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 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.

E-Book Section Chapter 1: Decibels, Can You Hear Me Now?

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

You have probably heard of decibels, in the context of loud noises, rock concerts and similar. Decibels are also used in a radio context, and have a very similar meaning. In this case, the frequencies used are far beyond what humans can perceive – but the concept is the same, it represents “how loud is the signal from the other end?” Much of the content later-on requires that you understand decibels, so this section explains them to you.
