Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single Wi-Fi link is used for data transmission, then the device can maintain simple operation mode, but the data transmission capability and flexibility are limited
Solution Approach 1:
The Wi-Fi communication capability is segmented into two independent links: a first Wi-Fi link operating in station mode and a second Wi-Fi link operating in soft access point mode. Each link operates independently with different frequency bands, allowing the device to simultaneously perform different communication functions (client access and hotspot sharing) without mode switching complexity
Solution Approach 2:
The electronic device is configured to simultaneously support multiple Wi-Fi functions through the dual-link architecture: it can act as both a Wi-Fi client (station mode on first link) and a Wi-Fi hotspot (soft AP mode on second link) at the same time, enabling universal adaptability across different data transmission scenarios
2Productivity
If multiple Wi-Fi links operate on the same frequency band, then the device can simplify frequency management, but data transmission efficiency and simultaneity are reduced
Solution Approach 1:
The solution transitions from single-dimensional frequency management to multi-dimensional operation by assigning different frequency bands (dimensions) to different Wi-Fi links. The first Wi-Fi link operates on a first frequency band while the second Wi-Fi link operates on a second frequency band, enabling simultaneous data transmission without frequency conflicts and improving overall transmission efficiency
3Adaptability or versatility
If the device switches between different Wi-Fi modes, then it can adapt to different network scenarios, but transmission continuity and speed are affected
Solution Approach 1:
By establishing both a station-mode Wi-Fi link and a soft AP-mode Wi-Fi link simultaneously, the device achieves continuous data transmission capability across multiple network scenarios without mode switching interruptions. The dual-link configuration ensures that data transmission continues uninterrupted whether the device is accessing a network or sharing it

AI summary
A method for data transmission and related products are provided. The method is applicable to an electronic device. A first wireless-fidelity (Wi-Fi) link and at least one second Wi-Fi link are established between the electronic device and at least one terminal. The first Wi-Fi link is operable in a station mode and each second Wi-Fi link is operable in a soft AP mode. The method includes the following. Data transmission is performed with the at least one terminal over the first Wi-Fi link and the at least one second Wi-Fi link simultaneously, where a transmission frequency band for data transmission over the first Wi-Fi link is different from a transmission frequency band for data transmission over each of any two links of the at least one second Wi-Fi link.
