Appendix 3: Glossary
802.11b - The 802.11b standard specifies a wireless networking at 11
Mbps using direct-sequence spread-spectrum (DSSS) technology and
operating in the unlicensed radio spectrum at 2.4GHz, and WEP encryption
for security. 802.11b networks are also referred to as Wi-Fi networks.
802.11g - It is specification for wireless networking at 54 Mbps using
direct-sequence spread-spectrum (DSSS) technology, using OFDM
modulation and operating in the unlicensed radio spectrum at 2.4GHz, and
backward compatibility with IEEE 802.11b devices, and WEP encryption for
security.
802.1x - 802.1x is a framework for authenticated MAC-level access
control, defines Extensible Authentication Protocol (EAP) over LANs
(WAPOL). The standard encapsulates and leverages much of EAP, which
was defined for dial-up authentication with Point-to-Point Protocol in RFC
2284.Beyond encapsulating EAP packets, the 802.1x standard also defines
EAPOL messages that convey the shared key information critical for
wireless security.
Ad hoc Mode - The 802.11 standard define two modes: infrastructure
mode and ad hoc mode. Ad hoc mode (also called peer-to-peer mode or
an Independent Basic Service Set, or IBSS) is simply a set of 802.11
wireless stations that communicate directly with one another without using
an access point or any connection to a wired network. This mode is useful
for quickly and easily setting up a wireless network anywhere that a
wireless infrastructure does not exist or is not required for services, such
as a hotel room, convention center, or airport, or where access to the
wired network is barred (such as for consultants at a client site).
AES (Advanced Encryption Standard) - Security issues are a major
concern for wireless LANs, AES is the U.S. government’s next-generation
cryptography algorithm, which will replace DES and 3DES
DDNS (Dynamic Domain Name System) - The capability of assigning a
fixed host and domain name to a dynamic Internet IP Address.
DHCP (Dynamic Host Configuration Protocol) - A protocol that
automatically configure the TCP/IP parameters for the all the PCs that are
connected to a DHCP server.
