Broadband Wireless & Sensor Networks

The activities of AIT’s Broadband Wireless & Sensor Networks (B-WiSE) Research Group are directed towards the design, study and demonstration of smart, spectrally and energy-efficient wireless communications systems and networks that range from Body Area to Sensor to Wide Area and Satellite Networks. The B-WiSE group brings, through its members and alumni, a long industrial and academic experience in the development of advanced techniques and technologies for next generation communication systems and networks and a solid research background in a diverse number of scientific disciplines related to these fields. The group has hosted over three dozens of researchers and graduate students since its inception in 2002, comprises a Research Lab equipped with several wireless testbeds and software tools, including its own, is active in many research communities and the corresponding literature (with a large output of scientific journal / conference papers, books and book chapters), has ran and participated in several collaborative research projects (mostly funded from the European Commission but also via national and industrial grants), collaborates with a large number of Universities and companies, primarily in Europe, and has been internationally recognized via a number of honors and awards. Besides its active personnel, the B-WiSE group also hosts regularly research visitors, students and interns who participate in its research activities during short stays and collaborates with other AIT research groups on topics of mutual interest. It also hosts regularly invited speakers who give seminars on relevant research topics and participates in the organization of workshops and conferences in its fields of interest. The group’s moto is “Smart, Green, Wireless.”

B-WiSE is active in a number of research fields within its thematic range, such as: communication theory; signal processing techniques for communications; adaptive filtering and constrained optimization techniques; antenna design; multi-antenna / MIMO systems; Massive MIMO systems; cooperative wireless transmission; cm and mm wave communication; hybrid analog / digital (such as parasitic) antenna array systems, spectrum sensing and sharing techniques; licensed shared access (LSA); wireless channel modelling and estimation; positioning techniques; interference mitigation; resource allocation; cross-layer optimization; wireless networking; cognitive radio systems; mobile ad hoc, mesh and multihop networks; wireless access and backhaul networking; heterogeneous networks; hybrid terrestrial / satellite networks; wireless / wireline network integration; cloud-RAN; wireless caching techniques; green wireless networks; design and prototyping of novel antenna and other hardware modules; wireless testbed design and over-the-air (OTA) experimentation; wireless network security and policy reinforcement, etc. Capitalizing on its signal processing expertise, the group has also made contributions to other fields such as photonic systems and biomedical signal processing. The group is also interested in a number of emerging research areas such as batteryless / passive RFID technology, Terahertz wireless communication, visible light communication, quantum-enabled wireless transmission, etc.

The technologies described above address a large gamut of application domains that range from current (4G) and future (5G and beyond) cellular networks to personal and local area / WiFi networks to fixed wireless networks to wireless sensor networks to satellite networks to the Internet-of-Things to antenna modules and techniques for sensors, handsets, access points and base stations, etc. The large number of related vertical industries and sectors that benefit from these networks and processes are also targeted, such as: the automotive industry and other transportation sectors, including aviation; the energy sector (smart energy networks / smart grid); the security and safety sector, including surveillance, emergency and first responder systems; the manufacturing sector; the municipal sector (e.g. smart cities); the medical industry; the agricultural sector, the space sector, the government sector (e.g. spectrum regulation, environmental monitoring), etc.
