Glossary
IEEE 802.11 Standard
The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry.
Access Point
An internetworking device that seamlessly connects wired and wireless networks together.
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.
BSSID
A specifi c Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a
BSS must be confi gured with the same BSSID.
59
Page 60
DHCP
Dynamic Host Confi guration 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.
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.
ESSID
An Infrastructure confi guration could also support roaming capability for mobile workers. More than one
BSS can be confi gured 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 confi gured with the same ESSID and the same radio channel.
60
Page 61
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/offi ce wiring. Users must be wired to
the network at all times to gain access.
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 traffi c to the Internet.
IEEE
Institute of Electrical and Electronics Engineers
Infrastructure
An integrated wireless and wired LAN is called an Infrastructure confi guration. Infrastructure is applicable
to enterprise scale for wireless access to central database, or wireless application for mobile workers.
61
Page 62
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, Scientifi c 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 highspeed 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, fi les, and messages can be transmitted over
this network. Networks may be local or wide area networks.
62
Page 63
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.
Roaming
In an infrastructure network, this is when a wireless PC moves out of range of the previously connected
access point and connects to a newly connected access point. Throughout the network environment
where access point is deployed, PCs can always be connected regardless of where they are located or
roam.
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.
63
Page 64
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol is the network management protocol of TCP/IP. In SNMP,
agents-which can be hardware as well as software - monitor the activity in the various devices on
the network and report to the network console workstation. Control information about each device is
maintained in a structure known as a management information block.
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 fi xing the fl aws of WEP.
64
Page 65
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.
Transmit / Receive
The wireless throughput in Bytes per second averaged over two seconds.
Wi-Fi Alliance
The Wi-Fi Alliance is a nonprofi t international association formed in 1999 to certify interoperability of
wireless Local Area Network products based on IEEE 802.11 specifi cation. 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.
65
Page 66
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 fi xes 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 fi ber optic cabling.
WANs may span a city, a state, a country, or even the world.
Wired Equivalent Privacy (WEP)
Now widely recognized as fl awed, 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 insuffi cient 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.
66
Page 67
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).
