Concept of CONFES Project

Modern telecommunications are characterized by continuous evolution to new generation wired-wireless networks/systems. Support of higher data rates enabled the provision of new, innovative broadband (IP-based) services (e.g. mobile-TV, HDTV, IPTV, video surveillance, VoD, interactive gaming, broadband internet), which led to a significant telecommunications’ traffic increase, while at the same time, it boosted user requirements for broadband access everywhere, high quality of service, portability/mobility and fixed mobile convergence.
The biggest challenge for the telecommunications industry is to satisfy user requirements and optimally utilize network infrastructure to achieve sustainable solutions for industry (network/service providers, telecom equipment/terminals/chipsets vendors) and also to achieve affordable offers for the users.
The backhaul network is one of the most critical parameters affecting the quality of service, flexibility in introduction of new services/applications, and the required investments.
CONFES project aims to develop an integrated wireless-wired transmission network infrastructure of ultra-high capacity, serving both next generation mobile networks and fixed metropolitan ones, based on optical technologies, namely passive optical networks (PON), considering the advantages of this technology in terms of flexibility in managing traffic according to the time varying bandwidth requirements, operating costs and the ability for future network upgrades/expansions (future proof solution).
At the same time, CONFES architecture will meet the requirements for:

  • Flat design, dynamic reconfiguration and optimized processes for end-to-end resource allocation (for both wireless and optical parts of the network), traffic sharing and scheduling, technology convergence to reduce operational costs (OPEX) and investment costs (CAPEX).

  • Automatic adaptation to the frequent traffic fluctuations that characterize a typical next generation wireless network (LTE, 4G), where frequent handovers are observed (due to multiple small cells) with high spectral requirements.

  • Suitable mechanisms for traffic management, routing, measurements and performance analysis through an integrated management platform.

  • Flexible service provisioning and guaranteed quality of service (QoS).

  • Seamless service provisioning and error recovery, in case of network failures.
