Radio Apparatus Automatic Mode Switching for Network Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless LAN systems face challenges in maintaining stable communication by properly setting the base station mode or terminal mode in radio apparatuses that support both configurations, as these modes need to be selected arbitrarily and can affect network stability.
Innovation Solution
A radio apparatus is designed to select either a base station mode or a terminal mode based on communication requirements, using a control unit to switch between modes depending on the presence of beacon signals or battery levels, ensuring appropriate mode selection for stable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a radio apparatus supports both base station mode and terminal mode with arbitrary selection, then the adaptability and versatility of the apparatus is improved, but the network stability and reliability deteriorate due to improper mode selection
Solution Approach 1:
The radio apparatus monitors the wireless environment by detecting beacon signals from other base stations and receives mode selection instructions from connected terminal apparatuses. Based on this feedback information, the control unit automatically selects the appropriate mode (base station or terminal mode) to ensure network stability while maintaining versatility. This feedback mechanism resolves the contradiction by enabling adaptive mode selection that prioritizes reliability without sacrificing adaptability.
2Ease of operation
If the radio apparatus automatically switches between base station mode and terminal mode, then the ease of operation is improved, but the device complexity increases due to additional control mechanisms
Solution Approach 1:
The radio apparatus performs self-diagnosis and automatic mode selection based on detected wireless environment information and received instructions. The control unit autonomously determines whether to operate in base station mode or terminal mode without requiring manual user configuration, thereby improving ease of operation. The complexity is managed by implementing the control logic within the existing control unit framework, using simple decision rules based on beacon signal detection and instruction reception.
Data Source
AI summary
A data processing unit selects either one of a base station mode and a terminal mode so as to perform communications using packet signals. The base station mode is a mode in which a packet signal, containing data indicating that an initial source and a final destination are not its own radio apparatus, is to be communicated; the terminal mode is a mode in which a packet signal, containing data indicating that the initial source or the final destination is its own radio apparatus, is to be communicated. A control unit starts the radio apparatus by setting the data processing unit in the terminal mode. When a packet signal, which has been transmitted from another radio apparatus and which contains broadcast information, has not been received before a certain period of time elapses after the start, the control unit switches the mode of the data processing unit to the base station mode.
