The Shannon-Hartley Theorem

The Shannon-Hartley Theorem describes the maximum rate at which information can be reliably transmitted over a communication channel, such as a wire or wireless link. It states that this maximum data rate depends on the channel's bandwidth (the range of frequencies available) and its signal-to-noise ratio (how strong the signal is compared to background noise). Specifically, increasing the bandwidth or improving the signal quality allows for higher data transfer rates. This theorem helps engineers design communication systems to efficiently transmit information within the physical limits of the medium.
