Cisco MWR 1941-DC-A

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 new radio technologies such as UMTS/HSDPA and WiMAX voice and data networks; generate revenue from new cell-site IP-based services; and enable rapid deployment of next-generation mobile services.

Custom designed for the cell site, the CISCO1841-T1SEC/K9 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.

The primary Cisco IP Optimized RAN transport solutions, which may be deployed separately or in combination to suit the operator's specific network and business needs, include:

• Optimized RAN transport over IP: Maximizes GSM/GPRS/EDGE, UMTS/HSDPA, and 4G voice and data call density per T1/E1 over the RAN transport network to reduce backhaul transmission costs, which are typically the largest operational expenses in the network.

• Broadband and Ethernet RAN backhaul: Allows for a variety of backhaul transport media enabling higher-capacity and/or lower-cost alternative RAN transport for GSM, CDMA, and UMTS networks, such as DSL, WiMAX, and Metro Ethernet. Higher-speed broadband backhaul, such as DSL and Metro Ethernet, is ideally suited for transport of HSDPA, CDMA EV-DO, and WiMAX data traffic.

• Cell-site operations support networks: Enables telemetry to cell sites for remote operations and network element management of the ancillary cell-site equipment to reduce costly site visits and improve operational efficiency.

• Cell-site IP points of presence (POPs): Offer new revenue-generating IP services and applications at every cell site.
