ASUS WLAN Card 31 Chapter 5 Chapter 5 - Glossary Glossary Each subchannel in the COFDM implementation is about 300 KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125 Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps, data rate. Using quadrature phase shift keying, you can double the amount of data encoded to 250 Kbps per channel, yielding a 12-Mbps data rate. And by using 16-level quadrature amplit ude modula tion encod ing 4 bits per hertz, y ou c an a chieve a dat a ra te o f 24 Mbps. The 802.1 1a/g standard speciï¬Âes that all 802.1 1a/g-compliant products must support these basic data rates. The standard also lets the vendor extend the modulation scheme beyond 24 Mbps. Remember , the more bits per cycle (hertz) that are encoded, the more su sceptible the signal will be to interf erence and fading, and ultimately , the shorter the range, unless power output is increased.

DNS Server Address (Domain Name System) DNS allows Internet host computers to have a domain name and one or more IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a user enters a domain name into the Internet browser , the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned.

34 ASUS WLAN Card Chapter 5 Chapter 5 - Glossary Glossary The 802.1 1b spectrum is plagued by saturation from wireless phones, microwave ovens and other emerging wireless technologies, such as Bluetooth. In contrast, 802.1 1a spectrum is relatively free of interference. The 802.1 1a standard gains some of its performance from the higher frequencies at which it operates.

In addition, RF interference is much less likely because of the less-crowded 5 GHz band. IEEE 802.1 1b (1 1Mbits/sec) In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted th e 802.1 1 standard for wireless devices operating in t he 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.1 1 standard operate at a data rate of either 1 or 2 Mbps. In 1999, the IEEE created the 802.1 1b stand ard. 802 .1 1b is essenti ally id entical to the 802.1 1 standard except 802.1 1b provides for data rates of up to 1 1 Mbps fo r d ire ct s equ enc e sp rea d sp ect rum d ev ice s.

T his p rov id es interoperability with existing 802.1 1 direct sequence devices that operate only at 2 Mbps. Direct sequence spread spectrum devices spread a radio signal over a range of frequencies. The IEEE 802.1 1b speciï¬Âcation allocates the 2.4 GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies.

ASUS WLAN Card 31 Chapter 5 Chapter 5 - Glossary Glossary Each subchannel in the COFDM implementation is about 300 KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125 Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps, data rate. Using quadrature phase shift keying, you can double the amount of data encoded to 250 Kbps per channel, yielding a 12-Mbps data rate. And by using 16-level quadrature amplit ude modula tion encod ing 4 bits per hertz, y ou c an a chieve a dat a ra te o f 24 Mbps. The 802.1 1a/g standard speciï¬Âes that all 802.1 1a/g-compliant products must support these basic data rates. The standard also lets the vendor extend the modulation scheme beyond 24 Mbps. Remember , the more bits per cycle (hertz) that are encoded, the more su sceptible the signal will be to interf erence and fading, and ultimately , the shorter the range, unless power output is increased.

DNS Server Address (Domain Name System) DNS allows Internet host computers to have a domain name and one or more IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a user enters a domain name into the Internet browser , the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned. DSL Modem (Digital Subscriber Line) A DSL modem uses your existing phone lines to transmit data at high speeds.

T he ch ipping sequenc e is c ombined with a tra nsmitted data stream to produce the output signal. Wireless mobile clients receiving a direc t-sequence transmission use the spreading code to map the chips within the chipping sequence back into bits to recreate the original data transmitted by the wireless device. Intercepting and decoding a direct- sequence transmission requires a predeï¬Âned algorithm to associate the spreading co de us ed b y t he t ra nsm itt in g w ir ele ss d evi ce t o t he r ece iv ing w ir ele ss m obi le client.

34 ASUS WLAN Card Chapter 5 Chapter 5 - Glossary Glossary The 802.1 1b spectrum is plagued by saturation from wireless phones, microwave ovens and other emerging wireless technologies, such as Bluetooth. In contrast, 802.1 1a spectrum is relatively free of interference. The 802.1 1a standard gains some of its performance from the higher frequencies at which it operates. The laws of information theory tie frequency , radiated power and dist ance toget her in an inve rse relati onship. Thus, mo ving up to th e 5- GHz spe ctr um fr om 2. 4 G Hz wi ll le ad to s hort er di sta nce s, giv en th e s ame r adi ate d power and encoding scheme. Compared with 802.1 1g: 802.1 1a is a standard for access points and radio NICs that is ahead of 802.1 1g in the market by about s ix months. 802.1 1a operates in the 5GHz frequency band with twelve separate non-overlapping channels. As a result, you c an ha ve up t o t welv e a cce ss poi nts s et to d iffer ent ch ann els in t he sa me area wit hout them i nterferin g wi th e ach other .

In addition, RF interference is much less likely because of the less-crowded 5 GHz band. IEEE 802.1 1b (1 1Mbits/sec) In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted th e 802.1 1 standard for wireless devices operating in t he 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.1 1 standard operate at a data rate of either 1 or 2 Mbps. In 1999, the IEEE created the 802.1 1b stand ard. 802 .1 1b is essenti ally id entical to the 802.1 1 standard except 802.1 1b provides for data rates of up to 1 1 Mbps fo r d ire ct s equ enc e sp rea d sp ect rum d ev ice s.

T his p rov id es interoperability with existing 802.1 1 direct sequence devices that operate only at 2 Mbps. Direct sequence spread spectrum devices spread a radio signal over a range of frequencies. The IEEE 802.1 1b speciï¬Âcation allocates the 2.4 GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies. IEEE 802.1 1g 802.1 1g is a new extension to 802.1 1b (used in majority of wireless LANs today) th at br oad en s 8 02. 1 1 b' s d ata r at es to 5 4 Mb ps wi thi n th e 2 .4 GH z ba nd us ing OF DM ( ort ho go nal fr equ en cy d iv isi on m ul tip le xi ng ) t ec hno lo gy . 8 02 .1 1 g al lo ws b a c k w a r d c o m p a t i b i l i t y w i t h 8 0 2 . 11 b d e v i c e s b u t o n l y a t 11 M b p s o r l o w e r, depending on the range and presence of obstructions.
