Description

Technical Field

[0001] The present invention belongs to the technical field of wireless network communication, and more specifically, particularly relates to a portable WiFi system and device capable of switching networks by pressing a button. Background Art

[0002] In today's digital and mobile era, the convenience and importance of wireless networks are becoming increasingly prominent. As a tool that can provide users with wireless network connections anytime and anywhere, portable WiFi devices have received widespread attention and application.

[0003] However, traditional portable WiFi devices have many limitations and shortcomings in network switching. In the past, portable WiFi switching networks usually depended on the device being connected to the Internet, and the user needed to operate through a specific application (App) or mini-program. Not only that, sometimes it is necessary to connect to the local management background of the device and connect to the device's WiFi network to complete the switch.

[0004] There are many problems with this switching method. First, it has strict requirements on network conditions. If the device itself is not connected to the Internet or the network is unstable, the switching operation cannot be performed. Second, the operation steps are cumbersome and complicated, requiring users to select and confirm in multiple interfaces, which is prone to misoperation. Moreover, due to the reliance on specific software and network environment, the success rate of network switching is often not guaranteed, and switching failures often occur.

[0005] In addition, traditional switching methods perform poorly in some special scenarios, such as in areas without Wi-Fi coverage, places with extremely weak network signals, or when there is an urgent need to quickly switch networks to ensure communication. They cannot meet user needs in a timely and effective manner.

[0006] In summary, the existing portable WiFi network switching technology can no longer meet the user's demand for convenient, efficient and stable network switching. There is an urgent need for an innovative network switching solution that is not restricted by network conditions and is easy to operate.

Compared with the existing technology, it has achieved innovation and breakthroughs in many aspects and has high practical value and market competitiveness.

[0090] In summary, the portable WiFi system and device that can switch networks with a single button has demonstrated significant innovations and advantages in many aspects.

[0091] From the perspective of the system and equipment composition, the carefully selected components work together to form an efficient, stable and powerful whole. The Intel X86 chipset-based motherboard component provides powerful data processing capabilities, and the Realtek 8812BRH network control chip ensures high-quality network connections. Three ESIM cards from different operators with different characteristics and speeds provide users with a variety of choices in various network environments.
