Multi-Band Wireless Device Station Management Entity Integration
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
3Adaptability or versatility
If multiple radios operate simultaneously across different frequency bands, then communication versatility is improved, but coordination and management become more difficult
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.

AI summary
Devices, systems and methods of communication over multiple wireless communication frequency bands. For example, a multiple frequency band (multi-band) wireless communication device may include at least two radios to communicate over at least two different frequency bands; and a common station management entity (SME) operably coupled to the at least two radios, and configured to manage parallel and simultaneous operation of the at least two radios.
