The Cisco 3G WWAN HWICs are the first enterprise-class 3G WWAN solutions. Suitable for both backup and primary applications, the Cisco 3G WWAN HWICs support the latest CDMA and GSM/UMTS standards (EVDO Rev A and HSDPA) and are backward compatible with the widely deployed networks (1xRTT, GPRS/EDGE). The Cisco 3G WWAN HWICs are tightly integrated with the services provided on the award-winning Cisco Integrated Services Routers, which deliver secure data, voice, video, and mobility services. The Cisco 3G WWAN HWICs are supported on the modular Cisco 1841 Integrated Services Router and Cisco 2800 Series and 3800 Series Integrated Services Routers. Enterprises are looking for ways to reduce costs, increase revenue, and improve business continuity. The Cisco 3G WWAN HWICs, when coupled with a service provider wireless data plan, provide a cost-effective, rapidly deployable, reliable, and secure backup solution for remote sites and branch offices. With data rates approaching T1 speeds, 3G Networks provide an alternative to wireline backup solutions such as ISDN, cable, and DSL. In the event of a network failure, the Cisco Integrated Services Router routes mission-critical data to the Cisco 3G WWAN HWIC for transmission across the wireless infrastructure. In addition, the router can distinguish different types of traffic and allow only mission-critical traffic to flow over the backup interface.
