Fourth-Generation Long-Term Evolution (4G LTE) is being used to provide both primary connectivity and network resiliency for business continuity. With greater agility and speed to deployment than wired solutions, 4G LTE reduces network cost and complexity while maintaining ROI. Practical applications of 4G LTE for distributed enterprises include parallel networks, primary connection, failover, in-vehicle, network convergence, and wireless WAN diversity. The Cisco 4G LTE EHWICs for Integrated Services Routers Generation 2 (ISR G2) are the industry leaders in bringing enterprise-grade wire-line-like functionality such as quality of service (QoS) for cellular, Multi-VRF for cellular, and unified communications solutions over LTE.
The Cisco 4G LTE EHWICs are the first enterprise-class multimode 4G LTE wireless WAN (WWAN) solution. With 4G LTE, WWAN is a primary WAN link solution. Businesses can now run applications such as interactive video and telepresence on a primary 4G LTE WWAN link, which is 10 to 15 times faster and has 5 times lower latency than 3G links. These cards support the latest Third-Generation Partnership Project (3GPP) Release 8 Category 4 LTE standards. Cisco multimode 4G LTE WWAN EHWICs provide persistent, reliable LTE connectivity with fallback and transparent handoff to earlier technologies. The cards provide bandwidth to support high-definition (HD) and peer-to-peer (P2P) video calls, providing customers with an excellent mobile broadband experience. The Cisco 4G LTE WWAN EHWICs are tightly integrated with the services provided on the award-winning Cisco ISR G2 devices, which deliver secure data, voice, video, and mobility services. The EHWICs are supported on the modular Cisco 1900, 2900, and 3900 Series ISR G2 devices.
Enterprises are looking for ways to reduce deployment time, enable comprehensive media services, increase revenue, and improve business continuity. The Cisco 4G LTE WWAN EHWICs, when coupled with a service provider's wireless data plan, provide a rapidly deployable, high-bandwidth, reliable, and secure solution for branch offices and remote sites. With 4G LTE data rates, the Cisco 4G LTE WWAN EHWICs offer a primary WAN link solution capable of running comprehensive branch-office services, including voice and video services.
