Chapter 4 Wireless Mobile Interface Card (WMIC)
Key Features
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. This low profile
connector offers frequency performance up to 6-GHz. 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.
