This tool will help you estimate your First Home Super Saver (FHSS) scheme’s potential savings.
How to use the FHSS Estimator
Fill in the details for the following fields:
- Number of Channels: The total number of frequency channels available.
- Dwell Time (ms): The time spent on each channel per hop in milliseconds.
- Hop Rate (hops/sec): The rate at which the system hops between channels.
- Channel Bandwidth (MHz): The bandwidth of each channel in megahertz.
- Available Bandwidth (MHz): The total available bandwidth in which the channels operate, in megahertz.
- Duty Cycle (%): The percentage of time the system is active.
Click “Calculate” to see the estimated occupancy of the system based on the provided parameters.
Calculation Method
The FHSS Estimator works by calculating the total time a frequency hopping system occupies a spectrum based on the number of channels, dwell time per channel, and hop rate. This is then adjusted by the duty cycle and the bandwidth to provide an estimation of spectrum occupancy.
Formula:
Occupancy = ((Number of Channels / Hop Rate) * Dwell Time * Duty Cycle * Channel Bandwidth) / Available Bandwidth
Limitations
Please note that this calculator provides an estimation and may not account for all factors influencing actual spectrum occupancy. It assumes idealized conditions and uniform distribution across all channels. Actual performance may vary based on interference, channel overlap, and other real-world conditions.

Estimating Frequency Hopping Spread Spectrum (FHSS) with FHSS Estimator
With the FHSS estimator, you can accurately estimate the frequency hopping spread spectrum (FHSS) parameters of a given signal. This tool helps you determine the exact frequency bands that are used by the FHSS signal for optimal performance.
Calculating Hop Interval
By inputting the number of hops and the total time taken for these hops in the FHSS estimator, you can quickly calculate the hop interval of the FHSS signal. This information is crucial for understanding the hopping pattern and timing.
Measuring Hopping Rate
Estimate the hopping rate of an FHSS signal by providing the total number of hops and the duration over which these hops occur. The FHSS estimator will give you the precise value, helping you assess the speed at which frequency transitions take place.
Identifying Carrier Frequencies
Use the FHSS estimator to determine the carrier frequencies employed in an FHSS system. By entering the frequencies corresponding to each hop, you can easily identify the distinct carriers used in the spread spectrum signal.
Monitoring Dwell Time
Track the dwell time of each frequency within an FHSS signal using the FHSS estimator. By inputting the time spent on each hop, you can analyze how long the system stays on particular frequencies during operation.
Analyzing Frequency Bandwidth
Get insights into the frequency bandwidth used by the FHSS signal with the FHSS estimator. By specifying the start and end frequencies of the hopping range, you can calculate the overall bandwidth occupied by the signal.
Optimizing Frequency Allocation
Optimize the allocation of frequencies in your FHSS system by utilizing the FHSS estimator. By analyzing the distribution of carrier frequencies and their intervals, you can fine-tune the hopping sequence for maximum efficiency.
Verifying Coexistence with Other Systems
Assess the compatibility of your FHSS system with other wireless systems by utilizing the FHSS estimator. By examining the hopping patterns and frequency ranges, you can ensure smooth coexistence without interference.
Estimating Channel Capacity
Determine the channel capacity of your FHSS system by inputting the hop interval and bandwidth into the FHSS estimator. This calculation helps in assessing the maximum data rate that can be supported by the system.
Calculating Synchronization Accuracy
Evaluate the synchronization accuracy of your FHSS system by analyzing the hopping rate and timing parameters using the FHSS estimator. This information is crucial for maintaining reliable communication and minimizing synchronization errors.
