Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi and LTE-U networks face congestion and unreliable connections due to inefficient management of unlicensed spectrum, lack of coordination between devices, and issues with radar detection in DFS channels, leading to underutilization of bandwidth and interference.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single access point performs DFS master services on one channel, then radar detection is possible, but spectrum utilization is underutilized and bandwidth is limited
Solution Approach 1:
The patent segments the DFS master functionality by separating radar detection operations from access point operations. Multiple access points can simultaneously perform radar detection on different channels without interfering with each other's network services, thereby multiplying the total spectrum utilization while maintaining reliable radar detection across all DFS channels.
Solution Approach 2:
The patent enables access points to serve multiple functions simultaneously: providing network access to clients on non-DFS channels while also performing radar detection on DFS channels. This multi-functionality allows the same hardware resources to contribute to both network service delivery and spectrum management, increasing overall productivity without sacrificing reliability.
2Reliability
If access points perform independent DFS monitoring, then each can detect local radar, but coordination between networks is lacking causing interference
Solution Approach 1:
The patent introduces a coordinating entity that acts as an intermediary between multiple access points performing DFS monitoring. This coordinator aggregates radar detection data from multiple APs, resolves conflicts, and distributes coordinated channel assignments, thereby maintaining accurate radar detection while adding structured coordination to reduce inter-network interference.
Solution Approach 2:
The patent merges the independent DFS monitoring functions of multiple access points into a coordinated system where detection capabilities are combined. By pooling radar detection efforts across multiple APs and centralizing decision-making, the system achieves both reliable detection (through multiple sensors) and reduced complexity (through centralized coordination).
3Object-affected harmful factors
If DFS channels are avoided due to radar detection requirements, then interference with radar is prevented, but available bandwidth decreases
Solution Approach 1:
The patent implements dynamic channel selection where access points can flexibly switch between DFS and non-DFS channels based on real-time radar detection results. When a DFS channel is clear of radar, it is dynamically activated for data transmission; when radar is detected, the system dynamically transitions to alternative channels. This dynamic approach maximizes bandwidth utilization while preventing harmful interference.
Solution Approach 2:
The patent changes the operational parameters of DFS channels based on detected conditions. Instead of permanently avoiding DFS channels, the system adjusts channel availability parameters in real-time: enabling DFS channels when safe, disabling them when radar is present, and transitioning clients to alternative channels. This parameter-based control allows full bandwidth availability when conditions permit while ensuring interference prevention when necessary.
