Multi-Chipset Network Scanning for Collocated 6 GHz Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network scanning methods often overlook viable 6 GHz connections in favor of 2.4 GHz and 5 GHz connections, leading to suboptimal network selection due to sequential scanning that prioritizes lower frequency bands.
Innovation Solution
Implement network scanning operations that first search for suitable networks in 2.4 GHz and/or 5 GHz bands and subsequently scan for collocated 6 GHz connections, prioritizing 6 GHz APs after identifying a suitable network in lower frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sequential network scanning prioritizes 2.4 GHz and 5 GHz bands, then compatibility and coverage are improved, but network speed and performance deteriorate due to overlooking 6 GHz connections
Solution Approach 1:
The patent performs preliminary network scanning in the 6 GHz band before finalizing network selection, ensuring high-speed connections are identified early in the process. This preliminary action allows the system to prioritize 6 GHz APs while maintaining compatibility with lower frequency bands, resolving the contradiction between reliability and speed.
2Ease of operation
If conventional sequential scanning is used, then scanning simplicity is maintained, but network selection optimality deteriorates due to fixed priority ordering
Solution Approach 1:
The patent introduces dynamic network selection criteria that adapt based on detected conditions. Instead of fixed priority ordering, the system dynamically evaluates multiple factors including signal strength, distance to AP, and network load to determine optimal connections. This dynamic approach maintains operational simplicity while significantly improving selection precision.
3Speed
If 6 GHz band scanning is added to conventional scanning, then network performance is improved, but scanning complexity increases
Solution Approach 1:
The patent segments the network scanning process into distinct phases: initial scanning in 2.4 GHz and 5 GHz bands, followed by targeted 6 GHz band scanning for collocated APs. This segmentation allows the system to manage complexity by processing different frequency bands in organized stages rather than simultaneously, improving performance while controlling complexity.
4Speed
If collocated 6 GHz APs are prioritized, then network speed is improved, but connection flexibility deteriorates due to preference for higher frequency band
Solution Approach 1:
The patent applies local quality by making 6 GHz APs preferred only when specific local conditions are met (collocated with 2.4 GHz or 5 GHz APs, sufficient signal strength). The preference is not absolute but contextual, allowing the system to adapt to local environment characteristics. This resolves the contradiction by making speed optimization conditional rather than rigid.

AI summary
Technologies related to network scanning are described. A first network scan is performed within a first frequency band. A network is selected based on the first network scan. Based on the selection of the network, a second network scan is performed within a second frequency band different from the first frequency band.
