Radio Antenna; Leds - Cisco Aironet Installation And Configuration Manual

Hardware Components

Radio Antenna

The type of antenna used depends on your client adapter:
•
•
•
•
•
Refer to the Antenna Mode (Transmit and Receive) parameters in
Note
information on setting the client adapter's antenna mode.
External antennas used in combination with a power setting resulting in a radiated power level above
Note
100 mW equivalent isotropic radiated power (EIRP) are not allowed for use within the European
community and other countries that have adopted the European R&TTE directive or the CEPT
recommendation Rec 70.03 or both. For more details on legal combinations of power levels and
antennas in those countries, refer to the
Directive 1999/5/EC" section on page C-4

LEDs

The client adapters have two LEDs that glow or blink to indicate the status of the adapter or to convey
error messages. Refer to
Note Mini PCI cards do not have LEDs.

PC cards have an integrated, permanently attached diversity antenna. The benefit of the diversity
antenna system is improved coverage. The system works by allowing the card to switch and sample
between its two antenna ports in order to select the optimum port for receiving data packets. As a
result, the card has a better chance of maintaining the radio frequency (RF) connection in areas of
interference. The antenna is housed within the section of the card that hangs out of the PC card slot
when the card is installed.
LM cards are shipped without an antenna; however, an antenna can be connected through the card's
external connector.
PCI cards are shipped with a 2-dBi dipole antenna that attaches to the card's antenna connector.
However, other types of antennas may be used. PCI cards can be operated through the primary (or
right) antenna port only.
Mini PCI cards are designed to be used with either one or two antennas, which connect to the card's
two antenna connectors. If two antennas are used, the radio automatically selects the antenna that
presents the best RF signal. If only one antenna is used, the radio finds and uses it regardless of
which connector it is plugged into.
PC-Cardbus cards have an integrated, permanently attached non-diversity antenna that contains two
antenna ports, one for transmitting and one for receiving. The card cannot switch and sample
between the ports. The antenna is housed within the section of the card that hangs out of the Cardbus
slot when the card is installed.
