Adaptive Channel Setting for Wireless LAN Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless mesh network systems, setting channels for wireless network terminals is difficult and time-consuming, especially when considering radio wave conditions, which limits the flexibility of terminal deployment and efficient communication.
Innovation Solution
A channel setting apparatus with two transmitter-receivers and a channel controller that searches for available communication channels and adjusts settings based on surrounding radio wave conditions to ensure different channels are used by each transmitter-receiver, allowing for automatic channel setting according to the installation environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channels are manually set considering radio wave conditions, then communication efficiency is improved, but deployment flexibility and relocation freedom deteriorate
Solution Approach 1:
The wireless network terminal automatically performs channel searching and selection without manual intervention. The terminal itself detects surrounding radio wave conditions and autonomously determines optimal channel assignments, eliminating the need for manual channel configuration while maintaining communication efficiency.
Solution Approach 2:
The terminal performs channel searching and environment detection in advance before actual communication begins. By pre-detecting radio wave conditions and selecting appropriate channels beforehand, the system ensures efficient communication is established automatically when the terminal is deployed or relocated.
2Quantity of substance
If multiple channels are assigned to wireless network terminals, then usable bandwidth is increased, but channel setting complexity and time consumption increase
Solution Approach 1:
The terminal automatically searches for available channels and assigns multiple channels to itself without external intervention. This self-service approach allows the terminal to independently manage its own channel configuration, increasing usable bandwidth while avoiding the complexity of manual multi-channel setting.
Solution Approach 2:
The terminal detects surrounding radio wave conditions and uses this feedback information to intelligently select and assign multiple channels. By continuously monitoring the environment and adjusting channel assignments based on detected conditions, the system optimizes bandwidth utilization while simplifying the setting process.
3Reliability
If channels are set based on installation environment, then communication reliability is improved, but setting time and operational difficulty increase
Solution Approach 1:
The terminal autonomously detects installation environment conditions and configures channels accordingly without requiring manual setting. This eliminates the time-consuming process of manual channel configuration while ensuring communication reliability is optimized for the specific installation environment.
Solution Approach 2:
The terminal performs environment detection and channel selection in advance before communication begins. By pre-configuring channels based on detected radio wave conditions, the system ensures reliable communication is established automatically, eliminating the need for time-consuming manual setting procedures.

AI summary
A wireless LAN includes two interfaces with a transmitter-receiver function and a channel controller. One of the two interfaces employs one communication channel to search for a communication channel being used by a destination communication unit. The channel controller determines a surrounding radio wave condition based on the communication channel obtained by the searching, and controls channel setting so that the respective communication channels of the two interfaces differ from each.
