IEEE 802.11
Standard for mobile wireless networks in the 2.4 GHz range with transmission rates of up to
2 Mbps.
IEEE 802.11a
Standard for mobile wireless networks in the 5 GHz range with transmission rates of up to 54
Mbps.
IEEE 802.11b
Standard for mobile wireless networks in the 2.4 GHz range with transmission rates of up to
11 Mbps.
IEEE 802.11e
Enhancement of the wireless LAN standard to support Quality of Service (QoS).
IEEE 802.11g
Standard for mobile wireless networks in the 2.4 GHz range with transmission rates of up to
54 Mbps.
IEEE 802.11h
The IEEE 802.11a standard expanded by TPC and DFS.
IEEE 802.11i
Among other things, the standard describes the WPA2 method, the TKIP procedure and the
AES encryption algorithm. IEEE 802.11i removes a series of weak points in the WEP
security mechanism.
IEEE 802.1x
The heart of the standard is the use of a Radius server as the authentication server. In
addition to this, in IEEE 802.1x, the entire communication is encrypted.
Industrial Ethernet
A bus system complying with IEEE 802.3 (ISO 8802-2)
IP address
The IP address consists of 4 bytes. Each byte is represented in decimal, with a dot
separating it from the previous one. This results in the following structure, where XXX
represents a number between 0 and 255 (dotted decimal notation): XXX.XXX.XXX.XXX
