Diversity Matrix for Wireless Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network systems face challenges in maintaining high reliability while avoiding packet retransmission to minimize communication latency, particularly in mission-critical systems where latency is a concern.
Innovation Solution
The network system employs a diversity matrix to establish redundant data exchange connections across multiple access points, frequency values, and time domains, allowing for dynamic configuration to ensure data transmission reliability by utilizing spatial, frequency, and time redundancy, and a diversity controller to adjust configurations based on detected data transmission characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet retransmission is used to increase reliability, then data transmission reliability is improved, but communication latency increases
Solution Approach 1:
The system performs preliminary actions by transmitting redundant data packets through multiple diverse connections (different access points, frequencies, and time slots) before the original packet is lost. This proactive redundancy ensures that if one connection fails, alternative paths are already available, eliminating the need for reactive retransmission and thus reducing latency while maintaining reliability
2Reliability
If redundant data transmission connections are established across multiple domains, then data transmission reliability is improved, but system complexity increases
Solution Approach 1:
The system segments the redundancy mechanism into three independent domains: spatial (multiple access points), frequency (multiple carrier frequencies), and time (multiple time slots). Each domain can be configured and managed separately through the diversity matrix, allowing selective application of redundancy where needed without requiring complete system-wide complexity. This modular segmentation enables reliable data transmission while controlling overall system complexity
Solution Approach 2:
The diversity matrix provides dynamic configuration capabilities, allowing the system to adaptively select and adjust the number and type of redundant connections based on current network conditions, data priority, and reliability requirements. This dynamic approach enables the system to optimize reliability while minimizing complexity by only establishing redundant connections when and where necessary, rather than maintaining fixed maximum redundancy across all transmissions

AI summary
A network system includes access points and wireless devices. Each wireless device can exchange data with at least one access point that includes a diversity matrix defining at least two data exchange connections between a first wireless device and at least one access point for exchanging data between the first wireless device and the at least one access point. The diversity matrix indicates a space domain with at least one access point, a frequency domain with at least one data transmission frequency value, and a time domain with at least one data transmission time. Each data exchange connection is defined by an access point, a data transmission frequency, and a data transmission time, selected from the diversity matrix. The at least two data exchange connections between the first wireless device and the at least one access point are configured to transmit the same information.
