Frequency Hopping Transceiver Adaptive Noise Thresholding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The set of usable frequencies in frequency avoidance networks varies significantly over time, causing fluctuations that can disrupt data transmission between transceivers.
Innovation Solution
A method where a master transceiver analyzes the frequency plan, determines the minimum noise level, and iteratively adjusts comparison thresholds to ensure a stable set of usable frequencies, regularly updating and broadcasting these frequencies to maintain consistent data transmission.

1Reliability
If the set of usable frequencies is regularly updated to adapt to changing conditions, then the transmission reliability is improved, but the fluctuations in usable frequencies increase causing transmission disruptions
Solution Approach 1:
The patent applies dynamics by making the frequency determination adaptive rather than static. The master transceiver continuously monitors the frequency plan and dynamically adjusts the set of usable frequencies based on current noise conditions, allowing the system to adapt to changing environmental conditions while maintaining stable transmission through controlled update mechanisms
Solution Approach 2:
The patent implements feedback by having the master transceiver continuously monitor the frequency plan and use this information to update the set of usable frequencies. The measured noise levels feed back into the frequency selection process, allowing the system to respond to changing conditions while the broadcasting mechanism ensures all transceivers receive consistent frequency information

AI summary
The invention relates to a method for determining a set of frequencies that can be used in a frequency plane for transmitting information between at least two transceivers of a network operating with frequency hopping, which includes a step of initially determining an initial set of frequencies that can be used, each one of which has a magnitude lower than a threshold, at least one step (210, 220) of monitoring first and second portions of the frequency plane, the first monitored portion comprising the previously determined set of frequencies that can be used, the second monitored portion comprising frequencies that do not belong to the previously determined set of frequencies that can be used, and at least one step (230) of subsequently determining a new set of frequencies that can be used. The monitoring (210, 220) and subsequent determination (230) steps are performed automatically by a transceiver. The subsequent determination step associated with the first monitored portion has a first threshold, and the subsequent determination step associated with the second monitored portion has a second threshold which is separate from the first threshold.
