The Cisco 3G WWAN HWICs are the first enterprise-class 3G WWAN solution. Suitable for both backup and primary applications, these cards support the latest 3G standards (High-Speed Packet Access [HSPA] and Evolve-Data Optimized [EVDO] Rev A) and are 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 HWICs Series has two variants:
- Global System for Mobile Communications (GSM) and UMTS models are based on 3GPP, and they support HSPA (High-Speed Uplink Packet Access (HSUPA) and High-Speed Downlink Packet Access (HSDPA)), UMTS, EDGE, and GPRS.
- Code Division Multiple Access (CDMA) models are based on 3GPP2, and they support EVDO Rev A/Rev 0 and 1xRTT.
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 and 1861 Integrated Services Routers and the Cisco 1900, 2800, 2900, 3800 and 3900 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 wire line backup solutions such as ISDN, cable, and DSL. 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.
With enhanced data rates and improved latency (below 100 milliseconds), WWAN services are an ideal way to supplement traditional wire line services. 3G WWAN data services offered today have average data rates well in excess of ISDN speeds, with theoretical limits in excess of 7 Mbps on the downlink and 5 Mbps on the uplink. You can use the 3G WWAN as a primary link for sites with lower bandwidth requirements and for mobile applications. You can also use the 3G WWAN data services as a cost-effective alternative in areas where broadband services are either not available or very expensive. Cisco is building on these performance milestones and adding support for wireless to our wide variety of WAN interface alternatives.
