Operating Instructions SCALANCE W78x

in compliance to the 802.11b standard.  
The Wi-Fi Alliance also develops standards. The WiFi Alliance has 
developed its own architectures for security procedures that have not 
yet been standardized such as the WiFi Protected Architecture (WPA) 
to be able to test the compatibility of the various manufacturers' 
products. 
For real-time transmission, the Wi-Fi Alliance has specified Wi-Fi 
Multimedia (WMM) for transmissions  with guaranteed quality of 
service (QoS). 

WMM 

Wi-Fi Multimedia 

WPA 

WPA (Wi-Fi Protected Access) is a method specified by the Wi-Fi 
Alliance to close security gaps in WEP. Authentication using a server 
is stipulated (802.1x). The dynamic exchange of keys at each frame 
introduces further security. As the encryption method, you can choose 
between TKIP (Temporal Key Integrity Protocol) and AES (Advanced 
Encryption Standard). 
Although WPA never became an official component of the IEEE 
802.11 family of standards, it has become very widespread in a short 
time. This, however, applies only to the WPA procedure described 
above using TKIP. The optional possible implementation of WPA on 
the basis of AES, on the other hand, did not become established and 
is therefore irrelevant in everyday practice. AES only took on practical 
value only with the development of the later WPA2 standard. 

WPA-PSK 

WPA-PSK is a weakened form of WPA. In this method, authentication 
is not established by a server but is based on a password. This 
password must be configured manually on the client and server. 
Wherever possible, you should change to the WPA method to achieve 
greater security.
