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

supplement traditional wireline 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.

Key Business Benefits: Extending the Enterprise to the Small Branch Office

The Cisco 819 is designed to extend the IP network from an enterprise out to a small remote or branch office such

as an ATM, kiosk, or mobile infrastructure over a secure, persistent, and reliable connection. Powered by the

award-winning Cisco IOS Software, the Cisco 819 supports advanced security features including firewall, intrusion

prevention, content filtering, and encryption for VPNs; and QoS features for optimizing voice and video

applications in these remote sites, offering end users the experiences and services they have in the enterprise.

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.

Network Security, Reliability, and Manageability

Cisco IOS Software, which powers the Cisco 819, provides capabilities for network security, manageability, and

scalability. It offers integrated network security features, including authorization and authentication, stateful

firewall, intrusion detection, and Triple Digital Encryption Standard (3DES) or Advanced Encryption Standard

(AES) encryption for VPNs. Support for extensive 3G, 3.5G and 3.7G MIBs and remote-management capabilities

gives network managers visibility into and control of devices, including devices connected to the router in these

remote sites. Powerful debug and troubleshooting commands allow network managers to quickly isolate network

problems and securely make changes to network configurations.

Retail VPN

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

wireless 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.

Managed Services

Service providers and value-added resellers can use the Cisco 819 as a platform to offer differentiated business-

class security and wireless LAN (WLAN) services for small and medium-sized business (SMB) customers.

Superior management capabilities such as Simple Network Management Protocol (SNMP) support with 3G MIB

and Cisco Configuration Professional make remote management and provisioning easier.
