DESCRIPTION
If you have two or more NWAs (or other wireless access points) on
your wireless network, you can enable this option so that wireless
devices can change locations without having to log in again. This is
useful for devices, such as notebooks, that move around a lot.
An antenna couples Radio Frequency (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.
