hospitals, banks, and mobile fleets, for example to intelligently redirect web traffic to the cloud to enforce

granular security and acceptable use policies over user web traffic. With this solution, you can deploy

market-leading web security quickly and easily to protect branch office users from web-based threats, such

as viruses, while saving bandwidth, money, and resources.

With enhanced data rates and improved latency (below 100 milliseconds), WWAN services are an ideal

way to supplement traditional wire line services. Third- and fourth-generation WWAN data services offered

today have average data rates well in excess of ISDN speeds, with theoretical limits in excess of 21 Mbps

on the downlink and 5.76 Mbps on the uplink. The 3G and 4G LTE WWAN can be used as a primary link for

sites with lower bandwidth requirements and for mobile applications. The 3G and 4G LTE WWAN data

services can also be used as a cost-effective alternative in areas where broadband services are either not

available or very expensive. Cisco is building on these performance milestones and adding support for

wireless to our wide variety of WAN interface alternatives.

Business Benefits and Application Examples

Businesses are looking for ways to reduce costs, increase revenue, and improve business continuity. The 4G LTE

wireless connectivity, which is 10 to 15 times faster and has 5 times lower latency than 3G links, allows a small

enterprise branch office or remote office to set up comprehensive media services in a matter of hours, without

worrying about availability of broadband services and the need for laying down the lines. Wireless carriers offer

flexible, usage-based data plans that can be catered to meet the needs and price points of the business customer.

As WAN backup alternatives, 3G and 4G LTE wireless offer greater WAN diversity and resiliency because they are

independent of the local terrestrial infrastructure. The Cisco 819 enables businesses to stay productive during

service provider downtime or a network failure.

Ability to Host Networks in Motion

The Cisco 819 uses standards-based Mobile IP features in Cisco IOS Software to host networks in motion.

Transition to different wireless networks is transparent to the users and devices (such as laptops, smart devices,

and surveillance cameras), and applications maintain continuous connectivity without the user’s manual

intervention as WAN links change. In addition to allowing a single node or device to stay connected, the Cisco 819

allows an entire mobile network or subnet to stay connected. The dual radio WLAN on the 819 can serve as both a

client and an access-point. The mobile asset (truck, passenger bus, car) can communicate with either a localized

WLAN network as in a bus or train dock or communicate with a city-wide WLAN deployment when in motion.

Retail VPN

Retail stores migrating from dialup connections for point-of-sale transactions can use the 3G, 3.5G or 3.7G (4G?)

wireless WAN option on the Cisco 819 for low-cost broadband access with the required security to comply with

payment-card-industry and other data security requirements. Multiple devices and applications can then be added

to the store network to take advantage of the increased bandwidth and to enable secure mobility and enhance

productivity.
