Definition: Timbre is the unique quality of an instrumentâs sound; its âvoice.â. Timbre describes the difference between two tones played in the same pitch and volume.
Cell site placed atop an existing building. A cell site or cell tower is a cellular telephone site where antennae and electronic communications equipment are placed, usually on a radio mast, tower or other high place, to create a cell (or adjacent cells) in a cellular network.
The cell phone needs much less power essentially because: The receiver on top of the cell tower affords to be much more sensitive than the receiver you can cram inside a mobile phone. (this accounts for most of the difference in needed output power on both sides) It transmits on a slightly lower frequency band, thus bearing a slightly lower propagation loss. (some 2dB, you'd make do with 2/3 of the power)
