Abstract
The drive-up station full duplex communication system is adapted for use in a building having a drive-up vehicle lane at the outside thereof, and having a customer speaker post at the lane for enabling a customer to communicate verbally with personnel within the building to enter into a transaction. A transceiver used by personnel to communicate with a customer via a base station, is disposed within the building includes a device for attenuating a received audio signal when an outgoing audio signal is being transmitted. A customer speaker post at the drive-up station includes a device for similarly attenuating the incoming audio signal when an audio signal is being transmitted to the transceiver unit disposed within the building. Full duplex communication is achieved while substantially decreasing or eliminating unwanted feedback interference at both units.
