Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in providing adequate bandwidth for uplink transmissions, especially for devices near the cell edge, and experience interference and limited throughput due to multiple modem systems, which are inadequate for handling large data streams required by emergency response vehicles and devices.
Innovation Solution
A multi-link device with a set of antennas and processors establishes concurrently active WAN connections based on LAN connections, mapping data to appropriate base stations for transmission, reducing the need for multiple modems and enhancing uplink throughput and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple modem systems are used to handle large data streams, then bandwidth capacity is improved, but device complexity and interference increase
Solution Approach 1:
The patent combines multiple modem functions into a single multi-link device that can establish concurrent WAN connections. Instead of using separate modem systems, the invention integrates multiple connection management capabilities into one device, reducing overall system complexity while maintaining the ability to handle large data streams through multiple simultaneous connections to different base stations
Solution Approach 2:
The multi-link device serves multiple functions: it acts as a modem, router, and connection manager simultaneously. This universal device can establish and manage multiple WAN connections to different base stations, map LAN connections to appropriate WAN connections, and handle data routing, thereby replacing what would traditionally require multiple specialized devices
2Productivity
If multiple modem systems are deployed to increase throughput, then bandwidth is improved, but interference between modems increases
Solution Approach 1:
The patent segments data traffic into different VLANs and maps them to specific WAN connections based on bandwidth requirements and quality of service parameters. By dividing and routing different data streams through dedicated connections to different base stations, the system achieves high throughput while minimizing interference between different data flows
Solution Approach 2:
The multi-link device acts as an intermediary that intelligently routes data packets through appropriate WAN connections. It monitors connection quality, bandwidth availability, and QoS requirements to select the optimal path for each data stream, thereby managing throughput while reducing interference through intelligent traffic management
3Reliability
If WAN connections are established based on quality of service requests, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary quality of service assessments when establishing WAN connections. The multi-link device evaluates base station signal quality, available bandwidth, and connection reliability before committing to a connection, and maps LAN connections to WAN connections based on these pre-assessed QoS parameters, ensuring reliable communication from the outset

AI summary
The technology disclosed herein relates to a multi-link device and methods, media, and systems associated with the multi-link device. The multi-link device can establish multiple wide area network (WAN) connections with multiple base stations. The multi-link device has multiple sets of antennas, and each WAN connection is associated with at least one of the multiple sets of antennas. The multi-link device also has a local area network (LAN) interface that is capable of establishing a plurality of LAN connections. The multi-link device can determine which of the WAN connections has a highest uplink bandwidth or a lowest uplink bandwidth. In some embodiments, the multi-link device ranks each of the WAN connections based on uplink bandwidth. Further, the multi-link device can transmit various sets of data (e.g., video data, image data, audio data, location data) to the multiple base stations via the WAN connections that are concurrently active.
