Solution Overview

Problem

Current multi-band wireless devices operate independently across different frequency bands, lacking seamless integration and efficient communication mechanisms, which hinders real-time data link integration and user experience.

Innovation Solution

A wireless communication system with a single Station-Management-Entity (SME) coupled to multiple radios, enabling simultaneous and integrated operation across various frequency bands, including 2.4GHz, 5GHz, and 60GHz, through a multi-band operation mechanism that manages association, traffic streams, and security key management transparently across MAC/PHY stacks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If devices operate independently across different frequency bands, then each band can be managed separately with simpler control, but real-time data link integration and seamless communication across bands are hindered

Engineering Contradiction:
Improveindependent band managementVSAvoidreal-time data link integration
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent merges multiple independent frequency band operations under a single Station Management Entity (SME) that coordinates across all bands. The SME consolidates association management, traffic stream control, and security key management into a unified structure, enabling seamless integration while maintaining the operational independence of individual bands through the multi-band operation mechanism.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If a single Station-Management-Entity manages multiple frequency bands simultaneously, then real-time integration and seamless communication are achieved, but system complexity increases

Engineering Contradiction:
Improvereal-time data link integrationVSAvoidsingle SME managing multiple bands
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the management functions into distinct modules within the single SME: association management module, traffic stream management module, and security key management module. Each module handles specific aspects of multi-band operation independently, reducing the complexity burden on the overall SME structure while maintaining integrated control across all frequency bands.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple radios operate simultaneously across different frequency bands, then communication versatility is improved, but coordination and management become more difficult

Engineering Contradiction:
Improvemulti-band communication capabilityVSAvoidcoordination across multiple radios
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal Station Management Entity that performs multiple functions across all frequency bands: association management, traffic stream control, and security key management. This single multi-functional SME replaces what would otherwise require separate management entities for each radio and frequency band, simplifying coordination while maintaining versatility across 2.4GHz, 5GHz, and 60GHz bands.

Inventive Principle:
Principle #6Universality (Multi-functionality)
