What is the relationship between frequency and distance?

In general, yes, higher frequencies attenuate more the further distance they travel. There are two effects that are responsible for this. First, higher frequency radio waves tend to be absorbed more readily by objects (ie: the penetration depth in the material is shorter).

What is the relationship between frequency and the distance in electromagnetic wave propagation?

Based on the relation between frequency and wavelengths, the higher the frequency, the shorter the wavelengths and therefore the distance of travel is lower. Assuming two frequencies from the ISM band: 2.45 GHz and 5.8 GHz.

What is the relationship between carrier frequency and the signal bandwidth?

Carrier frequency and bandwidth are two different characteristics of an RF signal. A simplified description is that the carrier is the frequency of the un-modulated RF signal. Bandwidth is the spectrum above and below the carrier frequency which contains signal components due to modulation of the carrier.

What is meant by carrier frequency?

The proportion of individuals in a population who have a single copy of a specific recessive genetic variant. Carrier frequency also sometimes refers to the prevalence of variants in dominantly acting genes, such as BRCA1 and BRCA2. Also called carrier rate.
