The Mobile IP standard (IETF Standard-RFC 2002) within Cisco IOS Software provides the roaming architecture
that allows a Cisco 3200 Mobile Access Router to connect to its home network. Traditional mobile IP allows client
devicessuch as a laptopcomputer or personal digitalassistant (PDA) tomaintain a single IPaddress and roamamong
multiple networks without losing their connection to the home network. Mobile IP is a network layer functionality,
eliminating the need to rewrite traditional applications.
The Cisco IOS Mobile Network feature allows mobile networks to scale, providing mobility management across the
network.CiscoIOS Mobile Network isan enhanced, standards-based implementationof the Mobile IPstandard that
transforms a Cisco 3200 Mobile Access Router from a mobile IP node into a mobile IP router. All client devices
connectedtothemobile access router can usetherouterIP addresses for mobility.The router and its subnetsmaintain
IP connectivity while the vehicle is in motion. Cisco IOS Mobile Network functionality makes connectivity
transparent to all hosts connecting through the router, because client devices connected to the router require no client
software. With Cisco IOS Mobile Network, mobility is scalable and easier to deploy and manage, and it requires
fewer IP addresses.
A key requirement in both military and public safety deployments is secure communications. Cisco IOS Software
includes a robust set of security features for identity management and confidentiality. Users authenticate themselves
toRADIUS-based identity management servers. Powerful, software-based encryption protects communications from
interception or spoofing. An integrated firewall provides stateful protection. Hardware encryption devices may also
be added externally through the available Ethernet ports on the MARC or FESMIC.

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.
