WLAN (
W-LAN, Wireless LAN)
Radio network. Network connection is
done using radio waves in the 2.4 GHz
frequency range. Radio networks are
easy to install as no cables have to be
laid but are often problematic and
unreliable, particularly over longer
transmission distances. In many cases,
Power Line networks that also don't
require any cabling are a better choice.
In each case, the installation of a
network cable is the most fault-tolerant
and problem free transmission
technology. An additional point is that
cabled networks don't produce any
electro smog.
WPA
Wi-Fi Protected Access (WPA)
WPA contains the architecture of WEP,
but offers additional protection through
dynamic keys that are based on the
following (Cipher) standards:
- Temporal Key Integrity Protocol (TKIP)
- Advanced Encryption Standard (AES)
WPA offers Pre- Shared Keys (PSK)
for authentication or Extensible
Authentication Protocol (EAP) through
IEEE 802.1x.
The
MMM is based on the
authentication PSK and supports both
the WPA encryption TKIP and AES.
WEP
Wired Equivalent Privacy (WEP) is the
previously used standard encryption
algorithm for WLANs. It should control
access to the network as well as
ensuring the confidentiality and integrity
of the data. Because of various weak
spots, the process is considered to be
unsafe. For this reason, WLAN
installations should use the more
secure WPA encryption. See WPA.
With WPE authentication, a distinction
is drawn between two processes:
Open
Open System Authentication is the
standard authentication. The WEP key
is used at the same time for
authentication: Each client with the
correct WEP key gets access to the
network.
Shared
Shared Key Authentication is reputed to
be the more secure version. In this
case, authentication is done through
the Challenge-Response authentication,
with a secret key. However, the
Challenge-Response process is also
based on WEP and demonstrates the
same weaknesses.
The MMM offers both Open and Shared
WEP authentication.
