PUTTING IT INTO PRACTICE
Shannon Channel Capacity: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Bandwidth (Hz) | 1,000,000 |
| Linear signal-to-noise power ratio | 15 |
| Result | 4,000,000 bits/s |
- Check the input labels and enter the example values above.
- Apply the relationship: Ideal capacity = bandwidth × log₂(1+SNR).
- The result is 4,000,000 bits/s, rounded for display.
How to interpret your result
Ideal additive-white-Gaussian-noise channel bound, not an actual network speed prediction.
Bits and bytes differ by eight. Average request rate can hide peaks and concurrency. A packet’s serialization delay is only one part of end-to-end network latency.
Frequently asked questions
Does serialization delay equal network latency?
No. Propagation, queuing, processing, framing and other paths can add to total latency.
When is the shannon channel capacity calculator useful?
Estimate the Shannon capacity bound for a bandwidth and linear SNR assumption. Ideal additive-white-Gaussian-noise channel bound, not an actual network speed prediction.
How do I use the shannon channel capacity calculator?
Enter bandwidth (hz), linear signal-to-noise power ratio. The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Ideal capacity = bandwidth × log₂(1+SNR).
What should I check before using the result?
Ideal additive-white-Gaussian-noise channel bound, not an actual network speed prediction.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
