Seamless Roaming, Independent of Location, Movement, or Infrastructure

Mission-critical applications require always-on connection. The Cisco 3200 Mobile Access Router can exploit any

standard wireless technology, including 802.11b, Cellular Digit Packet Data (CDPD), general packet radio service

(GPRS), and satellite because IP trafﬁc remains independent of transmission medium. Through multiple network

interfaces, the router can communicate with today's wireless WANs and future wireless technologies. The mobile IP

feature allows network nodes to roam across multiple wired or wireless networks and maintain a live connection to

an IP network—a key requirement in mobile computing environments.

Cisco extends the beneﬁts of mobile IP through the introduction of the Cisco IOS Mobile Networks feature in Cisco

IOS Software. Cisco IOS Mobile Networks allows an entire network—not just a single client—to stay connected

while in motion. With Cisco IOS Mobile Network, devices connected to the Cisco 3200 Mobile Access Router, such

as laptops, PDAs, and cameras, can maintain continuous access to the IP network and also share the single or

multiple WAN connections provided by the router.

Consider as an example of seamless mobility a police car equipped with a Cisco 3200 Mobile Access Router driving

through a large metropolitan area. As the car begins in an area with 802.11b wireless Ethernet, for example, it is on

a node on the police LAN. Devices in the car can access information such as a criminal database or streaming voice

and video from a surveillance camera while moving through the city. When the vehicle moves beyond range of the

wireless Ethernet network, the Cisco 3200 Mobile Access Router enables a seamless changeover to another wireless

network—a radio access network, for example. The police ofﬁcers in the car are unaware of this change because they

retain constant connectivity to their mission-critical applications.

High Performance in a Compact, Rugged Design for Use in Vehicles

The Cisco 3200 Mobile Access Router addresses the harsh environment inﬂicted upon electronic devices in moving

vehicles, ships, and aircraft. These environments often impose severe limitations on space and power, and the

consequences of motion can disrupt gear not speciﬁcally hardened for such deployments.

The compact, rugged design of the Cisco 3200 Mobile Access Router addresses these limitations with an

industry-standard PC/104-Plus architecture without sacriﬁcing performance. The board layout and component

placement allow systems integrators to build rugged systems for the most demanding environments. The high-speed

processor, high-speed Personal Computer Interface (PCI) communications bus, and high-capacity memory enable the

high performance required to support advanced IP applications.

Stacking multiple PC/104-Plus cards offers conﬁguration ﬂexibility of various LAN and WAN interfaces to meet

speciﬁc connectivity requirements. Industrial-grade components and extended operating ranges meet the stringent

requirements for extreme conditions encountered by military vehicles such as aircraft. The combination of the small

size, rugged design, and high performance make the Cisco 3200 Mobile Access Router a unique solution for

extending valuable IP applications and connectivity to mobile users operating in extreme conditions.

Advanced IP Services and Interoperability with Cisco IOS Software

Most enterprise and service provider networks throughout the world today run Cisco IOS Software because of its

proven reliability, scalability, and manageability. Cisco extends this feature-rich and resilient software to the extreme

mobile edge, where it provides rich, advanced IP services. Security features include ﬁrewall protection and encrypted

virtual private networks (VPNs) to keep data secure over a public WAN infrastructure. Quality-of-service (QoS)

features enable simultaneous access to several applications over a single WAN connection and protect delay-sensitive

trafﬁc such as video.
