[0029] It should be noted that the PWL long-distance transmission networking device of the present application can be used in the field of communication technology, and can also be used in any field other than communication. The application field of the PWL long-distance transmission networking device of the present application is not limited.

[0030] Figure 1 A schematic diagram of an application scenario of a PWL long-distance transmission networking device provided in an embodiment of the present application is given as an example in combination with the illustrated scenario: in a wireless LAN communication solution, a LAN terminal device establishes a wireless connection with a network device, and a network device establishes a wireless connection with a LAN cloud platform, and data forwarding between the LAN terminal device and the LAN cloud platform is realized through the network device.

[0031] Exemplarily, the network device is a network device dedicated to the local area network, which is used to forward data of the local area network. The dedicated network device can prevent public network devices from accessing the wireless local area network, thereby effectively ensuring the security of local area network communications.

[0032] Combined with the scenario example, in industries or fields involving confidentiality, there are high requirements for the confidentiality of communication data. Communicating through a wireless LAN can avoid the leakage of important data and thus improve the security of communication.

[0033] For example, wireless LANs have limited usage scenarios. To reduce costs, LAN-specific network equipment is deployed in significantly fewer quantities than public network equipment. Consequently, the coverage of wireless LANs is also smaller. For mobile LAN terminals, when they are at the edge of or outside the coverage area of ​​the wireless LAN, poor signal quality can affect their communication quality.

[0034] In related technologies, when the wireless LAN signal quality is poor, communication between LAN terminal devices is achieved by connecting them to the public network. This technology allows for communication, but there are security issues with communicating through the public network.

[0035] The PWL long-distance transmission networking device provided in this application is intended to solve the above technical problems of the prior art.

[0036] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0037] Figure 2 A schematic diagram of the structure of a PWL long-distance transmission networking device provided in an embodiment of the present application includes: a local area network terminal device, a wireless access point, a mobile convergence gateway, and a local area network cloud platform, wherein:

[0038] The LAN terminal device establishes a wireless connection with the wireless access point, and the wireless access point is used to connect the LAN terminal device to the wireless LAN;

[0039] The wireless access point establishes a wireless connection with the mobile convergence gateway via the first radio frequency antenna of the wireless access point. The wireless access point includes a protocol encryption chip. The wireless access point is used to convert non-standard data of the local area network terminal device into standard data that complies with the wireless local area network protocol through the protocol encryption chip, so as to realize data forwarding between the local area network terminal device and the mobile convergence gateway.

[0040] The mobile convergence gateway establishes a wireless connection with the LAN cloud platform. The mobile convergence gateway includes a cellular modem. The mobile convergence gateway is used to establish a cellular backhaul link of the wireless LAN through the cellular modem to realize data forwarding between the wireless access point and the LAN cloud platform.

[0041] Exemplarily, the LAN terminal device is a terminal device dedicated to the LAN, and the communication of the LAN terminal device in the wireless LAN can meet the confidentiality or security requirements of the LAN terminal device.

[0042] Exemplarily, the local area network terminal device is a PWL device, and the PWL device is only used for communication in the PWL network.

[0043] Optionally, the local area network terminal device includes but is not limited to at least one of the following: a mobile phone, a laptop computer, a tablet computer, a wearable device (such as smart glasses or a smart watch), or an intelligent robot.

[0044] For example, a mobile convergence gateway is used to establish a wireless local area network (WLAN). Devices within the WLAN range can access the WLAN and communicate. To enhance communication security, an identity authentication scheme is added to the WLAN established by the mobile convergence gateway to verify permissions. Only devices that pass identity authentication can access the WLAN and communicate.

[0045] Exemplarily, the first radio frequency antenna of the wireless access point is used to implement wireless communication.

[0046] Exemplarily, since the wireless access point has permission to access the wireless LAN, the wireless access point can access the wireless LAN, so a wireless connection is established between the LAN terminal device and the wireless access point, and various LAN terminal devices are connected to the wireless LAN.

[0047] For example, a wireless LAN operates according to a corresponding protocol. Only data that complies with the protocol can be transmitted within the WLAN and received by the mobile convergence gateway. A wireless access point includes protocol conversion functionality, converting non-standard data sent by LAN terminal devices into standard data to facilitate data transmission within the WLAN.

[0048] Exemplarily, the LAN cloud platform manages data on LAN terminal devices and / or sends instructions to LAN terminal devices. The LAN cloud platform is connected to a wireless LAN. Only after connecting to the wireless LAN can LAN terminal devices communicate wirelessly with the LAN cloud platform. The mobile convergence gateway is used to establish a wireless LAN, enabling both LAN terminal devices and the LAN cloud platform to access the wireless LAN. The cellular modem is used to forward data from LAN terminal devices to the LAN cloud platform, and vice versa.

[0049] Optionally, the cellular modem is connected to a main control chip of the mobile convergence gateway, and the main control chip of the mobile convergence gateway sends an instruction to the cellular modem to control the cellular modem to perform modulation or demodulation.

[0050] For example, the LAN terminal device, wireless access point, and mobile convergence gateway are portable mobile devices. In scenarios where the wireless LAN signal quality is poor, the LAN terminal device can be brought as close as possible to the wireless access point and mobile convergence gateway that implement wireless LAN transmission, thereby ensuring that the LAN terminal device is within the coverage area of ​​the wireless LAN and improving communication quality.

[0051] The PWL long-distance transmission networking device provided in the embodiment of the present application includes: a local area network terminal device, a wireless access point, a mobile convergence gateway, and a local area network cloud platform, wherein the local area network terminal device establishes a wireless connection with the wireless access point, and the wireless access point is used to connect the local area network terminal device to the wireless local area network; the wireless access point establishes a wireless connection with the mobile convergence gateway through the first radio frequency antenna of the wireless access point, and the wireless access point includes a protocol encryption chip, and the wireless access point is used to convert the non-standard data of the local area network terminal device into standard data that complies with the wireless local area network protocol through the protocol encryption chip to realize data forwarding between the local area network terminal device and the mobile convergence gateway; the mobile convergence gateway establishes a wireless connection with the local area network cloud platform, and the mobile convergence gateway includes a cellular modem, and the mobile convergence gateway is used to establish a cellular backhaul link of the wireless local area network through the cellular modem to realize data forwarding between the wireless access point and the local area network cloud platform. In the above scheme, the mobile convergence gateway has the characteristics of integration and miniaturization, and can be quickly deployed in the weak network coverage scenario of the local area network, thereby effectively improving the effective coverage range of the local area network, and further improving the communication quality of the wireless local area network.

[0052] A feasible implementation method is to combine Figure 3 Describe the mobile convergence gateway. Figure 3 This is a schematic diagram of the structure of a mobile convergence gateway provided in an embodiment of the present application. The mobile convergence gateway includes a housing, a small base station, and a mobile gateway. At least a portion of the mobile gateway is located inside the housing, and the mobile gateway establishes a wireless connection with the local area network cloud platform and the small base station. The housing includes a fixed component on the outside. The small base station is connected to the housing via the fixed component, and the small base station establishes a wireless connection with a wireless access point. The small base station is used to establish a cellular backhaul link.

[0053] Exemplarily, the mobile gateway is used to connect the LAN terminal device and the LAN cloud platform via a wireless LAN, and forward data between the LAN terminal device and the LAN cloud platform.

[0054] Exemplarily, the mobile gateway is also used to authenticate LAN terminal devices. By placing a mobile gateway between LAN terminal devices and the LAN cloud platform, terminal devices can be authenticated to prevent confidential data leakage caused by non-LAN terminal devices establishing connections with the LAN cloud platform, thereby improving the security of PWL long-distance transmission networking devices.

[0055] Exemplarily, the fixing component is used to fix the small base station outside the housing so that the user can move the mobile convergence gateway to ensure the stability of the small base station.

[0056] Optionally, part of the structure of the mobile gateway is located inside the shell, or the entire mobile gateway is located inside the shell.

[0057] Optionally, the housing may include a cover. When the mobile gateway is entirely located inside the housing, the cover may be closed to protect the mobile gateway.

[0058] Optionally, the shell includes a buckle inside, which is used to fix the mobile gateway to ensure the stability of the mobile gateway.

[0059] Optionally, the small base station can be a mobile base station such as a 5G small base station or a 4G small base station, so as to expand the signal coverage range of the wireless LAN in scenarios where the wireless LAN signal quality is poor.

[0060] Combined with the scenario example, the small base station and the mobile gateway are indirectly fixed. Users can move the small base station and the mobile gateway to an environment with poor wireless LAN signal quality at the same time, so that the LAN terminal devices can effectively access the wireless LAN.

[0061] In this feasible implementation, the small base station and the mobile gateway are fixed by the housing, which can improve the portability of the small base station and the mobile gateway, thereby improving the communication quality of the wireless local area network.

[0062] A feasible implementation method is to combine Figure 4 Describe small base stations. Figure 4 A schematic diagram of the structure of a small base station provided in an embodiment of the present application. The small base station includes a control chip and a power amplifier, wherein the control chip establishes a connection with the power amplifier and is configured to send a first control instruction to the power amplifier based on the link status of the cellular backhaul link, so that the power amplifier adjusts the signal power of the small base station; the power amplifier establishes a wireless connection with a mobile gateway and a wireless access point and is configured to send data to the mobile gateway and the wireless access point.

[0063] Exemplarily, the control chip is used to manage the small base station and send instructions to multiple components of the small base station. The first control instruction is used to instruct the power amplifier to adjust the signal of the small base station to match the cellular backhaul link so that the wireless access point and the mobile gateway can effectively receive the signal of the small base station.

[0064] Combined with the scenario example, if the link status of the cellular backhaul link is poor, the power amplifier is instructed to increase the signal power of the small base station so that the wireless access point and the mobile gateway can effectively receive the signal of the small base station, thereby enabling data to be effectively transmitted.

[0065] In this feasible implementation, by providing a control chip and a power amplifier in the small base station, the signal power of the small base station can be adjusted to match the link status, thereby improving the reliability of data transmission.

[0066] A feasible implementation method is to combine Figure 5 Describe small base stations. Figure 5 A schematic diagram of the structure of a small base station provided in an embodiment of the present application. The small base station also includes a reconfigurable smart surface, wherein a control chip is connected to the reconfigurable smart surface and is configured to send a second control instruction to the reconfigurable smart surface based on location information, so that the reconfigurable smart surface adjusts the network coverage of the wireless local area network.

[0067] For example, reconfigurable smart surfaces are used to improve the communication quality of wireless local area networks by dynamically controlling the electromagnetic wave propagation environment. Reconfigurable smart surfaces achieve this by dynamically adjusting the reflection direction, phase, and amplitude of electromagnetic waves through a planar array composed of a large number of programmable cells.

[0068] In this scenario example, if the current network coverage of the small base station is less than or equal to the first range threshold, the control chip instructs the reconfigurable smart surface to increase the network coverage of the wireless local area network to enable effective communication of the terminal device. If the current network coverage of the small base station is greater than the second range threshold, the control chip instructs the reconfigurable smart surface to decrease the network coverage of the wireless local area network to reduce the energy consumption of the small base station.

[0069] In this feasible implementation, by setting up a reconfigurable smart surface in the small base station, the network coverage of the wireless local area network can be dynamically adjusted, thereby improving the reliability of data transmission.

[0070] A feasible implementation method is to combine Figure 6 Describe the mobile gateway. Figure 6A schematic diagram of the structure of a mobile gateway provided in an embodiment of the present application. The mobile gateway includes a local area network card and a verification device. The local area network card establishes a wireless connection with the small base station and the local area network cloud platform, and is used to forward data between the small base station and the local area network cloud platform. The verification device establishes a wireless connection with the small base station, and is used to determine the device information of the local area network terminal device based on standard data and authenticate the device information through an allow list mechanism.

[0071] Exemplarily, the mobile gateway includes at least two functions: data forwarding and identity authentication. The data forwarding function enables data transmission between the small cell and the LAN cloud platform. The identity authentication function authenticates terminal devices accessing the wireless LAN to prevent non-LAN devices from accessing confidential data in the LAN cloud platform.

[0072] Optionally, when each terminal device sends data to the verification device, the verification device records the terminal device's device information, authenticates the terminal device based on the device information, and stores the device information in an allowed list after successful authentication. Subsequent verification can be performed directly on the allowed list to determine whether the terminal device has passed authentication.

[0073] Combined with the scenario example, confidential data is stored in the LAN cloud platform, and non-LAN terminal devices are isolated through authentication processing by the mobile gateway to prevent non-LAN terminal devices from obtaining confidential data.

[0074] In this feasible implementation, through the LAN network card and verification device, it can ensure that the LAN terminal devices can normally access the LAN cloud platform and isolate non-LAN terminal devices, thereby improving the communication security of the wireless LAN.

[0075] In a feasible implementation, the mobile convergence gateway further includes a heat dissipation device, wherein the heat dissipation device is installed inside the housing and is used to dissipate heat for the mobile convergence gateway.

[0076] For example, the housing may protect the equipment inside the housing, and the equipment inside the housing may generate heat during operation.

[0077] Optionally, the shell includes a heat dissipation channel, which is connected to the heat dissipation device. The heat dissipation channel communicates the inside and outside of the shell to dissipate heat generated by the device inside the shell.

[0078] In this scenario, if the temperature of the device inside the housing is too high, the device needs to be frequency-reduced or suspended. Heat dissipation through a heat dissipation device allows the mobile convergence gateway to continue operating, thereby allowing LAN terminal devices to maintain access to the wireless LAN.

[0079] In this feasible implementation, the heat dissipation device can be used to effectively dissipate heat for the devices in the mobile convergence gateway, thereby improving the stability of the mobile convergence gateway.

[0080] In a feasible implementation, the mobile convergence gateway further includes a shock absorbing device, wherein the shock absorbing device is installed inside the housing and connected to the mobile gateway, and is used to reduce vibration of the mobile gateway.

[0081] Exemplarily, the shock absorbing device is used to reduce the impact of the movement of the mobile convergence gateway on the mobile gateway.

[0082] As explained in this scenario example, the mobile convergence gateway is mobile and can be moved closer to LAN terminals as needed, enabling them to effectively access the wireless LAN. During movement, the mobile convergence gateway will inevitably experience vibration, which can affect communication and cause wear and tear. Shock absorbers can mitigate this vibration.

[0083] In this feasible implementation, the shaking of the mobile gateway is reduced by the shock-absorbing device, thereby improving the communication reliability of the mobile convergence gateway.

[0084] A feasible implementation method is to combine Figure 7 Describes the wireless adapter. Figure 7 The PWL long-distance transmission networking device also includes a wireless adapter, wherein the wireless adapter is connected to a local area network terminal device; the wireless adapter establishes a wireless connection with a wireless access point via a second radio frequency antenna of the wireless adapter.

[0085] For example, for a local area network terminal device that does not have a wireless communication function, the wireless communication function can be expanded through a wireless adapter.

[0086] Optionally, the wireless adapter can be installed on the LAN terminal device through embedded installation or USB installation, and the wireless adapter can be used to receive and send data instead of the LAN terminal device to achieve extended wireless communication functions.

[0087] In this feasible implementation, by extending the wireless communication function through the wireless adapter, multiple devices can be connected to the wireless local area network, thereby improving the versatility of local area network communication.

[0088] In a feasible implementation, the wireless adapter includes an encryption chip, wherein the encryption chip is connected to the second radio frequency antenna, and the encryption chip is used to encrypt non-standard data of the local area network terminal device to obtain encrypted data.

[0089] For example, encryption processing is used to encrypt data transmitted by LAN terminal devices, thereby improving the security of LAN communications. The encryption algorithm of the encryption chip corresponds to the decryption algorithm of the LAN cloud platform, so that the LAN platform can accurately perform decryption processing.

[0090] Optionally, the encryption chip can be used for protocol conversion, converting the LAN terminal device protocol into the corresponding protocol of the wireless LAN, so that the data can be accurately transmitted to the LAN cloud platform.

[0091] Optionally, the encryption chip is also used to decrypt the encrypted data received from the LAN cloud platform so that the LAN terminal device can correctly parse the data.

[0092] In this feasible implementation, encryption processing is performed through an encryption chip, which can effectively improve the security of local area network communications.

[0093] A feasible implementation method is to combine Figure 8 Describe the wireless access point. Figure 8 A schematic diagram of the structure of a wireless access point provided in an embodiment of the present application. The wireless access point includes an identity card and a card slot, wherein the identity card is installed in the card slot of the wireless access point and is used by the small base station to authenticate the wireless access point so that the wireless access point can access the cellular backhaul link.

[0094] Exemplarily, the identity card corresponds to the protocol of the small base station.

[0095] Exemplarily, the ID card is a wireless LAN-specific ID card. The small cell can authenticate the wireless access point through the ID card, allowing access to the wireless LAN only after the authentication is passed. The wireless access point can identify the cellular backhaul link of the small cell's wireless LAN through the ID card.

[0096] In this scenario, a wireless access point connects to a wireless LAN using an ID card. The wireless access point then establishes a wireless connection with a LAN terminal device, allowing the LAN terminal device to connect to the wireless LAN. A wireless access point can connect to multiple LAN terminals, allowing multiple LAN terminals to connect to the wireless LAN through a single wireless access point equipped with an ID card.

[0097] In this feasible implementation, identity authentication is performed through an identity recognition card, which can isolate public network devices and thus improve the security of wireless LAN communications.
