E-Book Section Chapter 4: Noise Floor and Interference

Author: Herbert Wolverson, Posted: Tuesday, 04-14-15

Noise Floor (the amount of background noise affecting your link\\\'s frequency), and Interference (sources of noise on your channel) can greatly affect link performance. As we discussed in the Shannon-Hartley section, a link is only as good as the difference between the noise floor and the signal strength (SNR).

E-Book Section Chapter 2: Efficiency: Combining Data-Rates with the Shannon Formula

Author: Herbert Wolverson, Posted: Tuesday, 04-14-15

By combining the 802.11X standards for data-rate encoding over multiple spatial streams with the Shannon formula, it is possible to gauge the relative efficiency of the 802.11X protocols, and to see how much room for improvement remains to be squeezed out of future products.

E-Book Section Chapter 1: The Shanon-Hartley Theorem

Author: Herbert Wolverson, Posted: Tuesday, 04-14-15

The Shannon-Hartley theorem specifies the maximum amount of information that can be encoded over a specified bandwidth in the presence of noise. It serves as an upper ceiling for radio transmission technologies. Understanding how this relates to signal-to-noise ratio can help you understand how much bandwidth it is possible to obtain over a wireless link.
