Dual-Band Wireless A+B Notebook Adapter
Chapter 1:Introduction
The Linksys Dual-Band Wireless A+B Notebook Adapter lets your notebook
communicate with today’s wireless network standard and prepares you for the
future. With one PC Card, you can connect with the 2.4GHz, 802.11b wireless
networks so prevalent in homes, businesses and public “hotspots” already, and
also a growing number of 5GHz, 802.11a networks that are spreading across
the country.
It’s simple to use. Just pop it into a PC Card slot, and run the included Setup
Wizard, which will walk you through the configuration. To keep your communications secure, the PC Card supports up to 152-bit data encr yption.
802.11b wireless networks are commonly found in corporate en vironments and
are used in homes for household Internet connectivity without the need for running cables. They’re also popping up all over the country in coffee shops, airports, hotels, convention centers, and other public spaces offering “on-the-go”
connectivity to mobile users. The 802.11a standard is almost five times faster
than 802.11b, and operates in the less crowded 5GHz radio band, but it’s not as
common—yet. It is quickly being deployed wherever higher-speed connectivity is desired.
Join the wireless revolution. With the Linksys Dual-Band Wireless Notebook
Adapter, you’ll be ready to connect to either type of wireless network, wherever you go, now and in the future.

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 wireless transmitters and receivers to communicate directly with each other, eliminating the need for an access point. The drawback of this mode is that, in AdHoc 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 directly between them.

Figure 2-2
Chapter 2:Planning You r Wireless Network
A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless de vice 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 conf igura-
tion is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating 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 printer, 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 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.

As the user moves on, the end node’s RF transmitter regularly checks the system 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 tr uly 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 developed by the military for use in reliable, secure, mission-critical communications 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 backg round
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 transmission, 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.
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 computers 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 continuously while mo ving freel y throughout an area greater than that co vered b y a single 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 coverage 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 undertakes 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.

Appendix B:Glossary
802.11a - 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 maximum
data transfer rate of 54Mbps and an operating frequency of 5GHz. The 802.11a
standard uses the Orthogonal Frequency Division Multiplexing (OFDM) transmission method. Additionally, the 802.11a standard supports 802.11 features
such 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 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.
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.
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 router 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 connection 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 distribute 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.
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 feature 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.

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 infrastructure 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). Infrastr ucture 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 (IP)
today, an IP address is a 32-binary digit number that identif ies 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 requester or the e-mail sender and can respond
by sending another message using the IP address it received.
IPCONFIG - A utility that provides for quer ying, defining and managing IP
addresses within a network. A commonly used utility, under Windows NT and
2000, for configuring networks with static IP addresses.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as W eb site
building and virtual hosting.
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 Address - The MAC (Media Access Control) address is your computer’s
unique hardware number.
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 especially useful in education and other environments where users change frequently. 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.
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 endpoint), the DSSS signal is recognized as the only valid signal, and interference
is inherently rejected (ignored).
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.
ESS (Extended Service Set) - A set of more than two or more BSSs (multiple
access points) forming a single network.
Firmware - Code that is written onto read-only memory (ROM) or prog rammable read-only memory (PROM). Once firmware has been written onto the
ROM or PROM, it is retained even when the device is turned off.
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 wellbeing of our members.”

Subnet Mask - The method used for splitting IP networks into a series of subgroups, 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 f ield for subnets.
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 netw ork 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 efficient delivery over the network. TCP is known as a "connection oriented" protocol 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.
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 netw ork devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), UDP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. UDP is known as a “connection-less” protocol
due to NOT requiring the receiver of a packet to retur n an acknowledgment of
receipt to the sender of the packet (as opposed to TCP).
WEP (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 utility 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.
mIRC - mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining and leaving channels.
Network Mask - also known as the “Subnet Mask.”
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 lowerspeed 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 applications, including powerline networking.
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.
Roaming - In an infrastructure mode wireless network, this refers to the ability 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.
SSID (Service Set Identifier) - An identification name that wireless devices
use to make connections. In order for wireless devices to communicate, they
must all be set to the same channel and they all must use the same SSID. For
instance, if you are using an access point to connect two computers using wireless devices, the access point and each of the wireless devices must use the
same SSID. Even if they are set to the same channel, they cannot communicate
unless the SSID is the same.
Static IP Address - A permanent IP address that is assigned to a node in a
TCP/IP network.
