EHWIC-3G-EVDO-B

The Cisco? 3G WWAN EHWICs are a new 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 [EV-DO] 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 EV-DO Rev A and Rev 0 and 1xRTT. The Cisco 3G WWAN EHWICs 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 EV-DO Rev A and Rev 0 and 1xRTT.
• The Cisco 3G WWAN EHWICs are tightly integrated with the services provided on the award-winning Cisco ISR G2 routers, which deliver highly secure data, voice, video, and mobility services. The Cisco 3G WWAN EHWICs are supported on the modular Cisco 1900, 2900 and 3900 Series Integrated Services Routers (ISRs) part of the Cisco ISR G2 portfolio.
• Enterprises are looking for ways to reduce costs, increase revenue, and improve business continuity. The Cisco 3G WWAN EHWICs, 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 ISR routes mission-critical data to the Cisco 3G WWAN EHWIC 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. The 3G wireless WAN EHWICs are available in multiple part numbers. The CDMA part number is EHWIC-3G-EVDO-x1 (where x reflects the wireless carrier) and EHWIC-3G-HSPA-U. Figure 1 shows the cards.
