Demand for wireless services is increasing rapidly, due to deep penetration of mobile terminals, such as smartphones. Radio spectrum congestion is an important issue, even for conventional mobile services. One of the possible solutions would be to use wired and wireless seamless networks consisting of radio and optical links, where huge data traffic can be offloaded from radio-waves in the air to optical signals over fibres. This paper provides seamless network configurations which can be applied to 90-GHz high-speed wireless links and high-resolution radars. We focus on applications for public transportation systems including airport runways, railways, etc.

Radio links using terahertz (THz) waves can provide high-speed wireless transmission whose bitrate is higher than 100Gb/s. Congestion of radio spectrum in THz bands (0.1-10 THz) is not so significant for the time being. However, multilevel modulation formats would be required in in THz bands as well as in conventional millimeter-wave or microwave bands, to increase spectral efficiency. We provide overviews on spectral efficiency and transmission capacity of high-speed radio links using THz bands. Reduction power consumption in radio equipment is also very important to reduce operation cost of networks. We describe a survey result on power consumption of short-distance wireless systems. The result implies that THz high-speed radio links would be useful to reduce power consumption per bit in transmission. However, transmission distances in THz systems would be shorter than a few kilometers due to attenuation in the air. Thus, we should rely on seamless networks consisting of THz radio-links and optical fibers, where devices developed for optical fiber transmission can be used to THz wave generation and detection.
