Appendix C: Glossary
 802.11ac - 802.11ac is a wireless networking standard in the 802.11 family (which is marketed under the
brand name Wi-Fi), developed in the IEEE Standards Association process, providing high-throughput
wireless local area networks (WLANs) on the 5 GHz band .
 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.
 802.11a - 802.11a was an amendment to the IEEE 802.11 wireless local network specifications that
defined requirements for an orthogonal frequency division multiplexing (OFDM) communication
system. It was originally designed to support wireless communication in the unlicensed national
information infrastructure (U-NII) bands (in the 5–6 GHz frequency range) as regulated in the United
States by the Code of Federal Regulations, Title 47, Section 15.407.
 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.
 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 PC(s) that are connected to a DHCP server.

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.
 DNS (Domain Name System) - An Internet Service that translates the names of websites into IP
addresses.

Domain Name - A descriptive name for an address or group of addresses on the Internet.

DSL (Digital Subscriber Line) - A technology that allows data to be sent or received over existing
traditional phone lines.
 ISP (Internet Service Provider) - A company that provides access to the Internet.
