Operating Instructions SCALANCE W78x

Service Set Identifier (SSID) is used to identify a wireless network
based on IEEE 802.11
Simple Network Management Protocol. Standardized protocol for
transporting network management information.
Temporal Key Integrity Protocol. Scheme for cyclic changing of keys
in WLANs.
The Transmit-Power Control function (TPC) introduced as a
supplementary function by the 802.11h expansion for 5 GHz
components allows an automatic adaptation of the transmit power.
Information on the attenuation values and the expected budget
reserves in received power are taken into account. TPC is also
intended to make sure that the maximum permitted transmit power of
a channel specified by the relevant regulatory bodies is not exceeded
by the component. TPC attempts to operate with the minimum
transmit power between the communicating stations or between
access point and station.
Virtual Access Point. By using virtual access points, various SSIDs
(maximum of 8 per WLAN interface) can be configured with different
security settings. You can assign each virtual AP to a particular VLAN.
Web Based Management. HTTP-based configuration method in which
an HTTP server is used in the SCALANCE W78x.
Wireless Distribution System. Radio links for connecting the access
points for an extended service set (ESS)
WEP (Wired Equivalence Privacy) is an optional part of the IEEE
802.11 standard. WEP specifies methods of authentication and
encryption working with fixed keys stored on the device. All devices
that want to access a network in which WEP is used must first be
supplied with the same keys. WEP works with key lengths between 40
and 128 bits. Occasionally different key lengths are encountered (for
example 256 bits) but these are not intended in the vendor-
independent WLAN standards IEEE 802.11b and 802.11g. The keys
can only be changed manually.
Wireless Fidelity. The Wi-Fi Alliance is a group of WLAN
manufacturers that tests and certifies the interoperability or WLAN
products. Wi-Fi is a certification of WLANs according to 802.11b and
is performed by the WECA of the WiFi parent organization. This
certification confirms the interoperability of WLAN products operating
