Cisco 4G LTE 2.0 Enhanced High-Speed WAN
Interface Cards

The Cisco

Fourth-Generation (4G) Long-Term Evolution (LTE) Enhanced High-

Speed WAN Interface Cards (EHWICs) for Cisco Integrated Services Routers
Generation 2 (ISR G2) provide the next generation of wireless WAN primary,
backhaul, or backup solutions.

Product Overview

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 such as parallel networks, primary

connection, failover, in-vehicle, network convergence, and wireless WAN diversity. The 4G LTE EHWICs with ISR

G2 is the industry leader to bring enterprise grade wireline 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 (Figure 1) are the first enterprise-class 4G multimode 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

9 LTE standards. Cisco 4G multimode 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 Cisco 4G LTE WWAN 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.

The Cisco 4G LTE WWAN EHWICs include the following models:

●

EHWIC-4G-LTE-AU and EHWIC-4G-LTE-GB: Multimode LTE for carriers that operates LTE on 800-MHz

(band 20), 900-MHz (band 8), 1800-MHz (band 3), 2100-MHz (band 1), or 2600-MHz (band 7) networks;

the multimode LTE Australia and Global EHWICs are backward compatible with DC-HSPA+, HSPA+,

HSPA, UMTS, EDGE, and GPRS.

●

EHWIC-4G-LTE-AT and EHWIC-4G-LTE-CA Multimode LTE for carriers that operates LTE on PCS 1900-

MHz (band 2), 1700/2100-MHz (band 4 AWS), 850 MHz (band 5), 700-MHz (band 17); the multimode LTE

ATT and Canada EHWICs are backward compatible with DC-HSPA+, HSPA+, HSPA, UMTS, EDGE, and

GPRS.
