Systems and methods for duplex communication

A communication device comprising:

• a first extremely high frequency (EHF) communication unit configured to transmit and receive EHF signals, wherein the first EHF communication unit comprises:
• a transceiver configured to receive and demodulate an inbound EHF signal into an inbound time-compressed signal, and to receive and modulate an outbound time-compressed signal into an outbound EHF signal;
• and
• an antenna coupled to the transceiver configured to receive the outbound EHF signal from the transceiver and transmit the outbound EHF signal, and to receive an inbound EHF signal and provide the inbound EHF signal to the transceiver;
• a first data signal line configured to carry a data signal conforming to a first communication protocol;
• and
• a first protocol bridge element coupled to both the first data signal line and the first EHF communication unit, and configured to:
• receive a first protocol-compliant data signal from the first data signal line, translate the first protocol-compliant data signal to an outbound binary signal, time-compress the outbound binary signal, and transmit the outbound time compressed signal to the transceiver;
• and
• receive the inbound time-compressed signal from the transceiver, time decompress the inbound time-compressed signal to an inbound binary signal, translate the inbound binary signal to conform to a second communication protocol, and provide a second protocol-compliant signal to the first data signal line.
