Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application. The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions.
As shown in fig. 1, fig. 1 is a schematic structural diagram of a network architecture according to an embodiment of the present application. The network architecture includes an electronic device and a plurality of wireless Access nodes (APs), including a first AP.
Wherein the electronic device acts as a Station (STA) in the network architecture. Each AP notifies STAs around it by constantly sending Beacon frame (Beacon) messages, so that the STAs can search for an AP.
Among other things, the electronic devices may include various handheld devices, vehicle-mounted devices, wearable devices (e.g., smartwatches, smartbands, pedometers, etc.) with wireless communication capabilities, computing devices or other processing devices communicatively connected to wireless modems, as well as various forms of User Equipment (UE), Mobile Stations (MS), terminal Equipment (terminal device), and so on. For convenience of description, the above-mentioned devices are collectively referred to as electronic devices.
The AP is a bridge for communication between a wireless network and a wired network, and is a core device for establishing a Wireless Local Area Network (WLAN). It mainly provides mutual access between STAs and a wired lan, so that STAs within the signal coverage of the first AP can communicate with each other through it, and it is essentially impossible to construct a WLAN that can truly access the Internet without an AP. The AP in the WLAN corresponds to the role of the transmitting base station in the mobile communication network.
Currently, two common frequency bands for wireless communication between the STA and the AP are mainly available: a 2.4G band and a 5G band. The frequency range of the 2.4G frequency band is 2.4 GHz-2.4835 GHz. The frequency range of 5G is 5.15 GHz-5.825 GHz.
Wherein the STA and the AP perform wireless communication through a channel. The 2.4G frequency band is provided with 14 channels in total, but only the first 13 channels are allowed to be used in China. Each channel is 22MHz wide, only 20MHz is actually used to transmit data, and the other 2MHz is used to isolate the channels. 2.4G can be used with 83.5MHz, and most of the channels will overlap. The center frequencies of each channel are separated by 5 MHz. The mapping relationship of channels, center frequencies and frequency ranges in 2.4GHz is shown in table 1.
TABLE 1
| Channel with a plurality of channels | Center frequency (MHz) | Frequency range (MHz) |
| 01 | 2412 | 2401-2423 |
| 02 | 2417 | 2406-2428 |
| 03 | 2422 | 2411-2433 |

| 12 | 2467 | 2456-2478 |
| 13 | 2472 | 2461-2483 |
Wherein, the frequency band bandwidth is divided into 20MHz and 40 MHz. The anti-interference capability of 20MHz bandwidth is strong, but the data transmission speed is slow, and the anti-interference capability of 40MHz bandwidth is weak, and the data transmission speed is fast. Since there is mostly overlap between channels, there is collision between channels. The transmission efficiency of 20MHz bandwidth is higher than that of 40MHz bandwidth when the communication environment is poor, and the transmission efficiency of 40MHz bandwidth is higher than that of 20MHz bandwidth when the communication environment is good.
