WLAN Frequency Band Switching via Command Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing WLAN network control methods for frequency band selection in vehicles are unreliable and can temporarily reduce performance, as they depend on environmental conditions and device implementations, making it difficult to switch between frequency bands without disrupting connectivity.
Innovation Solution
The implementation of an apparatus and method that allows reliable frequency band switching between 2.4 GHz and 5 GHz bands in WLAN networks by using additional commands and maintaining authentication and DHCP procedures across band changes, ensuring seamless media access control transitions and avoiding disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing WLAN network control methods are used for frequency band selection, then the system can operate with standard protocols, but the frequency band switching becomes unreliable and performance is temporarily reduced
Solution Approach 1:
The patent applies preliminary action by maintaining authentication and DHCP procedures in advance before frequency band switching occurs. The system prepares and preserves these critical network layer procedures so they remain valid during and after the band transition, preventing connectivity disruptions and ensuring reliable switching without performance degradation.
2Productivity
If frequency band switching is implemented to improve network performance, then connectivity can be optimized, but disconnection and reliability issues occur
Solution Approach 1:
The patent implements continuity of useful action by ensuring that authentication and DHCP procedures continue uninterrupted during frequency band switching. The system maintains the validity of these network layer procedures across the transition, allowing seamless band switching without disconnection, thus preserving both performance optimization and connection stability.
3Reliability
If additional commands are used for frequency band switching, then switching reliability improves, but device complexity increases
Solution Approach 1:
The patent applies universality by designing additional control commands that serve multiple functions: they initiate frequency band switching, maintain authentication procedures, preserve DHCP operations, and ensure seamless transition all through a unified command structure. This multi-functionality improves switching reliability without proportionally increasing device complexity.
