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).

FHSS (Frequency Hopping Spread Spectrum) - 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 wireless 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.

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. There are two 

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

Hopping Spread Spectrum (FHSS). 

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.

 

¾ 

WPA  (Wi-Fi Protected Access) - A wireless security protocol use TKIP (Temporal Key 

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