Radio clock — A radio clock is a clock that is synchronized by a time code bit stream transmitted by a radio transmitter connected to a time standard such as an atomic clock. Such a clock may be synchronized to the time sent by a single transmitter, such as… … Wikipedia
ITU Model for Indoor Attenuation — The ITU Indoor Propagation Model, also known as ITU Model for Indoor Attenuation , is a radio propagation model that estimates the path loss inside a room or a closed area inside a building delimited by walls of any form. Suitable for appliances… … Wikipedia
Non-line-of-sight propagation — Non line of sight (NLOS) or near line of sight is a term used to describe radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Many types of radio transmissions depend, to… … Wikipedia
Affaiblissement de propagation — L’affaiblissement de propagation, aussi connu comme affaiblissement de parcours ou par son nom anglais de path loss, caractérise l affaiblissement que subit une onde électromagnétique lorsqu elle parcourt une distance.
