Method and apparatus for switching MU-MIMO switch of wireless router

Abstract

Multiple aspects of the invention disclose a method and apparatus for switching a MU-MIMO switch of a wireless router. The method comprises the following steps: a CPU of the wireless router receives interruption control information of an interruption switch, and restarts the wireless router according to the interruption control information; the CPU reads a starting position of a non-volatile memory when restarting the wireless router, and switches from the starting position of one subarea of a first subarea and a second subarea of the non-volatile memory to the starting position of the other subarea, wherein the first subarea and the second subarea are respectively used for storing a first mirror image file and a second mirror image file, the first mirror image file is a driving program used by the wireless router for adopting a PCIE2.0 interface and opening a MU-MIMO function, and the second mirror image file is a driving program used by the wireless router for adopting a PCIE 1.1 interface and closing the MU-MIMO function. By adoption of the scheme of the invention, the wireless router switches the PCIE2.0 interface and the PCIE 1.1 interface by the combination of software and hardware according to the board level noise, and meanwhile switches the MU-MIMO at the same 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] Such as 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 a...

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.
