SAMPLE APPLICATION
Figure 1 shows a basic application where the AirborneDirect™ Serial Bridge is exchanging data
wirelessly between a serial client and a LAN host. In this application:
ƒ
The serial client can be a notebook personal computer (PC), or other Data
Terminal Equipment (DTE) whose serial port is directly connected to the
AirborneDirect™ Serial Bridge.
ƒ
The LAN host can be a PC or PDA running a HyperTerminal or Telnet session,
Web Browser, or LAN-based application. The LAN host communicates with the
AirborneDirect™ Serial Bridge over a wireless network connection via an attached
Access Point or directly in Ad Hoc mode.

Introduction
Figure 2 shows a sample application that uses the AirborneDirect™ Serial Bridge and the
VCOM driver from Quatech. In this application, a customer device (or “serial client”) is an
instrument or data logger that is connected directly to the Bridge and exchanges data wirelessly
with an Access Point. The Access Point is connected to the company LAN. Also connected to
the company LAN is a remote PC (or “LAN host”). The LAN host is running a customer
application that collects data from the serial client and stores it in a database. The VCOM driver
installed on the LAN host allows the collected data to pass to the customer’s application, without
requiring modifications to the PC hardware or software.

SELECTING A LOCATION
You can mount the Bridge on a flat surface, such as a desk or table, or on a vertical surface,
such as a wall. It can also be mounted on the ceiling. If you mount the Bridge vertically, use the
supplied mounting cradle previously described.
Choosing a good location for the Bridge is important because it affects the reliability of the
wireless link. The most important considerations are distance from the Access Point and
clearance from obstacles.
The location you choose for installing the Bridge must:
ƒ
Provide sufficient ventilation around the Bridge.
ƒ
Allow easy access to disconnect the Bridge from the AC wall outlet if necessary.
ƒ
Not expose the Bridge to excessive heat, humidity, vibration, or dust.
ƒ
Must conform to local regulations.
Because radio waves travel in a straight line, the location where you will install the Bridge must
provide a clear path to the Access Point that is free of major obstacles. The effects of obstacles,
both along and near the path, have a significant bearing on the travel of radio signals and can
cause both interference and signal cancellation. Consider the effects of the following common
obstacles:
Page 20
ƒ
Trees and large plants
A tree or large plant directly in the path can totally block the signal. With clearance
above the trees, there are usually no blocking effects.
ƒ
Man-made obstacles
Square or rectangular objects, in or near the path, have rectangular surfaces that
can block and interfere with signals over and around them.
ƒ
Floor
A floor can interfere with signals if the Bridge is mounted too low. Mount the Bridge
so the antenna is high enough to allow adequate clearance from the floor.

Hardware Installation
CONNECTING THE BRIDGE
Use the following procedure to connect the Bridge:
•
Place the Bridge in a dry, clean location near the device to which it will be connected.
The location is required to have a power source and should be within 300 feet (100
meters) of a Wi-Fi compliant wireless LAN Access Point. The location should be away
from transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators
or other equipment that could cause radio-signal interference.
•
Connect the male, DB9 DTE connector on the Bridge’s serial cable to a female, DCE
serial port on your device. If your device has a 9-pin male DTE connector, use the
female-to-female null-modem adapter supplied with the Evaluation Kit (or equivalent) to
make this connection.
•
Raise the antenna on the Bridge so it is pointing vertically.
•
If your Access Point is using WEP or WPA, disable the security. You can re-enable WEP
or WPA after the Bridge has been configured.
•
Connect the supplied power adapter to the Bridge and to a grounded 110/240V, 5060Hz power source.

Verifying Your Connections (page 25)
ƒ
WPA-LEAP Security (page 24)
WIRELESS CONFIGURATION
After you verify that the indicator LEDs have gone through their power-up sequence, start the
configuration application for your Access Point (your Access Point manual should describe this
procedure). Then go the appropriate screen in the application and perform the following steps:
Access Point configuration applications vary between models and
Note: manufacturers. In the following steps, there are suggested screen names where
you might find the Access Point settings required to operate the Bridge. The
screens in your Access Point’s configuration application may differ from those
mentioned below. Refer to the documentation that came with your Access Point
to locate the appropriate screens where these settings can be accessed.
•
Find the Service Set Identifier String (SSID)
Go to the Wireless Settings or equivalent screen in your Access Point’s configuration
application that shows the Access Point’s SSID. Record the SSID in Table 4 (on
page 24). You will need this information to configure the Bridge.
•
Disable Wireless Security
Go to the Wireless Settings, Security, Encryption, or equivalent screen in your
Access Point’s configuration application that shows the WEP/WPA setting. If WEP or
WPA is enabled, disable it (you can enable the AP security after the Bridge has been
configured).
•
Find the Bridge’s Internet Protocol (IP) Address
Go to the Attached Devices or equivalent screen in your Access Point’s configuration
application that lists the IP addresses of devices attached to the Access Point. Find
the IP address for the Bridge and record it in Table 4 (on page 24). You will need it to
access the Bridge with the Airborne Control Center (ACC).

Initial Configuration
If you do not see the Bridge as an attached device, refresh the configuration
Note: screen (some Access Point programs provide a Refresh button for this
purpose). If the Bridge still does not appear, refer to the troubleshooting chapter
in this Guide and in the documentation for your Access Point.
Note:
You can also use the device discovery feature of the Airborne Control Center
software (see page 29) to help determine the Bridge’s IP address.
X
•
Verify the MAC Address
Go to the Attached Devices or equivalent screen in your Access Point’s configuration
application that lists the MAC addresses of attached devices. Verify that the MAC
address shown for the Bridge matches the one on the label on the back of the
Bridge.
•
Verify the Dynamic Host Configuration Protocol (DHCP) Name
Go to the Router Status or equivalent screen in your Access Point’s configuration
application that shows the Bridge’s DHCP client name. Verify that this name
matches the last six characters in the Bridge’s MAC address (AIRBORNExxxxxx) on
the label on the back of the Bridge.

Access Point’s SSID
Bridge’s IP address
Note:
If the Bridge is unable to obtain an IP address through DHCP, after the
acquire limit is exceeded (150 seconds) the bridge will install the fallback
IP address (192.168.10.1) and subnet (255.255.255.0).
The bridge can be accessed using this address, after DHCP fails, by the
attached host using a different IP address in the same subnet
(192.168.10.8).

VERIFYING YOUR CONNECTIONS
When the Bridge is powered-up, the indicator LEDs at the top of the Bridge will indicate the
status of the Bridge. See Table 2 on page 15 for standard packaging, or Table 3 on page 19 for
Heavy-Duty packaging.
If the LEDs indicate a problem with a wired or wireless connection, remove the power source
from the Bridge, wait a few seconds, and re-apply power. If the LEDs still do not behave
appropriately, see the guidelines in Table 12 on page 73.
Other Access Points in the area may interfere with the Bridge’s ability to
Note: associate with your chosen Access Point (the Bridge will try to associate with
the first available “best-quality” AP). If you encounter difficulties with connecting
to your chosen AP, either remove power from these Access Points or move to
an isolated location and perform the setup shown in Figure 1 on page 3.

Initial Configuration
WPA-LEAP SECURITY
The WPA and LEAP software modules provide advanced security configuration and
communication services required by today’s enterprise-class deployments.
Please refer to IEEE standard 802.1x 2001 (section 4) and IEEE standard 802.11i 2004 (section
4) for additional information.
System Requirements
For the 802.11b Bridge, both WPA and LEAP require radio firmware version 1.1.1.111.8.4 or
later. All versions of the 802.11b/g Bridge support WPA and LEAP. The AP requires WPA
support. LEAP must be supported in the AP or a separate authentication server.
Computer Resource Requirements
WPA-PSK
In order to function properly, an Access Point that supports WPA-PSK must be available. The
WPA-PSK passphrase installed on the Access Point must match the passphrase configured on
the bridge.
LEAP
In order to function properly, a RADIUS server configured for LEAP containing
usernames/passwords, and an Access Point that supports LEAP, must be available. The
RADIUS server username and password must match the user-leap and pw-leap command
values configured on the bridge.
The blank character (space) may not be included in a passphrase or LEAP
Note: password.
System Implementation Considerations
The bridge must be in infrastructure mode for WPA-PSK or LEAP to operate properly. A bridge
configured for WPA-PSK requires a connection to an AP with WPA-PSK enabled. A bridge
configured for LEAP requires a connection to an AP with LEAP enabled and connected to a
RADIUS server to provide authentication.
Until the bridge is authenticated by either the WPA-PSK enabled AP or the RADIUS server, no
IP network communication can proceed.
Symptoms of an unauthenticated client include:
ƒ
A bridge with serial-default set to “PASS” will not connect to the network client.
Page 26
AirborneDirect™ Serial Bridge User’s Guide
Quatech, Inc. Confidential
100-8006-152G
Initial Configuration
ƒ
A bridge configured for DHCP will not obtain host configuration from the DHCP server;
therefore, the IP address will remain 0.0.0.0.
ƒ
The Link LED turns green when 802.11 association completes. However, if the 802.1x
authentication fails, the bridge becomes disassociated by the AP and the Link LED goes
back to flashing red.
ƒ
The bridge will not respond to discovery requests.
Once the bridge is authenticated, additional impacts include:
ƒ
Roaming
A bridge configured for WPA-PSK can only roam to APs that have WPA-PSK enabled in
the same ESS.
A bridge configured for LEAP can only roam to APs that support LEAP, roaming, and are
connected to the same RADIUS server.
ƒ
Data Throughput and Latency
Round trip latency may increase and overall throughput may decrease, due to the
additional steps to encrypt or decrypt data.
ƒ
Re-Keying
The session key may expire and the authentication process will be executed again
causing streaming data to stop until a new key is authorized.

OVERVIEW
VCOM is a serial-to-IP redirector driver and configuration utility for Microsoft® Windows® XP and
Windows 2000. Using this utility, you can create a virtual communication (COM) port and
associate it with a network device that has a known Internet Protocol (IP) address.
The VCOM driver allows a LAN host computer to assign a virtual COM port to a remote device.
Once configured, this allows applications that communicate through COM ports to use a TCP/IP
network, without requiring changes to the application. This driver is designed specifically to
provide LAN connectivity for the AirborneDirect™ Serial Bridge.

Using VCOM
DESCRIPTION OF VCOM COMPONENTS
The VCOM components consist of the following:
ƒ
Network Management Service (NMS)
ƒ
VCOM Serial Device Driver
ƒ
VCOM Configuration Utility
Network Management Service (NMS)
The Network Management Service (NMS) is a Microsoft® Windows® service that performs the
network-related operations for the VCOM serial device driver.
The NMS has two operating modes, pass-through mode and communications mode. In passthrough mode, the NMS authenticates with the Bridge and establishes a pass-through
connection with it. In this mode, data sent to the Bridge is forwarded to the host serial device.
In communications mode, the NMS establishes only a Transmission Control Protocol (TCP)
connection with the Bridge. The application or DLL is responsible for authenticating with the
Bridge, sending commands to it, and interpreting responses from it. In this mode the NMS is a
pass-through for communications through an application or DLL.
Note:
Communications mode is only available through the DPAC Technologies’
developer program. For more information, please contact DPAC
Technologies.
VCOM Serial Device Driver
The heart of the VCOM software is the VCOM serial device driver (dpacvcom.sys). This
device driver is a fully functional Windows® XP/2000 serial port driver that acts as a buffer
manager, enabling data to pass from an application through the device driver to the NMS. The
VCOM application accesses the device driver through the same standard serial communications
port method used to access the standard serial device driver.
This device driver presents the following interfaces:
ƒ
A standard serial port interface to the Windows® XP/2000 operating system. This
interface standard is known as the VCOM API. All serial port accesses, irrespective of
programming paradigm (C/C++, Visual Basic, etc.), use this interface to access serial
ports. Through this interface a virtual serial port looks like a physical serial port on a
system.
ƒ
A proprietary interface (unique to VCOM) that allows the application control of
serial port functions and the ability to map them to physical IP addresses.

Using VCOM
VCOM Configuration Utility
The VCOM configuration utility is a powerful tool that lets you configure and map physical COM
ports to physical IP addresses. Most users will want to use the VCOM configuration utility in
stand-alone form, as described in this guide.
Other users, such as programmers, value-added resellers, or customers with complex
requirements, may want to consider using the VCOM API to implement custom requirements.
For more information about our developer program and documentation, please contact DPAC
Technologies.
SYSTEM REQUIREMENTS
To install VCOM, you need a computer running Windows® XP Professional or Windows® 2000
connected to a Local Area Network that has an Access Point.
INSTALLING VCOM
The following procedure describes how to install the VCOM driver and VCOM configuration
utility. You perform this installation on the LAN host. Before proceeding, be sure the LAN host
has the application you want to use with VCOM to communicate with the serial client device and
Bridge connected to the serial client.

CHAPTER 6
TROUBLESHOOTING
This chapter provides troubleshooting suggestions you can follow in the unlikely event you
encounter a problem using the AirborneDirect™ Serial Bridge.
TROUBLESHOOTING SUGGESTIONS
The Bridge cannot find the Access
Point.
Verify that the Link LED is solid green. If it isn’t,
refer to “LED Troubleshooting” on the next page.
The Access Point cannot find the
Bridge.
Click the Refresh button in your Access Point’s
configuration application.
If the problem remains, check the Bridge’s physical
connections. Then power-down the Bridge, power it
up, and check the power-up LED sequence
described under “Verifying Your Connections” on
page 25.
Make sure that there is not another AP in the area
that may be interfering with your AP.
The Bridge may be associated to another AP.
Check the Link LED on the Bridge.
If the problem remains, contact Quatech, Inc.
You cannot access the Bridge’s
configuration interface via the ACC.
You may have typed the wrong IP address.
The Bridge cannot associate with an
Access Point.
Change the location of the Bridge to improve
reception.
If you typed the correct IP address, your computer
may be on a different subnet than the Bridge. Be
sure the computer and Bridge are on the same
subnet of the same network.
If that does not help, launch the ACC, go to the
Network Settings Page, and be sure the SSID
matches that of the Access Point (remember the
SSID is case sensitive).

Troubleshooting
After changing the Bridge’s static
IP address, the ACC stops
responding.
Once the static IP address is changed and you click
Save, the Bridge switches to the new IP address and
loses connection with the ACC. To resolve this

Power LED is Amber.
Bridge has not established an IP address either
through DHCP or Static methods.
DHCP is the default method by which the unit
obtains an IP address. Your network must have a
DHCP server available when the bridge is poweredup. Most AP/Routers have a DHCP server built-in.
Enable your DHCP server and re-start the module.
Link LED continues to Blink Red.
Bridge has not found an Access Point with which to
associate. Be sure the Access Point you want to
use is turned on and has WEP and WPA disabled
(you can enable WEP or WPA after the Bridge has
been configured).
If this does not help, be sure there are no nearby
devices causing interference. If there are, either turn
off or move the device causing the interference or
move the Bridge and Access Point to another
location.
Comm LED is Off or Amber.
Be sure a serial device is connected to the Bridge
and that the device is turned on.
Comm LED is Red and Link LED is

APPENDIX A
UDP AND POWER MANAGEMENT
UDP INTERACTION
The Module includes UDP support. There are two configuration options to activate UDP. UDP
transmit can be enabled either in a “UDP” only or “both” mode.
The UDP Target IP Address, UDP Target IP Port, UDP Transmit Mode, and
UDP Listen Port settings apply to UDP functions for the Bridge.
UDP Only Mode
The factory default UDP transmit and receive port number is 8023. You can change this default
value using the settings UDP Target Port and UDP Listen Port.
UDP frames will be passed to the UDP Target IP Address and UDP Target Port
address and/or broadcasted if UDP Transmit Mode is set to bcast or both, when the unit is
in PASS mode. In addition, UDP frames will be received on the UDP Listen Port when the
unit is in PASS mode.
Both Mode
A connection must be made using the TCP tunnel. UDP will transmit and receive
UDP frames (like in UDP only mode) when the TCP tunnel is established and
active. When the TCP connection closes, UDP operations halt. If the TCP tunnel
is active, thereby allocating the serial port, then received UDP datagrams will be
dropped.
HOST INTERACTION USING UDP
The UDP functions (between the Bridge and the Host) operate in pass-through mode. By factory
default, the Module starts up in master-Listen mode.
100-8006-152G
AirborneDirect™ Serial Bridge User’s Guide
Quatech, Inc. Confidential
Page 75
UDP and Power Management
Pass-Through Mode
If the Module has been set to start up in pass-through mode, or is directed into pass-through
mode using the CLI command pass, it will transmit to the UDP target last defined with the
UDP Target IP Address and UDP Target Port settings.
The UDP functions must be enabled via the CLI commands Outbound Transmit
Mode and UDP Transmit Mode.
The configuration must be saved to write the UDP settings to non-volatile memory and the
bridge restarted for the setting to have effect.
ƒ
When the Host sets the Bridge for pass-through mode:
ƒ The Serial Default field set to pass causes the Module to transmit data to the
UDP Target IP Address and UDP Target Port target. The module will also
broadcast the data if the UDP Transmit Mode is set to bcast or both.
ƒ
All data received on the serial port from the Host is sent to the UDP Target IP
Address and UDP Target Port target as UDP payload.
ƒ
All data received from the LAN on the UDP Listen Port is delivered to the Host
on the serial interface.
Detecting and Executing the Escape Sequence
If the Module detects and executes the escape sequence from the Host:
ƒ The escape sequence is transmitted to the LAN application.
ƒ
The Module sends an OK response to the Host.
ƒ
The Host becomes the owner of the serial interface.
ƒ
The Module processes data received from the Host as CLI commands.
Using Pass-Through Mode
The UDP functions are kept active until the Host breaks PASS mode.

UDP and Power Management
POWER MANAGEMENT MODES — UART MODEL ONLY
The Bridge supports several power-management modes that can be used to reduce the
average current consumption. Use the CLI command pm-mode to change the powermanagement settings. summarizes the different settings and their affect.

The IEEE 802.11b standard dictates that the AP can reject requests for Low Power operation,
and require the Module to operate in the active mode. The actual current consumption depends
on the AP and its low-power support implementation.
Transitions into the Sleep and Off modes are allowed under control of the Serial Host. Snooze
is intended for network-initiated activity and waking after a UART Break is received. The Module
automatically transitions back to Snooze after 60-to-120 seconds of inactivity. After waking on
receipt of a radio packet, the Module transitions back to Snooze immediately after the processor
idles.
When in Sleep mode, the Module automatically transitions back to Sleep after 60-to-120
seconds of inactivity following waking on UART activity or Radio Transmit.
From the Off mode, the Module goes to the Active state after receiving a UART Break.
It remains in the Active state until the CLI command pm-mode off is issued.

APPENDIX B
CABLE REPLACEMENT
The following tables outline the steps to set-up a wireless cable replacement connection
between two serial ports, using the Airborne products. This connection relies upon a type of
peer-to-peer wireless network call an Ad Hoc. This network type does not require an Access
Point. The setup is written using Command Line Interface (CLI) commands but can just as
easily be set up via the Bridge’s configuration pages. Please see the CLI Reference Guide for a
full description of the commands.

As long as the slave device is on and is waiting for the connection, the master will boot and
establish a TCP/IP connection with the slave. The slave will accept the connection and a serialto-serial data tunnel will be established between the two units. Once the tunnel is established
data can be sent between the two devices.

Cable Replacement
INFRASTRUCTURE NETWORK CONSIDERATIONS
If you want to use Infrastructure mode, there are a couple of modifications:
• The SSID must match the AP you want to you (step 1 in Table 14& Table 15)
• Leave the network type as Infrastructure (step 2 in Table 14& Table 15).
If you are using static IP addresses no further changes are required to the set-up. If not, you will
need to do a couple of things:
•
•
Enable DHCP (default).
Find out the IP address assigned to the slave unit by the DHCP server. To do this you
can look at the wireless routers attached devices table, search for the device using the
Airborne Control Center (ACC) or guess (if the device has been on the network before in
all likelihood the DHCP server has assigned it the same IP address).
Once you have found the IP address this needs to be used in the Primary LAN Server IP field
(step 7 in Table 15).
Again as long as the Slave is on and associated with the AP, the devices will establish a TCP/IP
connection and bridge data between the serial ports.

APPENDIX E
ASLIP PROTOCOL
TRANSMISSION OF IP DATAGRAMS OVER SERIAL USING
AIRBORNEDIRECT™ SERIAL
Introduction
ASLIP (Airborne Serial Line IP) is a simple packet framing protocol: ASLIP defines a sequence
of characters that frame IP packets on a serial line, and nothing more. It provides no
addressing, packet type identification, error detection/correction or compression mechanisms.
Because the protocol does so little, though, it is usually very easy to implement.
Protocol
The proposed ASLIP protocol defines four special characters:
Character
Definition
START
0xC1 (decimal 193)
END
0xC0 (decimal 192)
ESC
0xDB (decimal 219)
•
Each data packet sent will begin with the START character.
•
Each data packet sent will end with the END character.
•
The ESC character is inserted by the transmitter to indicate that the following byte is a
literal data byte. The receiver removes the ESC character and passes the following byte
as data without interpretation.
•
If the data packet contains a character the same as the END character a two-byte
sequence of ESC and END is sent instead.
•
If the data packet contains a character the same as the START character a two-byte
sequence of ESC and START is sent instead.
•
If the data packet contains a character the same as the ESC character a two-byte
sequence of ESC and ESC is sent instead.
•
ASLIP is applicable only in data pass-through mode.
•
If the data packet contains a START character between a START and END sequence, it
will be treated as an END START sequence i.e. all data preceding the START will be
sent as a data packet and a new data packet will be started.

ASLIP Protocol
Packet Transfer
Each datagram received across the serial line will be sent as a separate IP packet from the
wireless interface.
Each IP packet received on the wireless interface will be identified as a separate datagram,
using the above protocol across the serial interface.
Platform
The above protocol will be implemented on the Airborne UART v4 WPA only firmware platform.
It will be designed to be portable to the Airborne UART 802.11g product.

GLOSSARY
This appendix provides a glossary of wireless terminology.
802.11
The wireless standards developed by the IEEE that specify an "over-the-air"
interface for wireless Local Area Networks. 802.11 is composed of several
standards operating in different radio frequencies.
802.11b
802.11b is the international standard for wireless networking that operates in
the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a
throughput of up to 11 Mbps.
802.11g
802.11g is the international standard for wireless networking that operates in
the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a
throughput of up to 54 Mbps.
Access Point
An interface between a wireless network and a wired network. Access Points
can combine with a distribution system (such as Ethernet) to create multiple
radio cells (BSSs) that enable roaming throughout a facility.
Ad Hoc mode
A wireless network composed of only stations and no Access Point.
Association service
An IEEE 802.11 service that enables the mapping of a wireless station to the
distribution system via an Access Point.
Asynchronous
transmission
A type of synchronization where there is no defined time relationship between
the transmission of frames.
Authentication
The process a station uses to announce its identify to another station.
IEEE 802.11 specifies two forms of authentication: open system and shared
key.
Bandwidth
The amount of transmission capacity available on a network at any point in
time. Available bandwidth depends on several variables such as the rate of
data transmission speed between networked devices, network overhead,
number of users, and the type of device used to connect PCs to a network.
Basic Service Set
(BSS)
A set of 802.11-compliant stations that operate as a connected wireless
network.
Bits per second
(bps)
A measurement of data transmission speed over communication lines based
on the number of bits that can be sent or received per second.
BSSID
Basic Service Set Identifier. A 48-bit identifier used by all stations in a BSS in
frame headers. Usually a MAC address.
Clear channel
assessment
A function that determines the state of the wireless medium in an IEEE
802.11 network.
Client
Any computer connected to a network that requests services (files, print
capability) from another member of the network.
Direct Sequence
Spread Spectrum
(DSSS)
Combines a data signal at the sending station with a higher data rate bit
sequence, which many refer to as a “chip sequence” (also known as
“processing gain”). A high processing gain increases the signal’s resistance
to interference. The minimum processing gain that the FCC allows is 10, and
most products operate under 20.

Glossary
Disassociation
service
An IEEE 802.11 term that defines the process a station or Access Point uses
to notify that it is terminating an existing association.
Distribution service
An IEEE 802.11 station uses the distribution service to send MAC frames
across a distribution system.
GPIO
General Purpose Input/Output refers to the digital I/O lines.
Hot spot
Same as an Access Point, usually found in public areas such as coffee shops
and airports.
IEEE
Institute of Electrical and Electronic Engineers, an international organization
that develops standards for electrical technologies. The organization uses a
series of numbers, like the Dewey Decimal system in libraries, to differentiate
between the various technology families.
Independent Basic
Service Set Network
(IBSS Network)
An IEEE 802.11-based wireless network that has no backbone infrastructure
and consists of at least two wireless stations. This type of network is often
referred to as an “Ad Hoc network” because it can be constructed quickly
without too much planning.
Infrastructure mode
A client setting providing connectivity to an Access Point. As compared to Ad
Hoc mode, whereby PCs communicate directly with each other, clients set in
Infrastructure mode all pass data through a central Access Point. The Access
Point not only mediates wireless network traffic in the immediate
neighborhood, but also provides communication with the wired network. See
Ad Hoc mode and Access Point.
LAN application
A software application that runs on a computer (which is attached to a LAN,
Intranet or the Internet) and using various protocols, can communicate with
the Bridge.
LEAP
Lightweight Extensible Authentication Protocol developed by Cisco. LEAP
provides username/password-based authentication between a wireless client
and a RADIUS server. It is one of several protocols used with the IEEE
802.1X standard for LAN port access control.
Local Area Network
A system of connecting PCs and other devices within the same physical
proximity for sharing resources such as Internet connections, printers, files
and drives. When Wi-Fi is used to connect the devices, the system is known
as a wireless LAN or WLAN.
Media Access
Control (MAC) Layer
One of two sub-layers that make up the Data Link Layer of the OSI reference
model. The MAC layer is responsible for moving data packets to and from
one network node to another across a shared channel.
Peer-to-peer network
A wireless or wired computer network that has no server, central hub or
router. All the networked PCs are equally able to act as a network server or
client, and each client computer can communicate with all the other wireless
computers without having to go through an Access Point or hub. However,
since there is no central base station to monitor traffic or provide Internet
access, the various signals can collide with each other, reducing overall
performance.
RS-232
An EIA standard that specifies up to 20 Kbps, 50 foot, serial transmission
between computers and peripheral devices.
RS-422
An EIA standard that provides a longer transmission distance, but fewer
signal lines, than RS-232. RS-422 uses differential transmission technology
and thus provides high-speed transmission of up to 10 Mbps. The maximum
transmission distance is 1.2 km at a transmission speed of 9600 bps.

Glossary
RS-485
An enhanced version of RS-422. It uses a 2-wire bus topology and is
compatible with the RS-422 interface.
RTOS
An operating system implementing components and services that explicitly
offer deterministic responses, and therefore allow the creation of real-time
systems. An RTOS is characterized by the richness of the services it
provides, the performance characteristics of those services, and the degree
that those performance characteristics can be controlled by the application
engineer (to satisfy the requirements of the application).
Service Set Identifier
(SSID)
An identifier attached to packets sent over the wireless LAN that functions as
a "password" for joining a particular radio network (BSS). All radios and
Access Points within the same BSS must use the same SSID, or their
packets will be ignored.
Telnet
A virtual terminal protocol used in the Internet, enabling users to log into a
remote host.
TKIP
Temporal Key Integrity Protocol and is used in encryption. TKIP is an IEEE
802.11i standard and an enhancement to WEP security.
Transceiver
A device for transmitting and receiving packets between the computer and
the medium.
Transmission
Control Protocol
(TCP)
A commonly used protocol for establishing and maintaining communications
between applications on different computers. TCP provides full-duplex,
acknowledged, and flow-controlled service to upper-layer protocols and
applications.
Wide Area Network
(WAN)
A communication system of connecting PCs (and other computing devices)
across a large local, regional, national, or international geographic area. Also
used to distinguish between phone-based data networks and Wi-Fi. Phone
networks are considered WANs and Wi-Fi networks are considered wireless
LANs.
Wi-Fi
Wi-Fi is a name for 802.11 wireless network technology.
Wi-Fi Alliance
A non-profit international association formed in 1999 to certify interoperability
of wireless LAN products based on the IEEE 802.11 specification.
A security protocol for wireless LANs defined in the IEEE 802.11 standard.
WEP is designed to provide the same level of security as a wired LAN.
Wired Equivalent
Privacy (WEP)
WLAN
Also referred to as a wireless LAN. A type of local area network that uses
high-frequency radio waves rather than wires to communicate between nodes
and provide network connectivity.
WPA
Wi-Fi Protected Access. It addresses all known Wired Equivalent Privacy
(WEP) vulnerabilities. WPA uses RC4 for encryption and TKIP for key
management. It includes a message integrity mechanism commonly called
Michael or MIC.
WPA-LEAP
Wi-Fi Protected Access - Light Extensible Authentication Protocol, an
implementation based on the IEEE 802.11i 2004 and IEEE 802.1X 2001
standards, which includes the LEAP protocol for initial key assignment.
WPA-PSK
Wi-Fi Protected Access - Pre-Shared Key, an implementation based on the
IEEE 802.11i 2004 and IEEE 802.1X 2001 standards, where the PSK is
stored on the client.
