Cisco MWR 2941 Router Overview
The Cisco MWR 2941 Mobile Wireless Router is cell-site access platforms specifically designed to
aggregate and transport mixed-generation radio access network (RAN) traffic. The router is used at the
cell site edge as a part of a 2G, 3G, or 4G radio access network (RAN). The Cisco MWR 2941 includes
the following models:
• Cisco MWR 2941-DC
• Cisco MWR 2941-DC-A
The Cisco MWR 2941 router helps enable a variety of RAN solutions by extending IP connectivity to
devices using Global System for Mobile Communications (GSM), General Packet Radio Service
(GPRS), Node Bs using HSPA or LTE, base transceiver stations (BTSs) using Enhanced Data Rates for
GSM Evolution (EDGE), Code Division Multiple Access (CDMA), CDMA-2000, EVDO, or WiMAX,
and other 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 Carrier Ethernet, DSL, Ethernet in the First Mile
(EFM), 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.
Custom designed for the cell site, the Cisco MWR 2941 features a small form factor, extended operating
temperature, and cell-site DC input voltages.
Note The Cisco MWR 2941-DC and 2941-DC-A support the same features except for commands related to
the 1PPS, 10Mhz, 2.048Mhz, and 1.544Mhz timing ports that are included on the 2941-DC-A. For more
information, see the Release Notes for Cisco MWR 2941-DC Mobile Wireless Edge Router.
Introduction
A typical RAN is composed of thousands of base transceiver stations (BTSs)/Node Bs, hundreds of base
station controllers/radio network controllers (BSCs/RNCs), and several mobile switching centers
(MSCs). The BTS/Node Bs and BSC/RNC are often separated by large geographic distances, with the
BTSs/Node Bs located in cell sites uniformly distributed throughout a region, and the BSCs, RNCs, and
MSCs located at suitably chosen Central Offices (CO) or mobile telephone switching offices (MTSO).
