Access Control List. List with MAC addresses with the right to access
the wireless network
Wireless network between individual devices (point-to-point)
Advanced Encryption Standard, Encryption according to the
algorithm.
Address Resolution Protocol
Dynamic Frequency Selection. With the Dynamic Frequency Selection
function (DFS), that is also part of the 802.11h expansion, an
automatic channel change is possible if another user or technical
device is discovered on a channel during operation. This includes, for
example, radar systems that also use the 5 GHz frequency band.
Before a channel is used, it is checked to make sure that no other
system is already using the channel or frequency range. If another
user is discovered, data transmission on the channel is stopped and
there is a change to a different channel.
This avoids influence resulting from WLAN systems operating
according to 802.11a in the 5 GHz band.
Dynamic Host Configuration Protocol
Extensive Authentication Protocol. Authentication protocol.
Ethernet-Client-Module
Two nodes are arranged in a wireless cell so that they are outside the
transmission range of the other station. If they both access the
medium at the same time, collisions result.
