Primary Connectivity
For applications that have low data usage but high security requirements such as bank ATMs, gas station kiosks,
point of sales (POS) and telemetry sites, the Cisco 3G WWAN EHWIC offers a secure, simplified, and cost-
effective WAN alternative to DSL or Frame Relay. In areas where terrestrial broadband services (cable, DSL, or
T1) are not available or are expensive, 3G WWAN connectivity can be a viable alternative.
For businesses requiring rapid setup or temporary connectivity, 3G WWAN offers the capability to bring up a new
site quickly and cost-effectively. Using the integrated services available on the Cisco integrated services routers,
Cisco 3G WWAN EHWICs can provide instant and mobile communications during disasters and service outages.
Key Features and Benefits
●
Integrated 3G WWAN broadband: With the 3G WWAN modem integrated into the router, you gain the
benefit of simplified installation and management. In addition, the Cisco 3G WWAN EHWICs are tightly
integrated with Cisco integrated services routers, 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.
●
Short installation time: Businesses sometimes have to wait for weeks or months to get data circuits
installed at new 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.
