6Glossary
1. IEEE 802.11 Standard
The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry.
2. Access Point
An internetworking device that seamlessly connects wired and wireless networks together.
3. Ad Hoc
An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent
wireless LAN. Ad Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.
4. BSSID A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be
configured with the same BSSID.
5. DHCP
Dynamic Host Configuration Protocol - a method in which IP addresses are assigned by server dynamically
to clients on the network. DHCP is used for Dynamic IP Addressing and requires a dedicated DHCP server
on the network.
6. Direct Sequence Spread Spectrum
This is the method the wireless cards use to transmit data over the frequency spectrum. The other method is
frequency hopping. Direct sequence spreads the data over one frequency range (channel) while frequency
hopping jumps from one narrow frequency band to another many times per second.
7. ESSID
An Infrastructure configuration could also support roaming capability for mobile workers. More than one
BSS can be configured as an Extended Service Set (ESS). Users within an ESS could roam freely between
BSSs while served as a continuous connection to the network wireless stations and Access Points within an
ESS must be configured with the same ESSID and the same radio channel.
8. Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users must be wired to the
network at all times to gain access.
9. Gateway
A gateway is a hardware and software device that connects two dissimilar systems, such as a LAN and a
mainframe. In Internet terminology, a gateway is another name for a router. Generally a gateway is used as a
funnel for all traffic to the Internet.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
18. 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.
19. Transmit / Receive
The wireless throughput in Bytes per second averaged over two seconds.
20. 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.
21. 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.
22. 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.
23. 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.
24. 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).
25. 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 close to the maximum value as possible.
26. 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.
27. 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 "heartbeat" 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).
28. 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 the short is 56 bits.
WPA2
It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the 802.11
standard.
30. 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.
31. 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.
