Shannon Channel Capacity

Calculate the theoretical AWGN channel-capacity bound from bandwidth and signal-to-noise ratio.

Inputs

Inputs

Range: 0.001–100,000 MHz

Enter channel bandwidth in MHz. The result is an ideal AWGN bound, not a channel allocation or throughput guarantee.

Range: -30–100 dB

Enter signal-to-noise ratio in dB at the receiver for the same bandwidth.

Result

AWGN channel-capacity bound (Mbit/s)
133.164
