Example 4.11. Setting the Distance Parameter
EION: interface Wireless 0 distance 3000
The distance value is set to '3000 meters'.
4.2.4.3. Setting Dynamic Frequency Selection (DFS)
Dynamic Frequency Selection (DFS) is the process of detecting radar signals that must be protected
against 802.11a interference, and upon detection switching the 802.11a operating frequency to one
that is not interfering with the radar systems.

4.2.4.4. Setting Automatic Transmit Power Control (ATPC)
Automatic Transmit Power Control is a technical mechanism used within some networking devices
in order to prevent unwanted interference between different wireless networks. The network devices
supporting this feature are IEEE 802.11h Wireless LAN devices in the 5 GHz band compliant to the
IEEE 802.11a. The idea of the ATPC mechanism is to automatically reduce the used transmission
output power when other networks are within range. Reduced power means reduced interference
problems and increased battery capacity. The power level of a single device can be reduced by 6 dB
which should result in an accumulated power level reduction (the sum of radiated power of all devices
currently transmitting) of at least 3 dB (which is half of the power).
