PCE-N15 WLAN Card User Manual18 ASUS WLAN CardConguration - EncryptionThe Encryption page allows you to set up the encryption settings for your WLAN card. For data condentiality in a wireless environment, IEEE 802.11 species a Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy similar to wired network. WEP uses keys to encrypt data packets sent and decrypt data packets received. The encryption process can scramble frame bits to avoid disclosure to others. Wi-Fi Protected Access (WPA) is an improved security system for 802.11 that encrypts data sent over radio waves. WPA is developed to overcome the weakness of the WEP protocol.Network Authentication - Set up authentication for your WLAN card. Options are: Open - Sets the network operating in the Open System mode that disables authentication protection for the network or use the WEP encryption for the network. Shared - Sets the network operating in the Shared Key mode that uses the WEP encryption for your network. WPA-PSK/WPA2-PSK - Use the WPA Pre-Shared Key/WPA2 Pre-Shared Key in the Infrastructure mode for authentication.Data Encryption - In the Open and Shared authentication modes, options are: Disabled and WEP. Disabled - Disables the encryption protection for your WLAN card. WEP - Encrypts the data before it is transmitted over the air. You can communicate with wireless devices that use the same WEP keys.In the WPA-PSK and WPA2-PSK authentication modes, options are: Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES). TKIP - Dynamically generates unique keys to encrypt data packet. AES - Offers stronger protection and increases the complexity of wireless encryption. It is a symmetric 128-bit block encryption method that works simultaneously on multiple network layers.E6557_PCE-N15_Manual.indd 18 4/8/11 2:56:50 PM
PCE-N15 WLAN Card User Manual19ASUS WLAN CardWireless Network Key (WEP) - This option becomes congurable when you select WEP in the Data encryption eld. 64-bit WEP key uses 5 ASCII characters (10 hexadecimal digits). 128-bit WEP key uses 13 ASCII (26 hexadecimal digits).

PCE-N15 WLAN Card User Manual24 ASUS WLAN CardCOFDM (for 802.11a or 802.11g)Signal power alone is not enough to maintain 802.11b-like distances in an 802.11a/g environment. To compensate, a new physical-layer encoding technology was designed that departs from the traditional direct-sequence technology being deployed today. This technology is called COFDM (coded OFDM). COFDM was developed specically for indoor wireless use and offers performance much superior to that of spread-spectrum solutions. COFDM works by breaking one high-speed data carrier into several lowerspeed subcarriers, which are then transmitted in parallel. Each high-speed carrier is 20MHz wide and is broken up into 52 subchannels, each approximately 300KHz wide. COFDM uses 48 of these subchannels for data, while the remaining four are used for error correction. COFDM delivers higher data rates and a high degree of multipath reection recovery, thanks to its encoding scheme and error correction.Each subchannel in the COFDM implementation is about 300KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125Kbps of data per channel, resulting in a 6,000Kbps, or 6Mbps, data rate. Using quadrature phase shift keying, you can double the amount of data encoded to 250Kbps per channel, yielding a 12Mbps data rate. And by using 16-level quadrature amplitude modulation encoding 4bits per hertz, you can achieve a data rate of 24Mbps. The 802.11a/g standard species that all 802.11a/g-compliant products must support these basic data rates. The standard also lets the vendor extend the modulation scheme beyond 24Mbps. Remember, the more bits per cycle (hertz) that are encoded, the more susceptible the signal will be to interference and fading, and ultimately, the shorter the range, unless power output is increased.Default KeyThis option allows you to select the default WEP key. This option allows you to use WEP keys without having to remember or write them down. The WEP keys generated using the Pass Phrase is compatible with other WLAN products. The Pass Phrase option is not as secure as manual assignment.Device NameAlso known as DHCP client ID or network name. Sometimes provided by an ISP when using DHCP to assign addresses.DHCP (Dynamic Host Conguration Protocol)This protocol allows a computer (or many computers on your network) to be automatically assigned a single IP address from a DHCP server.E6557_PCE-N15_Manual.indd 24 4/8/11 2:56:52 PM
PCE-N15 WLAN Card User Manual25ASUS WLAN CardDNS 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.Direct-Sequence Spread Spectrum (for 802.11b)Spread spectrum (broadband) uses a narrowband signal to spread the transmission over a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum technique where the transmitted signal is spread over a particular frequency range.Direct-sequence systems communicate by continuously transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the output signal.Wireless mobile clients receiving a direct-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 predened algorithm to associate the spreading code used by the transmitting wireless device to the receiving wireless mobile client.This algorithm is established by IEEE 802.11b specications. The bit redundancy within the chipping sequence enables the receiving wireless mobile client to recreate the original data pattern, even if bits in the chipping sequence are corrupted by interference. The ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the resistance of the signal to interference. A low spreading ratio increases the bandwidth available to the user. The wireless device uses a constant chip rate of 11Mchips/s for all data rates, but uses different modulation schemes to encode more bits per chip at the higher data rates. The wireless device is capable of an 11 Mbps data transmission rate, but the coverage area is less than a 1 or 2 Mbps wireless device since coverage area decreases as bandwidth increases.E6557_PCE-N15_Manual.indd 25 4/8/11 2:56:53 PM
PCE-N15 WLAN Card User Manual26 ASUS WLAN CardEncryptionThis provides wireless data transmissions with a level of security. This option allows you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters. 64-bit and 40-bit WEP keys use the same encryption method and can interoperate on wireless networks. This lower level of WEP encryption uses a 40-bit (10 hexadecimal digits assigned by the user) secret key and a 24-bit Initialization Vector assigned by the device. 104-bit and 128-bit WEP keys use the same encryption method.All wireless clients in a network must have identical WEP keys with the access point to establish connection. Keep a record of the WEP encryption keys.Extended Service Set (ESS)A set of one or more interconnected basic service set (BSSs) and integrated local area networks (LANs) can be congured as an Extended Service Set.ESSID (Extended Service Set Identier)You must have the same ESSID entered into the gateway and each of its wireless clients. The ESSID is a unique identier for your wireless network.EthernetThe most widely used LAN access method, which is dened by the IEEE 802.3 standard. Ethernet is normally a shared media LAN meaning all devices on the network segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10-BaseT cables.FirewallA rewall determines which information passes in and out of a network. NAT can create a natural rewall by hiding a local network’s IP addresses from the Internet.

The rest of the computers can send and receive e-mail messages and access the web as if it were connected directly to the Internet.IEEEThe Institute of Electrical and Electronics Engineers. The IEEE sets standards for networking, including Ethernet LANs. IEEE standards ensure interoperability between systems of the same type.IEEE 802.11IEEE 802.xx is a set of specications for LANs from the Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specication for CSMA/CD based Ethernet networks or 802.5, the specication for token ring networks. 802.11 denes the standard for wireless LANs encompassing three incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. 802.11 species a carrier sense media access control and physical layer specications for 1 and 2 Mbps wireless LANs.IEEE 802.11a (54Mbits/sec)Compared with 802.11b: The 802.11b standard was designed to operate in the 2.4GHz ISM (Industrial, Scientic and Medical) band using direct-sequence spreadspectrum technology. The 802.11a standard, on the other hand, was designed to operate in the more recently allocated 5-GHz UNII (Unlicensed National Information Infrastructure) band. And unlike 802.11b, the 802.11a standard departs from the traditional spread-spectrum technology, instead using a frequency division multiplexing scheme that’s intended to be friendlier to ofce environments.The 802.11a standard, which supports data rates of up to 54 Mbps, is the Fast Ethernet analog to 802.11b, which supports data rates of up to 11 Mbps. Like Ethernet and Fast Ethernet, 802.11b and 802.11a use an identical MAC (Media Access Control). However, while Fast Ethernet uses the same physical-layer encoding scheme as Ethernet (only faster), 802.11a uses an entirely different encoding scheme, called OFDM (orthogonal frequency division multiplexing).The 802.11b spectrum is plagued by saturation from wireless phones, microwave ovens and other emerging wireless technologies, such as Bluetooth. In contrast, 802.11a spectrum is relatively free of interference.E6557_PCE-N15_Manual.indd 27 4/8/11 2:56:53 PM
PCE-N15 WLAN Card User Manual28 ASUS WLAN CardCompared with 802.11g: 802.11a is a standard for access points and radio NICs that is ahead of 802.11g in the market by about six months. 802.11a operates in the 5GHz frequency band with twelve separate non-overlapping channels. As a result, you can have up to twelve access points set to different channels in the same area without them interfering with each other. This makes access point channel assignment much easier and signicantly increases the throughput the wireless LAN can deliver within a given area. In addition, RF interference is much less likely because of the less-crowded 5GHz band.IEEE 802.11b (11Mbits/sec)In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 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 802.11 standard operate at a data rate of either 1 or 2 Mbps.In 1999, the IEEE created the 802.11b standard. 802.11b is essentially identical to the 802.11 standard except 802.11b provides for data rates of up to 11Mbps for direct sequence spread spectrum devices. Under 802.11b, direct sequence devices can operate at 11Mbps, 5.5Mbps, 2Mbps, or 1Mbps. This provides interoperability with existing 802.11 direct sequence devices that operate only at 2Mbps.Direct sequence spread spectrum devices spread a radio signal over a range of frequencies. The IEEE 802.11b specication allocates the 2.4GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies.IEEE 802.11g802.11g is a new extension to 802.11b (used in majority of wireless LANs today) that broadens 802.11b’s data rates to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division multiplexing) technology. 802.11g allows backward compatibility with 802.11b devices but only at 11 Mbps or lower, depending on the range and presence of obstructions. InfrastructureA wireless network centered about an access point. In this environment, the access point not only provides communication with the wired network but also mediates wireless network trafc in the immediate neighborhood.The 802.11a standard gains some of its performance from the higher frequencies at which it operates. The laws of information theory tie frequency, radiated power and distance together in an inverse relationship. Thus, moving up to the 5GHz spectrum from 2.4GHz will lead to shorter distances, given the same radiated power and encoding scheme.E6557_PCE-N15_Manual.indd 28 4/8/11 2:56:54 PM

The benets include the sharing of Internet access, les and equipment like printers and storage devices. Special network cabling (10 Base-T) is often used to connect the PCs together.MAC Address (Media Access Control)A MAC address is the hardware address of a device connected to a network. NAT (Network Address Translation)NAT masks a local network’s group of IP addresses from the external network, allowing a local network of computers to share a single ISP account. This process allows all of the computers on your home network to use one IP address. This will enable access to the Internet from any computer on your home network without having to purchase more IP addresses from your ISP.E6557_PCE-N15_Manual.indd 29 4/8/11 2:56:54 PM
