Joerg Widmer, ponente plenario en AD-HOC NOW 2014

09 Julio 2014

Joerg Widmer, Research Professor en IMDEA Networks, ha sido uno de los tres ponentes plenarios o keynotes seleccionados para participar en el decimotercer congreso internacional sobre redes inalámbricas y ad-hoc ADHOC-NOW 2014.  El evento, que se enfoca a la realización de ponencias y discusiones sobre investigación teórica y experimental en curso, se celebró en Benidorm, España, del 22 al 27 de junio de 2014.

Resumen de la ponencia “Spectrum for the Masses: Networking in the Millimeter Wave Band”

State-of-the-art wireless communication already operates close to Shannon capacity and one of the most promising options to further increase data rates is to increase the communication bandwidth. Very high bandwidth channels are only available in the extremely high frequency part of the radio spectrum, the millimeter wave band (mm-wave). Upcoming communication technologies, such as IEEE 802.11ad, are already starting to exploit this part of the radio spectrum. However, communication at such high frequencies suffers from high attenuation and signal absorption, often restricting communication to line-of-sight (LOS) scenarios and requiring the use of highly directional antennas. This in turn requires a radical rethinking of wireless network design. On the one hand side, such channels experience little interference, allowing for a high degree of spatial reuse and potentially simpler MAC and interference management mechanisms. On the other hand, such an environment is extremely dynamic and channels may appear and disappear over very short time intervals, in particular for mobile devices. This talk will highlight some of the challenges of and possible approaches for networking in the mm-wave band.
