Description

[Technical Field]

[0001] This invention relates to networking methods, and more particularly to a method, electronic device, and storage medium for improving wireless network coverage. [Previous Technology]

[0002] Indoor Wi-Fi signal strength mainly depends on the number, location, and power of Wi-Fi hotspots. Due to cost considerations, some large spaces, such as offices, shopping malls, factories, etc., are difficult to be fully covered by the signal, resulting in unsatisfactory communication quality. [Summary of the Invention]

[0003] In view of this, the present invention provides a method, electronic device and storage medium for improving wireless network coverage, thereby improving Wi-Fi coverage in edge areas by 2 to 3 times the traffic.

[0004] This invention provides a method for improving wireless network coverage, applied in an electronic device, comprising the following steps: importing field map data of a wireless network area; scanning multiple network sharing devices in the wireless network area using a radio frequency scanner based on the field map data to form a Wi-Fi mesh network; generating a Service Set Identifier (SSID) and Quality of Service (QoS) table based on the Wi-Fi mesh network; generating a White Channel List based on the Wi-Fi mesh network; providing a Multiple Device Support List for the network sharing devices based on the Wi-Fi mesh network; and allocating one or more network sharing devices to a user for internet access using Multi-User Multiple Input Multiple Output (MU-MIMO) technology based on the SSID, QoS table, White Channel List, and Multiple Device Support List.

[0005] This embodiment of the invention also provides an electronic device, which includes a memory, a processor, and a program for improving wireless network coverage stored in the memory and executable on the processor. When the program for improving wireless network coverage is executed by the processor, it performs the following steps: importing field map data of a wireless network area; scanning multiple network sharing devices in the wireless network area using the field map data and an RF scanner to form a Wi-Fi mesh network; generating a Service Set Identifier (SSI) Quality of Service (QoS) table based on the Wi-Fi mesh network; generating a white channel table based on the Wi-Fi mesh network; providing a multi-device support table for the network sharing devices based on the Wi-Fi mesh network; and allocating one or more network sharing devices among the network sharing devices to a user for internet access using Multiple User Multiple Input Multiple Output (MMI) technology based on the SSI, the white channel table, and the multi-device support table.

[0007] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0008] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0011] It should be noted that the descriptions involving "first," "second," etc., in this invention are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0012] Figure 1 is a schematic diagram of the ceiling-mounted network sharing device of the present invention used in an office. Figure 2 is a schematic diagram of the ceiling-mounted network sharing device of the present invention used in a building. The method for improving wireless network coverage of the present invention is mainly applied to network sharing devices with hotspot functionality, such as ceiling-mounted Wi-Fi access points (APs), ceiling-mounted Wi-Fi routers, or other non-ceiling-mounted network sharing devices. In Figure 2, the location of user A is covered by the wireless signal of only one network sharing device, the location of user B is covered by the wireless signal of two network sharing devices, and the location of user C is covered by the wireless signal of three network sharing devices.

[0013] Figure 3 is a flowchart of the steps of a method for improving wireless network coverage according to an embodiment of the present invention, applied to a processor of an electronic device. Depending on different needs, the order of the steps in the flowchart can be changed, and some steps can be omitted. The electronic device can be one of the network sharing devices (AP or router) or a central control device in the wireless network.

[0014] Step S1: Integrate field map data of a wireless network area, and scan multiple network sharing devices in the wireless network area using a radio frequency (RF) scanner based on the field map data to form a Wi-Fi mesh network.

[0015] Step S2: Generate a Service Set Identifier (SSID) and Quality of Service (QoS) table based on the Wi-Fi mesh network. Each SSID corresponds to a network sharing device, and the network sharing devices are sorted according to the traffic volume of each network sharing device.

[0016] Step S3: Generate a white channel list based on the Wi-Fi mesh network, wherein the received signal strength indication (RSSI) value of the network sharing device in the white channel list is less than 70 dBm.

[0017] For example, a 2GHz to 7.1GHz wireless scanner is used as a spectrum analyzer to scan the wireless network area at fixed intervals (e.g., 1 minute) to obtain the frequency bands used in the wireless network area, thereby generating the white channel list. The white channel list includes frequency bands recommended for use by network sharing devices (channels with RSSI < -70dBm). For example, network sharing device 1 provides 40 million bits per second (Mbps) bandwidth in the 2G band through Channel 3 (ch3) (2G_40M_ch3), network sharing device 2 provides 80Mbps bandwidth in the 5G band through Channel 80 (ch80) (5G_80M_ch80), and network sharing device 3 provides 160Mbps bandwidth in the 6G band through Channel 57 (ch27) (6G_160M_ch57).

[0018] Step S4: Provide a Multiple Device Support List for all network sharing devices according to the Wi-Fi mesh network. In this Wi-Fi mesh network, each user's sub-area within the wireless network area may be covered by the wireless signals of 1, 2, or 3 network sharing devices. The Multiple Device Support List indicates how many network sharing devices' wireless signals can cover each user's sub-area. In other words, a user covered by the wireless signals of multiple network sharing devices can preferentially select one or more network sharing devices with better signals to transmit data.

[0019] Step S5: Based on the service set identification code quality of service table, the white channel table and the multi-device support table, the network sharing device is allocated to the user to connect to the Internet through multi-user multiple input multiple output (MU-MIMO) technology.

[0020] The following example illustrates the implementation process of the method for improving wireless network coverage according to an embodiment of the present invention.

[0021] For example, users A and C require 320M bandwidth, while users B and D require 160M bandwidth. According to the multi-device support table, users C and D can be supported by 3 network sharing devices. User C requires more bandwidth than user D, therefore user C has higher priority than user D.

[0022] According to the white channel table, network sharing devices 1 to 4 currently provide network sharing services. Network sharing device 1 provides a bandwidth of 20Mbps to 320Mbps in the 6G band via channel 57 (ch57) (6G_20M→320M_ch57), network sharing device 2 provides a bandwidth of 20Mbps to 320Mbps in the 5GH band via channel 114 (ch114) (5G_20M→160M_ch114), network sharing device 3 provides a bandwidth of 20Mbps to 80Mbps in the 5GL band via channel 50 (ch50) (5G_20M→80M_ch50), and network sharing device 4 provides a bandwidth of 20Mbps to 40Mbps in the 2G band via channel 9 (ch9) (2G_20M→40M_ch9).

[0023] Based on the above bandwidth requirements and whether it is supported by multiple network sharing devices, the bandwidth allocation order for users A, B, C, and D is determined to be C→D→A→B, and the bandwidth allocation information is as follows:

[0024] User C: 160M of network sharing device 1 + 80M of network sharing device 2 + 80M of network sharing device 3;

[0025] User D: 80M of network sharing device 1 + 40M of network sharing device 2 + 40M of network sharing device 3;

[0026] User A: 320M of network sharing device 1; and

[0027] User B: 160M of network sharing device 1.

[0028] In addition, it should be noted that the present invention uses methods familiar to those skilled in the art to generate the SSID quality of service table, the white channel table and the multi-device support table, which will not be described in detail herein.

In this embodiment, the processor 210 is used to run code stored in the memory 220 or process data, for example, to run the system 230 for improving wireless network coverage.

[0032] It should be noted that Figure 4 is only an example to illustrate the electronic device 200. In other embodiments, the electronic device 200 may also include more or fewer elements, or have different element configurations.

[0034] FIG5 is a functional block diagram showing an electronic device according to an embodiment of the present invention, which is used to execute a method for improving wireless network coverage. The method for improving wireless network coverage according to an embodiment of the present invention can be implemented by a computer program in a storage medium, for example, memory 220 in electronic device 200. When the computer program implementing the method of the present invention is loaded into memory 220 by processor 210, it drives processor 210 of electronic device 200 to execute the method for improving wireless network coverage according to an embodiment of the present invention.

[0035] The electronic device 200 of the present invention, such as a network sharing device (AP or router) or a central control device in the wireless network, includes a network establishment module 310, a data establishment module 320 and a network management module 330.

[0036] The network establishment module 310 incorporates field map data of a wireless network area, and scans multiple network sharing devices in the wireless network area based on the field map data and a radio frequency (RF) scanner to form a Wi-Fi mesh network.

[0037] The data establishment module 320 generates a service set identification code quality of service table based on the Wi-Fi mesh network. Each SSID corresponds to a network sharing device, and the network sharing devices are sorted according to the traffic volume of each network sharing device.

[0038] The data creation module 320 generates a white channel table based on the Wi-Fi mesh network, wherein the RSSI value of the network sharing device in the white channel table is less than 70dBm.

[0039] For example, a 2GHz to 7.1GHz wireless scanner is used as a spectrum analyzer to scan the wireless network area at fixed intervals (e.g., 1 minute) to obtain the frequency bands used in the wireless network area, thereby generating the white channel list. The white channel list includes frequency bands recommended for use by network sharing devices (channels with RSSI < -70dBm). For example, network sharing device 1 provides 40 Mbps bandwidth in the 2G band through Channel 3 (ch3) (2G_40M_ch3), network sharing device 2 provides 80 Mbps bandwidth in the 5G band through Channel 80 (ch80) (5G_80M_ch80), and network sharing device 3 provides 160 Mbps bandwidth in the 6G band through Channel 57 (ch27) (6G_160M_ch57).

[0040] The data establishment module 320 provides a multi-device support table for all network sharing devices based on the Wi-Fi mesh network. In this Wi-Fi mesh network, each user's sub-area within the wireless network area may be covered by the wireless signals of 1, 2, or 3 network sharing devices. The multi-device support table specifies how many network sharing devices' wireless signals can cover each user's sub-area. In other words, a user covered by the wireless signals of multiple network sharing devices can preferentially select one or more network sharing devices with better signals to transmit data.

[0041] The network management module 330 allocates network sharing devices to users for internet access based on the service set identification code quality of service table, the white channel table and the multi-device support table, using MU-MIMO technology.
