Mobile Super-6GHz Directional Wireless Systems for 5G-and-Beyond

Murat Yuksel

University of Central Florida

Recent proliferation of wireless technologies and choices available to user applications have triggered a tremendous wireless demand, and the wireless nodes are expected to dominate the Internet for the foreseeable future. Accommodating this exploding wireless demand with the legacy cellular capacity does not seem possible in the long run. As the sub-6GHz radio frequency (RF) spectrum is getting scarcer and saturated by recent innovations in attaining high spectral efficiency gains, we urgently need innovations that will enable leveraging of new wireless spectrums and substrates to respond to the exploding mobile wireless traffic demand. Further, the capacity gap between RF wireless and optical fiber backbone speeds will remain huge because of the limited availability of RF spectrum. This gap in the “last mile” of the Internet is getting more troublesome as smart Internet-of-Things (IoT) is becoming a reality and more things around us need wireless connectivity. Enabling super-6GHz (millimeter-wave, optical, and terahertz) spectrum in wireless communications is the needed revolution for high-speed mobile networks of the future.

Towards 6G: New Dimension of Wireless Transmission with Orbital Angular Momentum

Chao Zhang

School of Aerospace Engineering, Tsinghua University, Beijing, China

As the independent physical resource in Electro-Magnetic (EM) wave, Orbital Angular Momentum (OAM) can provide the new dimension for wireless transmissions, which serves as one of the potential key technologies for future wireless communications, e.g. 6G mobile communications. With the exhaustion of frequency resources, the revolutionary multiplexing scheme with higher spectrum efficiency based on OAM is expected. To be specific, the definitions of OAM with regard to the quantum OAM vortex EM wave and statistical OAM vortex beam are quite different, which belongs to the intrinsic and extrinsic OAMs, respectively. Consequently, the extrinsic OAM in the statistical OAM vortex beam is strongly coupled to the space domain of the electric field strength, which is the fundamental reason for the statistical OAM vortex beam transmission not exceeding the capacity bound of the conventional MIMO transmissions. In contrast, the intrinsic OAM in the quantum OAM transmission system is physically independent of the electric field strength and decoupled from the macroscopic space domain, constituting the new independent dimension of wireless transmissions. Therefore, the quantum OAM vortex EM wave with intrinsic OAM is a future direction for developing new resources of EM waves, as well as the potential key technology in the corresponding wireless communication systems. The quantum OAM transmission with the vortex microwave photons has the potential to surpass the traditional MIMO capacity bound with multiple antennas. Recently, Communications Engineering, the academic journal issued by Nature Publication Group, has published the article on the experiment of the quantum OAM wireless transmission, which demonstrates the potential of new dimension with OAM. In this keynote, the concept of OAM, the latest research progress of OAM, and the potential applications of OAM will be highlighted and discussed.

OCC, from IoT to Internet of Behavior

Prof. Rafael Pérez-Jiménez

University of Las Palmas de Gran Canaria, Spain

Ubiquitously present Cameras can have a dual use as image sensors and OCC technologies receivers for IoT. This unique characteristic opens a new frame for several applications where, obviously, privacy and data protection must be a central aspect in the design of those solution. It can be applied to environments such as nursing homes or civic centers, hospitals, shopping centers, open shopping areas or even any residential area with peripheral delimitation. OCC networks makes possible to combine the use of systems based on visible or infrared light, maintaining their advantages with the use of low-cost receivers, which allow their integration in a mobile communications device as a regular App. From a holistic point of view, IoT should be considered as a part of the integration, communication, location and sensing strategies to obtain a portrait of the behavior of the user, in some specific scenarios as could be museums or hotels following the SoLoMo paradigm for tourism destinations.
