 24 Appendix A: Glossary  108M  Super  GTM  WLAN  Transmission  Technology -  108M  Super  GTM  WLAN Transmission Technology employs multiple performance-enhancing techniques including packet bursting, fast frames, data compression, and dynamic turbo mode that combine to improve the throughput and range of wireless networking products. Users can experience link rates of up to 108Mbps, twice the industry-standard maximum data link rate of 54Mbps, while  preserving  full  compatibility  with  traditional  802.11g  or  802.11b  networks.  108M Super  GTM products  offer  the  highest  throughput  performance  available  on  the  market today.  In  dynamic  108M  mode,  the  device  can  attach  802.11b,  802.11g  and  108Mbps Super GTM devices at the same time in an integrated environment.  2x to 3x eXtended RangeTM WLAN Transmission Technology - The WLAN device with 2x to 3x eXtended RangeTM WLAN transmission technology make its sensitivity up to 105 dB, which  gives  users  the  ability  to  have  robust,  longer-range  wireless  connections.  With  this range-enhancing technology, a 2x to 3x eXtended RangeTM 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 eXtended RangeTM 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 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.  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.  Ad-hoc  Network  -  An  ad-hoc  network  is  a  group  of  computers,  each  with  a  wireless 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.    DSSS (Direct-Sequence Spread Spectrum) - 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  for  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).  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.  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
 25 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).  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 promoting interoperability among 802.11b devices.  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.  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.
