Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in wireless LANs is to balance the number of access points to avoid coverage holes while minimizing radio wave interference, as too many access points can cause communication obstacles.
Innovation Solution
An access point control device that identifies and manages proximal wireless LAN access points, instructing some to stand-by and others to remain active based on received radio wave strength thresholds, ensuring optimal communication coverage and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the number of wireless LAN access points is increased to eliminate coverage holes, then communication coverage is improved, but radio wave interference increases
Solution Approach 1:
The patent implements dynamic control of access point states, allowing access points to transition between active and standby states based on real-time communication needs. This dynamic adjustment enables the system to maintain adequate coverage while reducing interference by deactivating unnecessary access points.
Solution Approach 2:
The control device receives communication request information from terminals and uses this feedback to determine which access points should be active. This feedback mechanism ensures that access points are activated only when needed, balancing coverage requirements with interference reduction.
2Object-generated harmful factors
If the number of wireless LAN access points is decreased to reduce radio wave interference, then interference is reduced, but coverage holes increase
Solution Approach 1:
The system dynamically adjusts the number of active access points based on actual communication demand. When interference levels are high or communication load is low, access points are placed in standby state, reducing interference while maintaining the capability to provide coverage when needed.
Solution Approach 2:
The control device automatically manages access point states based on received communication requests, without requiring manual intervention. This self-service approach optimizes the balance between coverage and interference reduction based on real-time network conditions.
3Reliability
If multiple proximal access points communicate with the same terminal, then communication reliability is improved, but radio wave interference increases
Solution Approach 1:
The control device uses communication request information as feedback to determine the optimal number of active access points. This feedback control ensures that multiple access points are activated only when communication reliability is needed, while minimizing interference when single-point communication suffices.
Solution Approach 2:
The system changes the operational state parameter of access points between active and standby modes. This parameter change allows the system to adjust the degree of redundancy in communication paths, balancing reliability requirements against interference reduction goals.

AI summary
An access point control device controls a plurality of proximal wireless LAN access points arranged in proximity to each other and communicating with a communication terminal in a wireless LAN having an access point group of the proximal wireless LAN access points. The access point control device includes an identification information recording section and a terminal communication instructing section. The identification information recording section records identification information of the proximal wireless LAN access points. The terminal communication instructing section, based on records in the identification information recording section, instructs one or more of the proximal wireless LAN access points to stop communicating with the communication terminal and instructs the proximal wireless LAN access points other than the proximal wireless LAN access points instructed to stop communicating with the communication terminal to communicate with the communication terminal.
