The Cisco MWR 1941-DC-A Mobile Wireless Edge Router is a cell-site access platform specifically designed to optimize, aggregate, and transport mixed-generation Radio Access Network (RAN) traffic. It allows mobile wireless operators to significantly lower existing operating expenses (OpEx); cost-efficiently deploy radio technologies such as UMTS/HSDPA and WiMAX voice and data networks; generate revenue from cell-site IP-based services; and enable rapid deployment of next-generation mobile services.Custom designed for the cell site, the Cisco MWR 1941-DC-A features a small form factor, extended operating temperature, and cell-site DC input voltages. It comprises a high-performance architecture, driven by a powerful MIPS RISC processor coupled with an optional ATM network processing engine, combined with application-specific Cisco IOS Software-based operating software tailored for IP RAN transport. The Cisco MWR 1941-DC-A has a modular design, providing flexibility and a variety of connectivity options at the cell site through support for select modules from the Cisco 2800 and 3800 Series Integrated Services Router platforms.The Cisco MWR 1941-DC-A enables a variety of RAN solutions by extending IP connectivity to GSM/GPRS/EDGE base transceiver stations (BTSs), UMTS/HSDPA Node Bs, CDMA/CDMA-2000/EV-DO BTSs, and other ancillary cell-site equipment. It transparently and efficiently transports cell-site voice, data, and signaling traffic over IP using traditional T1/E1 circuits, including leased line, microwave, and satellite, as well as alternative backhaul networks, including DSL, EFM, Metro Ethernet, and WiMAX. It also supports standards-based Internet Engineering Task Force (IETF) Internet protocols over the RAN transport network, including those standardized at the Third-Generation Partnership Project (3GPP) for IP RAN transport.
