Wireless Mobile Interface Cards (WMICs)

The Cisco Wireless Mobile Interface Card (WMIC) is a Cisco 3200 Series router interface card in a
standard PC/104-Plus form factor.

It is one component of the Cisco 3200 Series routers and provides a wireless interface:

• 2.4 GHz (802.11b/g) – Cisco 3201

• 4.9 GHz (public safety) – Cisco 3202

• 5.0 GHz (802.11h) – Cisco 3205 (The C3205WMIC-K9 and C3205WMIC-TP-K9 WMICs are

available only in the European Telecommunications Standards Institute [ETSI] domain.)

Caution The 4.9 GHz (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.

This chapterprovidesbasic 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.

WMIC Component Systems

The ISA buses and PCI buses on the Cisco 3200 Series router cards provide power to the components
on the cards. The WMIC does not receive or transmit communications signals on either bus, but it will
pass signals through the bus 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 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.

5 10-pin Fast Ethernet header 6 24-pin multifunction header

Note The PC/104-Plus standard requires that the PCI bus and the ISA bus utilize keying features in the

standard stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed
and the D30 opening is plugged. On the ISA bus, pin C19 and pin B10 are removed, and the C19 and
B10 openings are plugged.

Antenna Connector

On the radio card, there are two ultra-miniature coaxial connectors (U.FL connector) that are used to
connect the coax cables between the WMIC and the external antenna connectors. Two connectors are
used to support antenna diversity.

The cable should be as short as possible to minimize the loss in strength of the radio frequency (RF)
signal. The cable carries the RF signal from the antenna to the low noise amplifier (LNA)on the receiver
and transmits the RF signal from power amplifier (PA) to the antenna that radiates the RF signal.

There are many antenna connector families. The Cisco RP-TNC antenna connector can be used to
support standard antennas.

WMIC Console and Fast Ethernet Ports

Cisco 3200 Series router cards do not support any ISA bus signals. The PCI bus connector supports
communication between Cisco 3200 Series router card and the Fast Ethernet Switch Mobile Interface
Card (FESMIC) and Serial Mobile Interface Card (SMIC).

In a Cisco rugged enclosure, the WMIC communicates with the router through the WMIC Fast Ethernet
interface. The WMIC Fast Ethernet ports are connected internally to Fast Ethernet ports that provide a
communications link with the router.

OL-5816-09

Chapter 6 Wireless Mobile Interface Cards (WMICs)

The WMIC interfaces are configured through a WMIC console port. In contrast, the Serial Mobile
Interface Card (SMIC) and FESMIC communicate with the router through the PC/104-Plus bus. The
interfaces are configuredthrough the router console port, and all of the router and FESMIC Fast Ethernet
ports are identified by using the slot/port format.

The WMIC runs an independent IOS image and when it is configured, the link between the WMIC and
the router forms an internal LAN. In standard configurations, a WMIC Fast Ethernet port is never
brought out to the end cap.

The WMIC console port is brought out to the corresponding RJ-45 port on the I/O end cap, replacing a
Fast Ethernet port. If the router includes one WMIC, the RS-232 WMIC console port replaces a Fast
Ethernet port on the end cap. If the router includes two WMICs, two WMIC RS-232 console ports
replace two Fast Ethernet ports on the end cap.

Note Currently, even if the router contains zero WMICs, in standard configurations a maximum of three Fast

Ethernet ports are brought out to the end cap. Unused RS-232 ports are sealed.

Fast Ethernet Signals on the WMIC

The Fast Ethernet signals are delivered through a 10-pin header. LED signals and RS-232 console signals
are provided through the 24-pin multifunction header.

There is one set of fixed Fast Ethernet signals on the WMIC. The Fast Ethernet port signals are in
compliance with IEEE 802.3. They are provided through the Ethernet headers, which support the
following:

• Auto-negotiation for 10/100BASE-TX connection

• Full-duplex and half-duplex modes

• Low-power sleep mode

• 10BASE-T and 100BASE-TX using a single Ethernet connection

• Robust baseline wander correction performance

• Standard carrier signal multiple access collision detect (CSMA/CD) or full-duplex operation

• Integrated LED drivers

Note If Auto-MDIX is disabled, when connecting to Ethernet switches or repeaters a straight-through cable

can be used. When connecting to compatible workstations, servers, and routers, a crossover cable should
be used. If Auto-MDIX is enabled, either a straight-through or crossover cable can be used can be used
to make the connection, as the router automatically changes the signals on the pins to compensate.

Universal Workgroup Bridge Limitations

The following limitations and restrictions apply to universal workgroup bridges:

• A universal workgroup bridge can not associate with the Cisco WLAN AP with CKIP or CMIC

encryption configuration.

• If the universal workgroup bridge is associated with a Cisco AP or third party AP and if the user

issues the command show dot11 association all, the IP address and name information is not
available.

• Users should configure the static IP address on the BVI when it is in the universal workgroup bridge

mode, so that the WMIC is manageable from the MAR through the Mobile IP tunnel from the
infrastructure side.

• If the dynamic CCoA is used on the Cisco 3200 Series Wireless and Mobile Router, you should

configure the static IP address using the ip secondary address command.

• The universal workgroup bridge is not compatible with the Tropos version 3.1.1.2 AP.

• A universal workgroup bridge can not associate with the Cisco 1500 router when it is configured

with the Allow WPA2 TKIP Clients option.

Note By default, the C3205 WMIC uses the right antenna to receive and transmit data.

5.0-GHz (802.11h) Channels

The 5.0-GHz (802.11h) radio in the Cisco 3200 Series router (currently available as the Cisco 3205
WMIC) supports the following channels/frequencies in the ETSI regulatory domain:

• 5.250 GHz to 5.350 GHz: 5260 MHz (52), 5280 MHz (56), 5300 MHz (60), 5320 MHz (64),

• 5.470 GHz to 5.725 GHz: 5500 MHz (100), 5520 MHz (104), 5540 MHz (108), 5560 MHz (112),

5580 MHz (116), 5600 MHz (120), 5620 MHz (124), 5640 MHz (128), 5660 MHz (132),
5680 MHz (136), 5700 MHz (140). (Channels 52 through 140 are ETSI outdoor channels.)

Throughput

Chapter 6 Wireless Mobile Interface Cards (WMICs)

Note By default, the C3205 WMIC performs automatic channel selection on the radio interface. For more

information about configuring a channel on the radio interface of the C3205 WMIC using the
command-line interface (CLI), refer to the “Configuring the Radio Channel or Frequency for the C3205
WMIC” section in the Radio Channels and Transmit Frequenciesdocument. The show interface d0 dfs
command provides DFS statistics.

The throughput is a minimum of 16 Mbps half-duplex at one mile line-of-sight range for a
20 MHz-wide channel. The range performance is dependent on output power, antenna gain,
path loss, and other factors.

The following are range performance estimations:

• 6 Mbps at 10 kilometers (6 miles) at 30 dBm EIRP

• 1 Mbps at 30 kilometers (18 miles) at 30 dBm EIRP
