A switching method and device for a mu-mimo switch of a wireless router

Abstract

Aspects of the present invention disclose a switching method and device for a MU-MIMO switch of a wireless router. The CPU of the wireless router receives the interrupt control information of the interrupt switch, and restarts the wireless router according to the interrupt control information; when the CPU restarts the wireless router, it reads the The starting position of the volatile memory is changed from the starting position of one of the first and second partitions of the non-volatile memory to the starting position of the other partition, and the first and second partitions are respectively used to store the first image file and the second image file, the first image file is a driver program for a wireless router that adopts a PCIE2.0 interface and turns on the MU_MIMO function, and the second image file is a driver program for a wireless router that uses a PCIE1.1 interface and turns off the MU_MIMO function. Through the solution of the present invention, the wireless router can switch the PCIE2.0 / 1.1 interface and switch MU_MIMO at the same time through the combination of software and hardware according to the board-level noise in real time.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless local area network processing, and in particular to a method and device for switching a Multi-User Multiple-Input Multiple-Output (MU-MIMO) switch of a wireless router. Background technique [0002] Wireless routers can work in single-frequency and dual-frequency, for example, single-frequency wireless routers can use 2.4Ghz or 5Ghz to transmit data, and dual-frequency wireless routers can use 2.4Ghz and 5Ghz to transmit data at the same time. [0003] like figure 1 As shown, it is a schematic structural diagram of a smart home system in the prior art. The wireless router connects the smart electronic devices in the home through WIFI. For example, the wireless router connects mobile phones, computers, televisions, refrigerators, washing machines, air conditioners and lights and other electronic devices to realize network transmission. [0004] With the development and ...

Problems solved by technology

Generally, MU_MIMO needs the support of PCIE2.0. The clock frequency of PCIE2.0 is 2.5GHz, and 2.5GHz is too close to the frequency of 2.4G wifi. When using PCIE2.0 for high-speed transmission and the environment noise is large, PCIE2.0 will affect When the performance of 2.4G wifi is serious, it will lead to slow 2.4G network connection, video freeze, disconnection, etc.; if the wireless router / AP is switched to PCIE1.1, the maximum transmission rate is 2.5Gbps, and then after the impact of encoding efficiency, etc., It will limit the maximum transmission rate. At this time, if MU_MIMO is turned on, not only will it not improve the transmission performance, but it will also affect the normal use of PCIE1.1

[0011] At present, the MU_MIMO function is to switch the interface through the user's login into the routing page. It is fixed to PCIE1.1, which ensures that 2.4G wifi is normal, and high-speed transmission and MU_MIMO will be sacrificed; if it is fixed to PCIE2.0, high-speed transmission and MU_MIMO can be used, but it will interfere with 2.4G wireless, especially for long distances. There will be severe disconnection

And there is no board-level noise (Noise Floor) as a judgment of the user terminal. Among them, Noise Floor is also called floor noise, background noise, and background noise. It generally refers to the total noise in the system except useful signals. Many users The terminal has a high-speed transmission rate at the same time, and the MU_MIMO function is turned on, and it is found that the 2.4G long-distance wireless performance is even worse, and even video freezes, dropped calls, etc.
