Appendix D: Glossary

 802.11ac - IEEE 802.11ac is a wireless computer networking standard of 802.11.This

specification will enable multi-station WLAN throughput of at least 1 gigabit per second .This is

accomplished by extending the air interface concepts embraced by 802.11n: wider RF

bandwidth, more MIMO spatial streams, multi-user MIMO, and high-density modulation (up to

256 QAM).

 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.

 DDNS (Dynamic Domain Name System) - The capability of assigning a fixed host and domain

name to a dynamic Internet IP Address.
