Sundeep RANGAN


Professeur Biographie : Sundeep Rangan received the B.A.Sc. at the University of Waterloo, Canada and the M.Sc. and Ph.D. at the University of California, Berkeley, all in Electrical Engineering. He has held postdoctoral appointments at the University of Michigan, Ann Arbor and Bell Labs. In 2000, he co-founded (with four others) Flarion Technologies, a spin off of Bell Labs, that developed Flash OFDM, one of the first cellular OFDM data systems and precursor to 4G systems including LTE and WiMAX. In 2006, Flarion was acquired by Qualcomm Technologies where Dr. Rangan was a Director of Engineering involved in OFDM infrastructure products. He joined the ECE department at NYU Tandon (formerly NYU Polytechnic) in 2010. He is a Fellow of the IEEE and Director of NYU Wireless, an academic-industry research center researching next-generation wireless systems. Research topic: Texte à mThe spectrum landscape for wide-area wireless systems is rapidly changing. Fifth generation (5G) cellular systems opened up large swaths of spectrum in the millimeter wave (mmWave) bands that offered massive peak data rates. But obtaining reasonable coverage at practical cell densities has been a challenge. Recent interest has now focused on the so-called upper mid-band from 7 to 24 GHz that hopes to offer a balance of coverage and spectrum. But, cellular services in these bands must compete with incumbent services, notably rapidly expanding satellite mega constellations and vital existing defense systems. Available spectrum is thus emerging as a range of disparate bands with intermittent availability and coverage to be shared among a plurality of competing services. These developments will force a new area of agile spectrum sharing systems where multiple services support a wide range of bands where the frequency of operation! changes dynamically. In this talk, we will review recent results on developing such spectrally agile systems including (1) capacity analyses with adaptive frequency hopping; (2) algorithms for satellite and terrestrial co-existence; (3) new localization systems and their use in robotic navigation, and (4) novel experimental platforms. Joint work with Marco Mezzavilla (Politecnico di Milano), Hamed Rahmani (NYU), Aditya Dhananjay, and Mike Zappe (Pi-Radio).odifier dans l’interface d’édition: champ 'description' de la page sujet.
