Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for setting a peer-to-peer (P2P) operating channel in Wi-Fi direct connections between display apparatuses and portable devices are inefficient, leading to suboptimal wireless network performance due to interference and bandwidth utilization issues, particularly in scenarios where concurrent connections occur across different frequency bands.
Innovation Solution
A display apparatus equipped with a transceiver and controller that determines a P2P operating channel based on stored access point connection information, optimizing the channel selection to minimize interference by prioritizing the 5 GHz frequency band and reducing multi-channel concurrency, thereby enhancing wireless network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If P2P operating channel is determined without considering AP connection information, then device complexity is reduced, but wireless network performance deteriorates due to interference and bandwidth utilization issues
Solution Approach 1:
The system performs preliminary actions by storing AP connection information (including operating channel frequency band and channel number) before establishing P2P connections. When a P2P connection is needed, the controller retrieves this pre-stored information to determine the P2P operating channel, avoiding real-time complexity while ensuring optimal performance.
Solution Approach 2:
The system uses feedback from stored AP connection information to dynamically determine P2P operating channels. The controller references previously collected AP connection data (frequency band, channel number) to make informed channel selection decisions, creating a feedback loop that optimizes wireless performance without adding real-time computational complexity.
2Productivity
If P2P connection is established without optimizing operating channel, then ease of operation is improved, but throughput decreases and packet loss increases due to interference
Solution Approach 1:
The system performs preliminary actions by storing AP connection information (including operating channel frequency band and channel number) before establishing P2P connections. When a P2P connection is needed, the controller retrieves this pre-stored information to determine the P2P operating channel, avoiding real-time complexity while ensuring optimal performance.
Solution Approach 2:
The system changes parameters by selecting P2P operating channels based on stored AP connection information, prioritizing the 5 GHz frequency band over 2.4 GHz. This parameter optimization reduces interference and improves throughput while maintaining ease of operation through automated channel selection.
3Reliability
If concurrent connections across different frequency bands are allowed, then adaptability is improved, but interference increases and wireless network performance deteriorates
Solution Approach 1:
The system applies local quality by making the P2P connection quality depend on the specific frequency band and channel selection. By prioritizing 5 GHz bands and selecting channels based on stored AP connection information, the system ensures high-quality P2P connections while managing concurrent connections more effectively, reducing interference without completely limiting frequency band flexibility.
