Appendix: Glossary
2x to 3x eXtended Range WLAN Transmission Technology - The WLAN device with 2x to
3x eXtended Range WLAN transmission technology make its sensitivity up to 105 dB,
which gives users the ability to have robust, longer-range wireless connections. With
this based client and access point can range-enhancing technology, a 2x to 3x
eXtended Range based client and access point can maintain a connection at as much
as three times the transmission distance of traditional 802.11b and 802.11g products,
for a coverage area that is up to nine times greater. A traditional 802.11b and 802.11g
product transmission distance is about 300m, a 2x to 3x based client and access
point can maintain a connection transmission eXtended Rangedistance may be up to
830m.
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.
802.11n - specification for wireless networking at 300/150 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/g devices, and WEP, WAP, WAP2 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.
DoS (Denial of Service) - A hacker attack designed to prevent your computer or
network from operating or communicating.
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.
MTU (Maximum Transmission Unit) - The size in bytes of the largest packet that can be
transmitted.
