You MUST select the option to match the Wireless LAN
you wish to join. The available options are:
z Open: Broadcast signals are not encrypted. This
method can be used only with no encryption or with
WEP.
z Shared: Broadcast signals are encrypted using WEP.
This method can only be used with WEP.
z LEAP: Light Extensible Authentication Protocol is a
pre-EAP, Cisco-proprietary protocol. If selected, you
have to enter the identity, password and domain name
of your computer.
z WPA: This version of WPA requires a Radius Server
on your LAN to provide the client authentication
according to the 802.1x standard. Data transmissions
are encrypted using the WPA standard.
z WPA-PSK: PSK means "Pre-shared Key". You must
enter this Passphrase value; it is used for both
authentication and encryption.
z WPA2: This version of WPA2 requires a Radius Server
on your LAN to provide the client authentication
according to the 802.1x standard. Data transmissions
are encrypted using the WPA2 standard.
Encryption
Use 802.1x
z WPA2-PSK: This is a further development of
WPA-PSK, and offers even greater security. You must
enter this Passphrase value; it is used for both
authentication and encryption.
z WPA None: If selected, you can only set encryption
and WPA-Preshared Key settings.
The available options depend on the Authentication
method selected above. The possible options are:
z None: No data encryption is used.
z WEP: If selected, you must enter the WEP data shown
below. This WEP data must match the Access Point or
other Wireless stations.
z AES, TKIP: These options are available with
WPA-PSK, WPA2-PSK, WPA and WPA2. Select the
correct option.
This setting only takes effect when using WPA or WPA2
mode. If enabled, click the 802.1x tab to configure the

EAP Method
There are 5 methods in the drop-down list.
z PEAP: Protect Extensible Authentication Protocol. PEAP
transport securely authentication data by using tunneling
between PEAP clients and an authentication server. PEAP
can authenticate wireless LAN clients using only server-side
certificates, thus simplifying the implementation and
administration of a secure wireless LAN.
z TLS-Smart Card: Transport Layer Security. Provides for
certificate-based and mutual authentication of the client and
the network. It relies on client-side and server-side
certificates to perform authentication and can be used to
dynamically generate user-based and session-based WEP
keys to secure subsequent communications between the
WLAN client and the access point.
z TTLS: Tunneled Transport Layer Security. This security
method provides for certificate-based, mutual authentication
of the client and network through an encrypted channel.
Unlike EAP-TLS, EAP-TTLS requires only server-side
certificates.
z EAP-FAST: Flexible Authentication via Secure Tunneling. It
was developed by Cisco. Instead of using a certificate,
mutual authentication is achieved by means of a PAC
(Protected Access Credential) which can be managed
dynamically by the authentication server. The PAC can be
provisioned (distributed one time) to the client either
manually or automatically. Manual provisioning is delivery to
the client via disk or a secured network distribution method.
Automatic provisioning is an in-band, over the air,
distribution.

z MD5-Challenge: Message Digest Challenge. Challenge is
an EAP authentication type that provides base-level EAP
support. It provides for only one-way authentication - there is
no mutual authentication of wireless client and the network.
Select the desired option from the drop-down list.
After reconnecting the signal which broke up, you can enable
the session resumption to reduce the transferring packet to
accelerate the speed.
Enter the required data into the fields.

The TCP Window is the amount of data which a sender can
send on a particular connection before it gets an
acknowledgement back from the receiver that it has gotten
some of it. When the router or AP which the adapter is
connecting to has set up the TCP Window, you can enable the
parameter to meet the data size for the router or AP
connection. The larger TCP Window the better performance.

CCX (Cisco Compatible Extensions) is developed by Cisco for
the radio monitoring and fast roaming.
z Turn on CCKM: During normal operation, LEAP-enabled
client devices mutually authenticate with a new access
point by performing a complete LEAP authentication,
including communication with the main RADIUS server.
When you configure your wireless LAN for fast
re-association, however, LEAP-enabled client devices
roam from one access point to another without involving the
main server. Using Cisco Centralized Key Management
(CCKM), an access point configured to provide Wireless
Domain Services (WDS) takes the place of the RADIUS
server and authenticates the client so quickly that there is
no perceptible delay in voice or other time-sensitive
applications.
z Enable Radio Measurement: When this parameter is
enabled, the Cisco AP can run the radio monitoring through
the associated CCX-compliant clients to continuously
monitor the WLAN radio environment and discover any new
Aps that are transmitting beacons.

or single fiber optic cable
100Base-TX
Also known as 802.3u. The IEEE standard defines how to transmit Fast Ethernet 100Mbps
using Cat.5 UTP/STP cable. The 100Base-TX standard is backward compatible with the
10Mbps 10-BaseT standard.
1000Base-SX
Also known as 802.3z. The IEEE standard defines how to transmit gigabit Ethernet data
using multi-mode fiber optic cables. This standard allows transmission distance of 550
meter, which is more than 5 times longer than the 100-meter limitation of 1000Base-T. The
1000Base-SX cannot run in 100Mbps mode.
1000Base-LX
The IEEE standard defines how to transmit gigabit Ethernet data using single mode fiber
optic cables. This standard allows transmission distance of 5km or more using single mode
fiber. The 1000Base-LX cannot run in 100Mbps mode.
1000Base-T

speed, and is backward compatible with 10/100Base-TX standard.
802.11a
An IEEE specification for wireless networking that operates in the 5 GHz frequency range
(5.15 GHz to 5.850 GHz) with a maximum of 54 Mbps data transfer rate. The 5 GHz
frequency band is not as crowded as the 2.4 GHz band. In addition, the 802.11a have 12
non-overlapping channels, comparing to 802.11b/g's 3 non-overlapping channels. This
means the possibility to build larger non-interfering networks. However, the 802.11a deliver
shorter distance at the same output power when comparing to 802.11g.
802.3ad
802.3ad is an IEEE standard for bonding or aggregating multiple Ethernet ports into one
virtual port (also known as trunking) to increase the bandwidth.
802.3af
This is the PoE (Power over Ethernet) standard by IEEE committee. 803.af uses 48V
POE standard that can deliver up to 100 meter distance over Ethernet cable.
802.11b
International standard for wireless networking that operates in the 2.4 GHz frequency band
(2.4 GHz to 2.4835 GHz) and provides a throughput up to 11 Mbps.
802.1d STP
Spanning Tree Protocol. It is an algorithm to prevent network from loop topology. Spanning
tree allows a network design to include spare (redundant) links to provide automatic backup
paths if an active link fails, without the danger of bridge loops, or the need for manual
enabling/disabling of these backup links. Bridge loop must be avoided because of flooding
issue in the network.
802.11d
39
AirLive WN-200USB User’s Manual
Page 43
6. Network Glossary
Also known as “Global Roaming”. 802.11d is a standard for use in countries where
systems using other standards in the 802.11 family are not allowed to operate.
802.11e
The IEEE QoS standard for prioritizing traffic of the VoIP and multimedia applications.
The WMM is based on a subset of the 802.11e.
802.11g
A standard provides a throughput up to 54 Mbps using OFDM technology. It also
operates in the 2.4 GHz frequency band as 802.11b. 802.11g devices are backward
compatible with 802.11b devices.
802.11h
This IEEE standard define the TPC (transmission power control) and DFS(dynamic
frequency selection) required to operate WiFi devices in 5GHz for EU.
802.11i
The IEEE standard for wireless security. 802.11i standard includes TKIP, CCMP, and
AES encryption to improve wireless security. It is also know as WPA2.
802.1Q Tag VLAN
In 802.1Q VLAN, the VLAN information is written into the Ethernet packet itself. Each
packet carries a VLAN ID(called Tag) as it traveled across the network. Therefore, the
VLAN configuration can be configured across multiple switches. In 802.1Q spec, possible
4096 VLAN ID can be created. Although for some devices, they can only view in frames
of 256 ID at a time.
802.1x
AirLive WN-200USB User’s Manual
40
Page 44
6. Network Glossary
802.1x is a security standard for wired and wireless LANs. In the 802.1x parlance, there are
usually supplicants (client), authenticator (switch or AP), and authentication server (radius
server) in the network. When a supplicants request a service, the authenticator will pass
the request and wait for the authentication server to grant access and register accounting.
The 802.1x is the most widely used method of authentication by WISP.
Adhoc
A Peer-to-Peer wireless network. An Adhoc wireless network do not use wireless AP or
router as the central hub of the network. Instead, wireless client are connected directly to
each other. The disadvantage of Adhoc network is the lack of wired interface to Internet
connections. It is not recommended for network more than 2 nodes.
Access Point (AP)
The central hub of a wireless LAN network. Access Points have one or more Ethernet
ports that can connect devices (such as Internet connection) for sharing. Multi-function
Access Point can also function as an Ethernet client, wireless bridge, or repeat signals from
other AP. Access Points typically have more wireless functions comparing to wireless
routers.
Cable and Connector Loss
: During wireless design and deployment, it is important to
factor in the cable and connector loss. Cable and connector loss will reduce the output
power and receiver sensitivity of the radio at connector end. The longer the cable length is,
the more the cable loss. Cable loss should be subtracted from the total output power
during distance calculation. For example, if the cable and connector loss is 3dBm and the
output power is 20dBm; the output power at the cable end is only 17dBm.
Client
Client means a network device or utility that receives service from host or server. A client
device means end user device such as wireless cards or wireless CPE.
DHCP
41
AirLive WN-200USB User’s Manual
Page 45
6. Network Glossary
Dynamic Hosting Configuration Protocol. A protocol that enables a server to dynamically
assign IP addresses. When DHCP is used, whenever a computer logs onto the network, it
automatically gets an IP address assigned by DHCP server. A DHCP server can either be a
designed PC on the network or another network device, such as a router.
Encryption
Encoding data to prevent it from being read by unauthorized people. The common
wireless encryption schemes are WEP, WPA, and WPA2.
ESSID (SSID)
The identification name of an 802.11 wireless network. Since wireless network has no
physical boundary liked wired Ethernet network, wireless LAN needs an identifier to
distinguish one network from the other. Wireless clients must know the SSID in order to
associate with a WLAN network. Hide SSID feature disable SSID broadcast,
so users must know the correct SSID in order to join a wireless network.
Firmware
The program that runs inside embedded device such as AP or Switch. Many network
devices are firmware upgradeable through web interface or utility program.
FTP
File Transfer Protocol. A standard protocol for sending files between computer over a
TCP/IP network and the internet.
Fragment Threshold
Frame Size larger than this will be divided into smaller fragment. If there are interferences
in your area, lower this value can improve the performance. If there are not, keep this
parameter at higher value. The default size is 2346. You can try 1500, 1000, or 500
when there are interference around your network.
AirLive WN-200USB User’s Manual

6. Network Glossary
Full Duplex
The ability of a networking device to receive and transmit data simultaneously. In wireless
environment, this is usually done with 2 or more radios doing load balancing.
Gateway
In the global Internet network, the gateways are core routers that connect networks in
different IP subnet together. In a LAN environment with an IP sharing router, the gateway
is the router. In an office environment, gateway typically is a multi-function device that
integrates NAT, firewall, bandwidth management, and other security functions.
GI
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. In an OFDM system, the
length of the guard interval needs to be changed according to the environment to make
efficient use of the communication channels. In General, you will see SGI (Short Guard
Interval) or LGI (Long Interval Guard).
Hotspot
A place where you can access Wi-Fi service. The term hotspot has two meanings in
wireless deployment. One is the wireless infrastructure deployment, the other is the
Internet access billing system. In a hotspot system, a service provider typically need an
authentication and account system for billing purposes, and a wireless AP network to
provide access for customers.
IGMP Snooping
Internet Group Management Protocol. It is a Layer 3 protocol to report IP multicast
memberships to neighboring multicast switches and routers. IGMP Snooping is a feature
that allows an Ethernet Switch to “listen in” on the IGMP conversation between hosts and
routers. When IGMP snooping is enabled in a switch, it prevent hosts on a local network
from receiving traffic for a multicast group they have not explicitly joined. It provides
switches with a mechanism to prune multicast traffic from links that do not contain a
multicast listener (IGMP client).

Infrastructure Mode
A wireless network that is built around one or more access points to provide wireless clients
access to wired LAN / Internet service. The opposite of Infrastructure mode is Adhoc
mode.
IP Address
IP (Internet Protocol) is a Layer 3 network protocol that is the basis of all Internet
communication. An IP address is 32-bit number that identifies each sender or receiver of
information that is sent across the Internet. An IP address has two parts: an identifier of a
particular network on the Internet and an identifier of the particular device (which can be a
server or a workstation) within that network. The new IPv6 specification supports 128-bit IP
address format.
IPsec
IP Security. A set of protocols developed by the IETF to support secure exchange of
packets at the IP layer. IPsec has been deployed widely to implement Virtual Private
Networks (VPNs). IPsec supports two encryption modes: Transport and Tunnel.
Transport mode encrypts only the data of each packet, but leaves the header untouched.
The more secure Tunnel mode encrypts both the header and the payload. On the receiving
side, an IPSec-compliant device decrypts each packet.
LACP (802.3ad) Trunking
Link Aggregation Control Protocol. It is protocol defines how to combine the several
Ethernet ports into one high-bandwidth port to increase the transmission speed. It is also
known as port trunking. Both devices must set the trunking feature to work.
MAC
Media Access Control. MAC address provides Layer-2 identification for network devices.
Each Ethernet device has its own unique address. The first 6 digits are unique for each
device manufacturers. When a network device has MAC access control feature, only the
devices with the approved MAC address can connect with the network.

MESH
Mesh is an outdoor wireless technology that uses Spanning Tree Protocol (STP) and
Wireless Distribution system to achieve self-forming, self-healing, and self-configuring
outdoor network. MESH network are able to take the shortest path to a destination that
does not have to be in the line of site.
MIMO
Multi In Multi Out. A Smart Antenna technology designed to increase the coverage and
performance of a WLAN network. In a MIMO device, 2 or more antennas are used to
increase the receiver sensitivity and to focus available power at intended Rx.
NAT
Network Address Translation. A network algorithm used by Routers to enables several
PCs to share single IP address provided by the ISP. The IP that a router gets from the
ISP side is called Real IP, the IP assigned to PC under the NAT environment is called
Private IP.
Node
A network connection end point, typically a computer.
Packet
A unit of data sent over a network.
Passphrase

6. Network Glossary
Used much like a password, a passphrase simplifies the WEP encryption process by
automatically generating the WEP encryption keys for the company products.
Port
This word has 2 different meaning for networking.
The hardware connection point on a computer or networking device used for plugging
z
in a cable or an adapter.
The virtual connection point through which a computer uses a specific application on a
z
server.
PPPoE
Point-to- Point Protocol over Ethernet. PPPoE relies on two widely accepted standards:
PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the
Internet through a common broadband medium, such as a single DSL line, wireless device
or cable modem.
PPTP
Point-to-Point Tunneling Protocol: A VPN protocol developed by PPTP Forum. With
PPTP, users can dial in to their corporate network via the Internet. If users require data
encryption when using the Windows PPTP client, the remote VPN server must support
MPPE (Microsoft Point-To-Point Encryption Protocol) encryption. PPTP is also used by
some ISP for user authentication, particularly when pairing with legacy Alcatel / Thomson
ADSL modem.
Preamble Type
Preamble are sent with each wireless packet transmit for transmission status. Use the
long preamble type for better compatibility. Use the short preamble type for better
performance.

Rate Control
It is an Ethernet switch’s function to control the upstream and downstream speed of an
individual port. Rate control management use “Flow Control” to limit the speed of a port.
Therefore, the Ethernet adapter must also have the flow control enabled. One way to force
the adapter’s flow control on is to set a port to half-duplex mode.
RADIUS
Remote Authentication Dial-In User Service. An authentication and accounting system
used by many Internet Service Providers (ISPs). When you dial in to the ISP, you must
enter your username and password. This information is passed to a RADIUS server, which
checks that the information is correct, and then authorizes access to the ISP system.
Radius typically uses port 1812 and port 1813 for authentication and accounting port.
Though not an official standard, the RADIUS specification is maintained by a working group
of the IETF.
Receiver Sensitivity
Receiver sensitivity means how sensitive is the radio for receiving signal. In general; the
slower the transmission speed, the more sensitive the radio is. The unit for Receiver
Sensitivity is in dB; the lower the absolute value is, the higher the signal strength. For
example, -50dB is higher than -80dB.
RJ-45
Standard connectors for Twisted Pair copper cable used in Ethernet networks. Although
they look similar to standard RJ-11 telephone connectors, RJ-45 connectors can have up to
eight wires, whereas telephone connectors have only four.
Router
An IP sharing router is a device that allows multiple PCs to share one single broadband
connection using NAT technology. A wireless router is a device that combines the
functions of wireless Access Point and the IP sharing router.

6. Network Glossary
RSSI
Receiver Sensitivity Index. RSSI is a value to show the Receiver Sensitivity of the remote
wireless device. In general, remote APs with stronger signal will display higher RSSI
values. For RSSI value, the smaller the absolute value is, the stronger the signal. For
example, “-50db” has stronger signal than “-80dB”. For outdoor connection, signal
stronger than -60dB is considered as a good connection.
RTS
Request To Send. A packet sent when a computer has data to transmit. The computer will
wait for a CTS (Clear To Send) message before sending data.
RTS Threshold
RTS (Request to Send). The RTS/CTS(clear to send) packet will be send before a frame
if the packet frame is larger than this value. Lower this value can improve the
performance if there are many clients in your network. You can try 1500, 1000 or 500
when there are many clients in your AP’s network.
SNMP
Simple Network Management Protocol. A set of protocols for managing complex networks.
The SNMP network contains three key elements: managed devices, agents, and
network-management system (NMS). Managed devices are network devices that contain
SNMP agents. SNMP agents are programs that reside SNMP capable device’s firmware to
provide SNMP configuration service. The NMS typically is PC-based software that can
monitor and control managed devices remotely.
SSH
Developed by SSH Communications Security Ltd., Secure Shell is a program to log into
another computer over a network, to execute commands in a remote machine, and to move
files from one machine to another. It provides strong authentication and secure
communications over insecure channels. It is a replacement for rlogin, rsh, rcp, and rdist.

SSL
Secure Sockets Layer. It is a popular encryption scheme used by many online retail and
banking sites to protect the financial integrity of transactions. When an SSL session
begins, the server sends its public key to the browser. The browser then sends a randomly
generated secret key back to the server in order to have a secret key exchange for that
session. SSL VPN is also known as Web VPN. The HTTPS and SSH management
interface use SSL for data encryption.
Subnet Mask
An address code mask that determines the size of the network. An IP subnet are
determined by performing a BIT-wise AND operation between the IP address and the
subnet mask. By changing the subnet mask, you can change the scope and size of a
network.
Subnetwork or Subnet
Found in larger networks, these smaller networks are used to simplify addressing between
numerous computers. Subnets connect to the central network through a router, hub or
gateway. Each individual wireless LAN will probably use the same subnet for all the local
computers it talks to.
Super A
Super A is an Atheros proprietary turbo mode to increase speed over standard 802.11a
mode. It adds Bursting and Compression to increase the speed. If you live in countries
that prohibit the channel binding technology (i.e. Europe), you should choose “Super-A
without Turbo) if you need more speed than 11a mode
TCP
A layer-4 protocol used along with the IP to send data between computers over the Internet.
While IP takes care of handling the actual delivery of the data, TCP takes care of keeping
track of the packets that a message is divided into for efficient routing through
the Internet.

Turbo A
Turbo A is an Atheros proprietary turbo mode to increase speed over standard 802.11a
mode. It uses channel binding technology to increase speed. There are 2 types of Turbo
A modes: Dynamic Turbo and Static Turbo. In Dynamic Turbo, the channel binding will be
used only if necessary. In Static Turbo, the channel binding is always on. This protocol
may be combined with Super-A model to increase the performance even more. The used
of channel binding might be prohibited in EU countries.
TX Output Power
Transmit Output Power. The TX output power means the transmission output power of
the radio. Normally, the TX output power level limit for 2.4GHz 11g/b is 20dBm at the
antenna end. The output power limit for 5GHz 802.11a is 30dBm at the antenna end..

802.16 standard call for operating frequency of 10 to 66Ghz spectrum. The 802.16a
amendment extends the original standard into spectrum between 2 and 11 Ghz. 802.16d
increase data rates to between 40 and 70 Mbps/s and add support for MIMO antennas,
QoS, and multiple polling technologies. 802.16e adds mobility features, narrower
bandwidth (a max of 5 mhz), slower speed and smaller antennas. Mobility is allowed up to
40 mph.

Wireless Router can connect together to form one single wireless network without using
wired uplinks. WDS associate each other by MAC address, each device
WLAN
Wireless Local Area Network. A type of local-area network that uses high-frequency radio
waves rather than wires to communicate between nodes. The most popular standard for
WLAN is the 802.11 standards.

WPA
Wi-Fi Protected Access. It is an encryption standard proposed by WiFi for advance
protection by utilizing a password key (TKIP) or certificate. It is more secure than WEP
encryption. The WPA-PSK utilizes pre-share key for encryption/authentication.
WPA2
Wi-Fi Protected Access 2. WPA2 is also known as 802.11i. It improves on the WPA
security with CCMP and AES encryption. The WPA2 is backward compatible with WPA.
WPA2-PSK utilizes pre-share key for encryption/authentication.
