This tool calculates the channel capacity according to the Shannon-Hartley theorem.

The capacity is expressed in terms of bits per second.

Enter:

**Signal-to-Noise Ratio**either as a linear or dB quantity.**Bandwidth**in Hz/kHz/MHz/GHz

**Formula**

**C = B*Log _{2}(1 + S/N)**

where,

**C**is the throughput in bits per second**B**is the bandwidth in Hz**S/N**is the signal-to-noise ratio

## Key Assumptions

The Shannon-Hartley formula makes the following assumptions:

- The noise is white Gaussian. In other words it does not consider the effect of Fading or external interference which can cause additional signal degradation.
- The throughput in bit-per-second is an
**upper bound**. It represents an ideal condition that can be achieved with an arbitrarily low error rate.

**Example Calculation**

For **5 MHz** of bandwidth and **10 dB **Signal to noise ratio, the maximum throughput is **17.3 Mbps**. Throughput increases with SNR. For instance at **15 dB SNR**, the max data rate is **25.14 Mbps**.
