Abstract: A system comprises a decision logic module, a payload IC, an optical transceiver, a mmWave transceiver, and an antenna array. The decision logic module evaluates channel conditions and selects one of four transmission modes based on a signal quality indicator. The payload IC generates baseband data and receives demodulated data. The optical transceiver, coupled to the decision logic and payload IC, transmits and receives optical signals via a free-space link using either a first or second modulation format. The optical array handles optical signal emission and reception. The mmWave transceiver, coupled to the decision logic and payload IC, transmits and receives mmWave signals via a free-space mmWave link using a third or fourth modulation format. The antenna array supports mmWave emission and reception. The first modulation format offers higher spectral efficiency than the second. The third provides a higher data rate than the fourth under favorable signal-to-noise conditions.
