Multi-band Wireless Session Transfer Between Frequency Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication links over Extremely High Frequency (EHF) or mmwave frequency bands, such as 60 GHz, are less robust due to oxygen absorption, leading to instability compared to lower frequency bands like 2.4/5 GHz, which affects throughput and reliability.
Innovation Solution
A system and method for transferring wireless communication sessions between different frequency bands, including the 60 GHz and 2.4/5 GHz bands, using a multi-band wireless communication unit that can handle session transfers through transparent or non-transparent modes, enabling seamless communication by informing devices of supported modes and MAC addresses for uninterrupted operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If communication is performed over mmwave frequency band (30-300 GHz), then throughput is improved, but reliability deteriorates due to oxygen absorption
Solution Approach 1:
The system dynamically switches between mmwave and lower frequency bands based on communication conditions. The multi-band wireless communication unit monitors link quality and automatically transitions sessions between frequency bands to maintain optimal performance, making the system adaptable to changing environmental conditions rather than static
Solution Approach 2:
The invention changes the operating frequency parameter by transferring communication sessions between different frequency bands (mmwave and lower bands). This parameter change allows the system to exploit the high throughput of mmwave when conditions permit, while falling back to more robust lower bands when oxygen absorption degrades link quality
2Reliability
If session transfer between frequency bands is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The multi-band wireless communication unit is designed with multi-functionality, capable of operating across multiple frequency bands and handling session transfers transparently. This universal design consolidates what could be multiple separate systems into a single integrated unit, managing complexity internally while presenting a unified interface to users and applications

Implementation Method 1
communication link over the mmwave frequency band may be less robust than a communication link operating over a lower frequency band, e.g., a 2.4 GHz or 5 GHz ('2.4/5 GHZ') frequency band, for example, due to oxygen absorption
