Wireless LAN network defined by IEEE 802.11b/g standard committee
could be configured as :
Ad Hoc wireless LAN. Infrastructure wireless LAN.
Ad Hoc network is a group of PCs installed with wireless LAN cards, this group
of PCs is called a BSS (Basic Service Set). PCs in this group can use their
wireless LAN cards to communicate with each other, but can not connect to the
Internet.
Ad Hoc Wireless Network
Infrastructure Wireless Network
The most obvious difference between Infrastructure wireless network and Ad
Hoc wireless network is that the PCs in Infrastructure wireless network can
access the resource in the Internet through Access Point.
Depending on your requirement, you can easily set up your PC’s network to be
a “Ad Hoc” or “Infrastructure” wireless network. Generally speaking, if in
your network, there is an Access Point in it, we recommend you to set your
network as an “Infrastructure”, so it can connect to the Internet.
7
To use the Wireless-N USB Adapter with a computing device, the Wireless-N
USB Adapter must be equipped with a proper Interface. All drivers and
supporting software for the Wireless-N USB Adapter must be installed and
configured first.
Ask your system administrator for the following information, which you may
need to provide during driver installation :
‹ Your Wireless Client Name, Your Wireless SSID.
‹ Your computer’s unique client name and workgroup name. For your network
account, your user name and password.
‹ Your IP address, gateway address, and subnet mask if you’re not using a
DHCP client.
Any computer on a network is identified by a unique network address. There
are two methods to assign a network address to a computer on a TCP/IP
network :
‹ Static IP addressing.
‹ Dynamic IP addressing (DHCP Client).
In network with static IP addressing, the network administrator manually
assigns an IP address to each computer. Once a static IP address is assigned, a
computer uses the same IP address every time it reboots and logs on to the
network. You may manually change the IP address in the Network
Properties dialog box. Network using static IP address is easy to set up
and do not require additional network management software.
In network with dynamic IP addressing, a DHCP server in the network
dynamically assigns IP addresses to all clients every time they log on to the
network. Network using dynamic IP address requires setting up and running a
DHCP Server.

IEEE
Institute of Electrical and Electronics Engineers Infrastructure An integrated
wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central
database, or wireless application for mobile workers.
ISM Band
The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the so-called 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.
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network
adapter card connected by cable/air, that share applications, data, and
peripherals. All connections are made via cable or wireless media, but a LAN
does not use telephone services. It typically spans a single building or
campus.
Network
A network is a system of computers that is connected. Data, files, and
messages can be transmitted over this network. Networks may be local or
wide area networks.
Protocol
A protocol is a standardized set of rules that specify how a conversation is
to take place, including the format, timing, sequencing and/ or error
checking.
SSID
A Network ID unique to a network. Only clients and Access Points that share
the same SSID are able to communicate with each other. This string is
case-sensitive.
Static IP Addressing
A method of assigning IP addresses to clients on the network. In networks
with Static IP address, the network administrator manually assigns an IP
address to each computer. Once a Static IP address is assigned, a computer
uses the same IP address every time it reboots and logs on to the network,
unless it is manually changed.
Temporal Key Integrity Protocol (TKIP)
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE
802.11i encryption standard for wireless LANs. TKIP is the next generation
of WEP, the Wired Equivalency Protocol, which is used to secure 802.11
wireless LANs. TKIP provides per-packet key mixing, a message integrity
check and a re-keying mechanism, thus fixing the flaws of WEP.
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research Projects
Agency (ARPA). It is widely used in corporate Internet works, because of its
superior design for WANs. TCP governs how packet is sequenced for
transmission the network. The term “TCP/IP” is often used generically to
refer to the entire suite of related protocols.
20
Transmit / Receive
The wireless throughput in Bytes per second averaged over two seconds.
Wi-Fi Alliance
The Wi-Fi Alliance is a nonprofit international association formed in 1999 to
certify interoperability of wireless Local Area Network products based on
IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members is to
enhance the user experience through product interoperability. The
organization is formerly known as WECA.
Wi-Fi Protected Access (WPA)
The Wi-Fi Alliance put together WPA as a data encryption method for 802.11
wireless LANs. WPA is an industry-supported, pre-standard version of
802.11i utilizing the Temporal Key Integrity Protocol (TKIP), which fixes the
problems of WEP, including using dynamic keys.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone
services and / or fiber optic cabling. WANs may span a city, a state, a
country, or even the world.
Wired Equivalent Privacy (WEP)
Now widely recognized as flawed, WEP was a data encryption method used
to protect the transmission between 802.11 wireless clients and APs.
However, it used the same key among all communicating devices. WEP’s
problems are well-known, including an insufficient key length and no
automated method for distributing the keys. WEP can be easily cracked in a
couple of hours with off-the-shelf tools.
Wireless LAN (WLAN)
A wireless LAN does not use cable to transmit signals, but rather uses radio
or infrared to transmit packets through the air. Radio Frequency (RF) and
infrared are the commonly used types of wireless transmission. Most
wireless LANs use spread spectrum technology. It offers limited bandwidth,
usually under 11Mbps, and users share the bandwidth with other devices in
the spectrum; however, users can operate a spread spectrum device without
licensing from the Federal Communications Commission (FCC).
21
Fragment Threshold
The proposed protocol uses the frame fragmentation mechanism defined in
IEEE 802.11 to achieve parallel transmissions. A large data frame is
fragmented into several fragments each of size equal to fragment threshold.
By tuning the fragment threshold value, we can get varying fragment sizes.
The determination of an efficient fragment threshold is an important issue in
this scheme. If the fragment threshold is small, the overlap part of the
master and parallel transmissions is large. This means the spatial reuse
ratio of parallel transmissions is high. In contrast, with a large fragment
threshold, the overlap is small and the spatial reuse ratio is low. However
high fragment threshold leads to low fragment overhead. Hence there is a
trade-off between spatial re-use and fragment overhead.
Fragment threshold is the maximum packet size used for fragmentation.
Packets larger than the size programmed in this field will be fragmented If
you find that your corrupted packets or asymmetric packet reception (all
send packets, for example). You may want to try lowering your
fragmentation threshold. This will cause packets to be broken into smaller
fragments. These small fragments, if corrupted, can be resent faster than a
larger fragment. Fragmentation increases overhead, so you'll want to keep
this value as closeto the maximum value as possible.
RTS (Request To Send) Threshold
The RTS threshold is the packet size at which packet transmission is
governed by the RTS/CTS transaction. The IEEE 802.11-1997 standard
allows for short packets to be transmitted without RTS/CTS transactions.
Each station can have a different RTS threshold. RTS/CTS is used when the
data packet size exceeds the defined RTS threshold. With the CSMA/CA
transmission mechanism, the transmitting station sends out an RTS packet
to the receiving station, and waits for the receiving station to send back a
CTS (Clear to Send) packet before sending the actual packet data. This
setting is useful for networks with many clients. With many clients, and a
high network load, there will be many more collisions. By lowering the RTS
threshold, there may be fewer collisions, and performance should improve.
Basically, with a faster RTS threshold, the system can recover from
problems faster. RTS packets consume valuable bandwidth, however, so
setting this value too low will limit performance.
Beacon Interval
In addition to data frames that carry information from higher layers, 802.11
includes management and control frames that support data transfer. The
beacon frame, which is a type of management frame, provides the
"heartbea" of a wireless LAN, enabling stations to establish and maintain
communications in an orderly fashion. Beacon Interval represents the
amount of time between beacon transmissions. Before a station enters
power save mode, the station needs the beacon interval to know when to
wake up to receive the beacon (and learn whether there are buffered
frames at the access point).
Preamble Type
There are two preamble types defined in IEEE 802.11 specification. A long
preamble basically gives the decoder more time to process the preamble. All
802.11 devices support a long preamble. The short preamble is designed to
improve efficiency (for example, for VoIP systems). The difference between
the two is in the Synchronization field. The long preamble is 128 bits, and
theshort is 56 bits.
22
WPA2
It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i
amendment to the 802.11 standard.
Temporal Key Integrity Protocol (TKIP)
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE
802.11i encryption standard for wireless LANs. TKIP is the next generation
of WEP, the Wired Equivalency Protocol, which is used to secure 802.11
wireless LANs. TKIP provides per-packet key mixing, a message integrity
check and a re-keying mechanism, thus fixing the flaws of WEP.
802.1x Authentication
802.1x is a framework for authenticated MAC-level access control, defines
Extensible Authentication Protocol (EAP) over LANs (WAPOL). The standard
encapsulates and leverages much of EAP, which was defined for dial-up
authentication with Point-to-Point Protocol in RFC 2284.
Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL
messages that convey the shared key information critical for wireless
security.
Advanced Encryption Standard (AES)
Security issues are a major concern for wireless LANs, AES is the U.S.
government’s next-generation cryptography algorithm, which will replace
DES and 3DES.
