The power supplied to an antenna multiplied by the antenna gain in a given direction. Note 1: If the direction is not specified, the direction of maximum gain is assumed. Note 2: The type of reference antenna must be specified. 2. The product of the power supplied to the antenna and its gain relative to a half-wave dipole in a given direction. Note: If the direction is not specified, the direction of maximum gain is assumed. 3. The effective radiated power of a transmitter (with antenna, transmission line, duplexers, etc. ,) is the power that would be necessary at the input terminals of a reference half-wave dipole antenna in order to produce the same maximum field intensity. ERP is usually calculated by multiplying the measured transmitter output power by the specified antenna system gain, relative to a half-wave dipole, in the direction of interest.
Industry:Telecommunications
The power output of a radio transmitter under stated conditions of operation and measurement. Note: Power output ratings may be made against a number of criteria, e.g., peak envelope power, peak power, mean power, carrier power, noise power, or stated intermodulation level.
Industry:Telecommunications
The power of one of two equal tones that, when used together to modulate a transmitter, cause it to develop its full rated peak power output.
Industry:Telecommunications
The power loss that occurs when an optical signal is transferred from one fiber to another that is axially aligned with it, but longitudinally separated from it. Note: The gap allows light from the "transmitting" fiber to spread out as it leaves the fiber endface. When it strikes the "receiving" fiber, some of the light will enter the cladding, where it is quickly lost. 2. An analogous form of coupling loss that occurs between an optical source, e.g., an LED, and an optical fiber. Note: Gap loss is not usually significant at the optical detector, because the sensitive area of the detector is normally somewhat larger than the cross section of the fiber core. Unless the separation is substantial, all light emerging from the fiber, even though it diverges, will still strike the detector. Synonym longitudinal offset loss.
Industry:Telecommunications
The power in dBm of a speech signal measured using a technique equivalent to Method B of ITU-T Recommendation P. 56.
Industry:Telecommunications
The power granted an Administration, or its designated or delegated leader or agency via treaty or law, to specify frequencies, or frequency bands, in the electromagnetic spectrum for use in systems or equipment. Note: Primary frequency assignment authority for the United States is exercised by the National Telecommunications and Information Administration (NTIA) for the Federal Government and by the Federal Communications Commission (FCC) for non-Federal Government organizations. International frequency assignment authority is vested in the International Frequency Registration Board of the International Telecommunication Union.
Industry:Telecommunications
The power generated by a random electromagnetic process. 2. Interfering and unwanted power in an electrical device or system. 3. In the acceptance testing of radio transmitters, the mean power supplied to the antenna transmission line by a radio transmitter when loaded with noise having a Gaussian amplitude-vs. -frequency distribution.
Industry:Telecommunications
The power consumed by a device or circuit in performing its function. 2. A power-consuming device connected to a circuit. 3. To enter data or programs into storage or working registers. 4. To insert data values into a database that previously contained no occurrences of data. 5. To place a magnetic tape reel on a tape drive, or to place cards into the card hopper of a card punch or reader.
Industry:Telecommunications
The potential for electromagnetic radiation to produce harmful biological effects in humans.
Industry:Telecommunications
The potential for electromagnetic radiation to cause ignition or detonation of volatile combustibles, such as aircraft fuels.
