While radio networks transition to new packet technologies, existing PDH infrastructure continues to play a significant role in cellular backhaul. For example, most of today’s microwave backhaul connections remain TDM-based. Without appropriate equipment that can offer cross-generation support, cellular operators and transport providers could face rollout delays for mobile broadband services, putting a strain on their profitability.
RAD’s RICi demarcation devices enable operators to utilize widely available TDM infrastructure for next generation mobile connectivity without heavy investments in new backbone connections. Figure 1 illustrates how these devices transport HSDPA cellular Ethernet traffic from an IP NodeB to the RNC (radio network controller) over TDM radio links in a point-to-point deployment. Employing standard Ethernet over NG-PDH protocols, the RICi demarcation devices offer bundled access rates of up to 32 Mbps and optimize line utilization and throughput. By providing a smooth migration path to IP RANs (radio access networks), these devices support substantial increase in data traffic volumes for HSDPA services while protecting operator margins.
