Concurrent Multiple Band Wireless Routing for QoS Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in routing application streams across multiple Basic Service Sets (BSSs) in different wireless communication bands, leading to sub-optimal Quality of Service (QoS) and performance due to static routing configurations that do not account for dynamic network conditions.
Innovation Solution
The implementation of a Concurrent Multiple Band (CMB) routing scheme that dynamically routes application streams across multiple radios operating in different wireless communication bands (such as 2.4 GHz, 5 GHz, and 6-7 GHz) based on Quality of Service (QoS) requirements and real-time network condition information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static routing configurations are used to route application streams across multiple BSSs, then device complexity is reduced, but QoS and performance deteriorate due to inability to adapt to dynamic network conditions
Solution Approach 1:
The patent implements dynamic routing by continuously monitoring network conditions (signal strength, interference levels, channel availability) and automatically adjusting routing decisions in real-time. The system transitions from static pre-configured routing to dynamic adaptive routing that responds to changing wireless environment conditions, thereby improving QoS without requiring complex manual reconfiguration.
Solution Approach 2:
The system incorporates feedback mechanisms where routing decisions are based on real-time network condition information received from multiple BSSs. The router monitors performance metrics and uses this feedback to optimize routing paths, creating a closed-loop control system that continuously improves QoS based on actual network behavior rather than relying on fixed static configurations.
2Productivity
If concurrent communication with multiple BSSs in different bands is enabled, then productivity is improved through better traffic distribution, but device complexity increases due to multiple radios and routing management
Solution Approach 1:
The patent implements a universal routing mechanism that handles multiple wireless bands (2.4 GHz, 5 GHz, 6-7 GHz) through a single integrated CMB routing scheme. Rather than requiring separate management systems for each band, the invention creates a unified approach that treats all BSSs consistently, simplifying multi-radio management while enabling concurrent communication across different frequency bands for improved system efficiency.
Solution Approach 2:
The system segments traffic into different application streams based on QoS requirements and routes them through different radios and BSSs accordingly. By dividing the routing decision-making process into manageable segments (per-application-stream routing), the system handles multiple bands and radios in an organized manner, reducing the complexity of managing concurrent communications across multiple frequency bands.
3Reliability
If dynamic routing based on real-time network conditions is implemented, then QoS improves for latency-sensitive applications, but loss of time increases due to continuous monitoring and routing updates
Solution Approach 1:
The system implements periodic monitoring of network conditions rather than continuous real-time processing. Routing updates are performed at optimized intervals based on network stability and change detection, allowing the system to maintain QoS for latency-sensitive applications while reducing the time overhead associated with constant routing recalculations. The periodic action enables timely responses to network changes without excessive processing frequency.
