Towards Terahertz Communications Systems

Abstract

Within the wireless communications industry the pressure is on to provide ever more services such as e-mail, fast access to the World Wide Web and ultimately videophones. More and more people are requiring the ability to send and receive large documents and files from wherever they are in the world. As this demand increases it is likely that bandwidth is going to become an even more valuable commodity. There will be therefore an increase in the frequency used for communication and data transferral. This trend is already taking place with the point to point links required for LMDS moving to 40GHz. Whether there will ever be a need for even higher frequencies is unclear but this paper briefly investigates the feasibility of implementing terahertz wireless communication.
