The Cisco 3G WWAN EHWICs are the first enterprise-class 3G WWAN solution. Suitable for both backup and primary applications, these cards support the latest 3G standards (Evolved High-Speed Packet Access [HSPA+] and Evolve-Data Optimized [EV-DO] Rev A) and are backward-compatible with High-Speed Packet Access (HSPA), Universal Mobile Telecommunications Service (UMTS), Enhanced Data Rates for Global Evolution (EDGE), General Packet Radio Service (GPRS), and EV-DO Rev 0/1xRTT. The Cisco 3G WWAN EHWICs Series has two variants:

• Global System for Mobile Communications (GSM) and UMTS models are based on 3GPP, and they support 3.7G HSPA+, 3.5G HSPA (Evolved High-Speed Packet Access (HSPA+/HSPA)), UMTS, EDGE, and GPRS.
• Code Division Multiple Access (CDMA) models are based on 3GPP2, and they support EV-DO Rev A/Rev 0 and 1xRTT.
