Archer C20i AC750 Wireless Dual Band Router - 130 - Appendix D: Glossary ¾ 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). 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) [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. 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.   ¾ DSL  (Digital  Subscriber  Line)  - A technology that allows data to be sent or received over existing traditional phone lines. ¾ ISP (Internet Service Provider) - A company that provides access to the Internet.
Archer C20i AC750 Wireless Dual Band Router - 131 - ¾ MTU (Maximum Transmission Unit) - The size in bytes of the largest packet that can be transmitted. ¾ NAT (Network Address Translation) - NAT technology translates IP addresses of a local area network to a different IP address for the Internet. ¾ PPPoE (Point to Point Protocol over Ethernet) - PPPoE is a protocol for connecting remote hosts to the Internet over an always-on connection by simulating a dial-up connection. ¾ 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.   ¾ WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or 152-bit shared key algorithm, as described in the IEEE 802.11 standard.   ¾ 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. ¾ 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.
