Autonomous WDS Channel Coordination via Master AP
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual configuration of wireless distribution system (WDS) channels in wireless communication systems is cumbersome, error-prone, and costly, and fails to adapt dynamically to changing interference and traffic conditions.
Innovation Solution
A method for autonomous channel coordination in WDS, where a coordinated channel group (CCG) is established with a designated master AP that dynamically changes the WDS channel based on member APs' capabilities and measurements, ensuring connectivity while allowing APs to join, leave, or change channels within the CCG.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration of WDS channels is used, then system setup is simple and controlled, but the process is cumbersome, error-prone, costly and cannot adapt dynamically to changing conditions
Solution Approach 1:
The system enables autonomous channel coordination where APs automatically select and switch WDS channels based on their own measurements of interference and traffic conditions, eliminating the need for manual configuration and ongoing administrative intervention while adapting dynamically to changing environmental conditions
Solution Approach 2:
APs continuously measure channel conditions including interference levels and traffic patterns, use this feedback information to make intelligent decisions about channel selection, and switch channels autonomously when improvements are detected, creating a closed-loop adaptive system
2Adaptability or versatility
If autonomous channel coordination is implemented, then dynamic adaptation to conditions is achieved, but system complexity increases due to coordination protocols and measurements
Solution Approach 1:
The patent combines channel selection, interference measurement, and channel switching functions into a unified autonomous coordination mechanism where APs work together through standardized protocols to collectively optimize the WDS channel configuration, reducing overall system complexity through integration
Solution Approach 2:
The system divides the autonomous coordination process into distinct functional modules: measurement of channel conditions, evaluation of interference and traffic patterns, decision-making for channel selection, and execution of channel switching, allowing each component to be implemented and managed independently
3Reliability
If WDS channel is changed manually, then connectivity can be maintained through administrator control, but the process is time-consuming and cannot keep track of short-term changes
Solution Approach 1:
APs continuously monitor and measure channel conditions in advance, detecting changes in interference and traffic patterns before they significantly impact performance, allowing the system to proactively switch to optimal channels before connectivity degradation occurs
Solution Approach 2:
The system implements dynamic channel switching where APs can autonomously change WDS channels in real-time based on current conditions, transforming the static manual configuration process into a flexible adaptive mechanism that responds immediately to changing environmental factors

AI summary
A method and system for autonomous channel coordination for a wireless distribution system (WDS) are disclosed. A wireless communication system includes a plurality of access points (APs) and the APs communicate each other via a WDS. A coordinated channel group (CCG) of a plurality of member APs is established. The member APs of the CCG camp on a WDS channel used for the WDS among the member APs of the CCG. One AP among the member APs of the CCG is designated as a master AP. The master AP coordinates with other member APs of the CCG for selecting and configuring the WDS channel for the CCG and addition and deletion of member APs. By allowing APs to define a CCG, changes of the WDS channel are performed autonomously while maintaining connectivity.
