Cisco MWR 2941-DC Mobile Wireless Router
The Cisco® MWR 2941-DC Mobile Wireless Router sets the standard for cell-site investment protection of
Radio Access Network (RAN) backhaul for multiple generations of radio and media technology. By using
the Cisco MWR 2941-DC, operators can simplify and converge their current RANs with a compact, highperformance, and modular cell-site access platform, reducing operating costs and enhancing profit
opportunities.
RAN cell sites are places of transformation between mobile radio and mobile transport networks. Cost-effective RAN
backhaul requires the ability to simultaneously aggregrate the transport of traffic from both legacy and newgeneration radios for specific and multiple transport options available at the cell site. The Cisco MWR 2941-DC is
designed to optimize this radio-to-transport transformation and provide scalable interfaces for existing radios and
transport networks as well as the new generation of 4G radios, microwave, and IP RAN transport networks.
Product Overview
The Cisco MWR 2941-DC Mobile Wireless Router (Figure 1) is a cell-site gateway specifically designed to clock,
aggregate, and backhaul mixed-generation RAN traffic. The Cisco MWR 2941-DC prioritizes and processes cell-site
voice, data, and signaling traffic as part of the Cisco Unified RAN Backhaul solution for reliable transport across any
available backhaul networks, including E1/T1, ATM, Carrier Ethernet, microwave, WiMAX, and satellite networks.
Custom designed for the cell site, the Cisco MWR 2941-DC features a small form factor, superior clocking, extended
operating temperatures, and cell-site DC input voltages. It includes a high-performance host processor joined with a
powerful dataplane network processing engine, a line-rate Level 2 switch, precise clocking and synchronization, and
comprehensive Cisco IOS® Software customized for RAN backhaul applications.

The primary benefits of Cisco Unified RAN Backhaul solutions with cell-site gateway include:
●
Line-rate cell-site traffic segmentation: Allows you to segment traffic for backhauling 2G traffic and 3G
voice over time-division multiplexing (TDM) infrastructure (T1/E1), while simultaneously using any available
high-speed broadband networks (for example, Carrier Ethernet) to backhaul High-Speed Packet Access
(HSPA) and Long-Term Evolution (LTE), Code Division Multiple Access (CDMA), Evolution-Data Optimized
(EVDO), and WiMAX data traffic
●
Cell-site aggregation and expansion: Aggregates multiple base stations through multiple TDM, Ethernet,
and IP interfaces
●
Pseudowire Emulation Edge to Edge (PWE3): Supports Global System for Mobile Communications (GSM),
CDMA, and Universal Mobile Telecommunications System (UMTS) traffic for high-capacity, low-cost RAN
transport
●
Quality assurance: Lets you apply quality of service (QoS) at the cell site for improved service-level
assurance, even over noisy microwave links

●
Metro Ethernet support: Allows you to manage and operate in both a PWE3 and Carrier Ethernet
environment simultaneously by supporting line-rate Layer 2 Ethernet Operations, Administration, and
Maintenance (EOAM, including Connectivity Fault Management [CFM], Ethernet Local Management Interface
[E-LMI], and Ethernet in the First Mile [EFM]), Resilient Ethernet Protocol (REP), and QinQ
●
Cell-site operations support: Facilitates 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): Allows you to offer new revenue-generating IP services and
applications at every cell site

Software Overview
The software for the Cisco MWR 2941-DC is customized for IP RAN transport and includes several Cisco IOS
Software features specifically developed for such applications. These features include Adaptive Clock
Recovery(ACR), IEEE 1588-2008, ITU-T Synchronous Ethernet (SynchE), and IETF ATM, TDM, and Ethernet
Pseudowire Emulation Edge to Edge (PWE3). Another important feature is Cisco ATM permanent virtual circuit
(PVC) routing, which provides the ability to route different types of 3G traffic over different types of backhaul media,
while providing load-balancing and backup paths.
The software available for the Cisco MWR 2941-DC supports Cisco IOS Software running on the host processor and
microcode running on the network processor to provide hardware acceleration to increase performance of PWE3
protocols, Multilink Point-to-Point Protocol (MLPPP), Multiprotocol Label Switching (MPLS), and ATM network
services such as ATM cell segmentation and reassembly (SAR), ATM Adaption Layer 0 (AAL0) for AAL2 voice and
data, AAL5, and Inverse Multiplexing over ATM (IMA) v1.0 and v1.1.
