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 TP-LINK 2x to 3x eXtended RangeTM based   client and access point can maintain a connection transmission distance may be up   to 830m.   ¾ ¾ 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.   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.   ¾ 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).   ¾ 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.

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. 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. See also   Wireless Network Name and ESSID.   ¾ 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.   Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the   industry standards group promoting interoperability among 802.11b devices.   ¾ 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.   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.   - 21 -   Download from Www.Somanuals.com.
