Multi-Link Mobile Communications System for High-Speed Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Radio Frequency (RF) cellular telephony data rates are insufficient for high-demand mobile data transfers, such as movies and music, and become even slower when base stations are overloaded, making large data transfers impractical.
Innovation Solution
A communication system that uses a processor to determine the location of a mobile device and coordinates data transfers through multiple directional communication links, such as RF or optical links, to efficiently hand off data as the device moves, optimizing data rates and quality by switching between links based on predicted locations and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional RF cellular telephony is used for data transfer, then the system is simple and widely deployed, but data rates are too slow for high-demand mobile data transfers
Solution Approach 1:
The patent combines multiple communication links (RF cellular, wireless LAN, satellite, optical) into a unified communication system that dynamically selects and switches between available links based on data rate requirements and environmental conditions, achieving high-speed data transfer while managing system complexity through integration
Solution Approach 2:
The communication system is designed to handle multiple types of data transfer requirements using different communication links simultaneously - RF for mobile voice and data, wireless LAN for high-speed local data transfer, satellite for remote areas, and optical for fixed high-bandwidth connections, making the system universally applicable to diverse communication needs
2Productivity
If base stations are overloaded with users, then more users can be served, but downlink data rates decrease significantly
Solution Approach 1:
The patent segments the communication system into multiple independent communication links (cellular RF, wireless LAN, satellite, optical) that can operate simultaneously, allowing users to be distributed across different links based on their data rate requirements and available capacity, preventing any single link from becoming a bottleneck
Solution Approach 2:
The system dynamically assigns users to different communication links based on real-time conditions, allowing high-data-rate users to access wireless LAN or optical connections while mobile users utilize RF cellular service, enabling the system to adapt to varying user demands and maintain optimal performance across all users
3Adaptability or versatility
If a single communication link is used for data transfer, then the system is simple to manage, but the link cannot adapt to mobile device movement and changing conditions
Solution Approach 1:
The patent implements feedback mechanisms where the communication system continuously monitors the location, movement speed, and signal conditions of mobile devices, and dynamically adjusts the selected communication link and data transfer parameters in real-time based on this feedback to maintain optimal connectivity
Solution Approach 2:
The system performs preliminary actions by predicting future device locations and pre-establishing communication paths before the device actually moves, allowing smooth transitions between communication links and maintaining continuous high-speed data transfer without interruption

AI summary
Systems and methods presented herein provide for improved access to data. In one embodiment, a communication system includes an RF communication link that is operable to receive first communications from a mobile device (e.g., a cell phone, tablet computer, laptop computer, or other “user equipment”). The communication system also includes a processor operable to determine a location of the mobile device based on the first communications and a plurality of directional communication links. Each directional communication link is operable to transfer data to the mobile device based on the location of the mobile device as determined by the processor. The processor is also operable to coordinate the transfer of data from each of the directional communication links to the mobile device.
