Cisco® announces the availability of the Cisco Broadband Wireless Gateway (BWG) for the Cisco 7600 Series Routers and the Cisco 7301 Router. The Cisco Broadband Wireless Gateway delivers best-in-class functionality, service control, and performance in a highly scalable, fault-tolerant package for the emerging WiMAX-based broadband wireless solution. Available for order now, the Cisco Broadband Wireless Gateway uses the high-capacity parallel processing of the Cisco Service Application Module for IP (SAMI) to enable the delivery of broadband wireless at access speeds previously only available with wireline access networks.
As the edge aggregation device in the IP end-to-end WiMAX network, the Cisco Broadband Wireless Gateway is an essential network element for service providers focused on implementing an open IP architecture in a multivendor WiMAX environment. The Cisco Broadband Wireless Gateway builds on proven and market-leading Cisco IP technology to aggregate subscriber connections serviced by WiMAX base stations. It also provides authentication and mobility management, Mobile IP foreign agent services, key distribution, and quality-of-service (QoS) functionality.
WiMAX End-to-End Reference Model
Figure 1 shows the WiMAX end-to-end Reference Model as defined by the WiMAX Forum's Network Working Group. It consists of the following logical entities: Mobile Subscriber Station (MSS), Access Service Network (ASN), and Core Service Network (CSN). Further ASN decomposition is shown in Figure 2. The Network Reference Model (NRM) is a logical representation of the network architecture. The NRM identifies functional entities, and reference points over which interoperability may be achieved between functional entities.

Cisco Service Exchange Framework
The Cisco Broadband Wireless Gateway is part of the Cisco Service Exchange Framework (SEF), an open platform that can readily interface to all the control elements in a mobile network, including multiple radio access networks (RANs), back-end billing systems, and content filtering and compression solutions. With more than 100 mobile operators worldwide having deployed Cisco SEF, Cisco has already demonstrated its commitment to the compatibility of its SEF platform with major RANs; authentication, authorization, and accounting (AAA); content billing; content filtering; compression solutions; and gateways, relieving service providers of the need to dedicate resources to ensure a smooth deployment. Cisco continuously applies customer feedback to add valuable new features, maintaining the innovation and cost-effectiveness of its SEF platform.
Cisco's strong partnerships with SEF billing and mediation, filtering, and now WiMAX radio vendors allows it to provide end-to-end SEF solutions. With SEF, the Cisco Broadband Wireless Gateway delivers the service and subscriber awareness, along with performance and scaling, which are essential to the high-capacity aggregation WiMAX environment. In addition, the Cisco Broadband Wireless Gateway provides implementation flexibility for cost-effective delivery of broadband wireless services - thereby enabling increased customer loyalty and new revenue streams.
The cornerstone of the Cisco offering is the Mobile SEF architecture (Figure 3). The Cisco Mobile SEF supports service access control, deep packet inspection, Mobile IP, security, and packet gateways for each of the major radio technologies. Packet gateway options include the Cisco Packet Data Serving Node (PDSN) for CDMA, Cisco Gateway GPRS Support Node (GGSN) for GSM/UMTS, and Cisco Broadband Wireless Gateway for WiMAX deployments. The home agent is used as an anchor point to provide easy mobility across access technologies.

Cisco Broadband Wireless Gateway Features and Benefits
The Cisco Broadband Wireless Gateway provides subscriber and base station aggregation to facilitate the delivery of IP end-to-end high-speed broadband services to mobile subscribers using WiMAX (IEEE 802.16-2005). The Cisco Broadband Wireless Gateway provides WiMAX standards-based R3 protocol (Cisco Broadband Wireless Gateway/home agent) and R6 protocol (Base Station/Cisco Broadband Wireless Gateway), which are essential to implementing an open IP architecture in a multivendor WiMAX environment.
In addition to aggregating subscriber connections serviced by WiMAX base stations, the Cisco Broadband Wireless Gateway provides authentication and mobility management, Mobile IP foreign agent services, key distribution, and QoS functionality. The Cisco Broadband Wireless Gateway enables subscriber roaming and VPN services to deliver the flexible service environment needed by enterprises and service providers.
