Appendix: Glossary
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
300Mbps 802.11n Wireless USB Adapter
WNL-U556M
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
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 (Industrial, Scientific and Medical) band. Spectrum in the vicinity of
2.4 GHz, in particular, is being made available 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.
300Mbps 802.11n Wireless USB Adapter

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
300Mbps 802.11n Wireless USB Adapter
WNL-U556M
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 IEEE802.11-1997 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.
29. 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.

32. 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.

Appendix: FAQ
1.
What is WMM?
Wi-Fi Multimedia (WMM), a group of features for wireless networks that improve the user
experience for audio, video and voice applications. WMM is based on a subset of the IEEE
802.11e WLAN QoS draft standard. WMM adds prioritized capabilities to Wi-Fi networks and
optimizes their performance when multiple concurring applications, each with different latency and
throughput requirements, compete for network resources. By using WMM, end-user satisfaction is
maintained in a wider variety of environments and traffic conditions. WMM makes it possible for
home network users and enterprise network managers to decide which data streams are most
important and assign them a higher traffic priority.
2.
What is WMM Power Save?
WMM Power Save is a set of features for Wi-Fi networks that increase the efficiency and flexibility
of data transmission in order to conserve power. WMM Power Save has been optimized for
mobile devices running latency-sensitive applications such as voice, audio, or video, but can
benefit any Wi-Fi device. WMM Power Save uses mechanisms included in the IEEE 802.11e
standard and is an enhancement of IEEE 802.11 legacy power saves. With WMM Power Save,
the same amount of data can be transmitted in a shorter time while allowing the Wi-Fi device to
remain longer in a low-power “dozing” state.
3.
What is GI?
GI stands for Guard Interval. It’s a measure to protect wireless devices from cross- interference. If
there are two wireless devices using the same or near channel, and they are close enough, radio
interference will occur and reduce the radio resource usability.
4.
What is STBC?
STBC stands for Space-Time Block Coding, which is a technique used to transfer multiple copies
of data by multiple antenna, to improve data transfer performance. By using multiple antennas,
not only data transfer rate is improved, but also the wireless stability.
