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
their surroundings, one antenna may be in a 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.
