The Instant Wireless Network Access Point

Wireless Network Access Point

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.

Instant Wireless

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. An infrastructure configura-

tion is a WLAN and wired LAN communicating to each other through an

access point. An ad-hoc configuration is wireless-equipped computers com-

municating directly with each other. Choosing between these two modes

depends on whether or not the wireless network needs to share data or periph-

erals 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 com-

munications in a wireless network. Access points transmit data to PCs equipped

with wireless network cards, 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.

The Access Point’s ports, where a network cable is connected, are located on

the Access Point’s rear panel.

Dipole Antenna

Connectors These two round connections are where the antennas are

connected to the Access Point.

LAN This LAN (Local Area Network) port connects to

Ethernet network devices, such as a hub, switch, or

router.

Power The Power port is where you will connect the power

adapter.

Reset Button There are two ways to reset the Access Point’s factory

defaults. Briefly press the Reset Button for approximately

ten seconds, or use the Password tab of the Access Point’s

Power Red. The Power LED lights up when the Access Point is

powered on.

ACT Green. If the LED is flickering, the Access Point is actively

sending or receiving data to or from one of the devices on the

wireless network.

LINK Orange. The LINK LED serves two purposes. If the LED is

continuously lit up, the Access Point is successfully connect-

ed to a device through the LAN port. If the LED is flicker-

ing, it is an indication of any wired network activity.

Chapter 5: Setting Up the

Wireless Network Access Point

Now that you’ve connected the Access Point to your wired network, you are

ready to begin setting it up. This Setup Wizard will take you through all the

steps necessary to get the Access Point connecting your wireless network to

your wired network and communicating more efficiently.

1. Insert the Setup Wizard CD into your PC’s CD-ROM drive. Optimally, your

PC should be on your wired network.

2. The screen in Figure 5-1 should appear on your monitor. If it does not, this

means the autorun is not functioning. Start the autorun manually by click-

ing the Start button, selecting Run, and typing D:\setup.exe (if “D” is your

PC’s CD-ROM drive). Click the Setup button to run the Setup Wizard.

Clicking the User Guide button opened this User Guide. To access the

Chapter 4: Connecting the

Wireless Network Access Point

1. Locate an optimum location for the Access Point. The best place for the

Access Point is usually at the center of your wireless network, with line of

sight to all of your mobile stations.

2. Fix the direction of the antenna. Try to place it in a position which can best

cover your wireless network. Normally, the higher you place the antenna,

the better the performance will be. The antenna’s position enhances the

receiving sensitivity. Both antennas should be perpendicular to the ground

and parallel to each other.

3. Connect the included Category 5 Ethernet network cable to the Access

Point. Then, connect the other end of the Ethernet cable to a switch or hub.

The Access Point will then be connected to your 10/100 network.

4. Connect the AC power adapter to the Access Point’s Power port. Only use

the power adapter supplied with the Access Point. Use of a different adapter

may result in product damage.

Now that the hardware installation is complete, proceed to “Chapter 5: Setting

Up the Wireless Network Access Point” for directions on how to set up the

Access Point.

Have You: Connected the Access Point to a hub, switch, or router

on your wired network as shown in “Chapter 4: Connecting the

Wireless Network Access Point”?

Note: While the Access Point has been designed to work correctly

right out of the box, setting it up on a wireless computer will

require you to use the Linksys default settings. These settings can

then be changed through the Web-based Utility.

Note: In order for all other wireless devices to communicate with

the Access Point, those devices must be operating in the infrastruc-

ture mode. If any wireless devices are configured in the ad-hoc

mode, they will not be recognized by the Access Point.

Before making any changes to the Wireless tab, shown in Figure 6-12, please

check your wireless settings on your other systems, as these changes will alter

the effectiveness of the Access Point. In most cases, these wireless settings do

not need to be changed.

• Beacon Interval. This value indicates the frequency interval of the beacon.

A beacon is a packet broadcast by the Access Point to keep the network syn-

chronized. A beacon includes the wireless LAN service area, the AP

address, the Broadcast destination addresses, a time stamp, Delivery Traffic

Indicator Maps, and the Traffic Indicator Message (TIM).

• RTS Threshold. This value should remain at its default setting of 2346.

Should you encounter inconsistent data flow, only minor reductions are rec-

ommended.

• Fragmentation Threshold. This value specifies the maximum size for a

packet before data is fragmented into multiple packets. It should remain at

its default setting of 2346. A smaller setting means smaller packets, which

will create more packets for each transmission. Only minor reductions of

this value are recommended.

• DTIM Interval. This value indicates the interval of the Delivery Traffic

Indication Message (DTIM). A DTIM field is a countdown field informing

clients of the next window for listening to broadcast and multicast mes-

sages. When the Access Point has buffered broadcast or multicast messages

for associated clients, it sends the next DTIM with a DTIM Interval value.

Access Point Clients hear the beacons and awaken to receive the broadcast

and multicast messages.

• Basic Rates. The basic rate is the minimum speed at which a wireless client

is allowed to connect to the Access Point.

• Transmission Rates.The transmission rates should be set depending on the

speed of your wireless network. You must select 1-2 (Mbps) if you have

older 802.11 compliant equipment on your network, such as wireless

adapters that support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however,

does NOT limit the transmission rates of faster adapters.

• Preamble Type. The preamble defines the length of the CRC block for

communication between the Access Point and a roaming wireless network

adapter. (High network traffic areas should use the shorter preamble type.)

Select the appropriate preamble type and click the Apply button to set it.

All wireless points (nodes) on your network should use the same preamble

type.

• Authentication Type. You may choose between Open System, Shared

Key, and Both. The Authentication Type default is set to Open System.

Shared Key is when both the sender and the recipient share a secret key. All

points on your network must use the same authentication type. It is recom-

mended that you use the default setting.

• Antenna Selection. This selection is for choosing which antenna transmits

data. By default, the Diversity Antenna selection, used to increase recep-

tion, is chosen.

Appendix A: Troubleshooting

This chapter provides a list of questions and answers regarding the operation of

the Access Point. Read the description below to solve your problems. If you

can’t find an answer here, check the Linksys website at www.linksys.com.

Can the Access Point act as my DHCP Server?

No. The Access Point is nothing more than a wireless hub, and as such, cannot

be configured to handle DHCP capabilities.

Can I run an application from a remote computer over the wireless network?

This will depend on whether or not the application is designed to be used over

a network. Consult the application’s user guide to determine if it supports oper-

ation over a network.

Can I play multiplayer games with other users 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 802.11 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.

Frequently Asked Questions

Important: The Access Point will not be recognized by “site-sur-

vey” utilities, such as the Microsoft®Windows®XP Zero

Configuration Utility, if SSID Broadcast is disabled.

Wireless Network Access Point

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

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 transmis-

sion, 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 narrowband

receivers.

Would the information be intercepted while transmitting on air?

Instant Wireless products feature two-fold protection in security. On the hard-

ware side, as with Direct Sequence Spread Spectrum technology, it has the

inherent security feature of scrambling. On the software side, Instant Wireless

products offer the encryption function (WEP) to enhance security and access

control. Users can set it up depending upon their needs.

Can Instant Wireless products support file and printer sharing?

Instant Wireless products perform the same function as LAN products.

Therefore, Instant Wireless products can work with NetWare, Windows

NT/2000, or other LAN operating systems to support printer or file sharing.

What is WEP?

WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40/64

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

Instant Wireless

Series

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

single wireless network access point. Before using the roaming function, the

workstation must make sure that it is the same channel number as the wireless

network access point of the dedicated coverage area.

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

number of different functions. Each node and wireless network access point,

for example, must always acknowledge receipt of each message. Each node

must maintain contact with the wireless network even when not actually trans-

mitting data. Achieving these functions simultaneously requires a dynamic RF

networking technology that links wireless network access points and nodes. In

such a system, the user’s end node undertakes a search for the best possible

access to the system. First, it evaluates such factors as signal strength and qual-

ity, as well as the message load currently being carried by each wireless net-

work access point and the distance of each wireless network access point to the

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

wireless network 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 wireless network

access point or whether it should seek a new one. When a node no longer

receives acknowledgment from its original wireless network access point, it

undertakes a new search. Upon finding a new wireless network 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.

Wireless Network Access Point

Instant Wireless

Series

What is a MAC Address?

The Media Access Control (MAC) address is 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. For all practical pur-

poses, this number is usually permanent. Unlike IP addresses, which can

change every time a computer logs on to the network, the MAC address of a

device stays the same, making it a valuable identifier for the network.

Appendix B: Setting Up the TCP/IP

Protocol

Before a computer can communicate with the Access Point, it must be config-

ured with the TCP/IP protocol. If you know how to set up TCP/IP on your com-

puters, do so now. Otherwise, use the guidelines below to help get TCP/IP

installed on all of the computers that need to communicate with the Access

Point. If you are unable to successfully install TCP/IP on one or more comput-

ers after following the directions, contact the manufacturer of your computer’s

network operating system for further assistance. Check with your network

administrator for your TCP/IP settings.

The directions below provide general guidelines for coming up with IP address-

es and subnet masks. Check with your network administrator to see if you need

to use specific IP addresses or DHCP settings.

First, each computer on the network will require an IP address, which is a series

of numbers, separated by periods, identifying the PC on the network. To make

things simple, it is recommended you use the following numbering scheme:

192.168.1.X

In this example, X is a unique, arbitrarily assigned number from 1 to 254. Each

computer must have its own unique X number. Note: Never use 0 or 255 for X.

These numbers are reserved by TCP/IP for other uses.

For example, if you have three computers, you could number them as follows:

192.168.1.17

192.168.1.44

192.168.1.126

In this case, 17, 44, and 126 are arbitrary numbers between 1 and 254.

Each computer will also require a subnet mask, which is a numerical “filter”

that tells a computer what kinds of TCP/IP data packets to accept. If you’re not

sure which mask to use, the following mask is recommended:

255.255.255.0

Appendix C: Glossary

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).

Beacon Interval - A beacon is a packet broadcast by the Access Point to keep

the network synchronized. A beacon includes the wireless LAN service area,

the AP address, the Broadcast destination addresses, a time stamp, Delivery

Traffic Indicator Maps, and the Traffic Indicator Message (TIM).

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

Also, the smallest form of data.

Browser - A browser is an application program that provides a way to look at

and interact with all the information on the World Wide Web or PC. The word

“browser” seems to have originated prior to the Web as a generic term for user

interfaces that let you browse text files online.

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

devices to a wired network using a single access point.

Buffer - A buffer is a shared or assigned memory area used by hardware

devices or program processes that operate at different speeds or with different

sets of priorities. The buffer allows each device or process to operate without

DHCP supports static addresses for computers containing Web servers that

need a permanent IP address.

Download - To receive a file transmitted over a network. In a communications

session, download means receive, upload means transmit.

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

between a device and the upper-layer protocol software running in the comput-

er; it is designed for a specific device, and is installed during the initial instal-

lation of a network-compatible client or server operating system.

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

pattern for all transmitted data. 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).

DTIM (Delivery Traffic Indication Message) - A DTIM field is a countdown

field informing clients of the next window for listening to broadcast and mul-

ticast messages. When the AP has buffered broadcast or multicast messages for

associated clients, it sends the next DTIM with a DTIM Interval value. AP

Clients hear the beacons and awaken to receive the broadcast and multicast

messages.

Dynamic IP Address - An IP address that is automatically assigned to a client

station in a TCP/IP network, typically by a DHCP server. Network devices that

serve multiple users, such as servers and printers, are usually assigned static IP

addresses.

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.

ESS (Extended Service Set) - A set of more than two or more BSSs (multiple

access points) forming a single network.

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

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

being held up by the other. In order for a buffer to be effective, the size of the

buffer and the algorithms for moving data into and out of the buffer need to be

considered by the buffer designer. Like a cache, a buffer is a "midpoint holding

place” but exists not so much to accelerate the speed of an activity as to sup-

port the coordination of separate activities.

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.

CSMA/CD (Carrier Sense Multiple Access/Collision Detection) - The LAN

access method used in Ethernet. When a device wants to gain access to the net-

work, it checks to see if the network is quiet (senses the carrier). If it is not, it

waits a random amount of time before retrying. If the network is quiet and two

devices access the line at exactly the same time, their signals collide. When the

collision is detected, they both back off and each wait a random amount of time

before retrying.

Database - A database is a collection of data that is organized so that its con-

tents can easily be accessed, managed, and updated.

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.

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 Address - In the most widely installed level of the Internet Protocol

(Internet Protocol) today, an IP address is a 32-binary digit number that identi-

fies 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.

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 - A local area network (LAN) is 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.

Multicasting - Sending data to a group of nodes instead of a single destination.

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

the center frequency of a conventional carrier several times per second accord-

ing to a pseudo-random set of channels, while chirp spread spectrum changes

the carrier frequency. Because a fixed frequency is not used, illegal monitoring

of spread spectrum signals is extremely difficult, if not downright impossible

depending on the particular method.

Firmware - Code that is written onto read-only memory (ROM) or program-

mable read-only memory (PROM). Once firmware has been written onto the

ROM or PROM, it is retained even when the device is turned off.

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.

Hub - The device that serves as the central location for attaching wires from

workstations. Can be passive, where there is no amplification of the signals; or

active, where the hubs are used like repeaters to provide an extension of the

cable that connects to a workstation.

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.

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

network and is case-sensitive. Also known as “ESSID.”

Static IP Address - A permanent IP address that is assigned to a node in an IP

or a TCP/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 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.

TCP (Transmission Control Protocol) - A method (protocol) used along with

the IP (Internet Protocol) to send data in the form of message units (datagram)

Instant Wireless

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.

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

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

encryption process by automatically generating the WEP encryption keys for

Linksys products.

PC Card - A credit-card sized removable module that contains memory, I/O,

or a hard disk.

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.

RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that

holds up to eight wires, used for connecting Ethernet devices.

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.

Router - Protocol-dependent device that connects subnetworks together.

Routers are useful in breaking down a very large network into smaller subnet-

works; they introduce longer delays and typically have much lower throughput

rates than bridges.

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

to the receiving station requesting permission to transmit.

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

to files, printing, communications, and other services.

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 anoth-

er 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.

Upgrade - To replace existing software or firmware with a newer version.

Upload - To transmit a file over a network. In a communications session,

upload means transmit, download means receive.

UTP - Unshielded twisted pair is the most common kind of copper telephone

wiring. Twisted pair is the ordinary copper wire that connects home and many

business computers to the telephone company. To reduce crosstalk or electro-

magnetic induction between pairs of wires, two insulated copper wires are

twisted around each other. Each signal on twisted pair requires both wires.

Since some telephone sets or desktop locations require multiple connections,

twisted pair is sometimes installed in two or more pairs, all within a single

cable.

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

bit, 128-bit, or 256-bit shared key algorithm, as described in the IEEE 802.11

standard.
