1. A system for communicating within a borehole using controlled vibrations, comprising:

  • a movement mechanism configured to use mechanical energy provided by a mechanical energy source to enable translational movement of a first surface relative to a second surface to allow the first surface to repeatedly impact the second surface to produce a plurality of vibration beats, wherein the plurality of vibration beats will occur whenever the mechanical energy is provided by the mechanical energy source at one of at least three impact levels; and

    a vibration control mechanism configured to selectively control an amplitude of the plurality of vibration beats to encode information therein, wherein the amplitude of a vibration beat is selectively controlled by regulating the impact of the first surface and the second surface to one of the at least three impact levels.
