1. A device for transmitting and receiving, the device comprising:

  • an antenna;

    a transmitting/receiving unit for transmitting and receiving data according to a communication standard, the transmitting/receiving unit including a transmission unit connected to the antenna for transmitting first data frames to a second transmitting/receiving device, the transmitting/receiving unit including a receiving unit connected to the antenna for receiving second data frames from the second transmitting/receiving device; and

    a control unit connected to the transmitting/receiving unit for controlling the transmitting/receiving unit, the control unit being configured to instruct the transmitting/receiving unit to transmit a first data frame and to receive a second data frame from the transmitting/receiving unit;

    wherein the transmitting/receiving unit has a controller, which is connected to the receiving unit and the control unit, and evaluates a second data frame received by the receiving unit within a predefined time interval after transmission of the first data frame and determines whether the second data frame contains an acknowledgment message for a successful receipt of the first data frame by the second transmitting/receiving device and to relay the second data frame to the control unit only if it is determined that it does not contain the acknowledgment message in order to reduce power requirements of said control unit when said second data frame contains an acknowledgement message.
