Modern Operator’s Challenges Market trends Telephone operators are beginning to suffer from revenue attacks on their traditional voice services by cellular network operators and VoIP-bypass phone service providers. ILECs, CLECs and Mobile phone operators compete relentlessly with each other being forced to offer constantly new services and to achieve a cost effectiveness that can be transferred to their final products. “Differentiation” from the lot becomes the essence of business for modern telcos

Modern Operator’s Challenges Mobile/wireless traffic trends Source: Heavy Reading

Mobile Market & Technology Landscape Emergence of Mobile Broadband & Multimedia Services development New content & applications (Music, gaming, User-generated content) Mobile TV New enhancements to the air interfaces HSPA, HSDPA+, LTE, Mobile WiMax, CDMA EV-DO Fixed-Mobile substitution and/or convergence Global ARPU trends: Flat to negative for voice Cost Reduction Lower-cost IP/Ethernet technologies Ethernet service available from wireline carriers IP/Ethernet interfaces coming to the base station

Modern Operator’s Challenges Broadband & convergent backhaul Today Backhaul needs to support: Increased capacity Co-existing multiple technologies High peak to average traffic ratios Future migration to full Ethernet / IP BH represents ~20% of network CAPEX and ~30% of network OPEX Key to cost efficient deployment of new services Conventional TDM backhauling is inefficient Cost scales linearly with capacity TCO Revenue Need Backhaul that can offer more for less cost

Modernization of Access Network Infrastructure How to overcome Modernization of Access Network Infrastructure with F.T.T.x. Modern Highly Distributed Unified Solution

Generation of new revenue opportunities How to overcome Generation of new revenue opportunities New Services =more bandwidth = new architecture To achieve the high data rates required, it is necessary to deploy MSANs deep in the network to considerably shorten the distance to the subscriber, in a cost affordable way.

Phased Evolution Approach Backhaul Strategy: Phased Evolution Approach Every network has a different start point and each site may have different requirements Network Transformation aligned to Service Transformation and traffic increase Adapt to vendor specific HSPA transport capabilities HS on CBR VCs, UBR+ VCs, QoS mechanisms, etc. Separate ETH interface ? Evolution of backhaul networks depends on the capabilities and evolution of RAN and CN nodes Multiple generations of base stations Multiple network interfaces (TDM, ATM, IP/Ethernet) IP/MPLS to the cell site? Yes – but not necessarily to the cell site in every case

Microwave Backhaul Requirements Microwave is the dominant backhaul technology Microwave backhaul is required to carry both Ethernet & TDM traffic ~80% of 3G cell sites are collocated with 2G cell sites
