Network Connection Management via Dynamic Band Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-band wireless networks, particularly those operating at 5 GHz, face reliability issues due to channel overlap with radar systems, leading to decreased performance when multiple devices switch channels simultaneously, resulting in crowded and less reliable connections.
Innovation Solution
A method and system for managing network connections by switching between 2.4 GHz and 5 GHz bands based on network activity monitoring, generating profiles for each band, and selecting the more reliable connection, allowing devices to switch back and forth between these bands while idle to optimize performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dual-band wireless access points are introduced to address network crowding, then network capacity is improved, but reliability deteriorates due to radar interference and channel switching issues
Solution Approach 1:
The system dynamically monitors network conditions including signal strength, interference levels, and channel availability, then adapts connection parameters in real-time. The access point and client devices continuously adjust their operating parameters based on monitored conditions, transforming the static dual-band system into a dynamic one that can respond to changing environmental factors and avoid radar interference zones.
Solution Approach 2:
The patent implements a feedback mechanism where network activity is monitored and used to generate profiles for different frequency bands. The system compares these profiles and uses the comparison results to select optimal connections, creating a closed-loop control system that continuously improves reliability based on observed performance data.
2Adaptability or versatility
If dynamic frequency selection is implemented to avoid radar interference, then frequency compatibility is improved, but network reliability deteriorates when multiple devices switch channels simultaneously
Solution Approach 1:
The system performs preliminary monitoring of network conditions and generates connection profiles before actual data transmission begins. By pre-assessing channel quality, signal strength, and interference levels, the system can select optimal frequencies in advance, avoiding the need for simultaneous mid-transmission channel switches that cause reliability issues.
Solution Approach 2:
The patent segments the network monitoring and selection process into distinct phases: monitoring network activity, generating profiles for different bands, comparing profiles, and selecting connections. This segmentation allows devices to make independent, coordinated decisions about channel switching rather than forcing simultaneous switches across all devices.

AI summary
Methods, systems, and media for controlling network connections are provided. In some implementations, a method for controlling network connections is provided, the method comprising: determining, by a user device connection to an access point by a first network connection, that a second network connection is available; determining that the user device is in an idle state; while the user device is in the idle state, switching from the first network connection to the second network connection; monitoring network activity using the second network connection; switching back to the first network connection; generating a profile for the second network connection based at least in part on the monitored network activity; comparing the profile for the second network connection to a profile for the first network connection; selecting the second network connection based on the comparison; and in response to selecting the second network connection, switching to the second network connection.
