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.

    Conference report
    Restricted access - publisher's policy
    The explosive growth in the usage of IEEE 802.11 network has resulted in dense deployments in diverse environments. Most recently, the IEEE working group has triggered the IEEE 802.11ax project, which aims to amend the ...
  • CoCoA+: an advanced congestion control mechanism for CoAP 

    Betzler, August; Gómez Montenegro, Carlos; Seyfettin Demirkol, Ilker; Paradells Aspas, Josep (Elsevier, 2015-10-01)
    Article
    Open Access
    The Constrained Application Protocol (CoAP) has been designed by the Internet Engineering Task Force (IETF) for Internet of Things (IoT) devices. Due to the limited radio channel capacities and hardware resources of such ...
  • Modelling surfaces from planar irregular meshes 

    Cotrina Navau, Josep; Pla García, Núria (1998-06)
    External research report
    Open Access
    We present a method for constructing surfaces from irregular control meshes that can be embedded in the plane. This method results from a generalization of B-Splines using the known technology of manifolds. The resulting ...
  • REACH2-Mote: a range-extending passive wake-up wireless sensor node 

    Chen, Li; Warner, Jeremy; Yung Pak, Lam; Zhou, Dawei; Heinzelman, Wendi; Seyfettin Demirkol, Ilker; Muncuk, Ufuk; Chowdhury, Kaushik Roy; Basagni, Stefano (2015-11-01)
    Article
    Open Access
    A wireless sensor network that employs passive radio wake-up of the sensor nodes can reduce the energy cost for unnecessary idle listening and communication overhead, extending the network lifetime. A passive wake-up radio ...
  • Performance evaluation and comparative analysis of SubCarrier Modulation Wake-up radio systems for energy-efficient wireless sensor networks 

    Oller Bosch, Joaquim; Seyfettin Demirkol, Ilker; Casademont Serra, Jordi; Paradells Aspas, Josep; Gamm, Gerd Ulrich; Reindl, Leonhard Michael (2013-12-19)
