Dual-Band Wireless A+G PCI AdapterInstant Wireless®SeriesIf the wireless network is relatively small and needs to share resources onlywith the other computers on the wireless network, then the ad-hoc mode canbe used. (See Figure 2-2.) Ad-hoc mode allows computers equipped with wire-less transmitters and receivers to communicate directly with each other, elimi-nating the need for an access point. The drawback of this mode is that, in Ad-Hoc mode, wireless-equipped computers are not able to communicate withcomputers on a wired network. And, of course, communication between thewireless-equipped computers is limited by the distance and interference direct-ly between them.32Figure 2-2Chapter 2: Planning Your WirelessNetworkA wireless local area network (WLAN) is exactly like a regular local area net-work (LAN), except that each computer in the WLAN uses a wireless device toconnect to the network. Computers in a WLAN share the same frequency chan-nel and SSID, which is an identification name for wireless devices.Unlike wired networks, wireless networks have two different modes in whichthey may be set up: infrastructure and ad-hoc. An infrastructure configura-tion is a WLAN and wired LAN communicating to each other through anaccess point. An ad-hoc configuration is wireless-equipped computers com-municating directly with each other. Choosing between these two modesdepends on whether or not the wireless network needs to share data or periph-erals with a wired network or not.If the computers on thewireless network need tobe accessed by a wirednetwork or need to share aperipheral, such as a print-er, with the wired networkcomputers, the wirelessnetwork should be set upin infrastructure mode.(See Figure 2-1.) Thebasis of infrastructuremode centers around anaccess point, which servesas the main point of communications in a wireless network. Access pointstransmit data to PCs equipped with wireless network cards, which can roamwithin a certain radial range of the access point. Multiple access points can bearranged to work in succession to extend the roaming range, and can be set upto communicate with your Ethernet (wired) hardware as well.

Dual-Band Wireless A+G PCI Adapter31Instant Wireless®Series30What is Spread Spectrum?Spread Spectrum technology is a wideband radio frequency technique devel-oped by the military for use in reliable, secure, mission-critical communica-tions systems. It is designed to trade off bandwidth efficiency for reliability,integrity, and security. In other words, more bandwidth is consumed than in thecase of narrowband transmission, but the trade-off produces a signal that is, ineffect, louder and thus easier to detect, provided that the receiver knows theparameters of the spread-spectrum signal being broadcast. If a receiver is nottuned to the right frequency, a spread-spectrum signal looks like backgroundnoise. There are two main alternatives, Direct Sequence Spread Spectrum(DSSS) and Frequency Hopping Spread Spectrum (FHSS).What is DSSS? What is FHSS? And what are their differences?Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier thatchanges frequency in a pattern that is known to both transmitter and receiver.Properly synchronized, the net effect is to maintain a single logical channel. Toan unintended receiver, FHSS appears to be short-duration impulse noise.Direct-Sequence Spread-Spectrum (DSSS) generates a redundant bit patternfor each bit to be transmitted. This bit pattern is called a chip (or chippingcode). The longer the chip, the greater the probability that the original data canbe recovered. Even if one or more bits in the chip are damaged during trans-mission, statistical techniques embedded in the radio can recover the originaldata without the need for retransmission. To an unintended receiver, DSSSappears as low power wideband noise and is rejected (ignored) by most nar-rowband receivers. Would the information be intercepted while transmitting on air?WLAN features two-fold protection in security. On the hardware side, as withDirect Sequence Spread Spectrum technology, it has the inherent security fea-ture of scrambling. On the software side, WLAN offers the encryption function(WEP) to enhance security and access control.Can Instant Wireless products support printer sharing?Instant Wireless products perform the same function as LAN products.Therefore, Instant Wireless products can work with NetWare, WindowsNT/2000, or other network operating systems to support printer or file sharing.What is WEP?WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40/64bit shared key algorithm, as described in the IEEE 802.11 standard. 802.11a standard states a maximum data transfer rate of 54Mbps and an oper-ating frequency of 5GHz.What is the IEEE 802.11b standard?It is one of the IEEE standards for wireless networks. The 802.11b standardallows wireless networking hardware from different manufacturers to commu-nicate, provided that the hardware complies with the 802.11b standard. The802.11b standard states a maximum data transfer rate of 11Mbps and an oper-ating frequency of 2.4GHz.What IEEE 802.11a features are supported?The product supports the following IEEE 802.11a functions: • OFDM protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation What IEEE 802.11b features are supported?The product supports the following IEEE 802.11b functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What is ad-hoc mode?When a wireless network is set to ad-hoc mode, the wireless-equipped com-puters are configured to communicate directly with each other. The ad-hocwireless network will not communicate with any wired network. What is infrastructure mode?When a wireless network is set to infrastructure mode, the wireless network isconfigured to communicate with a wired network through a wireless accesspoint.What is ISM band?The FCC and their counterparts outside of the U.S. have set aside bandwidthfor unlicensed use in the ISM (Industrial, Scientific and Medical) band.Spectrum in the vicinity of 2.4 GHz, in particular, is being made availableworldwide. This presents a truly revolutionary opportunity to place convenienthigh-speed wireless capabilities in the hands of users around the globe.
Dual-Band Wireless A+G PCI Adapter33Instant Wireless®Series32on startup. These instructions search for the operating system, load it and passcontrol to it. CTS (Clear To Send) - An RS-232 signal sent from the receiving station to thetransmitting station that indicates it is ready to accept data.Default Gateway - The router used to forward all traffic that is not addressedto a station within the local subnet.DHCP (Dynamic Host Configuration Protocol) - A protocol that lets networkadministrators manage centrally and automate the assignment of InternetProtocol (IP) addresses in an organization’s network. Using the Internet’s set ofprotocol (TCP/IP), each machine that can connect to the Internet needs aunique IP address. When an organization sets up its computer users with a con-nection to the Internet, an IP address must be assigned to each machine.Without DHCP, the IP address must be entered manually at each computer and,if computers move to another location in another part of the network, a new IPaddress must be entered. DHCP lets a network administrator supervise and dis-tribute IP addresses from a central point and automatically sends a new IPaddress when a computer is plugged into a different place in the network. DHCP uses the concept of a “lease” or amount of time that a given IP addresswill be valid for a computer. The lease time can vary depending on how long auser is likely to require the Internet connection at a particular location. It’s espe-cially useful in education and other environments where users change fre-quently. Using very short leases, DHCP can dynamically reconfigure networksin which there are more computers than there are available IP addresses. DHCP supports static addresses for computers containing Web servers thatneed a permanent IP address. DNS - The domain name system (DNS) is the way that Internet domain nameare located and translated into Internet Protocol (IP) addresses. A domain nameis a meaningful and easy-to-remember “handle” for an Internet address. Driver - A workstation or server software module that provides an interfacebetween a network interface card and the upper-layer protocol software runningin the computer; it is designed for a specific NIC, and is installed during theinitial installation of a network-compatible client or server operating system.DSSS (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bitpattern for all transmitted data. This bit pattern is called a chip (or chippingAppendix B: Glossary802.11a - One of the IEEE standards for wireless networking hardware.Products that adhere to a specific IEEE standard will work with each other,even if they are manufactured by different companies. It specifies a maximumdata transfer rate of 54Mbps and an operating frequency of 5GHz. The 802.11astandard uses the Orthogonal Frequency Division Multiplexing (OFDM) trans-mission method. Additionally, the 802.11a standard supports 802.11 featuressuch as WEP encryption for security.802.11b - One of the IEEE standards for wireless networking hardware.Products that adhere to a specific IEEE standard will work with each other,even if they are manufactured by different companies. The 802.11b standardspecifies a maximum data transfer rate of 11Mbps, an operating frequency of2.4GHz, and WEP encryption for security. 802.11b networks are also referredto as Wi-Fi networks.802.11g - A proposed, but as yet unratified extension of the IEEE 802.11 stan-dard for wireless networking hardware. The draft 802.11g specifications usedby Linksys specify a maximum data transfer rate of 54Mbps using OFDMmodulation, an operating frequency of 2.4GHz, backward compatibility withIEEE 802.11b devices, and WEP encryption for security.Adapter - Printed circuit board that plugs into a PC to add to capabilities orconnectivity to a PC. In a networked environment, a network interface card(NIC) is the typical adapter that allows the PC or server to connect to theintranet and/or Internet.Ad-hoc Network - An ad-hoc network is a group of computers, each with awireless adapter, connected as an independent 802.11 wireless LAN. Ad-hocwireless computers operate on a peer-to-peer basis, communicating directlywith each other without the use of an access point. Ad-hoc mode is alsoreferred to as an Independent Basic Service Set (IBSS) or as peer-to-peermode, and is useful at a departmental scale or SOHO operation.Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.Also, the smallest form of data.Boot - To cause the computer to start executing instructions. Personal comput-ers contain built-in instructions in a ROM chip that are automatically executed
Dual-Band Wireless A+G PCI Adapter35Instant Wireless®Series34The IEEE fosters the development of standards that often become national andinternational standards. The organization publishes a number of journals, hasmany local chapters, and several large societies in special areas, such as theIEEE Computer Society. Infrastructure Network - An infrastructure network is a group of computersor other devices, each with a wireless adapter, connected as an 802.11 wirelessLAN. In infrastructure mode, the wireless devices communicate with eachother and to a wired network by first going through an access point. An infra-structure wireless network connected to a wired network is referred to as aBasic Service Set (BSS). A set of two or more BSS in a single network isreferred to as an Extended Service Set (ESS). Infrastructure mode is useful ata corporation scale, or when it is necessary to connect the wired and wirelessnetworks.IP (Internet Protocol) - The method or protocol by which data is sent from onecomputer to another on the Internet. It is a standard set of rules, procedures, orconventions relating to the format and timing of data transmission between twocomputers that they must accept and use to be able to understand each other.IP Address - In the most widely installed level of the Internet Protocol (IP)today, an IP address is a 32-binary digit number that identifies each sender orreceiver of information that is sent in packet across the Internet. When yourequest an HTML page or send e-mail, the Internet Protocol part of TCP/IPincludes your IP address in the message (actually, in each of the packets if morethan one is required) and sends it to the IP address that is obtained by lookingup the domain name in the Uniform Resource Locator you requested or in thee-mail address you're sending a note to. At the other end, the recipient can seethe IP address of the Web page requester or the e-mail sender and can respondby sending another message using the IP address it received. IPCONFIG - A utility that provides for querying, defining and managing IPaddresses within a network. A commonly used utility, under Windows NT and2000, for configuring networks with static IP addresses.ISP - An ISP (Internet service provider) is a company that provides individualsand companies access to the Internet and other related services such as Web sitebuilding and virtual hosting. LAN - A local area network (LAN) is a group of computers and associateddevices that share a common communications line and typically share thecode). Even if one or more bits in the chip are damaged during transmission,statistical techniques embedded in the receiver can recover the original datawithout the need for retransmission. To an unintended receiver, DSSS appearsas low power wideband noise and is rejected (ignored) by most narrowbandreceivers. However, to an intended receiver (i.e., another wireless LAN end-point), the DSSS signal is recognized as the only valid signal, and interferenceis inherently rejected (ignored).Dynamic IP Address - An IP address that is automatically assigned to a clientstation in a TCP/IP network, typically by a DHCP server. Network devices thatserve multiple users, such as servers and printers, are usually assigned static IPaddresses. Encryption - A security method that applies a specific algorithm to data inorder to alter the data's appearance and prevent other devices from reading theinformation. FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes(hops) the carrier frequency of a conventional carrier several times per secondaccording to a pseudo-random set of channels. Because a fixed frequency is notused, and only the transmitter and receiver know the hop patterns, interceptionof FHSS is extremely difficult.Firmware - Code that is written onto read-only memory (ROM) or program-mable read-only memory (PROM). Once firmware has been written onto theROM or PROM, it is retained even when the device is turned off.Gateway - A device that interconnects networks with different, incompatiblecommunications protocols. Hardware - Hardware is the physical aspect of computers, telecommunica-tions, and other information technology devices. The term arose as a way to dis-tinguish the “box” and the electronic circuitry and components of a computerfrom the program you put in it to make it do things. The program came to beknown as the software.IEEE - The Institute of Electrical and Electronics Engineers. The IEEEdescribes itself as “the world’s largest technical professional society—promot-ing the development and application of electrotechnology and allied sciencesfor the benefit of humanity, the advancement of the profession, and the well-being of our members.”
Dual-Band Wireless A+G PCI Adapter37Instant Wireless®Series36PCI (Peripheral Component Interconnect) - A peripheral bus commonly usedin PCs, Macintoshes and workstations. It was designed primarily by Intel andfirst appeared on PCs in late 1993. PCI provides a high-speed data pathbetween the CPU and peripheral devices (video, disk, network, etc.). There aretypically three or four PCI slots on the motherboard. In a Pentium PC, there isgenerally a mix of PCI and ISA slots or PCI and EISA slots. Early on, the PCIbus was known as a “local bus.”PCI provides “plug and play” capability, automatically configuring the PCIcards at startup. When PCI is used with the ISA bus, the only thing that is gen-erally required is to indicate in the CMOS memory which IRQs are already inuse by ISA cards. PCI takes care of the rest.PCI allows IRQs to be shared, which helps to solve the problem of limited IRQsavailable on a PC. For example, if there were only one IRQ left over after ISAdevices were given their required IRQs, all PCI devices could share it. In a PCI-only machine, there cannot be insufficient IRQs, as all can be shared.Plug-and-Play - The ability of a computer system to configure expansionboards and other devices automatically without requiring the user to turn offthe system during installation.Roaming - In an infrastructure mode wireless network, this refers to the abili-ty to move out of one access point's range and into another and transparentlyreassociate and reauthenticate to the new access point. This reassociation andreauthentication should occur without user intervention and ideally withoutinterruption to network connectivity. A typical scenario would be a locationwith multiple access points, where users can physically relocate from one areato another and easily maintain connectivity.Spread Spectrum - Spread Spectrum technology is a wideband radio frequen-cy technique developed by the military for use in reliable, secure, mission-crit-ical communications systems. It is designed to trade off bandwidth efficiencyfor reliability, integrity, and security. In other words, more bandwidth is con-sumed than in the case of narrowband transmission, but the trade off producesa signal that is, in effect, louder and thus easier to detect, provided that thereceiver knows the parameters of the spread-spectrum signal being broadcast.If a receiver is not tuned to the right frequency, a spread-spectrum signal lookslike background noise. There are two main alternatives, Direct SequenceSpread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).resources of a single processor or server within a small geographic area (forexample, within an office building). MAC Address - The MAC (Media Access Control) address is your computer’sunique hardware number. Mbps (Megabits per second) - One million bits per second; unit of measure-ment for data transmission.mIRC - mIRC runs under Windows and provides a graphical interface for log-ging onto IRC servers and listing, joining and leaving channels.Motherboard - A motherboard is the physical arrangement in a computer thatcontains the computer's basic circuitry and components. Network - A system that transmits any combination of voice, video and/or databetween users. Network Mask - also known as the “Subnet Mask.”NIC (Network Interface Card) - A board installed in a computer system, usu-ally a PC, to provide network communication capabilities to and from that com-puter system. Also called an adapter.OFDM - Developed for wireless applications, Orthogonal Frequency DivisionMultiplexing (OFDM) technology offers superior performance-increased datarates and more reliable transmissions-than previous technologies, such asDSSS. OFDM is a scheme in which numerous signals of different frequenciesare combined to form a single signal for transmission on the medium. OFDM works by breaking one high-speed data stream into a number of lower-speed data streams, which are then transmitted in parallel. Each lower speedstream is used to modulate a subcarrier. Essentially, this creates a multi-carriertransmission by dividing a wide frequency band or channel into a number ofnarrower frequency bands or sub-channels. OFDM is also used for other appli-cations, including powerline networking.Passphrase - Used much like a password, a passphrase simplifies the WEPencryption process by automatically generating the WEP encryption keys forLinksys products.
Dual-Band Wireless A+G PCI AdapterWEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit shared key algorithm, as described in the IEEE 802.11b standard. WINIPCFG - Configuration utility based on the Win32 API for querying,defining and managing IP addresses within a network. A commonly used util-ity under Windows 95, 98, and Me.WLAN (Wireless Local Area Network) - A group of computers and associat-ed devices that communicate with each other wirelessly.39Instant Wireless®Series38SSID (Service Set IDentifier) - A unique name shared among all points in awireless network. The SSID must be identical for each point in the wireless net-work and is case-sensitive. Static IP Address - A permanent IP address that is assigned to a node in aTCP/IP network. Subnet Mask - The method used for splitting IP networks into a series of sub-groups, or subnets. The mask is a binary pattern that is matched up with the IPaddress to turn part of the host ID address field into a field for subnets. TCP (Transmission Control Protocol) - A method (protocol) used along withthe IP (Internet Protocol) to send data in the form of message units (datagram)between network devices over a LAN or WAN. While IP takes care of handlingthe actual delivery of the data (routing), TCP takes care of keeping track of theindividual units of data (called packets) that a message is divided into for effi-cient delivery over the network. TCP is known as a “connection oriented” pro-tocol due to requiring the receiver of a packet to return an acknowledgment ofreceipt to the sender of the packet resulting in transmission control.TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com-munication language or set of protocols for communications over a network(developed specifically for the Internet). TCP/IP defines a suite or group ofprotocols and not only TCP and IP.Topology - A network's topology is a logical characterization of how thedevices on the network are connected and the distances between them. Themost common network devices include hubs, switches, routers, and gateways.Most large networks contain several levels of interconnection, the most impor-tant of which include edge connections, backbone connections, and wide-areaconnections.UDP (User Datagram Protocol) - A method (protocol) used along with the IP(Internet Protocol) to send data in the form of message units (datagram)between network devices over a LAN or WAN. While IP takes care of handlingthe actual delivery of the data (routing), UDP takes care of keeping track of theindividual units of data (called packets) that a message is divided into for effi-cient delivery over the network. UDP is known as a “connection-less” protocoldue to NOT requiring the receiver of a packet to return an acknowledgment ofreceipt to the sender of the packet (as opposed to TCP).
