The Cisco RAN Optimization solution enables mobile operators to aggregate and transparently transport mixed-generation (2G, 3G, 4G) digital voice and data calls over the existing RAN backhaul network using IP, as well as optimize over the backhaul network to reduce the amount of required backhaul bandwidth by as much as 50 percent and often much more. As a result, the solution reduces existing backhaul transmission costs and enables more cost-efficient deployment of new RAN technologies. The backhaul network is typically the largest operational expense in the mobile operator's network.
The Cisco T1/E1 RAN VWIC terminates GSM Abis T1/E1s, UMTS Iub T1/E1s, and backhaul T1/E1s, and processes the GSM/GPRS/EDGE and UMTS/HSDPA traffic for IP-based optimization over the RAN backhaul transport network. As RAN traffic loads change, the Cisco T1/E1 RAN VWIC used for a GSM Abis T1/E1 can be reused for a UMTS Iub T1/E1. Or as backhaul networks move to high-speed alternative backhaul technologies such as those used for broadband access, a Cisco T1/E1 RAN VWIC used for a backhaul T1/E1 can be reused for a UMTS Iub T1/E1 (Figure 2).
