TeliaSonera, the international mobile operator based in Scandinavia, has selected RAD’s 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. 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.
