Large-capacity long-distance wireless mm-wave signal delivery at W-band

We overview our several field trial demonstrations of large-capacity long-distance wireless millimeter-wave (mm-wave) signal delivery at W-band based on some enabling technologies and advanced devices. First, we demonstrated up to 1.7-km wireless delivery of 20-Gb/s polarization-division-multiplexing quadrature-phase-shift-keying (PDM-QPSK) signal at W-band, which, to the best of our knowledge, is the longest wireless transmission distance for W-band signal delivery up to now. Then, we demonstrated 300-m wireless delivery of 80-Gb/s PDM-QPSK signal at W-band. 80Gb/s, or 74.7Gb/s after removing 7% forward-error-correction (FEC) overhead, is a record for W-band wireless signal delivery over a few hundred meters to the best of our knowledge. We also demonstrated 100-m wireless delivery of 100-Gb/s QPSK signal at W-band, which, to the best of our knowledge, is the highest baud rate at W-band with ~100m wireless distance.
