Network evolution toward high frequency spectrum technologies such as millimeter wave and sub-terahertz not only quench the thirst for more communication bandwidth, but also for higher sensing fidelity. Integrated (joint) sensing and communication (ISAC) enable hardware and spectrum reuse between sensing and communication functions, allowing dual-function green networks to be built on cost-effective hardware. In the April issue of CTN, Profs. Kaushik, Eldar and Dobre take a multi-layer snapshot of this burgeoning area of research, highlighting impacts of emerging technologies such as reconfigurable intelligent (or holographic) surface, energy-efficient beamforming, and novel multiple access schemes. The multidisciplinary nature of ISAC is amply illustrated by the diverse applications it has found itself in, as well as the comprehensive up-to-date references. Read on, savor the prospect of novel applications that are emerging, and some that have not yet come to pass. As usual, your thou
For the last article of 2022 we are exploring yet another perspective on Non-Terrestrial-Networks. The last two months the authors explored some interesting applications of NTN based communications networks, this month the authors acknowledged the great potential that these networks, when paired with terrestrial networks can have, while at the same time providing a perspective regarding the type of technologies that are needed to make the deployment and overall performance of these “3D” networks as efficient and reliable as possible. Of particular interest is the subject of smart surfaces and what they can do to aid the overall performance of 3D networks. Smart surfaces (a.k.a. RIS) have been and will continue to be the subject of extensive research and debate with many challenges remaining in the quest for implementable solutions. In the end, there’s no debating that sky/space-based networks in their many forms are already here, and the industry will continue to address many ope
