[0002] With the widespread application of wireless network technology, the performance and stability of WiFi networks are crucial for individual and enterprise users.

Furthermore, after the WIFI chip is installed in a wireless network device, it is impossible to perform fixed-frequency testing, which makes it difficult to understand the network status in real time and to detect potential problems in a timely manner during operation.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings are used to distinguish different objects, not to describe a particular order.

[0024] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, this utility model discloses a WIFI network device with a fixed-frequency testing function, including a main control module containing fixed-frequency testing software. It also includes a power module, a function control module, and a storage module, all connected to the main control module. Furthermore, it includes a WIFI module and a switch module, wherein the switch module is positioned between the power module and the WIFI module. The control terminal of the switch module is connected to the main control module, and the switch module is used to control the WIFI module to enter either a fixed-frequency mode or a normal operating mode. This example also includes a reset button for resetting the main control module system and a debugging interface for debugging the main control module.

[0027] In this example, the main control module, AM8269D, is responsible for overall control, coordinating the work of various modules, judging button operations, and controlling the start and end of the fixed-frequency test. The switch module acquires button information and transmits it to the main control module to control the WIFI module to enter fixed-frequency mode or normal operation mode. The WIFI module executes 2.4G or 5G fixed-frequency operation according to the instructions of the main control module. The power module is responsible for supplying power to the main control module. This example also includes a USB module, which can be used as an online firmware upgrade port. The power module in this example includes a TYPEC interface for power output to the entire network device. Preferably, the TYPEC interface and the USB module in this example use the same TYPEC interface to reduce product cost and operational complexity.

[0028] In this example, the WIFI network device is a device equipped with a WIFI module, enabling the product to receive and operate WIFI signals. This could be a screen mirroring device, a screen projector, a smart TV device, etc.

[0029] like Figure 1 As shown in the illustration, in one embodiment of this utility model, the WIFI network device is an HDMI screen mirroring device. The functional control module is an HDMI interface module that outputs HDMI signals to the display device. The HDMI interface module is equipped with an HDMI detection unit, which detects whether a display device is connected to the HDMI interface and feeds back the HDMI status to the main control module. In this example, the main control module uses the AM8269D wireless screen mirroring main control chip. The display device in this example can be a monitor, portable screen, or television, etc.

[0030] By setting up an HDMI detection unit, the adverse effects of fixed-frequency testing on normal user operation can be effectively avoided, thus improving the user experience. When a user is detected using a display device, a command can be issued to control the WIFI module to turn off the fixed-frequency mode and enter the normal working mode.

[0031] In this example, the storage module is a non-volatile memory (SPI Nor) using the SPI (Serial Peripheral Interface) communication interface. The main control module communicates with the storage module by setting the DDR2 pin and uses a reset button for resetting the main control module.

[0033] like Figure 4 and Figure 5As shown, the power module in this example includes a power output interface, a soft-start unit, a switching unit, a power indicator unit, and one or more power conversion units. The output terminal of the power output interface is connected to the input terminal of the soft-start unit, the output terminal of the soft-start unit is connected to the input terminal of the switching unit, and the output terminal of the switching unit is connected to the power indicator unit and the power conversion unit respectively. The power conversion unit is used to convert the output voltage of the switching unit into different operating voltages and supply them to the back-end circuit.

[0034] This example soft-start unit includes a switch Q1, capacitors C34-C36, capacitor C27, a TVS diode, resistors R19 and R20. The gate of the switch Q1 is connected to one end of capacitor C27 and one end of resistor R19, respectively. The other end of resistor R19 is grounded. The other end of capacitor C27 is connected to the output terminal of the power output interface. The source of the switch Q1 is connected to one end of capacitors C34 and C35 and one end of resistor R20, respectively. The other end of resistor R20 and the negative terminal of the TVS diode are connected to the output terminal of the power output interface, respectively. The other ends of capacitors C34 and C35 and the positive terminal of the TVS diode are grounded, respectively. The drain of the switch Q1 outputs the first operating voltage. One end of capacitor C36 is grounded, and the other end is connected to the drain output terminal of the switch Q1.

[0035] This example switching unit includes a transistor Q3, a switching transistor Q2, and a Zener diode D2. The base of transistor Q3 is connected to a first operating voltage via resistors R27 and R25. The cathode of the Zener diode is connected between resistors R27 and R25, and its anode is grounded. The collector of transistor Q3 is connected to the gate of switching transistor Q2. The source of switching transistor Q2 is connected to the first operating voltage, and its drain outputs a second operating voltage via a ferrite bead FB2. The FB bead is mainly used in power supply filtering circuits and noise filtering circuits for signal cables.

[0036] like Figure 6 As shown, this example uses a USB high-speed analog switch chip U7. Pin 1 of the USB high-speed analog switch chip U7 is connected to the switching power supply, pin 2 is connected to the physical button for receiving user operation signals, pins 3 and 4 are connected to the main control module, pins 6-7 are connected to the power supply module, and pins 8-9 are connected to the communication pins of the WIFI module. This switch module enables the switching between the fixed-frequency and normal modes of the WIFI module. Of course, this example could also use a DIP switch or other switching devices with two or more states.

[0037] As can be seen from the above, this utility model innovatively installs the WIFI module in the WIFI network device for fixed-frequency testing, making it closer to the actual application scenario and the test more accurate.

[0038] In addition, by making hardware improvements to the WIFI network equipment, it is possible to support real-time fixed-frequency testing. During user operation, the fixed-frequency test can be triggered by the switch module, thereby helping users to understand the network status in real time, discover potential problems in a timely manner, and improve the stability and reliability of the working performance.
