GHz-to-THz broadband communications for 6G non-terrestrial networks

A Wireless Broadband Integrated Services Communications System at 60 GHz *

The paper presents a wireless integrated services communications system for indoor and campus use. Whereas most current indoor wireless systems are distinct solutions for different services, our network, WISCS, covers the entire range from low-rate mobiles to high-speed portables. The system employs a picocellular structure in the 60 GHz band to provide capacity demanded by broadband services. ...

High-speed supercomputer communications in broadband networks

High speed communication across wide area networks is currently of great interest in computer communications industry. It is needed wherever a huge amount of data will be created and made available to remote computer systems. Areas of investigation in computer science are the coupling of supercomputers (metacomputing), high-resolution visualisation of data and distributed access to huge amounts...

Broadband Communications from Aerial Platform Networks

Provision of broadband services is raising increasing challenges, particularly in operating environments requiring wireless access. In this context an emerging solution based on aerial platforms is attracting increasing amounts of research effort. This concept combines some of the best characteristics of terrestrial and satellite communication systems, and it provides alternative and complement...

Broadband semiconductor superlattice detector for THz radiation

We report on a broadband GaAs/AlAs superlattice detector for THz radiation; a THz field reduces the current through a superlattice, which is carried by miniband electrons, due to modulation of the Bloch oscillations of the miniband electrons. We studied the detector response, by use of a free electron laser, in a large frequency range ~5–12 THz!. The responsivity showed strong minima at frequen...
