Security Parameters Summary
Refer to this table to see what other security parameters you should configure for each authentication
method or key management protocol type. MAC address filters are not dependent on how you
configure these security features.
Antenna Overview
An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the
antenna, which propagates the signal through the air. The antenna also operates in reverse by
capturing RF signals from the air.
Positioning the antennas properly increases the range and coverage area of a wireless LAN.
Antenna Characteristics
Frequency
An antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz (IEEE 802.11a) is needed
to communicate efficiently in a wireless LAN
Radiation Pattern
A radiation pattern is a diagram that allows you to visualize the shape of the antenna’s coverage area.
