    TeliaSonera deploys RAD’s cell site gateways across fibre-based all-IP mobile backhaul network

    -

    RAD Data Communications, a specialist in developing solutions for the transport of data, voice and signaling traffic in cellular and mobile applications, announced today that TeliaSonera, the international mobile operator based in Scandinavia, has selected its advanced cell site gateway to backhaul 2G and 3G mobile traffic over all-IP fibre infrastructure in Finland.

    RAD's ACE-3220 cell-site gateways will connect over the fibre network to Cisco's 7600 edge routers.

    "One of the keys in winning this project against a competitor with a strong local presence was our ability to quickly integrate with TeliaSonera's existing Cisco backbone network," noted Mati Epstein, Carrier Strategic Accounts Director at RAD, who led the company's sales team in the commercial negotiations with TeliaSonera.

    Currently, most mobile operators upgrading their backhaul networks to meet the demands of HSPA, and eventually LTE, are deploying one network for data and a separate one for time-sensitive legacy traffic such as voice. TeliaSonera will become one of the first operators of a unified all-IP mobile backhaul network. This breakthrough was made possible because RAD overcame the technological obstacles that until now have prevented the transport of legacy voice on a packet-switched cellular backhaul network without compromising Quality of Service (QoS). RAD's gateways employ pseudowires to allow legacy traffic to be carried over IP and, by providing accurate clock synchronisation, ensure that voice traffic is not victim to QoS issues generated by network delays.

    "This is a significant win for RAD in the mobile arena because it proves the business case for deploying an end-to-end pseudowire solution to simultaneously backhaul 2G and 3G traffic over fibre," stated Michael Howard, Principal Analyst and co-founder of Infonetics Research, "This represents a departure from the existing 'hybrid' or 'dual backhaul' model of HSDPA offload," Howard added, "and is a harbinger for the industry for tomorrow's backhaul architecture over a single packet network."
