  • Enhanced 3GPP system for interworking with Fixed Broadband Access network
    IEEE Communications Magazine, 2013
    Co-Authors: Hyunsook Kim, Laeyoung Kim, Andreas Kunz
    Abstract:

    This article explains the 3GPP-BBF interworking architecture using WLAN Access or home (e)NodeB/femtocell Access in order to go toward single network for policy and QoS convergence. The interworking architectures and schemes ensure that the customers get the same service via any Access network. In addition, this article covers the mechanisms to support evolved packet core routed traffic and non-seamless WLAN offloaded traffic in the interworking architecture.

  • economics of Fixed Broadband Access network strategies
    IEEE Communications Magazine, 2003
    Co-Authors: T Monath, N Kristian, Philip Cadro, Dimitris Katsianis, Dimitris Varoutas
    Abstract:

    This article presents a comprehensive techno-economic evaluation of two upgrade strategy cases for Broadband IP services for residential and business customers, and illustrates their respective merits and pitfalls, allowing the definition of a reasonable investment policy. The work should enable establishment of guidelines for Broadband infrastructure upgrade strategies from the incumbent operator's view. Following the definition of appropriate service sets, and taking into account demand scenarios established within the project, this work has been focused on developing a techno-economic model, based on the TONIC tool. Tariff structures have been applied to compute the key economic indicators, net present value, internal rate of return, and payback period. This investment analysis was carried using the tool, which was developed by IST-TONIC. The results show that the choice of technology (Ethernet or ATM) has almost no effect on the cost level and profitability of the cases. For the suburban area, a fiber to the cabinet solution is too expensive due to heavy infrastructure investments; for dense urban and urban areas the FTTC solution is worth the investments. The FTTH/office deployment scenario is only profitable in dense urban areas (>5000 potential customers/km/sup 2/) and already highly risky in the urban area.

  • The fourth generation Broadband concept
    IEEE Communications Magazine, 2009
    Co-Authors: Per Ödling, Thomas Magesacher, Stefan Höst, Per Ola Börjesson, Miguel Berg, Enrique Areizaga
    Abstract:

    Fixed-Broadband Access technology is evolving from exclusively copper-based solutions to hybrid fiber-copper architectures. This article presents the expected next step in the evolution of Broadband systems, which we call the fourth-generation Broadband concept. It identifies a technical, infrastructural, and economical niche and describes how the fiber-Access network is extended and forked to feed a last and ultimate generation of DSL systems, shown to have gigabit potential. The underlying infrastructural concept is presented, economic aspects are described and discussed, and achievable data rates are calculated.
