Press Release Berlin, Germany – September 23, 2008 Nokia Siemens Networks launches mobile future-proof backhaul solution Nokia Siemens Networks has responded to the challenge of increasing data traffic with the launch of a microwave transport solution that offers operators a cost effective approach to upgrading backhaul networks that provides enough headroom to meet current and future demand. The Nokia Siemens Networks FlexiHybrid meets the need of operators currently confronting the challenge of finding a smooth migration path that enables them to move seamlessly from existing technology to packet-based networks. FlexiHybrid is a new indoor unit in Nokia Siemens Networks’ microwave portfolio offering operators a straightforward, yet future-proof step towards packet transport. The new platform supports both Fast Ethernet and Gigabit Ethernet, making it the ideal solution to cope with bursty the erratic and high volume traffic volumes created by internet applications. FlexiHybrid is a standards-based solution which ensures the interplay with today’s 3G and later 4G base stations. Support of TDM applications like conventional telephony is ensured - both E1 and STM-1 interfaces are available. When needed, the FlexiHybrid can be combined with fully packet-based Carrier Ethernet Transport solution paving the way to an all-packet-based network. “Operators need a solution that supports Super-PDH, hybrid, and fully packet based network archi-tectures,” said Vesa Tykkylainen, Head of Microwave Radio at Nokia Siemens Networks. “FlexiHy-brid is an effective solution, providing high flexibility and integration without added costs.” Flexihybrid helps operators to is easy and cost effective to install. It simply needs to be attached to the antenna and the base station. Furthermore it minimizes initial CAPEX for network build-out and enables low-cost logistics, maintenance and sparing of option modules. Existing PDH microwave radio links and SDH nodes can be upgraded to carry TDM and Ethernet in parallel, allowing traffic aggregation close to cell sites. “Today’s Ethernet technology will allow operators to supply bandwidth in a way that more closely fits to the customer needs,” continued Tykkylainen. “It will enable operators to make more money on their existing assets, save resources and capital expenditure while allow pricing models which are beneficial to both end-user and operator.” FlexibHybrid will first be displayed in a public interoperability test at the EANTC booth at Carrier Ethernet World Congress in Berlin.
