Dual Carrier Data Transmission for IoT Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods in wireless communication, particularly for IoT devices, face challenges in achieving ultra-reliable and low-latency connections due to higher potential delays and inefficiencies in reliability mechanisms like HARQ and backup connections, which can lead to synchronization issues and reduced throughput.
Innovation Solution
A method utilizing dual wireless carriers for redundant data transmission, where both carriers are used in parallel to send and receive data packets, with success indication messages sent over both carriers to ensure reliable data transfer without increasing latency, allowing for seamless switching between carriers if one fails, thus maintaining high throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HARQ mechanism is used for reliable data transmission, then transmission reliability is improved, but transmission delay increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple wireless carriers and establishing backup transmission paths before data transmission is needed. When a carrier fails, the system can immediately switch to a pre-established backup carrier without waiting for retry mechanisms, thus achieving high reliability without the delay penalty of HARQ retransmissions.
2Reliability
If backup connection via another carrier is used, then transmission reliability is improved, but synchronization issues and management overhead increase
Solution Approach 1:
The patent merges the management of multiple wireless carriers into a unified framework where the system monitors and manages all carriers through a single control mechanism. This consolidation reduces the management overhead that would otherwise arise from separately managing multiple backup connections, while still providing reliable failover capability.
3Productivity
If fully parallel transmission over multiple carriers is used, then transmission speed is improved, but synchronization issues arise
Solution Approach 1:
The patent applies preliminary action by pre-synchronizing multiple wireless carriers before data transmission begins. The system establishes timing and phase relationships among carriers in advance, so that when parallel transmission occurs, synchronization is already in place. This eliminates real-time synchronization complexity while maintaining high transmission speed.
