Abstract
This research paper delves into the level of development and advantages of application of telecommunication systems of terahertz range (100GHz to 3000GHz), including the fields of application for the developed technologies as well as the outstanding problems and feasible methods of their solution. Unfortunately, the frequency resource of the currently used radio-frequency band is physically incapable of transmitting very high-speed and high-speed data torrents via a radio channel. The application of multilevel modulations that could allow for the increase in speed is rather limited whereas the application of higher frequencies allows for the use of broader frequency band to transfer the gigabit torrents. This innovative approach has many advantages, in particular, confidentiality of data transmission and narrow-beam radio emission. This paper also gives examples of available systems using the state-of-the-art semiconductor CMOS, SiGe and GaAs technologies and it also describes their specific features.
KEY WORDS: terahertz range, radio channel, telecommunication system gigabit data flow, semiconductor and nanotechnologies
