B-11

Advanced (Infrastructure)

The following parameters are contained in both the Infra-

structure and Ad Hoc Modes:

• Antenna Mode

• Speciﬁed Access Point

• RTS Threshold

• RTS Retry Limit

Antenna Mode

Three options are available for the type of antenna you

have connected to the Aironet 4000 Series Wireless

LAN Adapter:

• Antenna Diversity: This allows the PC Card to use

the stronger signal from the two antenna ports.

Diversity can help the radio maintain the RF

connection in areas of interference. Due to the

nature of how RF signals are affected by the

surroundings, one antenna may be in an RF “null”

where the signal is very weak, but the other

antenna (even though it is only a small distance

away) may have a stronger signal strength. The PC

Card would automatically select the antenna that

has the highest signal strength. Antenna Diversity

is the recommended setting for the standard

Snap-On antenna.

• Right Antenna Only (J1): Choose this option if the

antenna you are using is connected to the right

hand antenna port and you are not using the

standard Snap-On antenna. The PC Card will not

attempt to communicate using the left hand

antenna port since no antenna is connected to it.
