Abstract: A wireless in-flight entertainment distribution apparatus distributes audio signals within an aircraft. A connector receives an audio signal that is converted to digital data words. The digital data words are then collected into groups to form data packets which then formed into data frames. Transmission channels are chosen to have at least one fundamental frequency which is then modulated with the data frames received. The modulated fundamental frequency is amplified to drive a transducer such as an antenna to generate a transmission signal through a transmission media. The wireless in-flight entertainment distribution system further receives the transmission signal from the transmission media. The transmission signal is then demodulated, depacketized, and decoded to recover the audio signal. The recovered audio signal is then transmitted to the speaker. The in-flight distribution apparatus adheres to the Bluetooth protocol for the transmission and reception of the digitized audio signal.
