This paper describes wired and wireless seamless networks consisting of radiowave and optical fiber links. Digital coherent technology developed for high-speed optical fiber transmission can mitigate signal deformation in radiowave links in the air as well as in optical fibers. Radio-over-fiber (RoF) technique, which transmits radio waveforms on intensity envelops of optical signals, can provide direct waveform transfer between optical and radio signals by using optical-to-electric or electric-to-optical conversion devices. Combination of RoF in millimeter-wave bands and digital coherent with high-performance digital signal processing (DSP) can provide wired and wireless seamless links where bit rate of wireless links would be close to 100 Gb/s. Millimeter-wave transmission distance would be shorter than a few kilometers due to large atmospheric attenuation, so that many moderate distance wireless links, which are seamlessly connected to optical fiber networks should be required to provide high-speed mobile-capable networks. In such systems, reduction of power consumption at media converters connecting wired and wireless links would be very important to pursue both low-power consumption and large capacity.
