Specific Hopping Patterns for Interference-Resilient Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems using time and/or frequency hopping patterns face reduced interference immunity when multiple nodes use the same patterns, leading to overlapping transmissions that can cancel each other out, and inefficiencies due to uniform pattern usage and quartz tolerance variations.
Innovation Solution
Implementing individual hopping patterns for each data transmitter and receiver, which are derived from operating parameters such as addressing information, radio cell, geographical location, QoS requirements, quartz tolerance, and energy availability, to reduce interference and optimize frequency usage.

Engineering Contradiction Analysis
1Ease of operation
If multiple nodes use the same global time and frequency hopping pattern for data transmission, then the system maintains simplicity in pattern definition and synchronization, but the interference immunity is reduced and transmission reliability deteriorates due to overlapping transmissions that can cancel each other out
Solution Approach 1:
The patent segments the single global hopping pattern into multiple individual hopping patterns, one for each transmitter. Each pattern is derived from a unique identifier (such as transmitter ID or addressing information), thereby dividing the unified pattern space into node-specific patterns that reduce collisions while maintaining systematic generation.
Solution Approach 2:
The patent applies local quality by making each hopping pattern specific to a particular transmitter's local characteristics (unique identifier, addressing information). This ensures that each node uses a hopping pattern tailored to its identity, reducing the probability of pattern collisions with other nodes while maintaining overall system coordination.
2Reliability
If individual hopping patterns are generated for each transmitter based on unique identifiers, then interference immunity is improved and pattern collisions are reduced, but the device complexity and computational overhead increase
Solution Approach 1:
The patent changes the parameter used for pattern generation from a single global seed to node-specific parameters such as transmitter ID, addressing information, or other unique identifiers. This parameter change enables individual pattern generation without requiring complex algorithms, as the patterns are derived systematically from the available identifier parameters.
Solution Approach 2:
The patent implements self-service by enabling each transmitter to autonomously generate its own hopping pattern using its unique identifier. This eliminates the need for centralized pattern distribution or complex coordination protocols, as each node independently derives its pattern from its own identifying parameters.
3Productivity
If a uniform hopping pattern is used across all nodes, then the network capacity is limited due to pattern collisions, but the system maintains lower complexity in pattern management and synchronization
Solution Approach 1:
The patent introduces dynamics by making the hopping pattern adaptable to each transmitter's characteristics. Instead of a static uniform pattern, the system dynamically assigns or derives patterns based on node identifiers, allowing the network to scale capacity as nodes are added while maintaining pattern uniqueness through systematic derivation.

AI summary
In exemplary embodiments, data transmitters and the data receiver use an individual hopping pattern for communication instead of a uniform (global) hopping pattern that is used in the same way by all data transmitters and data receivers in a communications system. Said individual hopping pattern can be dependent on an operating parameter and is thus used exclusively by the data transmitter and the data receiver or by a small group of data transmitters and/or data receivers, thereby making it possible to significantly increase immunity to disturbances.
