A method of using a single wifi terminal device to form a sub-local area network with anti-jamming capability

Abstract

The invention discloses a method for building a sub-local area network with anti-interference capacity by utilizing a single WiFi terminal device, WiFi Legacy STA is utilized to conduct environment assessment, and the optimum initialized parameter of Soft AP is provided; a system application simulation client and system logic layer WiFi simulate and realize the P2P Group networking of a single device; the system logic layer WiFi works on the Legacy STA and P2P Go simultaneously; the system logic layer WiFi utilizes the P2P Go to simulate the Soft AP; the system logic layer WiFi utilizes the P2P Go to bridge the Legacy STA as the upstream of the whole network node. On the premise of not increasing hardware cost, the method utilizes the single WiFi terminal device to realize the construction of the sub--local area network function with relatively high anti-interference capacity therein in the network environment of a local network.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for establishing a sub-local area network with high anti-interference ability by using a single WiFi terminal device. Background technique [0002] As we all know, WiFi, as the wireless communication method with the highest utilization rate at present, is closely related to people's life. However, the working frequency band of WiFi is strictly limited, which is divided into two categories: 2.4G and 5G. 2.4G has 13 channels in total, and only channels 1, 6, and 11 are independent of each other. Because 5G channels involve special purposes such as military affairs, other The channel also has its strict limitations. More and more routers work within the limited channel bandwidth, and the actual communication capability will inevitably be reduced to varying degrees due to various environmental interference factors. [0003] In general, a WiFi terminal device can work i...

Problems solved by technology

However, at present, for the system logic / hardware driver of the WiFi terminal device itself, in the Legacy STA mode, taking the Linux / Android system as an example, the adaptation layer used to connect the system and the driver is wpa_supplicant, which uniformly provides an event interface for the system / driver, while The adaptation layer used for standard SoftAP is Hostapd. Considering the system’s management strategy for WiFi, wpa_supplicant / Hostapd services are mutually exclusive. In terms of hardware, STA and standard SoftAP cannot multiplex TX / RX antennas, so from the perspective of the physical structure itself , on the same WiFi module, there is no good way to integrate the two working modes of WiFi
