Cisco 4G LTE Wireless WAN Card - Wireless cellular modem - 3G - EHWIC - 100 Mbps - refurbished - for Cisco 1921 4-pair, 1921 ADSL2+, 1921 T1, 19XX, 29XX, 39XX, 39XX ES24
- Integrated 4G LTE WWAN broadband
- Short installation time
- Network resiliency through WAN diversity
- Hardware-ready 4G LTE multiple bearer QoS
The Cisco 4G LTE WWAN EHWIC is the first enterprise-class 4G multimode LTE 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.
Cisco 4G multimode LTE WWAN EHWICs provides persistent, reliable LTE connectivity with fallback and transparent handoff to earlier technologies. The card provides bandwidth to support high-definition (HD) and peer-to-peer (P2P) video calls, providing customers with an excellent mobile broadband experience.

Integrated 4G LTE WWAN broadband
With the 4G LTE WWAN modem integrated into the router, you gain the benefits of simplified installation and management. In addition, the Cisco 4G LTE WWAN EHWIC is tightly integrated with Cisco ISRs, which run the industry-leading Cisco IOS software, giving access to all the advanced features of Cisco IOS software such as quality of service (QoS), intelligent network queuing, and robust security.

Performance
With increasing data use and the proliferation of web-based applications at remote sites, there is an increasing need for high-speed (broadband) data connections to run mission-critical applications at these sites. 4G LTE WWAN services promise low-latency links at high speeds.
-
Short installation time
Businesses sometimes have to wait weeks or months to get data circuits installed at locations. For temporary or seasonal sites, wireless data services allow instant connectivity anywhere there is cellular coverage, and rapid deployment allows you to quickly set up networks with WAN connectivity.
-
Network resiliency through WAN diversity
WAN connectivity is crucial to the functioning of your business, and any downtime means a loss of productivity and lost opportunity. Staying connected and operational during a network outage can be vital. A wireless connection for backup to a remote site provides protection against line outages and an additional level of redundancy because the 4G LTE WWAN infrastructure is often served by separate facilities, providing redundancy for the entire local loop.
-
Hardware-ready 4G LTE multiple bearer QoS
Future alignment with 4G LTE multiple-bearer QoS is supported. The QoS feature is service provider specific, and its support aligns with the service provider's roadmap.
