In telecommunication, the term RF power margin has the following meanings:
- The amount of transmitter power above that which is computed by the link designer as the minimum required to meet specified link performance. The RF power margin allows for uncertainties in (a) empirical components of the signal level prediction method, (b) terrain characteristics, (c) atmospheric conditions, and (d) equipment performance parameters.
- At any given time in an operational link, the reserve transmitter power over that which is required to maintain specified link performance.
Famous quotes containing the words power and/or margin:
“The power of a text is different when it is read from when it is copied out.... Only the copied text thus commands the soul of him who is occupied with it, whereas the mere reader never discovers the new aspects of his inner self that are opened by the text, that road cut through the interior jungle forever closing behind it: because the reader follows the movement of his mind in the free flight of day-dreaming, whereas the copier submits it to command.”
—Walter Benjamin (1892–1940)
“Will not a tiny speck very close to our vision blot out the glory of the world, and leave only a margin by which we see the blot? I know no speck so troublesome as self.”
—George Eliot [Mary Ann (or Marian)
