Wireless Mobile Interface Card (WMIC)
The Wireless Mobile Interface Card (WMIC) is a mobile interface card (MIC) in a standard PC/104-Plus
form factor. It is one component of the Cisco 3200 Series Mobile Access Routers and provides a
2.4-GHz (802.11b/g) or 4.9-GHz (US Only, Public Safety) wireless interface.
The WMIC can be configured as a:
• Wireless Access Point
• Wireless Root Bridge
• Wireless Non-root Bridge
• Wireless Work Group Bridge.
The WMIC communicates with the router through its 10/100 Fast Ethernet interface.
Note This chapter provides basic information about the WMIC hardware for the purpose of performing simple
troubleshooting, such as reconnecting a loose cable. To solve more difficult problems, please contact
your vendor.
Caution The 4.9-GHz (US Only, Public Safety) radio requires an operators license and can only be operated by
US Public Safety operators who meet the requirements specified under FCC Part 90.20.
WMIC Component Systems
The ISA buses and PCI buses on the Cisco 3200 Series Mobile Access Router cards provide power to
the components on the cards. The WMIC does not receive or transmit communications signals on the
buses, but it will pass signals through to a card above or below the WMIC. Both buses comply with the
PC/104-Plus standard.
The PCI bus signals allow the Cisco cards to communicate. Non-Cisco cards cannot communicate with
the Cisco 3200 Series Mobile Access Router cards over the PCI bus.
Caution If you add non-Cisco cards that generates signals on the PCI bus, the router might shut down. Please do
not add non-Cisco cards that generate signals on the PCI bus.
