Appendix D: Glossary
¾ 802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO
(multiple-input multiple-output). MIMO uses multiple transmitter and receiver
antennas to allow for increased data throughput via spatial multiplexing and
increased range by exploiting the spatial diversity, perhaps through coding schemes
like Alamouti coding. The Enhanced Wireless Consortium (EWC) was formed to help
accelerate the IEEE 802.11n development process and promote a technology
specification for interoperability of next-generation wireless local area networking
(WLAN) products.
¾ 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.
¾ 802.11g - 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.
¾ DDNS (Dynamic Domain Name System) - The capability of assigning a fixed host
and domain name to a dynamic Internet IP Address.
¾ DHCP (Dynamic Host Configuration Protocol) - A protocol that automatically
configure the TCP/IP parameters for the all the PC(s) that are connected to a DHCP
server.
¾ DMZ (Demilitarized Zone) - A Demilitarized Zone allows one local host to be exposed
to the Internet for a special-purpose service such as Internet gaming or
videoconferencing.
¾ DNS (Domain Name System) – An Internet Service that translates the names of
websites into IP addresses.
¾ Domain Name - A descriptive name for an address or group of addresses on the
Internet.
