Cisco 3200 Series and Wireless Network Access
The Cisco Rugged Enclosure Option for the 3200 Series is designed for in-vehicle use, addressing the
specific mobility needs of the public safety, transportation, defense, and homeland security markets. The
Rugged Enclosure Option is completely sealed and is designed to withstand harsh environments,
including large variations in temperature and altitude, intense shock/vibration, and exposure to
dampness, moisture, or dust.

Cisco 3200 Series and Wireless Network Access
With such a vast array of wireless options and connectivity modes, the Cisco 3200 MAR can deliver
always on IP connectivity for networks in motion. These routers are intended to be mounted in vehicles.
They support Cisco IOS Mobile Networks, and provide the ability to hide the address change that
potentially occurs when roaming between Layer 3 subnets from the local IP nodes. This enables IP hosts
on a mobile network to connect transparently to the network while a router is in motion.

For example, a bus equipped with the 3200 MAR is able to drive around a city while passengers on board
the bus stay connected to the Internet. The client computers do not need any specialized software to
maintain the connections. This transparent communication is accomplished by mobile IP devices that
tunnel packets to the mobile access router, and is discussed further in this chapter.

Release 4.1 of the Cisco Unified Wireless Network has added support for workgroup bridge (WGB)
functionality. Before this feature enhancement, a 3200 MAR would need to use Universal Work Group
Bridge (UWGB) mode to connect to a Cisco Unified Wireless network.
functionality. Before this feature enhancement, a 3200 MAR would need to use Universal Work Group
Bridge (UWGB) mode to connect to a Cisco Unified Wireless network.
By use of WGB, a 3200 MAR can act as a WGB client to a Cisco Unified Wireless Network. Outside of
supporting WGB connections to Cisco 802.11 Unified Wireless Networks, it can be used to connect to
other WLAN solutions that support WGB. The UWGB of the mobile access router is not superseded by
the WGB feature. In fact, it is very useful in environments where you need to connect the 3200 MAR to
802.11 wireless networks that do not support WGB mode. In these types of network connections, the
3200 MAR in UWGB mode is seen as a normal wireless client to the 802.11 wireless network.

Another wireless access method for the 3200 MAR is through use of its wired Fast Ethernet and serial
interface connections. Such connections can be used to integrate cellular and satellite devices. These
device type options are beyond the scope of this document; more information can be found at the
