Dynamic Wireless Channel Grouping for Network Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless network systems fail to adequately support client devices and provide poor network coverage due to equal channel assignment assumptions, leading to inadequate support for certain devices and increased interference.
Innovation Solution
A method for dynamically categorizing wireless channels based on priorities and assigning them to access points to ensure well-balanced, wide coverage by grouping channels according to factors like interference, client device capabilities, and regulatory requirements, and then distributing these groups across access points to maximize coverage and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channels are assigned equally to all access points, then the system is simple to manage, but network coverage becomes poor and certain client devices are inadequately supported
Solution Approach 1:
The patent changes the channel assignment parameters from uniform distribution to priority-based distribution. Channels are categorized into different priority groups (first priority, second priority, third priority) based on client device capabilities and network requirements. Access points are assigned channels from different priority groups according to their coverage areas and client device compositions, optimizing network coverage quality for diverse devices.
Solution Approach 2:
The patent implements local quality by assigning different channel priorities to different access points based on their specific locations and client device environments. Each access point neighborhood is analyzed to determine appropriate channel priority assignments, ensuring that channels are optimized for the local client device population rather than applying a uniform approach across the entire network.
2Reliability
If traditional equal channel assignment is used, then the system is easy to implement, but interference between channels increases
Solution Approach 1:
The patent changes the channel assignment strategy from equal distribution to priority-based distribution. By categorizing channels into different priority groups and assigning them selectively to access points based on client device capabilities, the system reduces channel interference. High-priority channels are assigned to access points serving devices that require them, while low-priority channels are assigned to other access points, minimizing overlapping and interference.
3Adaptability or versatility
If channels are assigned without considering client device capabilities, then the assignment process is simple, but support for certain client devices becomes inadequate
Solution Approach 1:
The patent introduces priority group parameters based on client device capabilities. Channels are divided into first priority, second priority, and third priority groups according to the specific requirements of different client devices. This parameter-based classification enables the system to adapt to diverse client device capabilities while maintaining a structured assignment process.
Solution Approach 2:
The patent performs preliminary analysis of client device capabilities and channel characteristics before assignment. The system pre-categorizes channels into priority groups and pre-identifies the client device composition in each access point neighborhood, allowing for optimized channel assignment that adapts to specific device requirements without requiring complex real-time adjustments.

AI summary
System and methods are provided for dynamically assigning wireless channels to priority groups based on characteristics of the channels, the environment in which the channels will be used, regulatory requirements, and/or capabilities of client devices. Thereafter, channels may be intelligently assigned to access points to achieve one or more goals. For example, wireless channels may be assigned to access points to ensure balanced coverage throughout the network system for client devices of each type/capability, to minimize effects of wireless interference in the network system, to increase fault tolerance in the network system, and/or to generally improve the coverage and quality of connections in the network system.
