Antenna Mode
You are presented with three options for the type of antenna you have
connected to the Cisco Wireless LAN Adapter. They are as follows:
Antenna Diversity - This allows the Cisco Wireless LAN Adapter 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) might not be. Therefore, the Cisco Wireless LAN Adapter
would automatically select the antenna that has the highest signal strength.
This is the recommended setting for the standard snap on antenna.
Right Antenna Only - If you are not using the standard snap on antenna, choose
this option if the antenna you are using is connected to the right-hand
antenna port (denoted J1). This tells the Cisco Wireless LAN Adapter not to attempt
to communicate using the left-hand antenna port (J2), since no antenna is
connected to it.
Left Antenna Only - If you are not using the standard snap on antenna, choose
this option if the antenna you are using is connected to the left-hand antenna
port (denoted J2). This tells the Cisco Wireless LAN Adapter not to attempt to
communicate using the right-hand antenna port (J1), since no antenna is
connected to it.
