Dual WiFi Roaming Frequency Band Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a mobile terminal operates in dual WiFi mode, connecting to two different WiFi networks simultaneously, interference between the two networks leads to larger delays, unstable network speeds, and poor transmission performance if they operate in the same frequency band.
Innovation Solution
Implementing an intelligent roaming method for dual WiFi modules, where each module operates in a different frequency band, and restricting one module to roam only within its designated frequency band to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile terminal connects to two different WiFi networks simultaneously in the same frequency band, then the network speed and network delay are improved, but the network transmission performance deteriorates due to interference and time-sharing operation
Solution Approach 1:
The patent segments the frequency spectrum by assigning the first WiFi module to operate in a first frequency band and the second WiFi module to operate in a second frequency band. This frequency band segmentation eliminates interference between the two WiFi modules while allowing both to operate simultaneously, thus maintaining high network speed without sacrificing transmission performance.
Solution Approach 2:
The patent applies local quality by giving each WiFi module a distinct frequency band assignment. The first WiFi module is restricted to the first frequency band while the second WiFi module operates in the second frequency band. This localized frequency allocation ensures that each module operates in its own dedicated spectral environment, preventing mutual interference and maintaining reliable network transmission.
2Adaptability or versatility
If the first WiFi module is allowed to roam freely across frequency bands, then the roaming flexibility is improved, but interference with the second WiFi module increases
Solution Approach 1:
The patent implements local quality by restricting the first WiFi module to roam only within the first frequency band. This targeted roaming restriction allows the module to adapt to different networks within its designated band while preventing it from entering the second frequency band where the second WiFi module operates, thus eliminating harmful interference.
Solution Approach 2:
The patent segments the roaming behavior by frequency band. The first WiFi module is configured with roaming capabilities limited to the first frequency band, while the second WiFi module manages the second frequency band. This segmented approach maintains roaming flexibility within each band while preventing cross-band interference.

AI summary
A WiFi roaming method and device, a mobile terminal, and a storage medium are provided. The method includes the following. When both the first WiFi module and the second WiFi module are in the connected state, the first WiFi module connected with an access point (AP) is controlled to operate at the first frequency band and the second WiFi module connected with an AP is controlled to operate at the second frequency band, where the first frequency band is not overlapped with the second frequency band. The first WiFi module is controlled to be in the first roaming restriction mode to restrict the first WiFi module to roam in the first frequency band. By means of implementations of the present disclosure, network transmission performance of dual WiFi modules can be improved.
