Appendix D: Glossary
 802.11ax - 802.11ax is a wireless networking standard in the 802.11 family by adding
OFDMA,
MU-MIMO (which is marketed under the brand name Wi-Fi 6), developed in
the IEEE Standards Association process, providing
high-throughput wireless local area
networks
(WLANs) on the 5GHz band 20、40、80、160MHz.
 802.11ac - 802.11ac is a wireless networking standard in the 802.11 family by adding
MU-MIMO (which is marketed under the brand name Wi-Fi 5), developed in the IEEE
Standards Association process, providing
high-throughput wireless local area networks
(WLANs) on the 5GHz 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 2.4GHzHz, 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 2.4GHzHz, 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
