Appendix D: Glossary

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) [3] 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.
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 - 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.
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.
ISP (Internet Service Provider) - A company that provides access to the Internet.

SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key

identifying a wireless local area network. For the wireless devices in a network to
communicate with each other, all devices must be configured with the same SSID. This is
typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in
the wireless Access Point and to the wireless network name.
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit

shared key algorithm, as described in the IEEE 802.11 standard.
Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the Wireless

Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards
group promoting interoperability among 802.11b devices.
WLAN (Wireless Local Area Network) - A group of computers and associated devices

communicate with each other wirelessly, which network serving users are limited in a local
area.
