Since at least the 1990s, scientists have researched whether the now-ubiquitous radiation associated with mobile phone antennas or cell phone towers is affecting human health. [ 1] Mobile phone networks use various bands of RF radiation, some of which overlap with the microwave range. Other digital wireless systems, such as data communication ...
Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.. Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communication channel) will vary randomly, or fade, according to a Rayleigh distribution — the radial component of the sum of ...
Communication studies, also referred to as communication science, is the academic discipline studying communication. It is closely related to semiotics, with one difference being that communication studies focuses more on technical questions of how messages are sent, received, and processed.
Punch, 25 February 1914.The cartoon is a pun on the word "Jamaica", which pronunciation [dʒəˈmeɪkə] is a homonym to the clipped form of "Did you make her?".

For example, disability may be seen as a result of bad actions of parents if congenital, or as a result of practicing witchcraft if not. [47] Echoes of this can be seen in the doctrine of karma in Eastern and New Age religions. It also includes notions that a disability gives a person "special abilities to perceive, reflect, transcend, be ...
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or a material medium. [ 1][ 2] This includes: electromagnetic radiation consists of photons, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) particle radiation consists of ...
Communication ethics. Communication ethics is a sub-branch of moral philosophy concerning the understanding of manifestations of communicative interaction. [ 1] Every human interaction involves communication and ethics, whether implicitly or explicitly. Intentional and unintentional ethical dilemmas arise frequently in daily life.
