“…When an antenna gain of 35 dBi corresponds to a 3-dB beamwidth of 1.2 o even at a frequency of 85 GHz, the 25 m/s wind speed in a typhoon situation degrades the link gain by 3 dB or more via antenna misalignment owing to the inclination of the pole, which suggests that the antenna gain should be designed based on the location where the antennas are installed (Fig. 9) [54]. Moreover, the radome shape of the antenna should be optimized to avoid wind pressure, which induces inclination.…”

“…In other words, by reconstructing network telemetry technology, which conventionally obtains and aggregates traffic information from wired networks, with the FWS information, transparent network control can be realized in fixed-wireless and optical integrated networks. By developing a seamless optical-wireless convergence that includes the network control [54] layer and the physical layer described thus far, a highly effective network can be realized. As based on the discussion above, the civil engineering of the pole set with the antenna plays an important role in network construction.…”

Seamless conversion techniques between terahertz radio and optical fiber communication systems are in high demand for future access networks with a low carbon footprint. Radio-over-fiber technologies are a promising solution for realizing conversion in the millimeter-wave and terahertz bands using advanced optical modulation and photodetection devices. Herein, we briefly introduce radio-over-fiber technologies that enable applications to access networks in the seventh-generation mobile (7G) system era. Low-noise and high-frequency oscillator configurations using photonics, which are utilized in terahertz transceivers, are also investigated. A future system integrated with fixed wireless terahertz radio is discussed concerning geographical issues under severe weather conditions.

5G wireless systems will extend mobile communication services beyond mobile telephony, mobile broadband, and massive machine-type communication into new application domains, namely the so-called vertical domains including the smart factory, smart vehicles, smart grid, smart city, etc. Supporting these vertical domains comes with demanding requirements: high-availability, high-reliability, low-latency, and in some cases, high-accuracy positioning. In this survey, we first identify the potential key performance requirements of 5G communication in support of automation in the vertical domains and highlight the 5G enabling technologies conceived for meeting these requirements. We then discuss the key challenges faced both by industry and academia which have to be addressed in order to support automation in the vertical domains. We also provide a survey of the related research dedicated to automation in the vertical domains. Finally, our vision of 6G wireless systems is discussed briefly.
