Referring to fig. 2A, a schematic structural diagram of a wlan access device 200 according to an embodiment of the present disclosure is provided. The wlan access device 200 may be a wireless router or a home wireless gateway, or may be a device such as a wireless modem or an optical fiber gateway, and may be applied to the network system architecture shown in fig. 1.
As shown, wireless lan access device 200 is configured with a processor 210, a memory 220, wireless lan circuitry 230, and a network interface 240. Wireless lan circuit 230 is coupled to antenna 250. The power of the wlan circuitry 230 is adjustable. The processor 210 and the wlan circuit 230 may be powered by a power module (not shown). Specifically, 5V,9V,12V,48V and the like can be used for direct power supply, and 3.3V, 1.5V and the like can also be used for direct power supply by utilizing power sharing in the design of a mainboard.

The wireless lan circuit 230 may also be referred to as a Wi-Fi module, typically an integrated circuit, which may include a wireless network card. The Wi-Fi module has the functions of enabling the wireless network card to work in an Access Point (AP) mode and establishing a Wi-Fi wireless local area network. The Wi-Fi module receives or transmits Wi-Fi signals through the antenna 240.
The network interface 204 may include a receiver to provide a wireless interface for a wireless local area network access device to communicate with one or more networks and/or any suitable device, and the network interface 204 may also be an ethernet interface. The network interface 204 may include any suitable hardware and/or firmware. The network interface 204 may include multiple antennas to provide a multiple-input multiple-output wireless interface. In one embodiment, the network interface 204 may include a wide area network interface (WLAN interface) and a local area network interface (LAN interface).
The processor 210 is electrically connected to the wireless lan circuit 230. The term "electrically connected" means directly connected or connected through one or more intervening components or circuits. In some embodiments, processor 210 and wireless lan circuit 230 are connected by a bus or a single signal line. For example, the processor 210 is provided with a USB port, and the wlan circuit 230 is externally connected to the USB port, i.e., the wlan circuit 230 and the processor 210 are connected through the USB port. For another example, the wlan circuit 230 and the processor 210 can be connected via a Peripheral Component Interconnect (PCI) interface. For another example, the wlan circuit 230 and the processor 210 may be connected through other interfaces, such as a serial port, or directly through a signal line.
The wlan circuitry 230 may be built into the wlan access device, for example, as shown in fig. 2A. The wireless lan circuit 230 is built into the housing of the wireless lan access device. In another embodiment, the wlan circuit 230 may be externally connected to the wlan access device, as shown in fig. 2B, and the wlan circuit 230 may be connected to the wlan access device 300 through a USB interface or other type of interface, so as to be electrically connected to the processor in the wlan access device.
The processor 210 may be a general-purpose processor, or may be a specific integrated circuit or a Micro-control Unit (MCU, also referred to as a "MCU") that provides operation and control functions to implement the techniques disclosed in the present application. The processor 210 may include cache memory (not shown for simplicity) as well as other memory (e.g., main memory and/or non-volatile memory, such as a hard disk drive or solid state drive). Cache Memory is implemented using Static Random Access Memory (SRAM), main Memory is implemented using Dynamic Random Access Memory (DRAM), and non-volatile Memory is implemented using flash Memory or one or more disk drives.
The wlan circuit 230 may be a specific integrated circuit capable of performing rf transceiving processing. Wireless lan circuitry 230 may include cache memory (not shown for simplicity) as well as other memory (e.g., main memory and/or non-volatile memory, such as a hard disk drive or solid state drive). In some embodiments, the cache memory is implemented using SRAM, the main memory is implemented using DRAM, and the non-volatile memory is implemented using flash memory or one or more disk drives.
Wireless local area network circuitry 230 may have a power amplifier built in or between wireless local area network circuitry 230 and antenna 250 (not shown in fig. 2 for simplicity). The power amplifier is configured to amplify the power of the wireless signal output by the wireless lan circuit 230 and output the amplified wireless signal to an antenna for transmission.
The processing form of the antenna 250 may be, but is not limited to, a built-in Printed Circuit Board (PCB) onboard antenna or a ceramic antenna, a copper wire antenna or a mixture of the above, or may be, through the specification of a common detachable antenna joint such as an I-PEX joint SMA joint, an antenna extension line is connected, and then the antenna is externally arranged to obtain a better effect.
It should be noted that, although one processor is configured in the wireless lan access device shown in fig. 2A and 2B for simplicity, the number of configurable processors in the wireless lan access device may be multiple.

It should be understood that the scope of the embodiments of the present application is not limited to the embodiments shown in fig. 2A and 2B, and the scope of the embodiments of the present application should include the components shown in fig. 2A and 2B and various modifications thereof.
The wlan access device 200 and the wlan access device 300 may operate in a first operation mode or a second operation mode. Of course, the wlan access device can also operate in other operating modes. The first working mode is an open mode, and the wireless local area network access equipment in the open mode does not need to provide an access password for the terminal when performing network access on the terminal. The second working mode is a non-open mode, and when the wireless local area network access equipment in the non-open mode performs network access on the terminal, the wireless local area network access equipment needs to provide an access password for the terminal and verify the access password provided by the terminal. The first working mode corresponds to a first transmission power or a first transmission power range, the second working mode corresponds to a second transmission power or a second transmission power range, wherein the first transmission power is smaller than the second transmission power, or any value in the first transmission power range is smaller than any value in the second transmission power range. That is, in one example, when the wireless local area network access device is in the first operating mode, the transmission power of the wireless signal sent by the wireless local area network circuit (Wi-Fi module) is the first transmission power, and when the wireless local area network access device is in the second operating mode, the transmission power of the wireless signal sent by the wireless local area network circuit (Wi-Fi module) is the second transmission power; in another example, when the wireless lan access device is in the first operating mode, the wireless signal transmission power sent by the wireless lan circuit (Wi-Fi module) is any value within the first transmission power range, and when the wireless lan access device is in the second operating mode, the wireless signal transmission power sent by the wireless lan circuit (Wi-Fi module) is any value within the second transmission power range.
In a specific implementation, a set value may be preset, when the wlan access device is switched from the second operating mode to the first operating mode, the signal transmission power of the wlan access device is reduced to a first transmission power, where the first transmission power is smaller than the set value, and when the wlan access device is switched from the second operating mode to the first operating mode, the signal transmission power of the wlan access device is increased to a second transmission power, where the second transmission power is equal to the set value or greater than the set value.
In general, the second transmission power is preset and fixed, and may represent the maximum coverage area of the wlan access device. The first transmitting power can be preset and fixed, and can be set by a user according to needs, but is not larger than the second transmitting power. For example, a user setting option may be provided in a configuration interface of the wlan access device, through which the user may select or input the magnitude of the first transmission power, which may be characterized by a radius of coverage in the implementation.
The wlan access device 200 or the wlan access device 300 may switch to the first operating mode according to the first access instruction and switch to the second operating mode according to the second access instruction. The first access instruction and the second access instruction can be sent out by a user according to needs. The following exemplifies several transmission modes of the first access instruction or the second access instruction:
mode 1
In the mode 1, the wireless lan access device is provided with a key electrically connected to the processor, and the user can press or touch or otherwise operate the key to issue the first access instruction and/or the second access instruction. The key can be arranged on the front panel or the rear panel of the wireless local area network access equipment so as to facilitate the operation of a user. Further, an indicator light may be further disposed on the wlan access device for indicating the current operating mode, such as indicating whether the current operating mode is the first operating mode or the second operating mode through the indicator light.
The number of the keys may be one or more. If the number of the keys is multiple, one key can send out a first access instruction when being triggered, and the other key can send out a second access instruction when being triggered. If the number of the keys is one, the key may have 2 limit states (a first limit state and a second limit state), for example, the key state corresponding to the first limit state is that the key is pressed, and the key state corresponding to the second limit state is that the key is lifted. When the key is triggered and then is in the first limit state, a first access instruction can be sent out, and when the key is triggered and then is in the second limit state, a second access instruction can be sent out. For example, when the button is pressed and kept pressed, the wlan access device switches to the first operation mode and keeps the operation mode, and when the button is lifted, the wlan access device switches to the second operation mode. In another example, if the number of the keys is one, the switching between the first access instruction and the second access instruction may be performed. The processor may also determine the instruction sent when the key is triggered according to the current working mode of the wlan access device, for example, when the key is triggered, the processor determines that the instruction sent when the key is triggered is the second access instruction when the processor determines that the current wlan access device is in the first working mode, otherwise, when the key is triggered, the processor determines that the instruction sent when the key is triggered is the first access instruction when the processor determines that the current wlan access device is in the second working mode.
Mode 2
In the mode 2, the configuration user interface of the wireless lan access device is provided with a function key for triggering the first access instruction and a function key for triggering the second access instruction, and when a user needs to switch the working mode of the wireless lan access device, the user can first access the configuration user interface of the wireless lan access device and send the first access instruction or the second access instruction according to the function key provided in the user interface.
The above mode 1 and mode 2 are merely exemplary examples. In other embodiments, other ways of triggering the first access command and the second access command, such as voice control or wireless remote control, may also be supported. Of course, the wlan access device provided in the embodiments of the present application can support one triggering method, and can also support multiple triggering methods,
it should be noted that, in the above example, the first access instruction is used to trigger the wlan access device to enter the first operating mode, and the second access instruction is used to trigger the wlan access device to enter the second operating mode. In another example, the wlan access device does not define a first operating mode and a second operating mode, in which case the first access instruction may trigger the wlan access device to decrease the transmission power of the wireless signal and instruct the wlan access device to cancel the access authentication of the terminal, the decreased transmission power of the wireless signal is lower than a set value, the second access instruction may trigger the wlan access device to increase the transmission power of the wireless signal and instruct the wlan access device to resume the access authentication of the terminal, and the increased transmission power of the wireless signal is not lower than the set value.
Based on the above-mentioned wireless local area network access device shown in fig. 2A or fig. 2B, fig. 3 exemplarily shows a network access procedure provided by the embodiment of the present application.
When it is necessary to make the wlan access device reduce the transmission power of the wireless signal, so as to make the terminal closer to the wlan access device access the network in an encryption-free manner, the first access instruction may be submitted to the processor in the wlan access device in the manner described in the foregoing embodiment, so that the processor in the wlan access device executes the following process:
in S310, according to the first access instruction, reducing the transmission power of the wireless signal, where the reduced transmission power of the wireless signal is lower than a set value; the first access instruction is used for instructing the wireless access equipment to cancel access authentication of a terminal.
In some embodiments, the wlan access device may switch to a first operation mode according to the first access instruction, and in the first operation mode, the transmission power of the wireless signal is reduced to be lower than the set value. For example, when the wireless local area network access device operates in the second operating mode, if a first access instruction is received, the second operating mode is switched to the first operating mode, the transmission power of the wireless signal (Wi-Fi signal) is reduced from the second power to the first transmission power, and the first transmission power is lower than the set value.
In S320, after the transmission power of the wireless signal of the wlan access device is reduced, the terminal to be accessed within the coverage of the wireless signal may receive the wireless signal sent by the wlan access device, and may send a network access request to the wlan access device according to a Service Set Identifier (SSID) carried therein, where the SSID of the wlan access device and the Identifier information of the terminal may be carried. Because the transmission power of the wireless local area network access equipment is reduced, the coverage of wireless signals is reduced, the wireless signals transmitted by the wireless local area network access equipment can only be found by terminals in the adjacent space, and the remote terminals cannot detect the wireless local area network access equipment. After a processor in the wireless local area network access equipment receives a network access request sent by the terminal, if the SSID carried in the wireless local area network access equipment is confirmed to be the SSID of the wireless local area network access equipment, the terminal is accessed into the network, and the authority (such as Internet access authority) is released according to the situation. Further, the wlan access device may add the identification information of the terminal to a list (i.e., white list) of authorized terminals of the wlan access device. Optionally, the identification information of the terminal may include one or any combination of the following information: a physical address of the terminal, and fingerprint information of the terminal, where the physical address of the terminal may include a Media Access Control (MAC) address.
Optionally, after the terminal is accessed to the network in an encryption-free manner, when the normal operation of the wlan access device needs to be resumed, the second access instruction may be submitted to the processor in the wlan access device in the manner described in the foregoing embodiment, so that the processor in the wlan access device executes the following process: in S330, increasing the transmission power of the wireless signal according to the second access instruction, where the increased transmission power of the wireless signal is not lower than the set value; the second access instruction is used for instructing the wireless access equipment to recover the access verification of the terminal.
In some embodiments, the wlan access device switches to the second operating mode according to the second access instruction, and recovers the transmission power of the wireless signal. For example, when the wireless local area network access device operates in the first operating mode, if a second access instruction is received, the wireless local area network access device switches from the first operating mode to the second operating mode, the transmission power of the wireless signal (Wi-Fi signal) is increased from the first power to the second transmission power, and the second transmission power is equal to or greater than the set value.
After receiving the second access instruction, the terminal can continue to use the network service and the data transmission service provided by the wireless local area network access device because the identification information of the terminal is already added into the authorized terminal list.
When the wireless local area network access equipment is in the second working mode, if a network access request sent by a terminal is received, a processor of the wireless local area network access equipment judges whether an SSID carried in the network access request is the SSID of the wireless local area network access equipment, if so, the terminal is requested to send an access password, after the access password sent by the terminal is received, the access password is verified, if the access password passes the verification, the terminal is accessed to the network, otherwise, the terminal is refused to be accessed to the network.
In the above flow, optionally, the processor in the wlan access device may control the transmission power of the wireless signal by:
mode 1
The processor of the wireless local area network access device controls the power module to change the current or voltage provided to the wireless local area network circuit so as to achieve the purpose of changing the transmitting power of the wireless signal.
Mode 2
The processor of the wireless local area network access device controls the parameters of the power amplifier in the wireless local area network circuit or controls the parameters of the power amplifier arranged between the wireless local area network circuit and the antenna so as to achieve the purpose of changing the transmitting power of the wireless signal.
As can be seen from the above description, in the above embodiments of the present application, the wireless local area network access device reduces the transmission power of the wireless signal according to the first access instruction, and the wireless access device, after reducing the transmission power of the wireless signal, accesses the terminal to the network according to the wireless network access request sent by the terminal within the coverage of the wireless signal. The first access instruction is used for instructing the wireless access device to cancel the access authentication of the terminal, so that the coverage of the wireless signal is reduced by reducing the transmission power of the wireless signal, and when the terminal in the smaller coverage sends a network access request to the wireless local area network access device, the wireless local area network access device can cancel the access authentication of the terminal and access the terminal to the network. When the embodiment of the application is used in practical application, when a trusted terminal needs to be accessed, the distance between the terminal and the wireless local area network access device can be shortened, the wireless local area network access device reduces the transmission power of signals through the first access instruction, and the access verification of the terminal is cancelled, so that the trusted terminal can be accessed to the network under the condition that the access password does not need to be provided by the trusted terminal, and the operation of accessing the network by the terminal through the wireless local area network access device is simplified under the condition of considering security.
The following describes a specific implementation process of the embodiment of the present application with reference to a specific scenario.
Scene one
In the scene, the wireless local area network access device is specifically a wireless router, and the Wi-Fi module is arranged inside a shell of the wireless router. In the first working mode, the coverage range of the Wi-Fi signals of the wireless router is a range with a radius of 5 meters, and in the second working mode, the coverage range of the Wi-Fi signals of the wireless router is a range with a radius of 50 meters.
The wireless router is currently operating in the second mode of operation. When a user needs to access the smart phone to the wireless local area network, the smart phone can be moved to a range of 5 meters away from the wireless router, and a key arranged on a shell of the wireless router is pressed to trigger a first access instruction. And the wireless router is switched to a first working mode according to the first access instruction, and the Wi-Fi signal transmitting power is reduced in the first working mode, so that the coverage range of the Wi-Fi signal is reduced to a range with a radius of 5 meters. The smart phone to be accessed into the network is within the coverage range of the Wi-Fi signal, so that the Wi-Fi signal which is sent by the wireless router and carries the SSID of the wireless router can be received. The user can send a network access request by operating the smart phone, wherein the network access request carries the SSID of the wireless router and the MAC address of the smart phone. And after receiving the network access request, the wireless router adds the MAC address of the smart phone into an authorized user list.
The user presses a key provided on the wireless router housing to trigger the second access instruction. And the wireless router is switched to a second working mode according to the instruction, and in the second working mode, the transmitting power of the Wi-Fi signal of the wireless router is increased, and the coverage area of the Wi-Fi signal is increased to a range with the radius of 50 meters.
When the wireless router works in the second working mode, if a terminal sends a network access request, a correct network access password needs to be provided to be accessed to the network.
The above scenario is applicable to wireless routers in the home. When a guest visits, the mobile phone of the guest can be regarded as a trusted terminal, and the mobile phone of the guest is accessed to the network in an encryption-free mode through the mode, so that the complexity of network access can be simplified on the premise of ensuring the security.
Scene two
In this scenario, the wireless lan access device is specifically a wireless router, and a Wi-Fi module of the wireless router is disposed inside a housing of the wireless router. In the first working mode, the coverage range of the Wi-Fi signals of the wireless router is a range with a radius of 5 meters, and in the second working mode, the coverage range of the Wi-Fi signals of the wireless router is a range with a radius of 50 meters.
The wireless router is currently operating in the second mode of operation. When a user needs to access the intelligent air conditioner to the wireless local area network, the wireless router can be moved to a range 5 meters away from the intelligent air conditioner, and a key arranged on a shell of the wireless router is pressed to trigger a first access instruction. And the wireless router is switched to a first working mode according to the first access instruction, and the Wi-Fi signal transmitting power is reduced in the first working mode, so that the coverage range of the Wi-Fi signal is reduced to a range with a radius of 5 meters. Because the intelligent air conditioner to be accessed into the network is in the coverage range of the Wi-Fi signal, the Wi-Fi signal which is sent by the wireless router and carries the SSID of the wireless router can be received. The intelligent air conditioner can send a network access request after detecting the Wi-Fi signal sent by the wireless router, wherein the network access request carries the SSID of the wireless router and the MAC address of the intelligent air conditioner. And after receiving the network access request, the wireless router adds the MAC address of the intelligent air conditioner into an authorized user list.
And the user restores the wireless router to the original placement position and presses down a key arranged on the shell of the wireless router to trigger a second access instruction. And the wireless router is switched to a second working mode according to the instruction, and in the second working mode, the transmitting power of the Wi-Fi signal of the wireless router is increased, and the coverage area of the Wi-Fi signal is increased to a range with the radius of 50 meters.
The above scenario is applicable to wireless routers in the home. Under the condition that some terminals (such as smart home devices) are inconvenient to move, the terminals can be regarded as trusted terminals, and the terminals are accessed to the network in an encryption-free mode through the method, so that the complexity of network access is simplified on the premise of ensuring the security. In addition, the smart home devices are not usually provided with an input device, and if the smart home devices access the network in an encryption mode, the access passwords cannot be directly input and sent to the wireless router.
Scene three
In the scene, the wireless local area network access device is specifically a wireless router, a Wi-Fi module of the wireless router is arranged outside a shell of the wireless router, and the Wi-Fi module is connected with a USB interface of the wireless router through a USB cable. In the first working mode, the coverage range of the Wi-Fi signals of the wireless router is a range with a radius of 5 meters, and in the second working mode, the coverage range of the Wi-Fi signals of the wireless router is a range with a radius of 50 meters.
The user presses a key provided on the wireless router housing to trigger the second access instruction. And the wireless router is switched to a second working mode according to the instruction, and in the second working mode, the transmitting power of the Wi-Fi signal of the wireless router is increased, and the coverage area of the Wi-Fi signal is increased to a range with the radius of 50 meters.
The above scenario is applicable to wireless routers in the home. Under the condition that some terminals (such as smart home devices) are inconvenient to move, the terminals can be regarded as trusted terminals, and the terminals are accessed to the network in an encryption-free mode through the method, so that the complexity of network access is simplified on the premise of ensuring the security.
