Le recordamos que en el Informe mensual puede ampliar esta información.

Boletín 31. Septiembre de 2006.

Contenidos:



  • Geotagging. El servicio permite adscribir fotos almacenadas a lugares sobre un mapa. Está integrado con Yahoo! Maps, y se accede a través del Organizer, permitiendo navegar en visión mapa, satélite o mixta, y situar las fotos individualmente o en grupos.(sigue)


  • Todo X Artista. Servicio para acceder a los contenidos de los artistas: biografías, tonos reales, las últimas noticias, futuros conciertos, fotos, ...(sigue)


  • Yahoo Go. Correo, Yahoo! Search, Fotos, Agenda y Calendario, Noticias-Deportes-Finanzas son los servicios que los usuarios pueden tener disponibles en su móvil(sigue)


  • Friend FindA. El servicio lanzado por la operadora australiana permite a los amigos localizarse rápida y fácilmente, utilizando sus teléfonos móviles. La privacidad está asegurada mediante el mutuo consentimiento de utilización, y con la opción de los usuarios de hacerse "invisibles" cuando lo deseen. (sigue)


  • party-Strands. El servicio, implantado ya en una decena de bares españoles, permite a la gente influir sobre la música que se escucha en los bares a través de su teléfono móvil.(sigue)

  • Mobile devices including RFID tag readers. A wireless access point in an object location system is provided that includes a tag filtering agent 128 operable to (a) receive tag information from a mobile communication device 104, (b) compare the received tag information with a set of a plurality of tag information to determine whether to report... (sigue)


  • Congestion notification in 3G radio access. A method, apparatus and system of network congestion notification is disclosed. A source node sends a destination node a data packet. Upon receipt of the data packet if network congestion is detected, the destination node introduces a congestion indication into a data packet. The data packet, including... (sigue)

  • Wireless location technologies for CDMA cellular radio networks. Wireless position location has received considerable attention in CDMA cellular radio networks over the past few years. The process of calculating the location estimate can be views as consisting of two parts. The first part provides estimates of location parameters and the second part is the algorithm... (sigue)


  • The competition and cooperation of WiMAX, WLAN AND 3G. WiMAX has been the hottest topic since the year 2004. Controversy on advantages and disadvantages of WiMAX, WLAN and 3G along with the emergency of WiMAX upsets masses of mobile equipment suppliers as well as telecommunication operators. IEEE standard 802.16d was released in July 2004 and 802.16e, supporting... (sigue)


  • WiMAX radio access networks-status and evolution perspectives. Radio access networks based on WiMAX technology are currently soliciting considerable attraction. Based on an OFDM type air interface and realizing fully IP based radio access network solutions WiMAX technology is considered playing an important role in emerging deployments for high data rate radio... (sigue)


  • From 3G mobile TV to unlimited mobile TV. Mobile TV is on track to become a major mass market. It has the potential to boost operators' revenues, and is currently driving 3G usage as demonstrated by the TV service uptake of leading mobile operators. Today, more than half of the 3G networks worldwide are already mobile TV enabled. The mobile... (sigue)


  • Overview on UMTS HSDPA and enhanced uplink (HSUPA). HSDPA, an extension of UMTS, provides data rates of theoretically up to 14.4 Mbit/s. Realistically, data rates for each user of around 2 Mbit/s are expected. In comparison to UMTS (Rel. '99) the scheduling is moved from the radio network controller (RNC) to the node B, adaptive modulation and coding... (sigue)


  • Adaptive UMTS handover control algorithm in third generation wireless systems. Handover control algorithms have been designed initially to ensure a seamless migration in cellular systems. With a better understanding of wireless systems and communication channels, instead of focusing only on the seamless migration process in wireless systems, the handover control designs have been... (sigue)


  • A new architecture for wireline access to the 3G IP multimedia subsystem. In this paper we propose a novel architecture for converged multimedia SIP (session initiation protocol) services in wireline and 3G networks. The work on the future evolution of 3G systems is taking momentum with ongoing research on access to the IMS (IP Multimedia Subsystem) from any broadband access... (sigue)

  • Implementing VoIP Service Over Wireless Network. Voice over Internet Protocol (VoIP) technology facilitates packet based IP networks to carry digitized voice. With VoIP, competitive carriers and service providers can offer telephony (voice and fax) services together with traditional data services over the same IP infrastructure, and by doing so, increase... (sigue)


  • Towards an RFID policy for Europe. The main objective of the workshops was to bring together relevant stakeholders, raising and discussing concerns envisaged by these stakeholders in the field of RFID and collaboratively chart out new ways to address the related challenges and opportunities. As this document contains the proceedings... (sigue)


  • WiMAX - Copper in the air. Revisión de la tecnología WiMAX: características radio, consideraciones de espectro, servicios y aplicaciones, terminales, oportunidades para los operadores. (sigue)


  • WiMAX System Performance Studies. There are several ways of quantifying the performance of a broadband system. This paper will address two pressing issues of WiMAX system design which are interference and capacity analysis. This paper considers the factors affecting these two performance measures and discusses how to properly take... (sigue)
