Introduction
The IEEE 802.11 Specifications
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless
devices operating in the 2.4 GHz frequency band. This standard includes provisions for three radio
technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices
that comply with the 802.11 standard operate at a data rate of either 1 or 2 Mbps.
In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can operate at speeds of
up to 11 Mbps. The IEEE ratified this standard as “802.11b.” 802.11b devices are backwards compatible with
2.4 GHz 802.11 devices (that operate at 1 or 2 Mbps).
Also in 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz frequency band.
This standard is referred to as “802.11a.” 802.11a devices are not backwards compatible with 2.4 GHz 802.11 or
802.11b devices. 802.11a radios use a radio technology called Orthogonal Frequency Division Multiplexing
(OFDM) to achieve data rates of up to 54 Mbps.
Since both 802.11a and 802.11b are based on the same common standard (IEEE 802.11), 802.11a and 802.11b
devices have many of the same parameters. This user’s guide uses the generic term 802.11 to refer to
parameters that apply to both 802.11a and 802.11b devices.
In addition to supporting 802.11a and 802.11b mode, the ORiNOCO 802.11a/b Combo CardBus Card supports a
third operating mode: 2XTM mode. 2X mode is an extension of the 802.11a standard that allows data rates of up
to 108 Mbps; the ORiNOCO Utility refers to this mode as 802.11a 2X. Note that 2X mode is not part of the
802.11a standard (so devices in 2X mode are not interoperable with 802.11a devices in Turbo mode from other
vendors), and 2X is not available in all countries.
Note:
An 802.11a device and an 802.11b device cannot communicate with each other. Also, a device in
802.11a 2X mode and a device operating in 802.11a mode (2X disabled) cannot communicate.

Chapter 2
Installation
This chapter describes how to install an ORiNOCO 802.11a/b Combo CardBus Card and software in a computer
running Windows XP, Windows 2000, Windows Millennium Edition (ME) or Windows 98 Second Edition (SE).
Note:
Run the ORiNOCO Installation program before installing the 802.11a/b card in the computer.
Pre-installation Considerations
Review the following pre-installation considerations before installing a 802.11a/b Combo CardBus Card.
U.S. Regulatory Warnings
FCC Guidelines
This device has been tested for compliance with FCC RF Exposure (SAR) limits in a typical laptop configuration
with a PCMCIA slot on either the right or left side of the laptop.
In order to comply with the SAR limit established in the ANSI C95.1 standard, it is recommended when using a
PC card adapter that the integrated antenna is positioned more than 2.5 centimeters from nearby persons
during extended periods of operation. If the antenna is positioned less than 2.5 centimeters from nearby
persons, it is recommended that the user limit exposure time.
This device and its antenna must not be co-located or operated in conjunction with any other antenna or
transmitter.
Radio Frequency Interference Requirements
The ORiNOCO 802.11a/b Combo CardBus Card, Model 8460, operates in multiple frequency ranges including
the 5.15 to 5.35 GHz band (when in 802.11a or 2X mode); the device is restricted to indoor use due to their
operation in the 5.15 to 5.25 GHz frequency range. FCC 15.407(e) requires that these devices be used indoors in
the frequency range of 5.15 to 5.25 GHz to reduce the potential or harmful interference to co-channel Mobile
Satellite systems. Therefore the devices should be used indoor only for channel 36, 40, 44, and 48 and when 2X
mode is enabled, channel 42 and 50.
High power radars are allocated as primary users of the 5.25 to 5.35 GHz and 5.725 to 5.850 GHz band. These
radar stations can cause interference with and/or damage the ORiNOCO 802.11a/b Combo CardBus Card.

Chapter 3
Wireless Topologies
ORiNOCO wireless products look and operate similar to Ethernet products. The only difference is that a radio
replaces the wire between various nodes. This means that all of your existing applications that operate over
Ethernet will work with ORiNOCO without any special wireless networking software. The ORiNOCO 802.11a/b
Combo CardBus Card supports several network topologies, which are described in this chapter.
Ad Hoc
Two or more computers easily establish an ad hoc network when the units are in range of each other. Each
computer can dynamically connect and reconnect to the others with no additional configuration, using
off-the-shelf peer-to-peer network operating systems, as illustrated in Figure 1.
Figure 1 Ad Hoc
The ORiNOCO 802.11a/b Combo CardBus Card can communicate with either an 802.11a or an 802.11b Ad Hoc
network (but it can not dynamically switch between the two). Therefore, you must manually configure the card to
use one radio mode or the other. Follow these steps to configure the card as a member of an Ad Hoc network:
1.
Launch the ORiNOCO Utility and select the Configuration tab.
2. Set Network Type to Ad Hoc.
3.
Select a Mode: if you want the card to join an 802.11a Ad Hoc network, select 802.11a; if you want the card
to join an 802.11b Ad Hoc network, select 802.11b. You cannot use the Auto option when Network Type is
set to Ad Hoc.
Note:
802.11a products sold in Europe do not support Ad Hoc mode.
4.
Set the card’s SSID to match the SSID used by the Ad Hoc network.
5.
Select the Advanced tab.
6. Select the Channel used by the Ad Hoc network.
7.
Click Apply or OK to save these changes.
Note:
See Chapter 4 for additional information on the ORiNOCO Utility and these parameters.
Wireless Topologies
14
Infrastructure
Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that
capability to wireless nodes. This is accomplished by installing one or more Access Points on the Ethernet
network. You can also add a Harmony Access Point Controller to the network to simplify Access Point
management and take advantage of additional features. See the Harmony Access Point Controller User’s Guide
for more information.
Connecting to a Single AP
Figure 2 depicts an ORiNOCO network that uses a single Access Point (AP); in this example, the Access Point is
an 802.11a AP.
Figure 2 Single 802.11a AP
Wireless Topologies
15
Roaming Between Multiple APs
For larger environments, the ORiNOCO 802.11a/b Combo Card may roam from one Access Point to another while
maintaining the same network connection. The Access Points establish coverage areas or cells similar in
concept to those of a cellular phone network. The card will connect to any Access Point that is within range.
The ORiNOCO 802.11a/b Combo Card supports roaming between APs of the same type (for example, from one
802.11a AP to another) or roaming between APs of different types (from one 802.11a AP to an 802.11b AP).
Figure 3 illustrates roaming between APs of the same radio type.
Figure 3 Roaming Between APs of the Same Radio Type
Wireless Topologies
16
Figure 4 illustrates roaming between APs of different radio types.
Figure 4: Roaming Between APs of Different Radio Types
In either case, each Access Point within a roaming network must have a unique, independent Channel, but all
must have the same SSID and security settings (if applicable).
Mobile clients equipped with an 802.11a/802.11b card are configured to operate in Infrastructure mode and
have the same SSID and security settings as the Access Points. Alternatively, the mobile client may use an SSID
of “any” to associate with any available Access Point, regardless of the Access Point’s SSID.
As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved. The user can
move freely between the Access Points in the network. When the roaming client leaves the transmission range
of one Access Point, the card automatically detects the other Access Point(s) in the same vicinity to continue the
network connection.
Note:
The Access Points’ cells must overlap to ensure that there are no gaps in coverage so that the roaming
client will always have a connection available.
See Figures 3 and 4 for an example of roaming Infrastructure networks. In addition, if your network has a
Harmony Access Point Controllers, you can install ORiNOCO Access Points on different IP subnets from the
AP Controller, allowing mobile users to roam across routers. For more information on the Harmony AP Controller
and Access Points, refer to the Harmony Access Point Controller User’s Guide.

Guidelines for Roaming
•
an ORiNOCO 802.11a/b Combo CardBus Card can roam between multiple 802.11a Access Points, multiple
802.11b Access Points, or between both 802.11a and 802.11b Access Points.
•
To support roaming between 802.11a and 802.11b Access Points, the Combo CardBus Card’s Mode must be
set to Auto.
•
Standard 802.11a clients can only roam between 802.11a Access Points.
•
Standard 802.11b clients can only roam between 802.11b Access Points.
•
All 802.11a or 802.11b Access Points that a client will roam between must have the same SSID.
•
All workstations with Combo CardBus Cards installed must use either an SSID of “any” or the same SSID as
the Access Points that they will roam between.
•
All Access Points and Combo CardBus Cards must have the same security settings to communicate.
•
The Access Points’ cells must overlap to ensure that there are no gaps in coverage and to ensure that the
roaming client will always have a connection available.
•
Access Points in the same vicinity should each use a unique, independent Channel to avoid potential interference.
•
Access Points that use the same Channel should be installed as far away from each other as possible to
reduce potential interference.

The ORiNOCO Utility includes several tools for diagnostic and configuration purposes. Each of the utility’s
screens is described below. For additional information about the ORiNOCO Utility, click Help on any screen to
view on-line Help documentation.
Association Information
The Association Information screen, shown below, displays information about the card’s connection with a
wireless network.
The Association Information screen reports the following statistics:
•
Mode: This field reports whether the card is in 802.11a mode or 802.11b mode.
•
Association State: This field reports if the card is communicating with an Access Point (AP) or Ad Hoc network. When communicating with an AP, this field reports “ASSOCIATED AP” and displays the AP’s physical
address. When communicating with an Ad Hoc network, this field displays “JOINED AD HOC MODE.” If no AP
or Ad Hoc network is found, this field displays “NOT JOINED.”
•
Channel (Freq): This field displays the current Channel and center frequency that the card is using.
Configuration & the ORiNOCO Utility

•
Security: Reports the type of security that the card is using. Options include “No Security enabled (or
802.1x Security)”, “WEP Security”, and the “Harmony Security Protocol”. If using the Harmony Security Protocol, this field also reports the protocol’s status: “Not Authenticated,” “User Not Logged In,” “User Associated,” and “User is using Unique Encryption Key” (with time of login).
•
Signal Strength: The Signal bar displays the signal strength for the last packet received by the card. Signal
strength is reported in decibels (dB). The color-coded chart below the Signal bar indicates the relative
strength of the signal: a signal in the red or orange section indicates a weak connection; a signal in the yellow or light green section indicates a good connection; a signal in the darker green section indicates an
excellent connection.
•
Instantaneous Packets/Sec Sent: This statistic displays the current rate at which the card is transmitting
packets to another 802.11a or 802.11b device. This information is represented as the number of packets
sent per second by the card and is plotted on the graph located below the Packets/sec field. Note that this

Configuration
Click the Configuration tab to view the Station Configuration screen.
This screen contains three configuration tabs: Basic, Security, and Advanced. In addition, you can also create,
edit, and switch between user profiles from this screen. After you have made one or more changes to the
configuration settings, click Apply or OK to save the changes. All of these parameters apply to the card
regardless of whether it is in 802.11a mode or 802.11b mode, unless otherwise stated.
Basic
The Basic configuration screen is shown on the next page. You can configure the following parameters:
Network Type
Network Type configures an ORiNOCO 802.11a/b Combo CardBus Card to operate in either Ad Hoc mode or
Infrastructure mode.
When set to Ad Hoc, all 802.11a or 802.11b devices must have the same SSID, Channel, and WEP Keys (if WEP is
enabled) to communicate. An Ad Hoc network is a wireless network that consists of only wireless client adapters
(i.e., a network that does not have an Access Point). If you set Network Type to Ad Hoc, then you must also
select a Mode (802.11a or 802.11b) of operation. The card cannot operate in Auto mode when set to Ad Hoc.
Note:
802.11a products sold in Europe do not support Ad Hoc mode.
When set to Infrastructure, an 802.11a or 802.11b client must have the same SSID and security settings as the
Access Points on the network to communicate. An Infrastructure network is any network that includes one or
more 802.11a or 802.11b Access Points. By default, the Combo CardBus Card operates in Infrastructure.
Configuration & the ORiNOCO Utility
21
Mode
Mode configures the ORiNOCO 802.11a/b Combo CardBus Card to operate in 802.11a, 802.11b, or Auto mode.
In 802.11a mode, the card complies with the IEEE 802.11a standard and provides data rates of up to 54 Mbps. In
addition, the card will automatically detect if an Access Point is operating in 2X mode and automatically
switches to 2X mode as necessary. (2X mode provides data rates of up to 108 Mbps.)
In 802.11b mode, the card complies with the IEEE 802.11b standard and provides data rates of up to 11 Mbps.
In Auto mode, the card can automatically switch between 802.11a and 802.11b modes based on the signals it
receives from Access Points in its vicinity. If you set the card to Auto, you should also configure Auto Mode
Preference.
Note:
If you want the card to join an Ad Hoc network, you must manually configure the card to either 802.11a
or 802.11b mode.
Auto Mode Preference
If you set Mode to Auto, you should also configure Auto Mode Preference. This parameter determines which
type of network the card will search for first. Also, if the card receives signals from both an 802.11a AP and an
802.11b AP, the card will choose which AP to associate with based on this setting. Select 802.11a from the
drop-down list if you want the card to choose 802.11a networks over 802.11b networks. Select 802.11b from the
drop-down list if you want the card to choose 802.11b networks over 802.11a networks.
Configuration & the ORiNOCO Utility
22
Power Saving
The ORiNOCO 802.11a/b Combo CardBus Card supports optional power management to conserve battery life.
When Power Saving Mode is set to Normal or Maximum, the card enters a “doze” mode where it becomes
inactive and only wakes up periodically to receive control messages from the Access Point. The card wakes up
more often in Normal mode than in Maximum mode so a card in Normal mode will respond sooner to network
requests than a node in Maximum mode. However, Maximum mode draws less power than Normal mode.
When an Access Point receives a packet destined for a dozing client, it buffers the packet and includes a
notification within its control message to alert the client that a packet is waiting for it. Once the card receives the
control message, it polls the Access Point to request that the buffered packet be sent to it.
When set to Off, the card does not use the Power Saving mechanism.
Roaming
The Roaming parameter allows you to determine how tolerant the Combo CardBus Card is to radio phenomena
that can cause the unit to roam from one Access Point to another in order to maintain a strong wireless
connection.
In areas with many Access Points that provide heavy overlapping coverage, set this parameter to Fast to
maintain high throughput for each wireless adapter.
In most networks, set Roaming to Normal. Wireless adapter throughput will not change noticeably, and an
overabundance of Access Points is not required.
If the coverage area provided by Access Points is sparse, set Roaming to Slow. The card will not roam until it is
nearly out of range of the Access Point with which it is associated.
SSID
The SSID (Service Set ID), which is also referred to as the ESSID (Extended Service Set ID), is a text string that all
members of the same 802.11 network share.
The SSID may be up to 32 alphanumeric characters long, including spaces. Also, when configured to “any,” a
Combo CardBus Card can communicate with any available Access Point regardless of the Access Point’s SSID.
In an Infrastructure network, the SSID must match on all Harmony Access Points and clients (unless a client’s
SSID is “any”). Devices that do not share the same SSID cannot communicate.
In an Ad Hoc network without an Access Point, each 802.11 device must have the same SSID to participate in the
network. A node cannot use the “any” SSID to join an Ad Hoc network.
By default, the card’s SSID is set to “any”.
Security
The ORiNOCO 802.11a/b Combo CardBus Card offers four security options: No Security, Use WEP for
Authentication and Encryption, Use the Harmony Security Protocol, and 802.1x.
The Security configuration screen is shown on the next page. You can configure the following parameters:
WEP Encryption and Authentication
The IEEE 802.11 standards specify an optional encryption feature, known as Wired Equivalent Privacy or WEP,
that is designed to provide a wireless LAN with a security level equal to what is found on a wired Ethernet
network. WEP encrypts the data portion of each packet exchanged on an 802.11 network using a 64-bit, 128-bit,
or 152-bit encryption key (also known as a WEP Key).
Note:
152-bit encryption is only available in 802.11a mode.
In addition, the card uses WEP with Shared Key Authentication to prevent unauthorized devices from
associating with the 802.11 network.
Configuration & the ORiNOCO Utility
23
When WEP is enabled, two 802.11 devices must have the same WEP Keys and both devices must be configured
to support WEP in order to communicate. If one device is configured to use WEP for Authentication and
Encryption but a second device is not, then the two devices will not communicate, even if both devices have the
same WEP Keys.
The ORiNOCO 802.11a/b Combo CardBus Card can support up to four WEP Keys (all four Keys must have the
same Key Size). The card can decrypt information that was encrypted with any of its four WEP Keys, but it will
only use the Default Key to encrypt outgoing information.
For 64-bit encryption, a WEP Key is 10 hexadecimal digits (0-9 and A-F); for 128-bit encryption, a WEP Key is 26
hexadecimal digits (0-9 and A-F); and for 152-bit encryption, a WEP Key is 32 hexadecimal digits (0-9 and A-F).
Note:
When WEP is enabled, Proxim recommends that you configure all 802.11 devices in the Extended Service Set with the same WEP Keys in the same order (but the devices do not need to use the same
default Key).
Follow these steps to enable WEP for Authentication and Encryption:
1.
Select Use WEP for Authentication and Encryption from the Security Level box.
2. Click Configure WEP Keys.
3.
Select a Key Size from the drop-down menu (64 Bit, 128 Bit, or 152 Bit).
Configuration & the ORiNOCO Utility
24
4.
Enter one to four WEP Keys in the fields provided, as shown below.
5.
Use only hexadecimal digits (i.e., 0-9 and A-F). For 64-bit encryption, enter 10 digits for each Key; for 128-bit
encryption, enter 26 digits for each Key; for 152-bit encryption, enter 32 digits for each Key.
Note:
If you created a text file that contains the WEP Keys, click Read Keys to upload those Keys to the card.
See “Read Key File Format” on page 24 for formatting information.
6. Click OK to save the WEP Keys.
7.
Select one of the Keys you configured as the Default Key.
8. Click Apply or OK to save the new WEP settings.
9. If you need to change a WEP Key at a later date, click Configure WEP Keys and enter one to four new WEP
Keys. Note that any Keys you entered previously will not be visible (stars appear in place of the digits).
Read Key File Format
If you have multiple clients to configure, you can avoid having to enter each WEP Key manually by creating a text
file that contains the Keys. Once you have the text file, you can upload the Keys to a client by clicking the Read
Keys button found on the WEP Keys Configuration screen.
To create the text file, use a text program such as Microsoft Notepad or WordPad. The text file should have a
“.txt” extension. The first line of the text file must read “[WEP_KEY_VALUE]”. Then, enter one to four Keys in the
following format: “key#=”, where # indicates the Key number (1-4) and  is the specified
Key’s hexadecimal digits.
Each Key must be contain hexadecimal digits only (0-9 and A-F), and you must use the same number of digits
for each Key. The number of digits depends upon the Key Size you select in the WEP Keys Configuration screen:
• For 64 Bit, use 10 digits per Key.
• For 128 Bit, use 26 digits per Key.
• For 152 Bit, use 32 digits per Key.
Configuration & the ORiNOCO Utility
25
The following example illustrates the WEP Key file format for 64-bit encryption:
[WEP_KEY_VALUE]
key1=1234567890
key2=0987654321
key3=ABCDEF1234
key4=ABCDEFABCD
Harmony Security Protocol
The Harmony Security Protocol automates encryption management, assigning a unique and dynamic WEP Key
to each user. The Harmony Security Protocol includes the following features:
•
Uses 152-Bit WEP Encryption
•
Generates a unique WEP Key for each user that is valid only for the current network session
•
Periodically renews the user’s Harmony session and assigns a new WEP Key without requiring any end user
interaction
•
Incorporates the end user’s logon prompt into Microsoft Windows’ standard logon procedure on the client
device
Each Harmony device plays a role in the Harmony Security Protocol: the AP Controllers maintain a database of
user name and passwords to authenticate users; the Access Points block all network traffic to or from a client
until after the user has been successfully authenticated by the Harmony System; and the Harmony client
adapters include a software utility that incorporates the Harmony logon prompt into the standard Windows
logon procedure.
When the Harmony Security Protocol is enabled on a client adapter, the user is prompted to enter his or her
Harmony User Name and Password during boot up, either immediately before or after the Windows logon
prompt (depending on the device configuration).
Once the user has been authenticated by the Harmony System, the wireless client receives a unique 152-bit
WEP Key from the Harmony System, and it can begin to exchange data with the Ethernet network. Refer to the
Harmony Access Point Controller User’s Guide for more information on the Harmony Security Protocol.
Harmony Security Protocol Guidelines
If you want to use the Harmony Security Protocol on your network, you must enable the protocol on all of
your network’s Harmony Access Points and clients.
•
•
At this time, the Harmony Security Protocol’s client application supports Windows 98 SE, ME, 2000 Professional, and XP. The protocol does not support Windows 2000 Server or NT 4.0.
•
The Harmony Security Protocol is only available for clients that are operating in Infrastructure mode.
•
A network administrator who manages the network’s Harmony Access Point Controller(s) must assign each
user a Harmony User Name and Password and enter this information into the Harmony System’s User Database. Refer to the Harmony Access Point Controller User’s Guide for details.
•
If you enable the Harmony Security Protocol, you do not need to configure WEP Keys on a wireless client
(the Harmony System will generate keys for you).
Follow these steps to enable the Harmony Security Protocol:
1.
Select Use Harmony Security Protocol within the Security Level box.
2. Place a check mark in the Log on to Harmony Security before Windows Logon box if you want to connect to
the wireless network before logging on to the Windows operating system.
Note:
3.
You should enable the Log on to Harmony Security before Windows Logon option if your computer connects to a Windows Domain Controller, connects to a Novell network, automatically reconnects to
shared network drives during Windows logon, or runs networking software (e.g., PC Anywhere) before
connecting to the network.
Click Apply or OK to save the new security settings.

802.1x
802.1x is an IEEE security standard for authenticating users on local area networks based on the Extensible
Authentication Protocol (EAP). For more information on this standard, refer to the IEEE Web site at
http://www.ieee.org/.
On a wireless LAN with 802.1x enabled, an Access Point will block all traffic from a wireless client until after the
user has been authenticated by the network’s RADIUS (Remote Authentication Dial-In User Service) server.
Proxim supports the following RADIUS servers for use with Harmony products:
• Microsoft Windows 2000 Internet Authentication Service (IAS) Server
• Funk Odyssey Server
Note:
You may also need to install additional components based upon the server’s requirements and EAP
authentication type. For example, EAP-TLS requires a Certificate Authority (CA) and that digital certificates be installed on the RADIUS server and each wireless device.
Configuration & the ORiNOCO Utility
28
EAP is a flexible protocol which does not specify an authentication type. The available authentication types will
vary based upon your RADIUS server and your client software; many offer advanced features such as mutual
authentication between client and server and data encryption. For data encryption, a RADIUS server generates a
unique WEP Key for each user following authentication. This WEP Key is used to encrypt unicast packets
between the Access Point and wireless client. To encrypt broadcast packets, the Access Point and its clients use
the AP’s configured Global WEP Keys.
The ORiNOCO Utility does not include configuration settings for 802.1x. To enable 802.1x support and configure
802.1x settings (like EAP authentication type), you need to use a client utility provided by a RADIUS server
manufacturer, like Microsoft or Funk Software. Refer to Microsoft’s (http://www.microsoft.com/) and Funk
Software’s (http://www.funk.com/) Web sites or the documentation that came with your 802.1x solution for
details.
Note:
Confirm that the ORiNOCO Utility’s Security Level is set to No Security before enabling 802.1x support
using a third-party client utility.
As of the release of this user’s guide, Microsoft provides 802.1x support for Windows XP users only as part of
the operating system. To enable 802.1x on a Windows XP computer, you need to disable the ORiNOCO
Configuration options.

Advanced
The Advanced configuration screen is shown below.
You can configure the following parameters:
Channel
In a wireless network, the Channel specifies the range of frequencies that the network members use to
communicate. 802.11a and 802.11b devices both communicate by spreading a radio signal over a range of
frequencies, but they operate at different frequencies and employ different communication techniques. 802.11a
devices operate in the 5 GHz band; 802.11b devices operate in the 2.4 GHz band.
When the card’s Network Type is set to Infrastructure, it automatically receives a Channel assignment from its
Access Point (the AP can be using either 802.11a or 802.11b). Therefore, Channel is not a configurable
parameter when the card is in Infrastructure mode.
When the card’s Network Type is set to Ad Hoc, you must manually set the Channel the card will use. This
should be the same Channel as the other Ad Hoc devices are using. To set the Channel, click the Advanced
configuration tab and select a Channel number from the Channel drop-down menu. The list of available
Channels will vary depending on the card’s operating mode (802.11a or 802.11b).
Note:
Auto mode is not available when the card’s Network Type is Ad Hoc. You must force the card to operate
in either 802.11a or 802.11b mode.
Configuration & the ORiNOCO Utility
31
The available Channels associated with each mode are listed below.
802.11a
The IEEE 802.11a specification allocates the available frequencies in the 5 GHz band into a series of operating
Channels that are identified by a Channel number and a center carrier frequency.
The number of available Channels varies by region.
For United States and Canada: The ORiNOCO 802.11a/b Combo CardBus Card can use one of thirteen Channels
in 802.11a-compliant mode: Channel 36 (5.18 GHz), Channel 40 (5.20 GHz), Channel 44 (5.22 GHz), Channel 48
(5.24 GHz), Channel 52 (5.26 GHz), Channel 56 (5.28 GHz), Channel 60 (5.30 GHz), Channel 64 (5.32 GHz),
Channel 149 (5.745 GHz), Channel 153 (5.765 GHz), Channel 157 (5.785 GHz), Channel 161 (5.805 GHz), and
Channel 165 (5.825 GHz). When the card is operating in the optional 2X mode, it can use one of five Channels:
Channel 42 (5.21 GHz), Channel 50 (5.25 GHz), Channel 58 (5.29 GHz), Channel 152 (5.760 GHz), and Channel
160 (5.800 GHz). If you wish to install multiple Ad Hoc networks in the same vicinity, configure each network
with a unique Channel to avoid interference between networks. Keep in mind that each Channel in 2X mode
overlaps multiple Channels in 802.11a mode. For example, if an Infrastructure network in 2X mode is using
Channel 50, do not configure nearby Ad Hoc networks in 802.11a mode for Channel 42, 48, 52, or 56.
Note:
See “Radio Frequency Interference Requirements” on page 9 for important regulatory information concerning Channel selection.
For Europe: The ORiNOCO 802.11a/b Combo CardBus Card can use one of nineteen Channels: Channel 36
(5.18 GHz), Channel 40 (5.20 GHz), Channel 44 (5.22 GHz), Channel 48 (5.24 GHz), Channel 52 (5.26 GHz),
Channel 56 (5.28 GHz), Channel 60 (5.30 GHz), Channel 64 (5.32 GHz), Channel 100 (5.500 GHz), Channel 104
(5.520 GHz), Channel 108 (5.540 GHz), Channel 112 (5.560 GHz), Channel 116 (5.580 GHz), Channel 120 (5.600
GHz), Channel 124 (5.620 GHz), Channel 128 (5.640 GHz), Channel 132 (5.660 GHz), Channel 136 (5.680 GHz),
and Channel 140 (5.700 GHz).
For Japan: The ORiNOCO 802.11a/b Combo CardBus Card can use one of four Channels: Channel 34 (5.17 GHz),
Channel 38 (5.19 GHz), Channel 42 (5.21 GHz), and Channel 46 (5.23 GHz). If you wish to install multiple Ad Hoc
networks in the same vicinity, Proxim recommends that you configure each network with a unique Channel to
avoid interference between networks.
For Singapore: The ORiNOCO 802.11a/b Combo CardBus Card can use one of four Channels: Channel 36
(5.18 GHz), Channel 40 (5.20 GHz), Channel 44 (5.22 GHz), or Channel 48 (5.24 GHz).
802.11b
The IEEE 802.11b specification allocates the 2.4 GHz frequency band into 14 overlapping operating Channels.
Each Channel corresponds to a different set of frequencies; the center frequency for each of the 14 Channels is
shown in the table below. Two 802.11b Channels must be separated by 25 MHz to be independent of each other
(that is, to not overlap).

Configuration & the ORiNOCO Utility
32
For United States and Canada: The ORiNOCO 802.11a/b Combo CardBus Card can use Channels 1 through 11.
However, only Channels 1, 6, and 11 are independent and do not overlap with each other. If you wish to install
multiple Ad Hoc networks in the same vicinity, Proxim recommends that you install no more than three Ad Hoc
networks in the same location and that you configure each network with a unique independent Channel (1, 6,
or 11) to avoid interference between networks.
For Europe (except France and Spain): The ORiNOCO 802.11a/b Combo CardBus Card can use Channels 1
through 13. However, only Channels 1, 6, and 11 are independent and do not overlap with each other.
For France: The ORiNOCO 802.11a/b Combo CardBus Card can use Channels 10 through 13. All of these
Channels overlap so you must test for interference before installing multiple networks in the same vicinity. For
multi-cell environments, try to use the Channels that are farthest apart for best results (for example, use
Channel 10 for one network and Channel 13 for another).
For Spain: The ORiNOCO 802.11a/b Combo CardBus Card can use Channels 10 and 11.
For Japan: The ORiNOCO 802.11a/b Combo CardBus Card can use Channels 1 through 14. However, only
Channels 1, 6, and 11 are independent and do not overlap with each other.
Send Rate
The Send Rate specifies the data rate at which the ORiNOCO 802.11a/b Combo CardBus Card transmits packets.
There are two Send Rate fields: one under the 802.11a heading and one under the 802.11b heading. The 802.11a
value applies when the card is in 802.11a mode; the 802.11b value applies when the card is in 802.11b mode.
Note:
Forcing the card to operate at a high data rate only will reduce the range of the product.
802.11a
The IEEE 802.11a specification supports eight data rates: 54 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12
Mbps, 9 Mbps, and 6 Mbps. ORiNOCO’s 2X mode supports eight data rates: 108 Mbps, 96 Mbps, 72 Mbps, 48
Mbps, 36 Mbps, 24 Mbps, 18 Mbps, and 12 Mbps.
As the Combo CardBus Card in 802.11a mode travels away from an 802.11a Access Point (when in Infrastructure
mode) or from other 802.11a nodes (when in Ad Hoc mode), the data rate automatically decreases in order to
maintain a usable radio connection. For example, in an Infrastructure network that is using 2X mode, a client
that is close to an Access Point may operate at 108 Mbps, but a client that is far away from the Access Point may
operate at 12 Mbps.
By default, the card automatically adjusts the transmit rate depending on the mode of operation
(802.11a-compliant or 2X). However, you can also manually configure a specific send rate that the card will use.
For example, if you configure the Send Rate to 36 Mbps, the card will transmit only at 36 Mbps.
802.11b
The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps, 2 Mbps, and 1 Mbps. As the Combo
CardBus Card in 802.11b mode travels further and further away from an 802.11b Access Point (in Infrastructure
mode) or from other 802.11b nodes (in Ad Hoc mode), the data rate automatically decreases in order to
maintain a usable radio connection. For example, in an Infrastructure network a client that is close to an Access
Point may operate at 11 Mbps, but a client that is far away from the Access Point may operate at 2 Mbps.
By default, the card automatically adjusts the data rate. However, you can manually configure the card to
operate in 11 Mbps mode only, 5.5 Mbps mode only, 2 Mbps mode only, and 1 Mbps mode only. In addition, to
be compatible with existing 2 Mbps 802.11 solutions, you can configure the PC Card to automatically switch
between 2 Mbps and 1 Mbps as necessary. For example, if your application requires that the card maintain an
11 Mbps data rate, you can configure it to send packets at 11 Mbps only.

RTS/CTS
The 802.11 standard supports optional RTS/CTS communication based on packet size. Without RTS/CTS, a
sending radio listens to see if another radio is already using the medium before transmitting a data packet. If
the medium is free, the sending radio transmits its packets. However, there is no guarantee that another radio is
not transmitting a packet at the same time, causing a collision.
When RTS/CTS occurs, the sending radio first transmits a Request to Send (RTS) packet to confirm that the
medium is clear. When the receiving radio successfully receives the RTS packet, it transmits back a Clear to
Send (CTS) packet to the sending radio. When the sending radio receives the CTS packet, it sends the data
packet to the receiving radio. The RTS and CTS packets contain a reservation time to notify other radios that the
medium is in use for a specified period. This helps to minimize collisions.
While RTS/CTS adds overhead to the radio network, it is particularly useful for large packets that take longer to
resend after a collision occurs.
There are two RTS/CTS fields: one under the 802.11a heading and one under the 802.11b heading. The 802.11a
value applies when the card is in 802.11a mode; the 802.11b value applies when the card is in 802.11b mode.
For both 802.11a and 802.11b modes, you may configure the ORiNOCO 802.11a/b Combo CardBus Card to never
use RTS/CTS (i.e., disable RTS/CTS) or to use RTS/CTS for packets over a certain size. For example, if the
RTS/CTS Threshold is set to 1000 Bytes, then a sending radio will use RTS/CTS before transmitting any packet
1000 Bytes or larger.
The RTS/CTS Threshold supports a range between 256 and 2345 Bytes for both 802.11a mode and 802.11b
mode. If set to 256, then a sending radio will use RTS/CTS before transmitting all packets 256 Bytes or larger. If
set to 2345, then a sending radio will fragment only those radio packets that are 2345 Bytes or larger.
Fragmentation
The ORiNOCO 802.11a/b CardBus Card supports an optional feature called Fragmentation. In harsh radio
environments, wireless devices may have difficulty transmitting large packets that exceed a certain size.
However, when Fragmentation is enabled, a wireless device can break up large packets into a number of smaller
packets (called “fragments”) that can be successfully transmitted to another wireless device. The receiving
device then reassembles the original packet once it has received all of the fragments.
There are Fragmentation fields: one under the 802.11a heading and one under the 802.11b heading. The
802.11a value applies when the card is in 802.11a mode; the 802.11b value applies when the card is in 802.11b
mode.
For both 802.11a and 802.11b modes, you may configure the ORiNOCO 802.11a/b Combo CardBus Card to never
use Fragmentation or to fragment only those packets that exceed a certain size. For example, if the
Fragmentation Threshold is set to 1000 Bytes, then a sending radio will fragment any packet 1000 Bytes or
larger before transmitting.
The Fragmentation Threshold supports a range between 256 and 2345 Bytes for both 802.11a mode and 802.11b
mode. If set to 256, then a sending radio will fragment all packets 256 Bytes or larger. If set to 2345, then a
sending radio will fragment only those radio packets that are 2345 Bytes or larger.
Profiles
If you use the ORiNOCO 802.11a/b Combo CardBus Card in a laptop computer that moves between several
wireless networks, you can create an individual profile for each network to simplify configuration. For example,
if you have an 802.11a network at the office and an 802.11b network at home, you can use the same laptop on
both networks and switch between the each network’s unique configuration settings with a click of a button.
The Switch to Profile box appears at the bottom of the Station Configuration screen. The Profile List box reports
the current profile in use. Any configuration changes that you apply are saved to the current profile. To switch to
another profile, select it from the Profile List drop-down menu and click Switch. You can also switch profiles by
right-clicking the Status Monitor icon in the Windows Taskbar.

Statistics
Click the Statistics tab to view information about the number of packets sent and received by the ORiNOCO
802.11a/b Combo CardBus Card.
The default Statistics screen displays the following statistics:
•
Unicast Packets Sent: This statistic reports the number of packets transmitted by the card that were destined for a single network node.
•
Multicast Packets Sent: This statistic reports the number of packets transmitted by the card that were destined for more than one network node.
•
Unicast Packets Received: This statistic reports the number of packets received that were destined only for
this card.
•
Multicast Packets Received: This statistic reports the number of packets received that were destined for
more than one network node.
You can view additional statistics by clicking Advanced Statistics; an example is shown below.
The advanced Statistics screen displays the following additional statistics:
Configuration & the ORiNOCO Utility
36
Send
•
Send Rate: This field reports the card’s current transmit rate.
•
Unicast Bytes Sent: This statistic reports the total number of bytes contained in the unicast packets transmitted by the card.
•
Multicast Bytes Sent: This statistic reports the total number of bytes contained in the multicast packets
transmitted by the card.
•
Single Retries: After the card sends a packet, it waits for an acknowledgment from the receiving radio to
confirm that the packet was successfully received. If an acknowledgment is not received within a fixed
period of time, the card will retransmit the packet. This statistic reports the number of packets that required
one retry before the card received an acknowledgment.
•
Multiple Retries: This statistic reports the number of packets that required more than one retry before the
card received an acknowledgment.
•
Excessive Retries: This statistic reports the number of packets that were not successfully transmitted
because the card did not receive an acknowledgment within the maximum number of retries.
•
Last ACK RSSI: This statistic reports the RSSI (Received Signal Strength) for the last acknowledgment (ACK)
received by the card. RSSI is reported in decibels (dB) and typically ranges from 0 to 75. In general, an RSSI
less than 15 indicates a weak signal and an RSSI greater than 30 indicates a strong signal.
•
ACK Errors: This statistic reports the number of unicast transmit attempts for which no acknowledgement
(ACK) was received.
•
CTS Errors: This statistic reports the number of Clear To Send (CTS) errors. When the card uses RTS/CTS
before transmitting a packet, it first sends a Request to Send (RTS) message to the packet’s recipient. The
packet’s recipient then returns a CTS message to the card. When the card receives the CTS, it sends the
packet to the recipient. However, if the card does not receive a CTS within a fixed period of time, it will
resend the RTS. After a fixed number of retries, the card will record a CTS Error if a CTS has not been
received.
Receive
•
Receive Rate: This field reports the data rate at which the card is currently receiving packets sent by another
wireless device (either 802.11a or 802.11b).
•
Unicast Bytes Received: This statistic reports the total number of bytes contained in the unicast packets
received by the card.
•
Multicast Bytes Received: This statistic reports the total number of bytes contained in the multicast packets
received by the card.
•
WEP Undecryptable: This statistic displays the number of packets that were discarded due to a problem
during decryption, such as mismatched WEP Keys.
•
Bad Frame Checksum: This statistic displays the number of received packets that failed the CRC (Cyclic
Redundancy Check) of the Frame Check Sequence (FCS).
•
Last Frame’s RSSI: This statistic reports the RSSI (Received Signal Strength) for the last packet received by
the card. RSSI is reported in decibels (dB) and typically ranges from 0 to 75. In general, an RSSI less than 15
indicates a weak signal and an RSSI greater than 30 indicates a strong signal.
•
Duplicate Frames: This statistic displays the number of duplicate packets received by the card. When the
card successfully receives a packet, it sends an acknowledgment (ACK) to the transmitting node. If the ACK
does not reach the transmitting node within a specified period of time after it sent the packet (due to interference or some other type of delay), it will resend the packet to the recipient. In this case, the card then
receives the packet a second time, records that it received a duplicate packet, and sends an ACK again.

The card sends a series of packets to the selected device and monitors the number of replies it receives. This
information is converted to a percentage and plotted on a graph.
Configuration & the ORiNOCO Utility
39
In addition, the utility displays the current success rate in the Instantaneous Success field and the average
success rate (since the beginning of the test) in the Average Success field.
By default, the card uses a packet size of 500 Bytes and automatically switches between all rates as necessary
during the test (greater range generally means a lower transfer rate). However, you can also specify a transfer
rate and/or a packet size (between 1 and 1500 Bytes) using the drop-down menu. If you change either the
Transfer Rate or the packet size, click Apply for these changes to take effect. Click Close to exit the Packet
Transmission Success Rate screen.

Range
Every environment is unique with different obstacles, barriers, materials, etc., and, therefore, it is difficult to
determine the exact range that will be achieved without testing. Radio signals may reflect off of some obstacles
or be absorbed by others depending on their construction.
Proper antenna placement can help improve range. Try to keep the card’s antennas free of obstructions
(particularly metal objects) and do not place a sheet of metal (like a filing cabinet) between two antennas. Also,
Proxim recommends that you use the ORiNOCO Utility to evaluate the signal strength and link quality between
the card and other wireless devices.
LED Indicators
The ORiNOCO 802.11a/b Combo CardBus Card includes two green LED indicators on the top of the card near the
antenna.
These LEDs display the following behavior:
•
Both LEDs are off when the card is not receiving power or when the ORiNOCO driver is not installed.
•
The LEDs blink in an alternating pattern when the card is searching for an Access Point (in Infrastructure
mode) or Ad Hoc network (in Ad Hoc mode).
•
The LEDs blink in unison every second when the card has associated with an Access Point or joined an Ad
Hoc network.
•
When there is network activity, the LEDs blink at a faster rate; the LEDs will blink in unison more often as the
card’s Send or Receive Rate increases.

Common Technical Support Questions
This section discusses some of the most common problems using an ORiNOCO 802.11a/b Combo CardBus Card
and offers possible solutions.
Symptom/Question
Possible Solution/Answer
I installed the adapter card in the computer before
running SETUP.EXE. What should I do?
Follow the on-screen instructions to install the card using
Microsoft’s Add New Hardware Wizard. When prompted, point the
Wizard to search the ORiNOCO Installation CD for driver files.
Then, after you have installed the driver, run SETUP.EXE from the
ORiNOCO Installation CD to install the ORiNOCO utility.
My office has an existing 802.11b network. Is the
combo card compatible?
Yes, when it is operating in 802.11b mode.
I want to install an 802.11a network in my office that
has an existing 802.11b network. Will the 802.11a
network interfere with the 802.11b network?
No. 802.11a and 802.11b devices will not interfere with each
other since they operate at different frequencies. 802.11a devices
operate in the 5 GHz band, and 802.11b devices operate in the 2.4
GHz band.
Is an ORiNOCO 802.11a/b Combo CardBus Card
compatible with 802.11a and 802.11b products from
other vendors?
Yes, the card can interoperable with 802.11a-compliant or
802.11b-compliant products from other vendors. However, if you
use 2X mode to achieve data rates up to 108 Mbps, the card is
only compatible with 802.11a products from Proxim.
In throughput tests, the card doesn’t seem to
transfer data as quickly as I’d expect.
Data rate is the raw signaling rate of a networking device; it does
not equal data throughput. Actual data throughput is always less
than the data rate since some of the available bandwidth is used
to send control messages and regulate activity over the wireless
medium. Also, throughput will depend on several factors such as
network overhead, the file transfer program in use, the
computer’s operating system, and the computer’s processor
speed.
How do I determine where to install Access Points to
ensure that users can access the wireless network
from anywhere in my facility?
Proxim recommends that you perform a site survey following the
procedure outlined in Proxim’s Introduction to Enterprise Wireless
Networking Technical Training class. If you would like to learn
more about the site survey procedure, you should consider
signing up for a Proxim Technical Training class in your area. Refer
to Proxim’s Web site at http://training.proxim.com/ for more
information.
I’ve entered my Harmony User Name and Password
but I can’t log on to the network.
Either your User Name or Password is incorrect or you are not in
range of an Access Point. To determine whether or not you are in
range of an Access Point, click Cancel to access the Windows
desktop and locate the Association State field within the
ORiNOCO Utility. Then, log on to Windows again to bring up the
Harmony logon prompt. If you are out of range of an Access Point,
check the Defer logon for current session if Access Point is
out of range box and click Logon. If your User Name or
Password is incorrect, contact your network administrator for
assistance.
Troubleshooting
45
Symptom/Question
Possible Solution/Answer
I deferred my Harmony logon until my computer was
in range of an Access Point. However, once the card
associated with an Access Point, I could not access
the network.
Open the ORiNOCO Utility’s Association Information screen and
locate the Harmony Security Protocol field. If the field reports
“User is not authenticated,” then either your User Name or
Password is incorrect. Try logging on to Windows again. If
problems persist, contact your network administrator to confirm
your User Name and Password.
My Harmony User Name and Password are
synchronized with my Windows User Name and
Password so the Harmony logon prompt does not
appear after I logon to Windows. But now I want to
change my Harmony Password. What can I do?
Change your Windows Password; the Harmony logon prompt will
reappear after you log on to Windows once your Windows
Password and Harmony Password no longer match. Otherwise,
contact your network administrator who can change your
Password via the Harmony System’s User Database.
My computer can’t reestablish a network
connection when the Harmony Security Protocol is
enabled.
You need to logon to Harmony Security first before logging on to
Windows to gain immediate access to network resources. Open
the Harmony Utility’s Security screen and place a check mark next
to the Log on to Harmony Security before Windows Logon
option. Then, save your changes and logon to Windows again.
Does the card support IEEE 802.1x Authentication?
Yes, but you cannot configure 802.1x using the ORiNOCO Utility;
you need to use a configuration utility supplied by your RADIUS
server vendor. Also, Windows XP provides native support for the
IEEE 802.1x standard.
How long will my battery last when using the
ORiNOCO 802.11a/b Combo CardBus Card?
Battery life will vary from unit to unit and depends on many
factors including battery type, length of battery life without the
CardBus Card inserted, and how frequently the CardBus Card
transmits and receives data. Frequent network activity will drain
the battery faster than if the card were left idle in doze mode.
Configuring the CardBus Card to use one of the Power Saving
modes will prolong battery life. However, you should perform
