Redundant Wireless System Channel Hopping Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems between infrastructure and leaf nodes lack efficient redundancy mechanisms for data transmission and timing synchronization, particularly in scenarios where channel changes are frequent, leading to potential losses and synchronization issues.
Innovation Solution
The implementation of redundant wireless systems with multiple infrastructure nodes and leaf nodes that utilize state diagrams and timing diagrams to manage channel changes, data transmission, and synchronization through frequency hopping, ensuring robust communication by maintaining multiple connections and retransmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel hopping is implemented for frequency diversity, then communication reliability is improved, but synchronization complexity increases
Solution Approach 1:
The system pre-establishes multiple synchronization channels and timing reference patterns before communication begins. Infrastructure nodes pre-synchronize with multiple leaf nodes across different channels, so that when channel hopping occurs, synchronization information is already available without requiring complex real-time resynchronization
Solution Approach 2:
The system implements feedback mechanisms where infrastructure nodes continuously monitor synchronization status across multiple channels and dynamically adjust timing references. Leaf nodes provide feedback about their synchronization state, enabling the infrastructure node to maintain accurate timing information as channels change
2Reliability
If redundant connections are established between infrastructure nodes and leaf nodes, then data transmission reliability is improved, but system complexity increases
Solution Approach 1:
The system segments the redundant communication paths into distinct logical layers: timing synchronization channels separate from data transmission channels. Each infrastructure node maintains redundant connections to multiple leaf nodes, but these connections are organized into functional groups (synchronization group vs. data group), simplifying the management of redundancy
Solution Approach 2:
Infrastructure nodes are designed with multi-functionality, serving both as synchronization sources and data transmission nodes simultaneously. The same physical infrastructure nodes perform multiple roles, reducing the need for separate dedicated redundant components and simplifying the overall system architecture
3Stability of the object's composition
If timing synchronization is maintained across channel changes, then communication stability is improved, but transmission time increases
Solution Approach 1:
The system implements periodic timing synchronization bursts at predetermined intervals during channel hopping sequences. Instead of continuous synchronization adjustments, timing references are updated periodically at known transition points, maintaining stability without requiring constant time investment
Solution Approach 2:
Timing synchronization information is prepared and buffered in advance before channel changes occur. Infrastructure nodes pre-calculate timing references for upcoming channel transitions, so that when the actual channel change happens, synchronization can be applied immediately without time-consuming real-time adjustments

AI summary
A wireless system having an infrastructure node and several leaf nodes in a non-redundant version or having at least two infrastructure nodes and several leaf nodes in a redundant version. Leaf nodes may individually seek out timing information in order to be in synch with an infrastructure node. Upon receipt of synch information from an infrastructure node, the respective leaf node may send data to the infrastructure node. In the case of a redundant system, primary and secondary nodes may be selected from a list of infrastructure nodes. Communications between an infrastructure node and a leaf node may occur on one of a number of channels, and the channel may be changed for communications between the nodes. In the case of a redundant system, a single transmission from the leaf node is received simultaneously by the redundant infrastructure nodes.
