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:
“and men strive with each other not for power or the accumulation of paper
but in joy create for others the house, the poem, the game of
athletic beauty.
Then washed in the brightness of the vision,
I saw how in its radiance would grow and be nourished and suddenly
burst into terrible and splendid bloom
the blood-red flower of revolution.”
—Dudley Randall (b. 1914)
“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)
