English (EN)The reduction in signal intensity of one or several of the components of a radio signal, typically caused by the reflective or refractive effects of multi-path.
A form of conditioning that reduces the frequency distortion or phase distortion, or both, in an electrical signal on a metallic conductor or in a radio signal traveling through the atmosphere.
The difference between the time of arrival of the earliest significant multipath component (typically the line-of-sight component) and the time of arrival of the latest multipath component.
The wireless RF-based portion of a network providing access from a mobile terminal device (transmitter/receiver) to the core, or backbone, network of the radio service provider.
The functions defining all aspects of network signaling and control, such as call control and connection control.
