Des de la seva formació l'any 1988, tasques de consultoria, formació i investigació en diferents àmbits de les comunicacions mòbils, xarxes sense fils, protocols de comunicació i adaptació de continguts. Part d'aquestes tasques s'han realitzat per a organismes i empreses líders del sector: Telefónica, Vodafone, Retevisión, Alcatel, Sener, Doxa, Unitek, Fecsa, Institut Català de Tecnologia, Associació Catalana d'Enginyers de Telecomunicació, Centre de Telecomunicació de la Generalitat de Catalunya, etc. Les activitats d'investigació del grup WNG s'emmarquen en projectes d'investigació amb subvenció pública, principalment del Ministerio de Educación y Ciencia i de la Comissió Europea. Diversos membres del WNG participen en l'avaluació de propostes i revisions de projectes en execució dels esmentats organismes.

    Stringent demands for a continuous evolution of cellular networks push today academic and industrial researchers to re-think backhaul solutions for 5G. In one hand, wireless backhaul solutions are cost effective and easy ...
  • Channel model of molecular communication via diffusion in a vessel-like environment Considering a Partially Covering Receiver 

    Turan, Meriç; Kuran, Mehmet Sükrü; Yilmaz, Hüseyin Birkan; Seyfettin Demirkol, Ilker; Tugcu, Tuna (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    By considering potential health problems that a fully covering receiver may cause in vessel-like environments, the implementation of a partially covering receiver is needed. To this end, distribution of hitting location ...
  • Intertwined localization and error-resilient geographic routing for mobile wireless sensor networks
