Dynamic Wi-Fi Router Handoff for High-Density Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing wireless coverage in high-density wireless environments is challenging due to signal interference from densely located neighboring access points, leading to poor or inconsistent wireless signals and quality of service (QoS) for customers.
Innovation Solution
A client device associated with a router in a high-density wireless environment detects low signal strength and compiles an evidentiary report. This report is sent to a network connection manager, which configures a neighboring router with the customer-specific SSID of the client device, allowing it to connect with better signal strength and QoS, while ensuring that the neighboring router has sufficient available bandwidth to support the client device without compromising QoS for other users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customers use their own assigned router in a high-density wireless environment, then they maintain network security and LAN privacy, but they experience poor signal strength and inconsistent QoS due to signal interference from neighboring access points
Solution Approach 1:
The patent introduces a network connection manager as an intermediary that coordinates between multiple access points and client devices. This manager dynamically assigns client devices to different access points based on current signal conditions, load balancing across the network, and QoS requirements, thereby resolving the signal interference problem without compromising security since the management layer handles the coordination
Solution Approach 2:
The system implements dynamic access point assignment where client devices can switch between their assigned access point and neighboring access points based on real-time signal strength and network conditions. This dynamic reassignment allows clients to maintain connection to the most reliable access point while the network manager ensures proper authentication and security policies are maintained
2Reliability
If customers connect to neighboring routers with better signal, then they improve wireless connection quality, but they compromise LAN privacy and security as LAN traffic traverses to the edge of the LAN boundary
Solution Approach 1:
The network connection manager acts as an intermediary that enables secure cross-access-point communication. When a client device connects to a neighboring access point, the manager establishes proper tunneling and routing rules that ensure LAN traffic remains isolated to the client's home network boundary, preventing unauthorized access to other networks while still allowing the client to benefit from better signal strength
Solution Approach 2:
The patent implements local quality by maintaining distinct virtual network boundaries for each client's LAN traffic even when physically connected to different access points. Each client's traffic is tagged and routed through virtual interfaces that preserve the illusion of being connected to their local router, ensuring LAN privacy is maintained at the logical layer regardless of physical connection location
3Adaptability or versatility
If multiple access points operate independently in high-density environments, then each maintains its own channels, but signal interference increases due to channel overlap and adjacent channel use
Solution Approach 1:
The patent merges the channel management functions of multiple independent access points under a coordinated framework managed by the network connection manager. The manager monitors channel usage across all access points and dynamically assigns non-overlapping channels, effectively combining their operations to eliminate interference while preserving each access point's operational independence at the local level
Solution Approach 2:
The system dynamically changes operational parameters (channel assignments, transmit power levels, operating modes) of access points based on real-time network conditions and interference measurements. This parameter optimization is performed centrally by the network manager while allowing each access point to maintain its basic operational autonomy, resolving the contradiction between independence and interference avoidance
Data Source
AI summary
Systems and methods for managing coverage in a high-density wireless environment are disclosed. A client device detects low signal strength from its assigned router. The signal strength of a neighboring router is determined to be higher than that of the assigned router. Based on the determination, the neighboring router is configured with a customer-specific SSID of the client device. The client device uses its customer-specific SSID to connect with the neighboring router. Upon determining that the neighboring router has available bandwidth to support a bandwidth request of the client device, the bandwidth is provisioned to the client device from the neighboring router. Routers with low signal strengths may be selectively disabled and collect signal strength data of neighboring routers. Active routers maybe configured with the respective customer-specific SSIDs of the disabled routers. A switch is installed at the front-end of all routers maintains LAN traffic within the LAN boundaries.
