The Cisco 3G WWAN HWIC is the enterprise-class 3G WWAN solution. Suitable for both backup and primary applications, this card supports the 3G standards and is backward-compatible with Universal Mobile Telecommunications Service (UMTS), Enhanced Data Rates for Global Evolution (EDGE), General Packet Radio Service (GPRS), and EVDO Rev 0/1xRTT. The Cisco 3G WWAN HWIC is tightly integrated with the services provided on the Cisco integrated services routers, which deliver secure data, voice, video, and mobility services.
Enterprises are looking for ways to reduce costs, increase revenue, and improve business continuity. The Cisco 3G WWAN HWIC, when coupled with a service provider wireless data plan, provides a cost-effective, rapidly deployable, reliable, and secure backup solution for remote sites and branch offices. If a network fails, 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.

Integrated 3G WWAN broadband
With the 3G WWAN modem integrated into the router, you gain the benefit of simplified installation and management. In addition, the Cisco 3G WWAN HWIC is tightly integrated with Cisco integrated services routers.
-
Short installation time
Businesses sometimes wait for weeks or months to get data circuits installed at new locations. For temporary or seasonal sites, wireless data services allow instant connectivity anywhere there is cellular coverage, and rapid deployment allows you to quickly set up networks with WAN connectivity.
-
Network resiliency through WAN diversity
WAN connectivity is crucial to the functioning of your business, and any downtime means a loss of productivity and lost opportunity. Staying connected and operational during a network outage can be vital. A wireless connection for backup to a remote site provides protection against line outages and an additional level of redundancy because the 3G WWAN infrastructure is often served by separate facilities, providing redundancy for the entire local loop.
-
Reduced cost
The emerging 3G WWAN cellular data service plans are competitively priced with existing wireline services. 3G WWAN solutions also allow you to consolidate your service providers across large geographical areas instead of having service contracts with multiple service providers.
-
High performance
With increasing data usage and the proliferation of web-based applications at remote sites, there is an increasing need for high-speed data connections to run mission-critical applications at these sites. 3G WWAN services promise low-latency links, allowing you to send and receive more mission-critical data across the WAN in backup scenarios.
