Overview
Channel capacity is a concept in digital communication, which describes the maximum rate of information that can be reliably transmitted over a communication channel, such as a wire or a wireless link. It is one of the fundamental concepts in communication theory, as it provides a way of understanding the performance of a network or communication system when it is subjected to various conditions, such as noise and interference. Channel capacity is important for designing efficient communication systems, in order to ensure they are capable of reliably transferring data at the highest possible rate, while maintaining a low error rate. It is also used in wireless networks, such as Wi-Fi and cellular networks, in order to optimize data throughput and user experience.
