Wireless-G PCI AdapterInstant Wireless®Series

If the wireless network is relatively small and needs to share resources only

with the other computers on the wireless network, then the ad-hoc mode can

be 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 with

computers on a wired network. And, of course, communication between the

wireless-equipped computers is limited by the distance and interference direct-

ly between them.

Figure 2-2

Chapter 2:Planning Your

Wireless Network

A 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 to

connect to the network. Computers in a WLAN share the same frequency

channel and SSID, which is an identification name for wireless devices.

Unlike wired networks, wireless networks have two different modes in which

they may be set up: infrastructure and ad-hoc. In an infrastructure configu-

ration a WLAN and wired LAN communicate to each other through an access

point. In ad-hoc configuration, wireless-equipped computers communicate

directly with each other. Choosing between these two modes depends on

whether or not the wireless network needs to share data or peripherals with a

wired network or not.

If the computers on the

wireless network need to

be accessed by a wired

network or need to share a

peripheral, such as a print-

er, with the wired network

computers, the wireless

network should be set up

in infrastructure mode.

(See Figure 2-1.) The

basis of infrastructure

mode centers around an

access point, which serves

as the main point of communications between a wired and wireless network.

Access points transmit data to PCs equipped with wireless network adapters,

which can roam within a certain radial range of the access point. Multiple

access points can be arranged to work in succession to extend the roaming

range, and can be set up to communicate with your Ethernet (wired) hardware

as well.

Can I play computer games with other members of the wireless network?

Yes, as long as the game supports multiple players over a LAN (local area net-

work). Refer to the game’s user guide for more information.

What is the IEEE 802.11b standard?

It is one of the IEEE standards for wireless networks. The 802.11b standard

allows wireless networking hardware from different manufacturers to commu-

nicate, provided that the hardware complies with the 802.11b standard. The

802.11b standard states a maximum data transfer rate of 11Mbps and an oper-

ating frequency of 2.4GHz.

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-hoc

wireless network will not communicate with any wired network.

What is infrastructure mode?

When a wireless network is set to infrastructure mode, the wireless network is

configured to communicate with a wired network through a wireless access

point.

What is roaming?

Roaming is the ability of a portable computer user to communicate continu-

ously while moving freely throughout an area greater than that covered by a sin-

gle access point. Before using the roaming function, the workstation must make

sure that it is the same channel number with the access point of dedicated cov-

erage area.

To achieve true seamless connectivity, the wireless LAN must incorporate a

number of different functions. Each node and access point, for example, must

always acknowledge receipt of each message. Each node must maintain contact

with the wireless network even when not actually transmitting data. Achieving

these functions simultaneously requires a dynamic RF networking technology

that links access points and nodes. In such a system, the user’s end node under-

takes a search for the best possible access to the system. First, it evaluates such

factors as signal strength and quality, as well as the message load currently

being carried by each access point and the distance of each access point to the

wired backbone. Based on that information, the node next selects the right

access point and registers its address. Communications between end node and

host computer can then be transmitted up and down the backbone.

As the user moves on, the end node’s RF transmitter regularly checks the sys-

tem to determine whether it is in touch with the original access point or whether

it should seek a new one. When a node no longer receives acknowledgment

from its original access point, it undertakes a new search. Upon finding a new

access point, it then re-registers, and the communication process continues.

What is ISM band?

The FCC and their counterparts outside of the U.S. have set aside bandwidth

for unlicensed use in the ISM (Industrial, Scientific and Medical) band.

Spectrum in the vicinity of 2.4 GHz, in particular, is being made available

worldwide. This presents a truly revolutionary opportunity to place convenient

high-speed wireless capabilities in the hands of users around the globe.

What 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 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).

What is DSSS? What is FHSS? And what are their differences?

Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that

changes frequency in a pattern that is known to both transmitter and receiver.

Properly synchronized, the net effect is to maintain a single logical channel. To

Appendix B:Glossary

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 standard

specifies a maximum data transfer rate of 11Mbps, an operating frequency of

2.4GHz, and WEP encryption for security. 802.11b networks are also referred

to 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 used

by Linksys specify a maximum data transfer rate of 54Mbps using OFDM

modulation, an operating frequency of 2.4GHz, backward compatibility with

IEEE 802.11b devices, and WEP encryption for security.

Adapter - Printed circuit board that plugs into a PC to add to capabilities or

connectivity to a PC. In a networked environment, a network interface card is

the typical adapter that allows the PC or server to connect to the intranet and/or

Internet.

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.

Backbone - The part of a network that connects most of the systems and net-

works together and handles the most data.

Bandwidth - The transmission capacity of a given facility, in terms of how

much data the facility can transmit in a fixed amount of time; expressed in bits

per second (bps).

Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.

Also, the smallest form of data.

BSS (Basic Service Set) - An infrastructure network connecting wireless

devices to a wired network using a single access point.

Instant Wireless®Series

an unintended receiver, FHSS appears to be short-duration impulse noise.

Direct-Sequence Spread-Spectrum (DSSS) generates a redundant bit pattern

for each bit to be transmitted. This bit pattern is called a chip (or chipping

code). The longer the chip, the greater the probability that the original data can

be recovered. Even if one or more bits in the chip are damaged during trans-

mission, statistical techniques embedded in the radio 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 nar-

rowband receivers.

Would the information be intercepted while transmitting on air?

WLAN features two-fold protection in security. On the hardware side, as with

Direct 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.

What is WEP?

WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit

or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.

Wireless-G PCI Adapter

Instant Wireless®Series

Driver - A workstation or server software module that provides an interface

between a network interface card and the upper-layer protocol software running

in the computer; it is designed for a specific card, and is installed during the

initial installation of a network-compatible client or server operating system.

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 end-

point), the DSSS signal is recognized as the only valid signal, and interference

is inherently rejected (ignored).

Encryption - A security method that applies a specific algorithm to data in

order to alter the data's appearance and prevent other devices from reading the

information.

Ethernet - IEEE standard network protocol that specifies how data is placed

on and retrieved from a common transmission medium. Has a transfer rate of

10 Mbps. Forms the underlying transport vehicle used by several upper-level

protocols, including TCP/IP and XNS.

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.

Fragmentation - Breaking a packet into smaller units when transmitting over

a network medium that cannot support the original size of the packet.

Gateway - A device that interconnects networks with different, incompatible

communications 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 computer

from the program you put in it to make it do things. The program came to be

known as the software.

CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) - In local

area networking, this is the CSMA technique that combines slotted time-divi-

sion multiplexing with carrier sense multiple access/collision detection

(CSMA/CD) to avoid having collisions occur a second time. This works best if

the time allocated is short compared to packet length and if the number of sit-

uations is small.

CTS (Clear To Send) - An RS-232 signal sent from the receiving station to the

transmitting station that indicates it is ready to accept data.

Default Gateway - The routing device used to forward all traffic that is not

addressed to a station within the local subnet.

DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network

administrators manage centrally and automate the assignment of Internet

Protocol (IP) addresses in an organization's network. Using the Internet's set of

protocol (TCP/IP), each machine that can connect to the Internet needs a

unique 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 IP

address must be entered. DHCP lets a network administrator supervise and dis-

tribute IP addresses from a central point and automatically sends a new IP

address 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 address

will be valid for a computer. The lease time can vary depending on how long a

user 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 networks

in which there are more computers than there are available IP addresses.

DHCP supports static addresses for computers containing Web servers that

need a permanent IP address.

DNS - The domain name system (DNS) is the way that Internet domain name

are located and translated into Internet Protocol (IP) addresses. A domain name

is a meaningful and easy-to-remember "handle" for an Internet address.

Domain - A subnetwork comprised of a group of clients and servers under the

control of one security database. Dividing LANs into domains improves per-

formance and security.

ISM band - The FCC and their counterparts outside of the U.S. have set aside

bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical)

band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made avail-

able worldwide. This presents a truly revolutionary opportunity to place con-

venient high-speed wireless capabilities in the hands of users around the globe.

LAN (Local Area Network) - A group of computers and associated devices that

share a common communications line and typically share the resources of a

single processor or server within a small geographic area (for example, within

an office building).

MAC (Media Access Control) Address - A unique number assigned by the

manufacturer to any Ethernet networking device, such as a network adapter,

that allows the network to identify it at the hardware level.

Mbps (Megabits per second) - One million bits per second; unit of measure-

ment for data transmission.

Motherboard - A motherboard is the physical arrangement in a computer that

contains the computer's basic circuitry and components.

Network - A system that transmits any combination of voice, video and/or data

between users.

Node - A network junction or connection point, typically a computer or work

station.

OFDM - Developed for wireless applications, Orthogonal Frequency Division

Multiplexing (OFDM) technology offers superior performance-increased data

rates and more reliable transmissions-than previous technologies, such as

DSSS. OFDM is a scheme in which numerous signals of different frequencies

are 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 speed

stream is used to modulate a subcarrier. Essentially, this creates a multi-carrier

transmission by dividing a wide frequency band or channel into a number of

narrower frequency bands or sub-channels. OFDM is also used for other appli-

cations, including powerline networking.

Packet - A unit of data routed between an origin and a destination in a network.

Hop - The link between two network nodes.

IEEE (The Institute of Electrical and Electronics Engineers) - The IEEE

describes itself as "the world's largest technical professional society, promoting

the development and application of electrotechnology and allied sciences for

the benefit of humanity, the advancement of the profession, and the well-being

of our members."

The IEEE fosters the development of standards that often become national and

international standards. The organization publishes a number of journals, has

many local chapters, and several large societies in special areas, such as the

IEEE Computer Society.

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. In infrastructure mode, the wireless devices communicate with each

other 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 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.

IP (Internet Protocol) - The method or protocol by which data is sent from one

computer to another on the Internet. It is a standard set of rules, procedures, or

conventions relating to the format and timing of data transmission between two

computers 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 or

receiver of information that is sent in packet across the Internet. When you

request an HTML page or send e-mail, the Internet Protocol part of TCP/IP

includes your IP address in the message (actually, in each of the packets if more

than one is required) and sends it to the IP address that is obtained by looking

up the domain name in the Uniform Resource Locator you requested or in the

e-mail address you're sending a note to. At the other end, the recipient can see

the IP address of the Web page requestor or the e-mail sender and can respond

by sending another message using the IP address it received.

IRQ (Interrupt ReQuest) - A hardware interrupt on a PC. There are 16 IRQ

lines used to signal the CPU that a peripheral event has started or terminated.

Except for PCI devices, two devices cannot use the same line.

Wireless-G PCI Adapter

Server - Any computer whose function in a network is to provide user access

to files, printing, communications, and other services.

Software - Instructions for the computer. A series of instructions that performs

a particular task is called a "program." The two major categories of software are

"system software" and "application software." System software is made up of

control programs such as the operating system and database management sys-

tem (DBMS). Application software is any program that processes data for the

user.

A common misconception is that software is data. It is not. Software tells the

hardware how to process the data.

SOHO (Small Office/Home Office) - Market segment of professionals who

work at home or in small offices.

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 efficiency

for reliability, integrity, and security. In other words, more bandwidth is con-

sumed 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).

SSID (Service Set IDentifier) - A unique name shared among all points in a

wireless network. The SSID must be identical for each point in the wireless net-

work and is case-sensitive.

Storage - The semi-permanent or permanent holding place for digital data.

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 IP

address to turn part of the host ID address field into a field for subnets.

Switch - 1. A data switch connects computing devices to host computers,

allowing a large number of devices to share a limited number of ports. 2. A

device for making, breaking, or changing the connections in an electrical cir-

cuit.

Instant Wireless®Series

Passphrase - Used much like a password, a passphrase simplifies the WEP

encryption process by automatically generating the WEP encryption keys for

Linksys products.

PCI (Peripheral Component Interconnect) - A peripheral bus commonly used

in PCs, Macintoshes and workstations. It was designed primarily by Intel and

first appeared on PCs in late 1993. PCI provides a high-speed data path

between the CPU and peripheral devices (video, disk, network, etc.). There are

typically three or four PCI slots on the motherboard. In a Pentium PC, there is

generally a mix of PCI and ISA slots or PCI and EISA slots. Early on, the PCI

bus was known as a "local bus."

PCI provides "plug and play" capability, automatically configuring the PCI

cards 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 in

use by ISA cards. PCI takes care of the rest.

PCI allows IRQs to be shared, which helps to solve the problem of limited IRQs

available on a PC. For example, if there were only one IRQ left over after ISA

devices 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 expansion

boards and other devices automatically without requiring the user to turn off

the system during installation.

Port - A pathway into and out of the computer or a network device such as a

switch or router. For example, the serial and parallel ports on a personal com-

puter are external sockets for plugging in communications lines, modems and

printers.

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 transparently

reassociate and reauthenticate to the new access point. This reassociation and

reauthentication should occur without user intervention and ideally without

interruption to network connectivity. A typical scenario would be a location

with multiple access points, where users can physically relocate from one area

to another and easily maintain connectivity.

RTS (Request To Send) - An RS-232 signal sent from the transmitting station

to the receiving station requesting permission to transmit.

TCP (Transmission Control 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 handling

the actual delivery of the data (routing), TCP takes care of keeping track of the

individual 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 of

receipt 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 of

protocols and not only TCP and IP.

Throughput - The amount of data moved successfully from one place to

another in a given time period.

Topology - A network's topology is a logical characterization of how the

devices on the network are connected and the distances between them. The

most 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-area

connections.

WAN (Wide Area Network)- A communications network that covers a rela-

tively large geographic area, consisting of two or more LANs. Broadband com-

munication over the WAN is often through public networks such as the tele-

phone (DSL) or cable systems, or through leased lines or satellites. In its most

basic definition, the Internet could be considered a WAN.

WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-

bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.

WLAN (Wireless Local Area Network) - A group of computers and associat-

ed devices that communicate with each other wirelessly.
