Wireless Mobile Interface Cards


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 with the following:

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 be operated only by US Public Safety operators who meet the requirements specified under FCC Part 90.20.

This chapter provides basic information about the WMIC hardware for performing simple troubleshooting, such as reconnecting a loose cable. To solve more difficult problems, 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. Do not add non-Cisco cards that generate signals on the PCI bus.

Figure 6-1 shows the WMIC header and bus locations.

Note The PC/104-Plus standard requires that the PCI bus and the ISA bus use keying features in the standard stacking headers to guarantee proper module installation. On the PCI bus, pin D30 is removed and its opening is plugged. On the ISA bus, pin C19 and pin B10 are removed, and their openings are plugged.


Antenna Connector

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

The cable should be as short as possible to minimize the loss in strength of the RF signal. The cable carries the RF signal from the antenna to the low noise amplifier (LNA) on the receiver and carries the RF signal from the 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 the Cisco 3200 Series router card and the PCI Serial Mobile Interface Card (SMIC) and between the SMIC and the Fast Ethernet Switch Mobile Interface Card (FESMIC).

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.

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 configured through 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 Cisco 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 EIA/TIA-232 console ports replace two Fast Ethernet ports on the end cap.


Note At present, 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 EIA/TIA-232 ports are sealed.


Fast Ethernet Signals on the WMIC

The Fast Ethernet signals are delivered through a 10-pin header. LED signals and EIA/TIA-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 comply with IEEE 802.3. The signals are provided through the Ethernet headers, which support the following:

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


LED Behavior

During normal operations, the indicator signals (LEDs) on the wireless device have the following meanings:

The status indicator signals operational status. Steady green indicates that the wireless device is associated with at least one wireless client. Blinking green indicates that the wireless device is operating normally but is not associated with any wireless devices.

The radio indicator blinks green to indicate radio traffic activity. The light is normally off, but it blinks whenever a packet is received or transmitted over the radio.

The Ethernet indicator signals traffic on the wired LAN. This indicator is normally green when an Ethernet cable is connected. The indicator blinks green when a packet is received or transmitted over the Ethernet infrastructure. The indicator is off when the Ethernet cable is not connected.

Table 6-1 lists the details of LED indicator signals.

Universal Workgroup Bridge Limitations

The following limitations and restrictions apply to universal workgroup bridges:

A universal workgroup bridge cannot associate with the Cisco WLAN AP when the bridge is configured with CKIP or CMIC encryption.

If the universal workgroup bridge is associated with a Cisco AP or third-party AP and if the user issues the show dot11 association all command, the IP address and name information is not available.

Users should configure the static IP address on the Bridge-Group Virtual Interface (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 Collocated Care-of Address (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 cannot associate with the Cisco 1500 router when it is configured with the Allow WPA2 TKIP Clients option.

The 5.0-GHz (802.11h) radio in the Cisco 3200 Series router (currently available as the Cisco 3205 WMIC) supports the following channels and 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.)


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 Cisco 3205 WMIC by using the command-line interface (CLI), see the "Configuring the Radio Channel or Frequency for the C3205 WMIC" section in the Radio Channels and Transmit Frequencies document. To see Dynamic Frequency Selection (DFS) statistics, use the show interface d0 dfs command.


Throughput

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 equivalent isotropically radiated power (EIRP)

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