ASUS WLAN Card 33Chapter 3 - ReferenceChapter 3Windows SettingsConfig - Encryption TabLets you configure the ASUS WLAN Card encryption settings. For dataconfidentiality in a wireless environment, IEEE 802.11 specifies a WiredEquivalent Privacy (WEP) algorithm to offer transmission privacy similar towired network. The WEP uses keys to encrypt transmit data packets and decryptreceived data packets. The encryption process can scramble frame bits to avoiddisclosure to others.Pull Down MenusData encryption (WEP enabled)This option allows you to enable or disable the Wired Equivalent Privacy (WEP)function. If this check box is selected, a WEP Key is used to encrypt your databefore it is transmitted over the air.If you enable WEP encryption, you will only be able to communicate withwireless devices that have use the same WEP keys.WEP KeyThis option is enable only if you enable WEP Encryption. The WEP Key is a64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypttransmit data packets and decrypt received data packets.Key FormatYou can enter the WEP Key as a Hexadecimal digits (0~9, a~f, and A~F), or asASCII characters, based on the state of the Key Format.
34 ASUS WLAN CardChapter 3 - ReferenceChapter 3Windows SettingsKey LengthFor 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCIIcharacters. For 128 bits encryption, each Key contains exactly 26 hex digits, or13 ASCII characters.Two ways to assign WEP keys1. Manual Assignment - When you click this button, the cursor appearsin the field for Key 1. For 64-bit encryption, you are required to enterfour WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, andA~F). For 128-bit encryption, you are required to enter four WEP Keys.Each Key contains exactly 26 hex digits (0~9, a~f, and A~F).2. Automatic Generation - Type a combination of up to 64 letters, num-bers, or symbols in the Passphrase column, then the Wireless SettingsUtility uses an algorithm to generate four WEP Keys for encryption.NOTE: This function ease users from having to remember theirpasswords and is compatible to some existing WLAN utilities, butit is not very secure. "Manual Assignment" is more secure.Default KeyThe Default Key field lets you specify which of the four encryption keys youuse to transmit data on your wireless LAN. You can change the default key byclicking on the down arrow at the right of this field, selecting the number of thekey you want to use and then clicking the Apply button. As long as the AccessPoint or station with which you are communicating has the same key in thesame position, you can use any of the keys as the default.You then click the Apply button to create your encryption keys. After you clickthe Apply button, the Wireless Settings Utility uses asterisks to mask yourkeys.NOTE: Click the Apply or OK button to save the encryption set-tings. The keys you entered will be masked by asterisks.
ASUS WLAN Card 35Chapter 3 - ReferenceChapter 3Windows Settings64/128bits versus 40/104bitsYou may be confused about configuring WEP encryption, especially whenusing multiple wireless LAN products from different vendors. There aretwo levels of WEP Encryption: 64 bits and 128 bits.First, 64 bit WEP and 40 bit WEP are the same encryption method and caninteroperate in the wireless network. This lower level of WEP encryptionuses a 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit“Initialization Vector” (not under user control). This together makes 64bits (40 + 24). Some vendors refer to this level of WEP as 40 bits andothers refer to this as 64 bits. ASUS WLAN products use the term 64 bitswhen referring to this lower level of encryption.Second, 104 bit WEP and 128 bit WEP are the same encryption methodand can interoperate in the wireless network. This higher level of WEPencryption uses a 104 bit (26 Hex character) as a “secret key” (set by user),and a 24 bit “Initialization Vector” (not under user control). This togethermakes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104bits and others refer to this as 128 bits. ASUS WLAN products use theterm 128 bits when referring to this higher level of encryption.Click Apply to save and activate the new configurations.

ASUS WLAN Card 65Chapter 5Chapter 5 - GlossaryGlossaryIEEE 802.11b (11Mbits/sec)In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adoptedthe 802.11 standard for wireless devices operating in the 2.4 GHz frequencyband. This standard includes provisions for three radio technologies: directsequence spread spectrum, frequency hopping spread spectrum, and infrared.Devices that comply with the 802.11 standard operate at a data rate of either 1or 2 Mbps.In 1999, the IEEE created the 802.11b standard. 802.11b is essentially identicalto the 802.11 standard except 802.11b provides for data rates of up to 11 Mbpsfor direct sequence spread spectrum devices. Under 802.11b, direct sequencedevices can operate at 11 Mbps, 5.5 Mbps, 2 Mbps, or 1 Mbps. This providesinteroperability with existing 802.11 direct sequence devices that operate onlyat 2 Mbps.Direct sequence spread spectrum devices spread a radio signal over a range offrequencies. The IEEE 802.11b specification allocates the 2.4 GHz frequencyband into 14 overlapping operating Channels. Each Channel corresponds to adifferent set of frequencies. See the Appendix to determine the center frequencyused by each Channel.If operating multiple 802.11b Wireless ASUS WLAN Cards in the same vicinity,the distance between the center frequencies must be at least 25 MHz to avoidinterference. In the United States, the 802.11b standard allocates 11 operatingChannels for direct sequence devices. Channels 1, 6, and 11 are standard allocates 11 operating Channels for direct sequence devices. Channels independent and do not overlap with each other. To avoid interference between 802.11b Wireless ASUS WLAN Cards, It is recommended that you configure the Wireless ASUS WLAN Cards using only Channels 1, 6, and 11.
66 ASUS WLAN CardChapter 5Chapter 5 - GlossaryGlossaryDirect-Sequence Spread Spectrum (for 802.11b)Spread spectrum (broadband) uses a narrowband signal to spread thetransmission over a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum technique where the transmitted signal is spreadover a particular frequency range. The Space Link Wireless ASUS WLANCard uses Direct-Sequence Spread Spectrum (DSSS) for radio communication.Direct-sequence systems communicate by continuously transmitting a redundantpattern of bits called a chipping sequence. Each bit of transmitted data is mappedinto chips by the Wireless ASUS WLAN Card and rearranged into apseudorandom spreading code to form the chipping sequence. The chippingsequence is combined with a transmitted data stream to produce the WirelessASUS WLAN Card output signal.Wireless mobile clients receiving a direct-sequence transmission use thespreading code to map the chips within the chipping sequence back into bits torecreate the original data transmitted by the Wireless ASUS WLAN Card.Intercepting and decoding a direct-sequence transmission requires a predefinedalgorithm to associate the spreading code used by the transmitting WirelessASUS WLAN Card to the receiving wireless mobile client.This algorithm is established by IEEE 802.11b specifications. The bitredundancy within the chipping sequence enables the receiving wireless mobileclient to recreate the original data pattern, even if bits in the chipping sequenceare corrupted by interference. The ratio of chips per bit is called the spreadingratio. A high spreading ratio increases the resistance of the signal to interference.A low spreading ratio increases the bandwidth available to the user. The WirelessASUS WLAN Card uses a constant chip rate of 11Mchips/s for all data rates,but uses different modulation schemes to encode more bits per chip at thehigher data rates. The Wireless ASUS WLAN Card is capable of an 11 Mbpsdata transmission rate, but the coverage area is less than a 1 or 2 Mbps WirelessASUS WLAN Card since coverage area decreases as bandwidth increases.
ASUS WLAN Card 67Chapter 5Chapter 5 - GlossaryGlossaryIEEE 802.11a (54Mbits/sec)The 802.11b standard was designed to operate in the 2.4-GHz ISM (Industrial,Scientific and Medical) band using direct-sequence spread-spectrum technology.The 802.11a standard, on the other hand, was designed to operate in the morerecently allocated 5-GHz UNII (Unlicensed National Information Infrastructure)band. And unlike 802.11b, the 802.11a standard departs from the traditionalspread-spectrum technology, instead using a frequency division multiplexingscheme that's intended to be friendlier to office environments.The 802.11a standard, which supports data rates of up to 54 Mbps, is the FastEthernet analog to 802.11b, which supports data rates of up to 11 Mbps. LikeEthernet and Fast Ethernet, 802.11b and 802.11a use an identical MAC (MediaAccess Control). However, while Fast Ethernet uses the same physical-layerencoding scheme as Ethernet (only faster), 802.11a uses an entirely differentencoding scheme, called OFDM (orthogonal frequency division multiplexing).The 802.11b spectrum is plagued by saturation from wireless phones, microwaveovens and other emerging wireless technologies, such as Bluetooth. In contrast,802.11a spectrum is relatively free of interference.The 802.11a standard gains some of its performance from the higher frequenciesat which it operates. The laws of information theory tie frequency, radiatedpower and distance together in an inverse relationship. Thus, moving up to the5-GHz spectrum from 2.4 GHz will lead to shorter distances, given the sameradiated power and encoding scheme.
68 ASUS WLAN CardChapter 5Chapter 5 - GlossaryGlossaryCOFDM (for 802.11a/g)Signal power alone is not enough to maintain 802.11b-like distances in an802.11a/g environment. To compensate, a new physical-layer encodingtechnology was designed that departs from the traditional direct-sequencetechnology being deployed today. This technology is called COFDM (codedOFDM). COFDM was developed specifically for indoor wireless use and offersperformance much superior to that of spread-spectrum solutions. COFDMworks by breaking one high-speed data carrier into several lower-speedsubcarriers, which are then transmitted in parallel. Each high-speed carrier is20 MHz wide and is broken up into 52 subchannels, each approximately 300KHz wide. COFDM uses 48 of these subchannels for data, while the remainingfour are used for error correction. COFDM delivers higher data rates and ahigh degree of multipath reflection recovery, thanks to its encoding schemeand error correction.Each subchannel in the COFDM implementation is about 300 KHz wide. Atthe low end of the speed gradient, BPSK (binary phase shift keying) is used toencode 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 ofdata encoded to 250 Kbps per channel, yielding a 12-Mbps data rate. And byusing 16-level quadrature amplitude modulation encoding 4 bits per hertz, youcan achieve a data rate of 24 Mbps. The 802.11a/g standard specifies that all802.11a/g-compliant products must support these basic data rates. The standardalso lets the vendor extend the modulation scheme beyond 24 Mbps. Remember,the more bits per cycle (hertz) that are encoded, the more susceptible the signalwill be to interference and fading, and ultimately, the shorter the range, unlesspower output is increased.Note: This ASUS WLAN device only supports 802.11g and 802.11b.802.11a is supported in other ASUS WLAN products.
