Shannon builds on Nyquist. Nyquist doesn't really tell you the actual channel capacity since it only makes an implicit assumption about the quality of the channel.

"WebbMeaning of Shannon information capacity In electronic communication channels the information capacity is the maximum amount of information that can pass through a channel without error, i.e., it is a measure of channel “goodness.” The actual amount of information depends on the code— how information is represented.

Webb6 maj 2024 · For example, if a fiber plant costs US$4 million, the first gigabit may cost US$4 million, but when 9,600 Gbps is installed, the cost-per-gigabit drops to US$417 (Figure 1). This represents a linear decline in cost. That is until the capacity on a fiber can no longer increase due to Shannon’s Limit and spectrum availability.

Webb17 feb. 2015 · Shannon's formula C = 1 2 log (1+P/N) is the emblematic expression for the information capacity of a communication channel. Hartley's name is often associated with it, owing to Hartley's rule: counting the highest possible number of distinguishable values for a given amplitude A and precision ±Δ yields a similar expression C′ = log (1+A/Δ). During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the context of the telegraph as a communications system. At the time, these concepts were powerful breakthroughs individually, but they were not part of a comprehensive theory. In the 1940s, Claude Shannon developed the concept of channel capacity, based in part on the ideas of Nyquist and Hartley, and then formula…

WebbShannon limit. C = B log2(1+SNR) (4) The Shannon limit is a comprehensive relationship in that it takes into account three of the four most important parameters, the bandwidth, the carrier power and the noise level. It does not account for signal levels because it is already in terms of bits of information.
