The Cisco Third-Generation Wireless WAN High-Speed WAN Interface Cards are the first enterprise-class 3G WWAN solution. Suitable for both backup & primary applications, the Cisco 3G WWAN HWICs support the latest CDMA & GSM/UMTS standards (EVDO Rev A & HSDPA) & are backward compatible with the widely deployed networks (1x RTT, 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, & mobility services. The Cisco 3G WWAN HWICs are supported on the modular Cisco 1841 Integrated Services Router & Cisco 2800 Series & 3800 Series Integrated Services Routers. Enterprises are looking for ways to reduce costs, increase revenue, & improve business continuity. The Cisco 3G WWAN HWICs, when coupled with a service provider wireless data plan, provide a cost-effective, rapidly deployable, reliable, & secure backup solution for remote sites & branch offices. With data rates approaching T1 speeds, 3G Networks provide an alternative to wireline backup solutions such as ISDN, cable, & 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 & allow only mission-critical traffic to flow over the backup interface.
