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.
Antenna Gain
Antenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width.
Higher antenna gain improves the range of the signal for better communications.
For an indoor site, each 1 dB increase in antenna gain results in a range increase of approximately
