Cellular Backhaul Migration to Packet Transport

RAD enables a balanced migration to packet transport cellular backhaul, as well as substantial savings in operating and capital expenses, with an extensive portfolio featuring cell-site gateways (CSGs) and aggregation site gateways (ASGs). Connecting several base stations and node Bs at one end and aggregating BSC and RNC traffic at the other end, RAD’s ACE-3x00 and LA-130 simultaneously deliver 2G and 3G services across Ethernet, IP or MPLS backbones, using pseudowire technology. Introducing “any service any port” functionality, RAD’s CSGs and ASGs incorporate flexible port configuration to capitalize on carriers and operators’ existing assets, including legacy TDM/ATM infrastructure and widespread, low-cost DSL equipment. This includes traffic separation over hybrid PSN and TDM/ATM transport, to allow a gradual migration to all-IP radio access networks.

• Substantially boost bandwidth capacity to accommodate rollout of new cellular services and avoid the mobile broadband bottleneck

• Leverage packet transport’s scalability and flexibility for an efficient service upgrade

• Offset network expansion outlay and stagnant ARPU by curbing backhaul transport costs with cost-efficient PSN backbones, optimized transport efficiency, traffic grooming and overbooking, as well as 2G/3G colocation

• Provide robust clock synchronization per ITU-T G.823 and G.824 specifications, and support Synchronous Ethernet and IEEE 1588v2 distribution protocols

• Eliminate interworking and interoperability issues with a single platform for multi-generation traffic

• Support SLA-based quality-of-service (QoS) and traffic prioritization per service

• Ensure network is primed for fixed and mobile convergence (FMC) and new UMTS 3GPP, WiMAX standards
