtained by subtracting the average received signal strength value from the first set value; if the average throughput of the client is smaller than or equal to the first throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client is greater than the first throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a second set proportion.

In this embodiment, if the average RSSI of the ue is less than 50 and greater than 20, it indicates that the ue is at a medium distance, and the LNA value does not need to be too large, so as to guarantee throughput. At this time, the maximum value a1 of the LNA is set to 100-20-80, and the minimum value B1 of the LNA is set to 100-RSSI, i.e., between 50 and 80. If the average throughput is less than or equal to 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 1; when the average throughput is more than 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 3.
Specifically, if the number of the clients is 1, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA according to the average throughput of each client may be: if the average received signal strength value of the client is smaller than the second strength value, setting the maximum value of the LNA as a first set value, and setting the minimum value of the LNA as a second set value; if the average throughput of the client is smaller than or equal to the second throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client is greater than the second throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a third set proportion.
The second throughput value is smaller than the first throughput value, the second throughput value may be 2Mbps, and the third set ratio may be 1: 2. In this embodiment, if the average RSSI of the client is less than 20, in this scenario, it indicates that the client is at a long distance, the LNA value is not too small, the throughput is guaranteed, and the client cannot be disconnected. At this time, the maximum value a1 of the LNA is set to 100, and the minimum value B1 of the LNA is set to 100-20 to 80. If the average throughput is less than or equal to 2Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 1; when the average throughput is more than 2Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 2.
Through the arrangement, when only one client is accessed to the AP, the scene where the client is located is tracked through the RSSI and the throughput, the throughput of the client can be well ensured, and meanwhile, the potential remote client access to the AP is not influenced.
In this embodiment, when the number of the clients is greater than or equal to 2, not only the short-distance client but also the long-distance client need to be guaranteed in the scene.
Specifically, if the number of the clients is greater than or equal to 2, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA may be determined according to the average throughput of each client: if the average received signal strength value of each client is greater than the first strength value, setting the maximum value of the LNA as a second set value, and setting the minimum value of the LNA as a third set value; if the average throughput of the client is smaller than or equal to the first throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client is greater than the first throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a third set proportion.
In this embodiment, if the average RSSI of all the clients is greater than 50, in this scenario, it is indicated that the clients are all in a close range, and the LNA value is small, so that the throughput is guaranteed. At this time, the maximum value a1 of the LNA is set to 100-20-80, and the minimum value B1 of the LNA is set to 100-50. If the average throughput is less than or equal to 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 1; if the average throughput is more than 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 3.
Specifically, if the number of the clients is greater than or equal to 2, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA may be determined according to the average throughput of each client: if the average received signal strength value of each client is smaller than the second strength value, setting the maximum value of the LNA as a first set value, and setting the minimum value of the LNA as a second set value; if the average throughput of the client is smaller than or equal to the second throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client is greater than the second throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a third set proportion.
In this embodiment, if the average RSSI of all the clients is less than 20, in this scenario, it is indicated that all the clients are in a long distance, the LNA value is not too small, the throughput is guaranteed, and the clients cannot be disconnected. At this time, the maximum value a1 of the LNA is set to 100, and the minimum value B1 of the LNA is set to 100-20 to 80. If the average throughput is less than or equal to 2Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 1; if the average throughput is greater than 2Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 2.
Specifically, if the number of the clients is greater than or equal to 2, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA may be determined according to the average throughput of each client: if the average received signal strength value of one part of the clients is greater than or equal to the first strength value and the average received signal strength value of the other part of the clients is less than the first strength value, acquiring the minimum average received signal strength value of each client, and setting the maximum value of the LNA as a second set value; if the minimum average received signal strength value is greater than the second strength value, setting the minimum value of the LNA as the first set value minus the minimum average received signal strength value; if the minimum average received signal strength value is smaller than the second strength value, setting the minimum value of the LNA as a second set value; if the average throughput of the client side with the average received signal strength value larger than or equal to the first strength value is smaller than or equal to the first throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client side with the average received signal strength value larger than or equal to the first strength value is larger than the first throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a third set proportion.
In this embodiment, if the average RSSI of some clients is greater than or equal to 50 and the average RSSI of some clients is less than 50, in this scenario, it is described that some clients are in a medium-long distance and some clients are in a short distance, and throughput of the short-distance clients is preferentially ensured, and meanwhile, the long-distance clients do not drop. At this time, the maximum RSSI value is recorded as RSSI _ MAX, the minimum RSSI _ MIN is recorded as RSSI _ MIN, the maximum LNA value a1 is set to 80, the minimum LNA value B1 is set to 100-RSSI _ MIN when RSSI _ MIN is greater than 20, and the minimum LNA value B1 is set to 100-20-80 when RSSI _ MIN is less than 20. When the average throughput of the short-distance client is less than or equal to 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 1; when the throughput of the short-distance client is more than 5Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 2.
Specifically, if the number of the clients is greater than or equal to 2, the maximum value and the minimum value of the low noise amplifier LNA are determined according to the number of the clients and the average received signal strength value of each client, and the time allocation ratio of the maximum value and the minimum value of the LNA may be determined according to the average throughput of each client: when the average received signal strength value of each client meets other conditions, acquiring the minimum average received signal strength value in each client, and setting the maximum value of the LNA as a first set value; if the minimum average received signal strength value is greater than the second strength value, setting the minimum value of the LNA as the first set value minus the minimum average received signal strength value; if the minimum average received signal strength value is smaller than the second strength value, setting the minimum value of the LNA as a second set value; if the average throughput of the client is smaller than or equal to the second throughput value, setting the time distribution proportion of the maximum value of the LNA and the minimum value of the LNA as a first set proportion; and if the average throughput of the client is greater than the second throughput value, setting the time distribution proportion of the maximum LNA value and the minimum LNA value as a third set proportion.
In this embodiment, for other scenarios in which the number of clients is greater than or equal to 2, the maximum value a1 of the LNA is set to 100, when RSSI _ MIN is greater than 20, the minimum value B1 of the LNA is set to 100-RSSI _ MIN, and when RSSI _ MIN is less than 20, the minimum value B1 of the LNA is set to 100-20-80. When the average throughput is less than or equal to 2Mbps, the time distribution ratio of the maximum value to the minimum value is 1: 1; when the average throughput is more than 2Mbps, the time allocation ratio of the maximum value to the minimum value is 1: 2.
Through the arrangement, when a plurality of clients are accessed to the AP, the scenes where the clients are located are tracked through the RSSI and the throughput, the close-range STA throughput can be well guaranteed, the long-range throughput is considered, and meanwhile, the large influence of interference on the throughput of the close-range client A due to the fact that the LNA is always at the maximum value caused by the long-range client is avoided.
