Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks, including 4G LTE, struggle to consistently and reliably transmit high definition video due to capacity limitations and fluctuations, especially in crowded areas where multiple devices compete for limited resources, leading to issues with data throughput, error resilience, and latency.
Innovation Solution
A system that dynamically encodes video data into multiple buffers and processes feedback to adjust data transmission across multiple network connections, utilizing a multipath wireless router to split data streams across available Wi-Fi and cellular networks, ensuring reliable and high-quality video transmission by bonding network connections and adapting to real-time performance data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted over a single wireless network connection, then the system complexity is low, but the data throughput and reliability are insufficient for high definition video transmission
Solution Approach 1:
The patent divides the video data stream into multiple segments and transmits them simultaneously over multiple wireless network connections (WiFi, cellular, satellite). Each connection carries a portion of the data, and the receiver reassembles the segments. This segmentation increases reliability by ensuring that if one connection fails, other connections can still deliver the data, while managing complexity through automated routing protocols.
Solution Approach 2:
The patent combines multiple wireless network connections (WiFi, cellular, satellite) into a unified transmission system. The router aggregates these diverse connections and manages data flow across them, merging their individual capacities to achieve higher overall throughput and reliability. This merging allows the system to leverage the strengths of each connection type while presenting a single coherent interface to the user.
2Productivity
If multiple network connections are used for data transmission, then the data throughput increases, but the device complexity and routing management become more difficult
Solution Approach 1:
The patent implements self-service mechanisms where the system automatically monitors network performance, dynamically adjusts routing decisions, and manages data flow across multiple connections without requiring manual intervention. The router autonomously handles connection establishment, data segmentation, and path selection based on real-time network conditions, reducing the operational complexity despite using multiple connections.
Solution Approach 2:
The patent employs dynamic routing that adapts to changing network conditions in real-time. The system continuously monitors the performance of each connection and dynamically adjusts the distribution of data segments across connections. This dynamic behavior allows the system to optimize throughput by shifting traffic to the best-performing connections while automatically managing the complexity of multi-path routing.
3Reliability
If data is buffered extensively to handle network fluctuations, then the transmission reliability improves, but the latency increases
Solution Approach 1:
The patent implements preliminary actions by pre-segmenting video data and proactively distributing segments across multiple network connections before transmission issues occur. The system establishes multiple active connections and begins routing data segments across them in advance, so that when network fluctuations occur, the data is already in transit through alternative paths, reducing the need for extensive buffering and minimizing latency.
