Vehicular Multi-Link Bonding for Broadband Coverage and Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems for vehicles, especially in transportation and autonomous vehicles, face limitations in geographical coverage and bandwidth, leading to insufficient broadband connections, which are exacerbated by factors like RF interference, congestion, and weather conditions, making it difficult to support bandwidth-intensive applications such as HD video streaming and real-time data processing.
Innovation Solution
A vehicular communication system that dynamically aggregates multiple wireless communication links, including cellular, Wi-Fi, satellite, and V2X networks, to create a bonded broadband connection, optimizing data transfer through a Bonding/Multi-Link Agent that allocates bandwidth based on performance and application priorities, using virtual SIMs for network switching and ensuring reliable high-speed communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single cellular communication link is used for vehicular data transmission, then the device complexity is low, but the bandwidth and reliability are insufficient
Solution Approach 1:
The patent combines multiple cellular communication links (at least two different links) into a unified communication system for vehicular data transmission. The bonding unit aggregates these separate links to provide increased bandwidth and improved reliability while maintaining manageable system complexity through centralized control.
2Reliability
If multiple wireless communication links are aggregated, then the broadband connection quality improves, but the device complexity increases
Solution Approach 1:
The bonding unit acts as an intermediary component that manages multiple cellular communication links. It handles the complexity of link aggregation, packet routing, and data stream management internally, while presenting a simplified interface to the vehicular transceiver and remote server, thus improving reliability without proportionally increasing external system complexity.
3Productivity
If data packets are transmitted over multiple communication links, then the data transfer speed increases, but the synchronization and packet reassembly complexity increases
Solution Approach 1:
The bonding unit segments the data stream into multiple batches, with different batches transmitted over different cellular communication links. Each link carries a portion of the overall data stream, allowing parallel transmission that increases data transfer speed. The bonding unit manages the segmentation and reassembly processes to handle the complexity internally.

AI summary
Devices, system, and method of vehicular multiple-link wireless communication. A vehicular communication bonding unit creates a bonded wireless communication connection that transports data-packets of a source data-stream from a remote server to a vehicular transceiver, by transporting the data-packets over at least two wireless communication links. The vehicular communication bonding unit utilizes a vehicular cellular transceiver to receive a first batch of the data-packets over a first cellular communication link that connects between the vehicular cellular transceiver and the remote server. The vehicular communication bonding unit further utilizes least one end-user device, of an occupant of a vehicle, to receive a second batch of the data-packets of the particular data-stream, over a second cellular communication link that connects between the end-user device and the remote server.
