UAVs offer the capability to enhance coverage and bridge connectivity gaps in underserved regions, establishing line-...

Free space optical (FSO) systems, due to their large bandwidth and secure and cost-efficient data transmission, are considered as suitable candidates for next generation wireless communication networks and beyond. However, they require a line-of-sight (LOS) connection between transmitter (Tx) and re...

Free space optical (FSO) systems, due to their large bandwidth and secure and cost-efficient data transmission, are considered as suitable candidates for next generation wireless communication networks and beyond. The point-to-point FSO channel requires a line-of-sight (LOS) link, which can be relax...

The Coordinated Research Center "Empatho-Kinaesthetic Sensory Systems" (EmpkinS) is working on the development of wearable sensors with limited size for non-invasive detection of biomedical processes. Wireless power transfer (WPT) is a promising technique that enables efficient remote recharging of ...

The substantial growth of the number of Internet-of-Things (IoT) devices in the recent years has motivated the research on the optimal design of far field wireless power transfer (WPT) systems, which enable efficient recharging of the batteries of small low-power devices. To increase the amount of p...

Recent advances in the drone industry have led to increased interest in using unmanned aerial vehicles (UAVs) for wireless communication purposes. However, limited power remains the big issue, as in such missions, endurance is of paramount importance. In this context, free-space optics (FSO) seems to not only offer a way to transfer high data rates but also a key technology to provide energy to flying platforms.

Molecular communications (MC) is an emerging communications approach with many interdisciplinary applications in industry and medicine. MC can be used in environments, where classical communication using electromagnetic waves is not feasible. Applications of particular interest are infrastructure mo...

Free space optical (FSO) systems due to their large bandwidth, secure and cost-efficient data transmission are considered as suitable candidates for next generation wireless communication networks and beyond. However, the limiting factor in such systems is the requirement of a line-of-sight (LOS) li...

Recently, the application of communication engineering principles to biomedical problems has spawned the emerging interdisciplinary research field of molecular communication (MC). MC is ubiquitous in natural biological systems and has a high potential for bio-medical applications such as targeted dr...

The design of communication networks for nanodevices, so-called nanonetworks, has gained a lot of attention. Nanonetworks could enable exciting new applications in biomedicine, environmental monitoring, and manufacturing. Molecular communication (MC), i.e., the exchange of information via molecules, is a bio-hybrid approach to nanonetwork design.
