REWIND focuses on one of the most important concepts in wireless network infrastructure that will revolutionize the level of wireless broadband services in terms of network capacity and coverage while reducing operational expenditures. This concept, the Relay based Wireless Network, will create through proliferation of low-cost, easy to install Relay Stations providing the necessary capacity and coverage to support new wireless applications with similar QoS currently available only through wired broadband service (e.g. DSL). At the same time the Relay Station receiving its capacity from its own access network through an efficient backhauling mechanism will maximize utilization of the infrastructure capacity and spectrum reuse, without the need for additional CAPEX or OPEX associated with dedicated backhaul. As REWIND is looking to develop state-of-the-art technology, products and network that will have effect on the network of the future in the coming years, it will be based on WiMAX, the most advanced, yet available and standardized broadband wireless technology. REWIND has two main objectives:•Creation of a complete WiMAX relay based beta network including:-Network operator requirements and business case analysis-Network architecture and system specification-Development of relay technology and algorithms over a System on Chip (SoC) platform-Development of WiMAX relay beta prototype-System integration and interoperability of the developed relay product with standard WiMAX base station and subscriber station equipment-Lab and field performance testing of the integrated beta prototype relay systemTo provide support and directions to WiMAX relay standardization by providing inputs through participation and contributions on the aspects developed in the creation of the beta network.The REWIND partners form a balanced and complete group including all the ingredients required for the creation of the beta prototype network.
