Abbreviation for ultrawideband. 1. Referring to any radio or wireless device where the occupied bandwidth is greater than 25% of the center frequency or greater than 1. 5 GHz. 2. A radio or wireless system that uses narrow pulses (on the order of 1 to 10 nanoseconds,) also called carrierless or impulse systems, for communications and sensing (short-range radar. ) 3. A radio or wireless system that uses time-domain modulation methods (e.g., pulse-position modulation) for communications applications, or time-domain processing for sensing applications.

Ability of an entity to provide service within the required time. Note: The term timeliness is sometimes used incorrectly to mean responsiveness.

Industry:Telecommunications
Abnormal propagation caused by fluctuations in the properties (such as density and refractive index) of the propagation medium. Note: AP may result in the reception of signals well beyond the distances usually expected.
Industry:Telecommunications
Abrupt and unwanted variations of one or more signal characteristics, such as the interval between successive pulses, the amplitude of successive cycles, or the frequency or phase of successive cycles. Note 1: Jitter must be specified in qualitative terms (e.g., amplitude, phase, pulse width or pulse position) and in quantitative terms (e.g., average, RMS, or peak-to-peak. ) Note 2: The low-frequency cutoff for jitter is usually specified at 1 Hz. 2. Random variability of data pass-through time. See timing jitter.
Industry:Telecommunications
Absorption occurring as a result of interaction between an electromagnetic wave and free electrons in the ionosphere.
Industry:Telecommunications
Absorption of light energy by its conversion to vibrational energy. Note: Phonon absorption determines the fundamental, i.e., quantum limit of attenuation, i.e., minimum attenuation, in silica-based glasses in the far infrared region.
Industry:Telecommunications
ACC is a two-part feature. In order for ACC to function properly it must be implemented in the originating and terminating nodes of an interconnected network. The first part enables a (terminating) network node to alert interconnected nodes that it is in Machine Congestion 1 or 2 (MC1 or MC2. ) The second part allows a distant (originating) network node to automatically react to an ACC message and enact trunk group controls (CANT and SKIP) on specific trunk groups.
