Radio Channel Bonding Across Frequency Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for wireless communication in a crowded radio frequency (RF) spectrum often results in non-licensed users facing difficulties in finding available radio channels with sufficient bandwidth, as individual bands are regulated differently and may not have enough bandwidth to handle communication tasks.
Innovation Solution
The implementation of radio channel bonding, where available channels from different RF bands are combined to satisfy bandwidth requirements, allowing for the transmission and reception of data streams across multiple channels using error correction coding and inverse/fast Fourier transform processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-broadcast users select between available channels in various bands, then communication flexibility is improved, but sufficient bandwidth cannot be guaranteed for communication tasks
Solution Approach 1:
The patent combines multiple radio channels from different frequency bands into a bonded channel aggregate. The communication manager bonds a first radio channel from a first frequency band with a second radio channel from a second frequency band, creating a unified communication path that aggregates bandwidth from multiple sources to satisfy communication task requirements.
2Adaptability or versatility
If individual radio frequency bands are managed with different bandwidth increments, then regulatory flexibility is improved, but total available bandwidth for non-broadcast users is reduced
Solution Approach 1:
The communication manager performs universal channel bonding operations across multiple frequency bands with different regulatory requirements. The system can bond channels from bands regulated in 1 MHz increments with channels from bands regulated in 6 MHz increments, creating a unified interface that abstracts away the underlying regulatory differences and presents a consistent bandwidth aggregation capability.
3Quantity of substance
If channels from different frequency bands are bonded together, then sufficient bandwidth is achieved, but system complexity increases
Solution Approach 1:
The communication manager acts as an intermediary layer between the physical radio channels and the communication tasks. It manages the channel bonding process, handling the complexity of combining channels from different frequency bands with different characteristics, while presenting a simplified interface to upper-layer protocols and applications.

AI summary
The concepts relate to radio channel utilization. One example can channel bond a first available channel from a first radio frequency band with a second available channel from a second radio frequency band. The example can transmit a portion of a forward error correction coded data stream over the first available channel and a different portion of the forward error correction coded data stream over the second available channel.
