Appendix A: Glossary
TM
WLAN Transmission Technology - The WLAN device with 2x to
2x to 3x eXtended Range
TM
3x eXtended Range WLAN transmission technology make its sensitivity up to 105 dBm, which
gives users the ability to have robust, longer-range wireless connections. With this
TM
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
TM
and 802.11g product transmission distance is about 300m, A 2x to 3x eXtended Range based
client and access point can maintain a connection transmission distance 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.
Access Point (AP) - A wireless LAN transceiver or "base station" that can connect a wired LAN to
one or many wireless devices. Access points can also bridge to each other.
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.
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.
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.
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
