Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies face challenges in maintaining consistent data reception quality, particularly for mobile transmitters using unstable radio frequency (RF) methods, when transmitting large volumes of time-critical data such as audio and video, due to issues like dynamic fading, dead zones, and RF interference.
Innovation Solution
A system and method utilizing multiple paths for data transmission, where source data is encoded and divided into multiple streams, with a buffer management and transport controller that adjusts data transmission based on feedback status information from RF interface modules, allowing for dynamic rerouting and redundancy to ensure reliable delivery across wireless networks.

Engineering Contradiction Analysis
1Reliability
If multiple data channels are used to augment data throughput, then data transmission reliability is improved, but system complexity increases due to need for Forward Error Correction and data rate adjustments
Solution Approach 1:
The source data stream is divided into multiple independent data channels, each transmitted separately through the wireless network. This segmentation allows the system to achieve diversity gain and improve reliability without requiring complex end-to-end error correction mechanisms, as each segment can be independently received and reassembled at the destination.
Solution Approach 2:
Data is pre-buffered at the transmitter before transmission begins. This preliminary buffering allows the system to accumulate sufficient data segments across multiple channels before reconstruction is needed at the receiver, eliminating the need for complex real-time error correction and rate adjustment mechanisms during transmission.
2Adaptability or versatility
If data is transmitted over unstable RF methods from mobile transmitters, then wireless mobility is achieved, but data reception quality deteriorates due to dynamic fading, dead zones, and RF interference
Solution Approach 1:
By dividing the data stream into multiple independent channels transmitted over different RF paths, the system ensures that if one path experiences fading or interference, other paths can still deliver data segments. This segmentation provides spatial and path diversity that mitigates the effects of unstable RF conditions while maintaining mobile transmitter capability.
3Productivity
If the up-channel transmission capacity is limited compared to down-channel, then wireless network balance is maintained, but large volume time critical data transmission from mobile devices becomes difficult
Solution Approach 1:
The data transmission is divided into multiple parallel channels, effectively multiplying the up-channel capacity. By transmitting multiple segments simultaneously over different channels rather than sequentially over a single limited channel, the system achieves higher aggregate throughput while maintaining the physical constraints of the up-channel hardware.
Solution Approach 2:
Multiple data channels are combined at the receiver to reconstruct the complete data stream. This merging of parallel transmission paths creates an effective capacity greater than any single channel, enabling large volume time-critical data transmission despite individual up-channel limitations.
4Productivity
If multiple paths are used for data transmission, then data throughput is enhanced, but transmission path management complexity increases
Solution Approach 1:
The system employs automatic path selection and data routing mechanisms that operate without manual intervention. The transmitter and receiver automatically manage which paths are active and how data segments are routed and reassembled, reducing the operational complexity of managing multiple transmission paths while maintaining enhanced throughput.

AI summary
A method and system for streaming large quantities of data over multiple distinct wireless channels from a mobile device to a central receiver by converting single source data into multiple data streams, placing them in transport buffers and storing them for forwarding via a plurality of radio frequency modules. Links are maintained to provide feedback on network connections to allow for the selection of networks and the transfer of data from one network to another and to adjust the amount of data being transmitted.
