Appendix B: Glossary

¾ 802.11b The 802.11b standard specifies a wireless product 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 Ad-hoc Network An ad-hoc network is a group of computers, each with a 300M Mini

Wireless N USB Adapter, connected as an independent 802.11 wireless LAN. Ad-hoc wireless computers operate on a peer-to-peer basis, communicating directly with each other without the use of an access point. Ad-hoc mode is also referred to as an Independent Basic

Service Set (IBSS) or as peer-to-peer mode, and is useful at a departmental scale or SOHO operation.

¾ DSSS ( D irectS equence S pread S pectrum) DSSS generates a redundant bit pattern for all data transmitted. This bit pattern is called a chip (or chipping code). Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the receiver can recover the original data without the need of retransmission. To an unintended receiver,

DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. However, to an intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is recognized as the only valid signal, and interference is inherently rejected (ignored).

¾ FHSS ( F requency H opping S pread S pectrum) FHSS continuously changes (hops) the carrier frequency of a conventional carrier several times per second according to a pseudo-random set of channels. Because a fixed frequency is not used, and only the transmitter and receiver know the hop patterns, interception of FHSS is extremely difficult.

¾ Infrastructure Network An infrastructure network is a group of computers or other devices, each with a 300M Mini Wireless N USB Adapter, connected as an 802.11 wireless LAN. In infrastructure mode, the wireless devices communicate with each other and to a wired network by first going through an access point. An infrastructure wireless network connected to a wired network is referred to as a Basic Service Set (BSS). A set of two or more BSS in a single network is referred to as an Extended Service Set (ESS). Infrastructure mode is useful at a corporation scale, or when it is necessary to connect the wired and wireless networks.

¾ Spread Spectrum Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems.

It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise.

29

PW-DN523 300M Mini Wireless N USB Adapter

There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency

Hopping Spread Spectrum (FHSS).

¾ SSID - A S ervice S et Id entification 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. See also Wireless Network

Name and ESSID.

¾ WEP ( W ired E quivalent P rivacy) 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 ( W ireless L ocal A rea N etwork) - A group of computers and associated devices communicate with each other wirelessly, which network serving users are limited in a local area.

¾ WPA ( W i-Fi P rotected A ccess) A wireless security protocol use TKIP (Temporal Key

Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server.
