Glossary of Terms
Description
The following table lists the terms and their definitions used in this document.
3DES
Triple Data Encryption Standard. 3DES is a symmetric-key block cipher that
applies the DES cipher algorithm three times to each data block.
3G
Third Generation of Wireless Mobile Telecommunications Technology. See
W-CDMA.
3GPP
Third Generation Partnership Project. 3GPP is a collaborative project aimed
at developing globally acceptable specifications for third generation mobile
systems.
4G
Fourth Generation of Wireless Mobile Telecommunications Technology. See
LTE.
802.11
802.11 is an evolving family of specifications for wireless LANs developed by
a working group of the Institute of Electrical and Electronics Engineers
(IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multi-
ple Access with collision avoidance (CSMA/CA) for path sharing.
802.11 bSec 802.11 bSec is an alternative to 802.11i. The difference between bSec and
standard 802.11i is that bSec implements Suite B algorithms wherever pos-
sible. Notably, Advanced Encryption Standard-Counter with CBC- MAC is
replaced by Advanced Encryption Standard - Galois/Counter Mode, and the
Key Derivation Function (KDF) of 802.11i is upgraded to support SHA-256
and SHA-384.
802.11a
802.11a provides specifications for wireless systems. Networks using
802.11a operate at radio frequencies in the 5 GHz band. The specification
uses a modulation scheme known as orthogonal frequency-division multi-
plexing (OFDM) that is especially well suited to use in office settings. The
maximum data transfer rate is 54 Mbps.
802.11ac
802.11ac is a wireless networking standard in the 802.11 family that provides
high-throughput WLANs on the 5 GHz band.
802.11b
802.11b is a WLAN standard often called Wi-Fi and is backward compatible
with 802.11. Instead of the Phase- Shift Keying (PSK) modulation method
used in 802.11 standards, 802.11b uses Complementary Code Keying (CCK)
that allows higher data speeds and makes it less susceptible to multipath-
propagation interference.802.11b operates in the 2.4 GHz band and the max-
imum data transfer rate is 11 Mbps.
