Meet a Key Backhaul Challenge –

The Rapid Growth of Multimedia Traffic

The mobile market is changing, and to remain competitive, mobile service providers must deliver new profitable services and reduce their backhaul costs. Mobile user demand continues to move beyond basic data services like instant messaging and e-mail to more delay sensitive applications like media streaming and real-time multimedia. In response, broadband wireless technologies including high-speed packet access (HSxPA) and evolution

data optimized (EV-DO) are evolving to enable higher transmission speeds and packet interfaces. Backhaul networks must evolve to meet these new bandwidth demands at acceptable cost points.

IP transport can help mobile providers transform their networks — to better manage the increasing traffic demands of broadband services. To satisfy the need for new packet backhaul solutions,

Alcatel-Lucent offers a revolutionary way of transporting packets natively. With this new approach, the Alcatel- Lucent 9500 MPR product can assure the quality of service required for each traffic type, dramatically reduce OPEX and improve the connectivity of Ethernet and legacy E1 base stations. As a result, your network can absorb rapid growth in multimedia traffic easily and efficiently, with a smooth migration from TDM to IP.

Figure 1. TDM Transport compared to Packet Aggregation. There is a clear gain in scarce radio resources when transporting packet traffic natively. Packet solutions can absorb TDM traffic efficiently while TDM solutions cannot handle packet traffic cost-efficiently.
