Multipath Cellular Link Aggregation for Hotspot Bandwidth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hotspots using cellular wireless standards for internet connectivity face limitations in data rates and consistency, particularly when handling high-bandwidth applications like real-time video or audio streams, and are inefficient in utilizing multiple links due to variable link capabilities and network congestion.
Innovation Solution
An alternative networking structure utilizing multiple wireless links between a local area network and the internet, where client devices act as bridges by establishing connections to a cloud server, which acts as a gateway to the internet, enabling efficient data forwarding and prioritization through a tunneling mechanism, and optimizing packet scheduling and routing to compensate for signal variations and network performance fluctuations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cellular wireless link is used for internet connectivity, then device complexity is reduced, but data rate and connection reliability deteriorate
Solution Approach 1:
The patent combines multiple cellular wireless links (e.g., 3G, 4G, 5G) into a unified network infrastructure. Multiple client devices establish separate wireless connections to the same cellular network, which then aggregates their bandwidth to provide high-speed internet access to all clients simultaneously, resolving the contradiction between simple single-link configuration and high data rate requirements
Solution Approach 2:
The cellular network infrastructure is designed to serve multiple functions simultaneously - it acts as both the internet gateway and the bandwidth aggregation point. The system universally supports various wireless standards (3G, 4G, 5G) and can dynamically select the optimal link based on availability and performance, providing both simplicity and high speed
2Speed
If multiple cellular wireless links are used to increase data rate, then speed is improved, but device complexity and link management difficulty increase
Solution Approach 1:
The system automatically selects and manages the optimal cellular link for each client device without manual intervention. The network infrastructure self-adjusts link allocation, bandwidth distribution, and connection routing based on real-time network conditions, signal strength, and availability, eliminating the need for complex manual link management while maintaining high data rates
Solution Approach 2:
The system dynamically changes operational parameters such as bandwidth allocation, link selection, and connection priorities based on real-time network conditions. When cellular links become available or their performance varies, the system automatically adjusts these parameters to optimize data rates while managing complexity through automated parameter optimization
3Ease of operation
If conventional hotspot methods are used, then ease of operation is maintained, but productivity and bandwidth utilization deteriorate
Solution Approach 1:
The patent merges multiple cellular links into a single unified internet connection for all clients. Instead of each client managing separate connections, the system combines available cellular bandwidth into one aggregated pipeline, maintaining ease of operation while dramatically improving productivity and bandwidth utilization efficiency
Solution Approach 2:
The system continuously monitors network conditions, link availability, and bandwidth usage, then adjusts resource allocation and link selection based on this feedback. This automated feedback mechanism ensures optimal bandwidth utilization without requiring users to manually configure or manage complex network settings, maintaining ease of operation while maximizing productivity

AI summary
An agent manages multipath communications between a first network and a second network. The first network and a second network are wirelessly coupled by links through a plurality of wireless cellular devices. A link status monitor maintains a list of wireless cellular devices with bridging capability available for multipath communications between the first and second networks. A packet scheduler identifies segments of received packets originating from the second network and assigns one or more wireless cellular devices selected from the list to the identified segments. A packet transmitter encapsulates the segments of packets so identified and addresses the encapsulated segments to the assigned wireless cellular devices.
