What is the meaning of channel capacity?

The channel capacity, C, is defined to be the maximum rate at which information can be transmitted through a channel.

What is bandwidth and channel capacity?

Channel capacity (bandwidth)

Channel capacity is a maximum information rate that a channel can transmit. It is measured in bits per second (bps). Channel capacity is a rough value as measuring takes into account only the whole amount of data transferred, but leaves out of account communication quality.

How is channel capacity measured?

The capacity of the binary symmetric channel is C = 1 − H(p) bits per transmission, and the capacity of the binary erasure channel is C = 1 − α bits per transmission.

Why is channel capacity important?

The channel capacity is an extremely important quantity, since it is possible to transmit information through a channel at any rate less than the channel capacity with an arbitrary small probability of error; completely reliable transmission is not possible if the information processed is greater than the channel ...

How can I increase my channel capacity?

According to the equation, the only way to increase the channel capacity is to either increase the bandwidth or increase the SNR.
