An automatic gain control provides for enhanced acquisition and tracking
of wireless signals. The wireless signals may include signals using
electrostatic fields, magnetic fields, or electromagnetic fields. In an
embodiment, wireless signals are provided as radio frequency signals. The
automatic gain control design is intended to quickly acquire new incoming
information in a wireless signal. A control unit regulates the automatic
gain control to manage the acquisition and gain of the wireless signal
based on a transmission protocol. The automatic gain control adjusts the
gain for the wireless signal to a minimal level required for detection
for a preprogrammed amount of time, at the same time minimizing unwanted
background noise from interfering with the data packet. When the
communication session is concluded, the automatic gain control can be
released allowing increased sensitivity in preparation of the next
transmission.
